Suicide in Surgeons: The Heavy Toll of a High-Stakes Career
For those outside the medical profession, it took a global pandemic to finally understand how pervasive distress and suicide are among medical professionals, particularly surgeons.
For James Harrop, MD, it was made real years earlier by a colleague he’d trained alongside and worked with for decades — “one of the best surgeons I’ve ever seen” who, one day, just wasn’t there.
Lost in his own work, it wasn’t until Dr. Harrop, a professor of neurological and orthopedic surgery at Thomas Jefferson University, Philadelphia, read an article in The New England Journal of Medicine and realized his friend Michael Weinstein, MD, MPH, had been profoundly depressed for years and was hospitalized for his own safety.
Dr. Weinstein recovered and later gave grand rounds at Thomas Jefferson University, where he is an associate professor of surgery in the Acute Care Surgery Division. But the story stuck with Dr. Harrop.
“I said to Mike afterward, I’ve known you for 20 years and, retrospectively, going back, I never saw a single sign that you were depressed, sad, or had any issues, and he said to me ‘that’s because I did everything I could to make sure no one knew I had a problem,’ ” Dr. Harrop said during a talk on physician suicide on May 4 at the American Association of Neurological Surgeons (AANS) 2024 Annual Meeting.
“And that scared me because we need to help these people, we need to identify who they are.”
Surgeons at Greater Risk
Among 9175 physicians surveyed in the 2023 Medscape Physician Suicide Report, 9% had considered suicide, and 1% had attempted it. The average for US adults is 4.9% and 0.5%, respectively.
Surgeons are at particularly high risk. A 2011 survey of 7905 US surgeons found that 1 in 16 (6.3%) had considered suicide in the previous year. A post-pandemic survey of more than 600 surgeons and surgical trainees reported that one in seven had suicidal ideation.
It’s often estimated that between 300 and 400 physicians die by suicide each year in the United States, but exact numbers are not known. Recent updated estimates from the National Violent Death Reporting System put the number at 119 physician suicides annually.
Notably, that’s no better than data reported more than 50 years ago in the landmark policy paper The Sick Physician: Impairment by Psychiatric Disorders, Including Alcoholism and Drug Dependence. It sounded the alarm on poor mental health in physicians and reported that 100 doctors died by suicide annually — the equivalent of the average medical school graduating class at the time.
“If I take my med school class and double it, that’s how many physicians die each year,” Dr. Harrop said. “And here’s the bad news, it starts in medical school.”
Research shows higher rates of depression and suicidal ideation in medical students and residents than in other graduates, with rates varying by stage of training, he noted.
In a multischool study, 12% of medical students and residents had probable major depression, 9.2% mild/moderate depression, and suicidal ideation jumped from 6.6% in the first year of medical school to 9.4% in year 4.
A recent AANS survey of 346 neurosurgery residents revealed 67% had burnout, and 41% seriously considered quitting. Burnout rose to a high of 76% in the second year and decreased to 49% and 54% in years 3 and 4, respectively.
Inadequate operating room exposure, hostile faculty, and stressors outside work were tied to burnout, whereas mentorship was linked to a threefold lower likelihood of burnout.
Notably, a 2019 study conservatively estimated that the annual cost of burnout-related physician turnover and reduced clinical hours was $4.6 billion nationally and $7600 per employed physician for an organization.
“We need to be kinder to each other, to look out for each other, and to talk to each other,” Dr. Harrop told conference attendees.
‘Death by a 1000 Cuts’
A host of factors are associated with physician suicide including long work hours, delayed gratification, difficulty balancing work and home life, changing healthcare systems, lawsuits, and the unique ability to prescribe medications, said Dr. Harrop.
“In my life, I think of it as death by 1000 cuts. Every day I come in, you’ve got another person attacking you,” he said, referencing Death by 1000 Cuts: Medscape National Physician Burnout & Suicide Report 2021.
Dr. Harrop told this news organization that talking with numerous experts in this field has made him appreciate that anyone is at a risk for suicide.
“The problem is an overload of external resources crushing your existence to the point that you become paralyzed and make the irrational thought that the best solution is to end your life,” he said.
Ann Stroink, MD, immediate past president of the AANS, said in an interview that one potential trigger for burnout is the current shortage of neurosurgeons in the United States, which has led to increased workloads and potential sleep deprivation among existing neurosurgeons.
“To address this critical issue, we’ve been advocating through legislative channels for additional Medicare[-funded] slots” to train more neurosurgeons, she said. “It’s imperative that we take proactive steps to ensure that our healthcare system can sustainably meet the needs of patients, while also supporting the well-being of our neurosurgical professionals.”
The AANS is also advocating for decreased regulatory burdens associated with Medicare and insurance coverage, such as prior authorization, to help alleviate the administrative burdens that often contribute to burnout among its members, Dr. Stroink said.
A Model for Suicide Prevention
Dr. Harrop emphasized that suicide is preventable and that there is “some good news.” Turning to another high-risk profession, he noted that the US Air Force was able to reduce its suicide rate by 42.7% between 1994 and 1998 by doing three basic things.
The agency established a central surveillance database, restructured prevention services, and, more importantly, began conducting annual suicide prevention and awareness training, using gatekeepers to channel at-risk personnel to appropriate agencies and performing mental health questionnaires at enrollment and annually.
Similarly, education, screening, and access to mental health treatment are core recommendations for a national response to depression and suicide in physician trainees, said Dr. Harrop, who noted that his own hospital has started using the Patient Health Questionnaire 9-item for its staff.
Asked by this news organization how much progress has been made since The Sick Physician report, Dr. Harrop said, “we are probably doing worse” in terms of the number of physician suicides, but “on a positive note, we are better with resources and acknowledgment that a problem exists.”
He noted that the AANS, which has published a physician burnout series on its Neurosurgery Blog, has shown great interest in this topic and is working to spread the word to help neurosurgeons. “My simple talk has led to me being approached by numerous people and healthcare organizations on how to further focus resources and prevention of this problem.”
Asked the one thing he would tell his friend, Michael Weinstein, a fellow surgeon, or trainee who’s struggling, Dr. Harrop said, “I am here for you, and we will get over these temporary problems, which are not significant in the big picture of what you mean to the world.”
Dr. Harrop reported serving as an adviser for Ethicon and Spiderwort.

Robotic Mastectomy Is Feasible, But Is It Safe?
a type of conservative mastectomy preserving the skin and nipple-areola complex. The new findings potentially expand the application of robotic surgery to a larger patient population but doubts about the safety of this approach linger.
Robotic Mastectomy
The first surgeries involving the Da Vinci robotic surgeon for breast removal date to 2015. Multiport robotic surgery faces significant obstacles in this field, however. Feasibility studies have primarily focused on women with small breasts, corresponding to cup size C or smaller.
In the study that was published in JAMA Surgery, surgeons used the more cost-effective single-port platform for bilateral NSM procedures. Among the 20 patients included in the analysis (age, 29-63 years), 11 underwent prophylactic mastectomy (for a high risk for cancer) and 9 had mastectomy for breast tumors. Breast sizes ranged from A cup to D cup.
The duration of the procedure, from skin incision to suture for both breasts, ranged from 205 to 351 minutes (median, 277 minutes). No immediate operative complications (eg, hematoma) occurred, and there was no need for conversion to open surgery in any case. Over the 36-month follow-up, there were no recurrences. About 95% of patients retained skin sensitivity and 55% retained nipple sensitivity.
Unanswered Questions
In an accompanying article, Monica Morrow, MD, director of surgical breast oncology at the Memorial Sloan-Kettering Cancer Center in New York, acknowledged that the new evidence confirms the surgical approach’s feasibility but deems it insufficient to adopt it lightly. “At this point, the issue is not whether robotic mastectomy can be done but whether there is sufficient information about its oncologic safety that it should be done,” she wrote.
In a 2019 statement that was updated in 2021, the US Food and Drug Administration stated, “The safety and effectiveness of using robotically assisted surgical devices in mastectomy procedures or in the prevention or treatment of breast cancer have not been established.” The significance of this caution is underscored by the experience with laparoscopic and robotic radical hysterectomies. These procedures were widely adopted until a randomized prospective study demonstrated lower disease-free and overall survival for the minimally invasive approach compared with open surgery.
The University of Texas surgeons stated that acceptable safety and oncological outcomes for robotic NSM compared with conventional NSM had been demonstrated. They cited two trials with 238 cases and a median follow-up of less than 3 years. Dr. Morrow wrote, “While these reports provide reassurance that gross residual tumor is not being left behind, they do not address the issue of failure to remove all of the breast tissue due to thick skin flaps, with the potential for development of late recurrence or new cancers.” It is worth noting that even with the traditional surgical approach, the 5-year local recurrence rate after NSM is approximately double when observed with shorter follow-ups.
According to Dr. Morrow, the high rate of sensory preservation observed with robotic surgery, a desirable outcome for patients, is also a cause for concern. “While this may be due to incision placement or minimal skin flap retraction, as suggested by the authors, it is equally plausible that this could be due to thick skin flaps with preservation of the terminal branches of the fourth intercostal nerve.”
Therefore, more information on long-term oncological outcomes in a large number of patients will be necessary to confirm the safety of the procedure. In addition, measuring patient-reported outcomes will be useful in demonstrating that the benefits of the procedure outweigh increased operating times and costs.

FROM JAMA SURGERY
Three wild technologies about to change health care
When I was a child, I watched syndicated episodes of the original “Star Trek.” I was dazzled by the space travel, sure, but also the medical technology.
A handheld “tricorder” detected diseases, while an intramuscular injector (“hypospray”) could treat them. Sickbay “biobeds” came with real-time health monitors that looked futuristic at the time but seem primitive today.
Such visions inspired a lot of us kids to pursue science. Little did we know the real-life advances many of us would see in our lifetimes.
Artificial intelligence helping to spot disease, robots performing surgery, even video calls between doctor and patient – all these once sounded fantastical but now happen in clinical care.
Now, in the 23rd year of the 21st century, you might not believe wht we’ll be capable of next. Three especially wild examples are moving closer to clinical reality.
Human hibernation
Captain America, Han Solo, and “Star Trek” villain Khan – all were preserved at low temperatures and then revived, waking up alive and well months, decades, or centuries later. These are fictional examples, to be sure, but the science they’re rooted in is real.
(In one extreme case, a climber survived after almost 9 hours of efforts to revive him.)
Useful for a space traveler? Maybe not. But it’s potentially huge for someone with life-threatening injuries from a car accident or a gunshot wound.
That’s the thinking behind a breakthrough procedure that came after decades of research on pigs and dogs, now in a clinical trial. The idea: A person with massive blood loss whose heart has stopped is injected with an ice-cold fluid, cooling them from the inside, down to about 50° F.
Doctors already induce more modest hypothermia to protect the brain and other organs after cardiac arrest and during surgery on the aortic arch (the main artery carrying blood from the heart).
But this experimental procedure – called emergency preservation and resuscitation (EPR) – goes far beyond that, dramatically “decreasing the body’s need for oxygen and blood flow,” says Samuel Tisherman, MD, a trauma surgeon at the University of Maryland Medical Center and the trial’s lead researcher. This puts the patient in a state of suspended animation that “could buy time for surgeons to stop the bleeding and save more of these patients.”
The technique has been done on at least six patients, though none were reported to survive. The trial is expected to include 20 people by the time it wraps up in December, according to the listing on the U.S. clinical trials database. Though given the strict requirements for candidates (emergency trauma victims who are not likely to survive), one can’t exactly rely on a set schedule.
Still, the technology is promising. Someday we may even use it to keep patients in suspended animation for months or years, experts predict, helping astronauts through decades-long spaceflights, or stalling death in sick patients awaiting a cure.
Artificial womb
Another sci-fi classic: growing human babies outside the womb. Think the fetus fields from “The Matrix,” or the frozen embryos in “Alien: Covenant.”
In 1923, British biologist J.B.S. Haldane coined a term for that – ectogenesis. He predicted that 70% of pregnancies would take place, from fertilization to birth, in artificial wombs by 2074. That many seems unlikely, but the timeline is on track.
Developing an embryo outside the womb is already routine in in vitro fertilization. And technology enables preterm babies to survive through much of the second half of gestation. Normal human pregnancy is 40 weeks, and the youngest preterm baby ever to survive was 21 weeks and 1 day old, just a few days younger than a smattering of others who lived.
The biggest obstacle for babies younger than that is lung viability. Mechanical ventilation can damage the lungs and lead to a chronic (sometimes fatal) lung disease known as bronchopulmonary dysplasia. Avoiding this would mean figuring out a way to maintain fetal circulation – the intricate system that delivers oxygenated blood from the placenta to the fetus via the umbilical cord. Researchers at Children’s Hospital of Philadelphia have done this using a fetal lamb.
The key to their invention is a substitute placenta: an oxygenator connected to the lamb’s umbilical cord. Tubes inserted through the umbilical vein and arteries carry oxygenated blood from the “placenta” to the fetus, and deoxygenated blood back out. The lamb resides in an artificial, fluid-filled amniotic sac until its lungs and other organs are developed.
Fertility treatment could benefit, too. “An artificial womb may substitute in situations in which a gestational carrier – surrogate – is indicated,” says Paula Amato, MD, a professor of obstetrics and gynecology at Oregon Health and Science University, Portland. (Dr. Amato is not involved in the CHOP research.) For example: when the mother is missing a uterus or can’t carry a pregnancy safely.
No date is set for clinical trials yet. But according to the research, the main difference between human and lamb may come down to size. A lamb’s umbilical vessels are larger, so feeding in a tube is easier. With today’s advances in miniaturizing surgical methods, that seems like a challenge scientists can overcome.
Messenger RNA therapeutics
Back to “Star Trek.” The hypospray injector’s contents could cure just about any disease, even one newly discovered on a strange planet. That’s not unlike messenger RNA (mRNA) technology, a breakthrough that enabled scientists to quickly develop some of the first COVID-19 vaccines.
But vaccines are just the beginning of what this technology can do.
A whole field of immunotherapy is emerging that uses mRNA to deliver instructions to produce chimeric antigen receptor–modified immune cells (CAR-modified immune cells). These cells are engineered to target diseased cells and tissues, like cancer cells and harmful fibroblasts (scar tissue) that promote fibrosis in, for example, the heart and lungs.
The field is bursting with rodent research, and clinical trials have started for treating some advanced-stage malignancies.
Actual clinical use may be years away, but if all goes well, these medicines could help treat or even cure the core medical problems facing humanity. We’re talking cancer, heart disease, neurodegenerative disease – transforming one therapy into another by simply changing the mRNA’s “nucleotide sequence,” the blueprint containing instructions telling it what to do, and what disease to attack.
As this technology matures, we may start to feel as if we’re really on “Star Trek,” where Dr. Leonard “Bones” McCoy pulls out the same device to treat just about every disease or injury.

When I was a child, I watched syndicated episodes of the original “Star Trek.” I was dazzled by the space travel, sure, but also the medical technology.
A handheld “tricorder” detected diseases, while an intramuscular injector (“hypospray”) could treat them. Sickbay “biobeds” came with real-time health monitors that looked futuristic at the time but seem primitive today.
Such visions inspired a lot of us kids to pursue science. Little did we know the real-life advances many of us would see in our lifetimes.
Artificial intelligence helping to spot disease, robots performing surgery, even video calls between doctor and patient – all these once sounded fantastical but now happen in clinical care.
Now, in the 23rd year of the 21st century, you might not believe wht we’ll be capable of next. Three especially wild examples are moving closer to clinical reality.
Human hibernation
Captain America, Han Solo, and “Star Trek” villain Khan – all were preserved at low temperatures and then revived, waking up alive and well months, decades, or centuries later. These are fictional examples, to be sure, but the science they’re rooted in is real.
(In one extreme case, a climber survived after almost 9 hours of efforts to revive him.)
Useful for a space traveler? Maybe not. But it’s potentially huge for someone with life-threatening injuries from a car accident or a gunshot wound.
That’s the thinking behind a breakthrough procedure that came after decades of research on pigs and dogs, now in a clinical trial. The idea: A person with massive blood loss whose heart has stopped is injected with an ice-cold fluid, cooling them from the inside, down to about 50° F.
Doctors already induce more modest hypothermia to protect the brain and other organs after cardiac arrest and during surgery on the aortic arch (the main artery carrying blood from the heart).
But this experimental procedure – called emergency preservation and resuscitation (EPR) – goes far beyond that, dramatically “decreasing the body’s need for oxygen and blood flow,” says Samuel Tisherman, MD, a trauma surgeon at the University of Maryland Medical Center and the trial’s lead researcher. This puts the patient in a state of suspended animation that “could buy time for surgeons to stop the bleeding and save more of these patients.”
The technique has been done on at least six patients, though none were reported to survive. The trial is expected to include 20 people by the time it wraps up in December, according to the listing on the U.S. clinical trials database. Though given the strict requirements for candidates (emergency trauma victims who are not likely to survive), one can’t exactly rely on a set schedule.
Still, the technology is promising. Someday we may even use it to keep patients in suspended animation for months or years, experts predict, helping astronauts through decades-long spaceflights, or stalling death in sick patients awaiting a cure.

Add AFib to noncardiac surgery risk evaluation: New support
Practice has gone back and forth on whether atrial fibrillation (AFib) should be considered in the preoperative cardiovascular risk (CV) evaluation of patients slated for noncardiac surgery, and the Revised Cardiac Risk Index (RCRI), currently widely used as an assessment tool, doesn’t include the arrhythmia.
But consideration of preexisting AFib along with the RCRI predicted 30-day mortality more sharply than the RCRI alone in an analysis of data covering several million patients slated for such procedures.
Indeed, AFib emerged as a significant, independent risk factor for a number of bad postoperative outcomes. Mortality within a month of the procedure climbed about 30% for patients with AFib before the noncardiac surgery. Their 30-day risks for stroke and for heart failure hospitalization went up similarly.
The addition of AFib to the RCRI significantly improved its ability to discriminate 30-day postoperative risk levels regardless of age, sex, and type of noncardiac surgery, Amgad Mentias, MD, Cleveland Clinic, told this news organization. And “it was able to correctly up-classify patients to high risk, if AFib was there, and it was able to down-classify some patients to lower risk if it wasn’t there.”
“I think [the findings] are convincing evidence that atrial fib should at least be part of the thought process for the surgical team and the medical team taking care of the patient,” said Dr. Mentias, who is senior author on the study published in the Journal of the American College of Cardiology, with lead author Sameer Prasada, MD, also of the Cleveland Clinic.
The results “call for incorporating AFib as a risk factor in perioperative risk scores for cardiovascular morbidity and mortality,” the published report states.
Supraventricular arrhythmias had been part of the Goldman Risk Index once widely used preoperatively to assess cardiac risk before practice adopted the RCRI in the past decade, observe Anne B. Curtis, MD, and Sai Krishna C. Korada, MD, University at Buffalo, New York, in an accompanying editorial.
The current findings “demonstrate improved prediction of adverse postsurgical outcomes” from supplementing the RCRI with AFib, they write. Given associations between preexisting AFib and serious cardiac events, “it is time to ‘re-revise’ the RCRI and acknowledge the importance of AFib in predicting adverse outcomes” after noncardiac surgery.
The new findings, however, aren’t all straightforward. In one result that remains a bit of a head-scratcher, postoperative risk of myocardial infarction (MI) in patients with preexisting AFib went in the opposite direction of risk for death and other CV outcomes, falling by almost 20%.
That is “hard to explain with the available data,” the report states, but “the use of anticoagulation, whether oral or parenteral (as a bridge therapy in the perioperative period), is a plausible explanation” given the frequent role of thrombosis in triggering MIs.
Consistent with such a mechanism, the group argues, the MI risk reduction was seen primarily among patients with AFib and a CHA2DS2-VASc score of 2 or higher – that is, those at highest risk for stroke and therefore most likely to be on oral anticoagulation. The MI risk reduction wasn’t seen in such patients with a CHA2DS2-VASc score of 0 or 1.
“I think that’s part of the explanation, that anticoagulation can reduce risk of MI. But it’s not the whole explanation,” Dr. Mentias said in an interview. If it were the sole mechanism, he said, then the same oral anticoagulation that protected against MI should have also cut the postoperative stroke risk. Yet that risk climbed 40% among patients with preexisting AFib.
The analysis started with 8.6 million Medicare patients with planned noncardiac surgery, seen from 2015 to 2019, of whom 16.4% had preexisting AFib. Propensity matching for demographics, urgency and type of surgery, CHA2DS2-VASc score, and RCRI index created two cohorts for comparison: 1.13 million patients with and 1.92 million without preexisting AFib.
Preexisting AFib was associated with a higher 30-day risk for death from any cause, the primary endpoint being 8.3% versus 5.8% for those without such AFib (P < .001), for an odds ratio of 1.31 (95% confidence interval, 1.30-1.32).
Corresponding 30-day ORs for other events, all significant at P < .001, were:
- 1.31 (95% CI, 1.30-1.33) for heart failure
- 1.40 (95% CI, 1.37-1.43) for stroke
- 1.59 (95% CI, 1.43-1.75) for systemic embolism
- 1.14 (95% CI, 1.13-1.16) for major bleeding
- 0.81 (95% CI, 0.79-0.82) for MI
Those with preexisting AFib also had longer hospitalizations at a median 5 days, compared with 4 days for those without such AFib (P < .001).
The study has the limitations of most any retrospective cohort analysis. Other limitations, the report notes, include lack of information on any antiarrhythmic meds given during hospitalization or type of AFib.
For example, AFib that is permanent – compared with paroxysmal or persistent – may be associated with more atrial fibrosis, greater atrial dilatation, “and probably higher pressures inside the heart,” Dr. Mentias observed.
“That’s not always the case, but that’s the notion. So presumably people with persistent or permanent atrial fib would have more advanced heart disease, and that could imply more risk. But we did not have that kind of data.”
Dr. Mentias and Dr. Prasada report no relevant financial relationships; disclosures for the other authors are in the report. Dr. Curtis discloses serving on advisory boards for Abbott, Janssen Pharmaceuticals, Sanofi, and Milestone Pharmaceuticals; receiving honoraria for speaking from Medtronic and Zoll; and serving on a data-monitoring board for Medtronic. Dr. Korada reports he has no relevant financial relationships.

Nap length linked to cognitive changes
No wonder we feel worse after naps
Some of us have hectic schedules that may make a nap feel more necessary. It’s common knowledge that naps shouldn’t be too long – maybe 20 minutes or so – but if you frequently take 3-hour naps and wake up thinking you’re late for school even though you’re 47 and have your PhD, this LOTME is for you.
Studies have shown that there is a link between napping during the day and Alzheimer’s/cognitive decline, but now we’ve got a double whammy for you: Longer and more frequent napping is linked to worse cognition after a year, and in turn, those with cognitive decline and Alzheimer’s are known to nap longer and more frequently during the day.
“We now know that the pathology related to cognitive decline can cause other changes in function,” he said. “It’s really a multisystem disorder, also including difficulty sleeping, changes in movement, changes in body composition, depression symptoms, behavioral changes, etc.,” coauthor Aron Buchman, MD, said in a statement from Rush University Medical Center.
The investigators monitored 1,400 patients over the course of 14 years with wrist bracelets that recorded when a person was not active during the day and considered that a nap.
At the beginning of the study, 75% of the study subjects had no cognitive impairment, 19.5% had some cognitive impairment, and approximately 4% had Alzheimer’s. Napping during the day only increased about 11 minutes a year for those with no signs of cognitive impairment, but those who showed significantly more signs of cognitive decline doubled their nap time and those actually diagnosed with Alzheimer’s tripled theirs.
The investigators did not imply that napping causes Alzheimer’s, but they noted that people who are older and nap more than an hour a day are 40% more likely to be at risk. It is something to consider and monitor.
Sometimes, after all, a nap seems like the best idea ever, but more often than not we wake up feeling 10 times worse. Our bodies may be giving us a heads up.
Pokemon Go away depression
The summer of 2016 was a great time if you happened to be a fan of Pokemon. Which is quite a lot of people. For almost 20 years millions have enjoyed the games and animated series, but Pokemon Go brought the thrill of catching Pokemon to life in a whole new way. For the first time, you could go out into the world and pretend you were a real Pokemon trainer, and everywhere you went, there would be others like you.
The ability to chase after Pikachu and Charizard in real life (well, augmented reality, but close enough) seemed to bring people a lot of joy, but seemed is never good enough for science. Can’t have anecdotes, we need data! So researchers at the London School of Economics and Political Science conducted a study into how Pokemon Go affected local Internet search rates of depression as the game was released slowly around the world.
Through analyzing Google Trend data of words like “depression,” “anxiety,” and “stress,” the researchers found that the release of Pokemon Go was significantly associated with a noticeable, though short-term, drop in depression-related Internet searches. Location-based augmented reality games may alleviate symptoms of mild depression, the researchers said, as they encourage physical activity, face-to-face socialization, and exposure to nature, though they added that simply going outside is likely not enough to combat clinical cases of severe depression.
Still, augmented reality games represent a viable target for public health investment, since they’re easy to use and inexpensive to make. That said, we’re not sure we want the FDA or CDC making a new Pokemon Go game. They’d probably end up filling the streets with Mr. Mime. And no one would leave their house for that.

How many times has this happened to you? You need to repair a jet engine, inspect a nuclear reactor cooling system, AND perform bowel surgery, but you can’t carry around all the heavy, old-fashioned tools needed for those jobs.
Well, we’ve got one tool that can do it all! And that tool is a snake. No, it’s a robot.
It’s both! It’s the COntinuum roBot for Remote Applications. COBRA is the robot that looks like a snake! A snake that’s 5 meters long but only as thick as a pencil (about 9 mm in diameter). A robot with “extraordinary manoeuvrability and responsiveness due to … a compliant-joint structure and multiple continuous sections that enable it to bend at around 90 degrees,” according to the team at the University of Nottingham (England) that developed it.
COBRA comes equipped with a stereovision camera and a miniature cutting tool to perform complex industrial repair, but other devices can be interchanged for possible medical use.
COBRA and its joystick-like controller were designed to be easy to use. Dr. Oladejo Olaleye, the ear, nose, and throat and robotic surgeon at University Hospitals of Leicester who is directing its surgical development, was able to use COBRA on a dummy after just 5 minutes of training. He called it “the future of diagnostic endoscopy and therapeutic surgery.”
Don’t be the last aircraft engineer/nuclear technician/surgeon on your block to have this ultraslender, ultramaneuverable reptilian repair robot. Get your COBRA now! Operators are standing by.

As long as there have been people, there have been parasitic worms living in their guts. Helminth infection is a continuing and largely ignored crisis in poor, tropical nations, though worm-based diseases have been basically eliminated from wealthier countries.
This wasn’t always the case, however, as a study published in PLOS Neglected Tropical Diseases (now there’s a specific topic) has found. The researchers detail the glorious history of helminth infestation in the United Kingdom from the Victorian era all the way back to prehistory, scouring hundreds of skeletons found in 17 sites across the country for eggs, which can remain intact for thousands of years.
The researchers found that two eras in particular had very high rates of infection. Unsurprisingly, the late medieval era was one of them, but the other is less obvious. The Romans were famous for their hygiene, their baths, and their plumbing, but maybe they also should be famous for the abundance of worms in their bellies. That doesn’t make sense at first: Shouldn’t good hygiene lower infection? The benefits of a good sewer system, however, are lessened when the waste containing said infectious organisms is used to fertilize crops. Recycling is generally a good thing, but less so when you’re recycling parasitic worms.
Curiously, of the three sites from the industrial age, only the one in London had high levels of worm infestation. Considering how dirty and cramped 19th-century British cities were, one might expect disease to run rampant (tuberculosis certainly did), but the sites in Oxford and Birmingham were almost devoid of worms. The researchers theorized that this was because of access to clean well water. Or maybe worms just have a thing for London. [Editor’s note: It’s probably not that.]

Robotics lightens load for bariatric surgeons in super obese
Use of a robotics platform provides a surgeon with more information so they can make better decisions, especially in challenging situations of primary and revisional bariatric surgery, according to Cheguevara Afaneh, MD, of New York–Presbyterian Hospital and Weill Cornell Medical Center, New York.
“The value of modern technology is to be able to do the most difficult cases in a much simpler format,” he said in a presentation at the virtual Annual Minimally Invasive Surgery Symposium by Global Academy for Medical Education.
Dr. Afaneh shared examples of how robotic assistance can help surgeons address challenges in bariatric surgery clinical practice, including managing super- and super-super-obese patients, dealing with gastroesophageal reflux disease (GERD), and negating the impact of surgical assistant experience.
“Super-obese patients pose more of a challenge interoperatively for both the surgeon and the assistant,” Dr. Afaneh noted. He and colleagues conducted a study of perioperative outcomes and found no significant differences between morbidly obese and super-obese patients in perioperative morbidity or operating time when a robotic platform was used.
The benefits to the surgeon when using robotic assistance in super-obese patients include effortless navigation of the abdominal wall, the ability to execute complex maneuvers in a challenging environment, and the security of a stable platform with no assistant fatigue, Dr. Afaneh emphasized. “When you are using the robotic platform, you are negating a lot of the patient factors” and fatigue factors that make bariatric surgery in super-obese and super-super-obese patients especially difficult, he said.
For example, in a patient who weighed nearly 500 pounds, pulling up on the stomach to get behind the actual stomach is easier because assistant fatigue is not a factor, so the surgeon can take more time and prevent a more difficult dissection, he said. In addition, Dr. Afaneh’s research showed no difference in operative time, and that the robot assistance outcomes were reproducible across a range of body mass index categories.
Robotic assistance also allows for comparable outcomes in surgeons with less experience, notably in revisional surgery, said Dr. Afaneh. He reviewed data from his first year of experience in revisional procedures using robotic assistance to his partners’ more than 20 years of laparoscopic experience. He found no significant differences in operative time, complications, or conversions to open procedures.
However, the more important message from the study was that less experienced surgeons were able to safely perform some of the most difficult revisional procedures without increasing morbidity, compared with more experienced surgeons. The data suggest that, with robotic assistance, surgeons early in their career can take on some of the bigger cases and expect outcomes similar to those of more experienced surgeons, Dr. Afaneh said.
Robotics has demonstrated improved outcomes in managing patients with GERD, which has become a common problem after bariatric surgery, noted Dr. Afaneh. When he and his colleagues reviewed data from their center on robotic-assisted approaches to GERD after bariatric surgery, they found that, even in primary magnetic sphincter operations, “robotics maintains comparable outcomes in revisional sleeve gastrectomy fields,” he said.
Another notable benefit of robotics in bariatric surgery is the negation of the “assistant effect,” said Dr. Afaneh. Often, less experienced surgeons are matched with less experienced assistants. “We took a look at the use of the robotic in cases of complex GI surgeries,” he said. They compared laparoscopic and robotic cases and stratified them by third-year assistant or fellow. “If you had a fellow, the operative time dropped by half an hour for laparoscopic cases, but the time was no different in robotics cases,” regardless of the use of fellow or third-year assistant, he said.
“The robotic platform allows you to assist yourself,” and allows for full surgeon autonomy, Dr. Afaneh emphasized. “You are the best person at predicting your next step.” The robotics platform also serves as a teaching tool. “For those who teach, there is no added morbidity based on the assistance of the trainee,” he said. In addition, the improved visualization of robotics “allows for better appreciation of scarred tissue planes and more precise suturing,” he noted.
Overall, “one of the values of the robotic platform is shortening the learning curve,” Dr. Afaneh said. He reviewed data from his fellows and himself, and found no difference in operative times. “My mentee was able to achieve operative times as good as my third year in practice. The robotic platform shaved off several years of learning experience,” he said. Dr. Afaneh’s operative times also decreased with robotics, which shows how experienced surgeons learn from this technology, he said.

Practice makes better: Robotic lobectomy can shorten OR times
A new single-surgeon study suggests that and shave about 90 minutes off adjusted operating time.
The findings provide “further support to the adaptation of formalized robotic training and credentialing procedures,” wrote the authors of the retrospective, single-center study, which was presented at the 2018 Academic Surgical Congress and published in Surgery.
According to the study authors, advantages of robotic surgery, compared with thoracoscopic surgery, include “3-dimensional visualization, enhanced maneuverability in small spaces, and the ease of the hilar and mediastinal dissection. Disadvantages include the lack of haptic feedback, increased cost, and increased operative time.”
In the new study, the authors, led by thoracic surgeon Brian N. Arnold, MD, of Yale University, New Haven, Conn., attempted to quantify the learning curve in RATS pulmonary lobectomies by using a more “statistically rigorous” technique than previous studies.
The study tracked 101 of 116 consecutive patients who underwent RATS pulmonary lobectomy at a single unnamed center from 2010 to 2016. Some patients, such as those who underwent a right middle lobectomy that is considered an easier procedure, were excluded. All patients were treated by the same unidentified surgeon.
Researchers identified three phases of the RATS learning curve: cases 1-22, cases 23-63, and cases 64-101.
On average, the patients were aged 69 years; 52% were female. Overall, a third of the patients developed complications.
After controlling for various factors, the researchers found that adjusted operating time and estimated blood loss were statistically different between the first and second phases (P less than .05 and P = .016, respectively). They were also different between the first and third phases (P less than .05 and P = .006, respectively).
Specifically, operating time in the first phase was a mean of 256 minutes versus 195 minutes in the second phase (P = .0002) and 168 minutes in the third phase (P less than .0001). Blood loss was 200 mL (interquartile range, 150-300 mL) in the first phase versus 150 mL (IQR, 75-200 mL; P = .0219) in the second phase and 150 mL (IQR, 100-150 mL; P = .0096) in the third phase.
The researchers found no statistically significant evidence that the surgeon’s growing experience affected length of stay, postoperative complications, chest tube duration, or conversion rate. No patients died within 30 or 90 days.
The researchers also compared operating time, length of stay, and complication rate in the RATS procedures with those in video-assisted thoracoscopic (VATS) lobectomies performed at the same institution from 2008 to 2014. There was only a statistically significant difference in mean operating time (RATS, 319 minutes; VATS, 253 minutes; P less than .001)
The study authors noted that the surgeon had extensive previous experience with VATS procedures. “Therefore, for better or for worse, the results may not apply to surgeons without this experience who move from open surgery to robotic surgery.”

Liver resection outcomes similar for robotic and open surgery
according to researchers who conducted a recent multi-institutional analysis.
The proportion of margin-negative resections was 92% in a series of 59 patients who underwent resection at one of three tertiary hospitals, the study authors reported.
The 3-year disease-free survival and overall survival rates were 41.9% and 66%, respectively, in the 44 patients for whom longer-term follow-up was available, according to the investigators, led by Francesco Guerra, MD, of Ospedali Riuniti Marche Nord Hospital in Pesaro, Italy.
“These findings are consistent with those of patients resected via conventional laparoscopy or open surgery in contemporary series,” Dr. Guerra and his coauthors wrote in a report published in Surgical Oncology.
It’s still a matter of debate, however, whether robotic surgery has clear advantages over conventional laparoscopy for liver surgery, according to the investigators. Direct comparisons of robotic versus conventional laparoscopic liver resection are scarce, with most available data stemming from often heterogeneous case-control series with no long-term oncologic outcome data.
“Most centers have consolidated experience either in laparoscopic or in robotic liver resection,” the authors wrote. “Hence, reliable comparative analyses are likely difficult to carry out.”
Because of the scarcity of results, Dr. Guerra and his colleagues sought to investigate short- and long-term outcomes for a consecutive series of 59 patients who underwent minimally invasive, ultrasound-guided robotic surgery between 2008 and 2018 at one of three tertiary facilities. Each procedure had been performed by surgeons experienced in both liver surgery and robotics. The median age of patients undergoing the procedure was 64 years, 63% were male, and the median body mass index was 26 kg/m2.
Almost half the patients (46%) had multiple lesions removed, while about one-quarter had concomitant procedures, mainly cholecystectomy, according to the report.
Robotic surgeries were converted to open procedures in seven patients, or about 12%, a statistic comparable with other reports of laparoscopic or robotic surgery, the investigators noted.
Postoperative complications were seen in 16 patients, or 27%. That included 13 patients with class I-II complications and 3 patients with class III-IV complications, including 2 cases of heart failure and 1 case of postoperative bile leak requiring radiologic and endoscopic therapy.
The reported 3-year disease-free and overall survival of 41.9% and 66.1% was based on a mean follow-up of 19.5 months in 44 patients for whom longer-term data were available. There were 16 cases of recurrent disease, including 10 patients with evidence of liver recurrence.
“Taken together, our data show that robotics is an effective option to resect colorectal liver metastases, providing an oncological outcome similar to that of laparoscopy and open surgery,” the investigators wrote.
Dr. Guerra and colleagues reported no disclosures related to their research.

Clinical trial: AVATaR studies pulmonary complications following robotic surgery
A trial is underway to assess the incidence of postoperative pulmonary complications in patients undergoing and to study current practices of mechanical ventilation and the potential link between ventilatory parameters and postoperative pulmonary complications.
The Assessment of Ventilatory Management During General Anesthesia for Robotic Surgery (AVATaR) trial is an international observational, prospective study involving more than a dozen institutions in the United States and elsewhere, with the goal of eventually recruiting 40-50 institutions worldwide. Enrollment of consecutive patients undergoing mechanical ventilation for robotic surgery is ongoing. Exclusions are pregnant patients and those procedures not carried out in the OR.
A predefined composite of pulmonary complications was the primary outcome measured. These predefined complications are recorded regularly from medical chart until the first 5 postoperative days, discharge from hospital, or death, whatever comes first.
For full details and recruitment information on the AVATaR study (NCT02989415), go to clinicaltrials.gov.

Robotic sleeve gastrectomy may heighten organ space infection risk
While most outcomes are similar between robotic surgery and laparoscopic surgery for sleeve gastrectomy, the robotic approach carried a greater risk of organ space infection, according to the findings from a large clinical trial of more than 100,000 patients.
The study’s authors analyzed 107,726 sleeve gastrectomy operations in the Metabolic and Bariatric Surgery Association and Quality Improvement Program data registry (MBSAQIP), 7,385 of which were robotic sleeve gastrectomy (RSG). Peter William Lundberg, MD, and his coauthors of St. Luke’s University Health Network, Bethlehem, Pa., evaluated the safety of RSG vs. laparoscopic sleeve gastrectomy (LSG). The study was the first and largest comparing the two approaches to sleeve gastrectomy, the researchers noted.
“According to the MBSAQIP database, the robotic approach demonstrates a significantly higher rate of organ space infection while trending toward a lower rate of bleeding and 30-day reoperation and intervention,” Dr. Lundberg and his coauthors said.
Overall mortality was 0.07% in both groups (P = .49). The overall rates of significant adverse events were similar in both groups – 1.3% for LSG and 1.1% for RSG (P = .14) – as were bleeding rates – 0.5% and 0.4% (P = .003), respectively. The investigators characterized the slightly lower rates for RSG as “insignificant.”
RSG, however, had three times the rate of organ space infection than did the laparoscopic approach, 0.3% vs. 0.1% (P = .79). “Considering the enthusiasm with which robotics has been adopted by some bariatric surgeons, this is a sobering finding,” Dr. Lundberg noted.
The study determined that the use of staple-line reinforcement (SLR) alone significantly reduced the rate of bleeding regardless of approach by 31% on average (P = .0005). “This risk reduction was enhanced when SLR was combined with oversewing of the staple line,” Dr. Lundberg and his colleagues noted – an average reduction of 42% (P = .0009).
RSG took longer on average, 89 minutes vs. 63 minutes (P less than .0001), and the average length of stay was almost identical, 1.7 for RSG vs. 1.6 days for LSG. Reoperation rates within 30 days were also similar: 0.7% for RSG vs. 0.8% for LSG (P = .003).
“As surgeons continue to adopt and develop new technology, ongoing monitoring and reporting of safety and outcomes data are advised to maintain the high standards for outcomes in bariatric surgery,” Dr. Lundberg and his coauthors said.
The study researchers had no financial conflicts.
