Early evidence shows that surgery can alter gut microbiome
SAN DIEGO – Surgery appears to stimulate abrupt changes in both the skin and gut microbiome, which in some patients may increase the risk of surgical site infections and anastomotic leaks. With that knowledge, researchers are exploring the very first steps toward a presurgical microbiome optimization protocol, Heidi Nelson, MD, FACS, said at the annual clinical congress of the American College of Surgeons.
It’s very early in the journey, said Dr. Nelson, the Fred C. Andersen Professor of Surgery at Mayo Clinic, Rochester. Minn. And it won’t be a straightforward path: The human microbiome appears to be nearly as individually unique as the human fingerprint, so presurgical protocols might have to be individually tailored to each patient.
Dr. Nelson comoderated a session exploring this topic with John Alverdy, MD, FACS, of the University of Chicago. The panel discussed human and animal studies suggesting that the stress of surgery, when combined with subclinical ischemia and any baseline physiologic stress (chronic illness or radiation, for example) can cause some commensals to begin producing collagenase – a change that endangers even surgically sound anastomoses.
“It’s well known that bacteria can change their function in response to host stress,” said Dr. Shogan, a colorectal surgeon at the University of Chicago. “They recognize these factors and change their entire function. In our work, we found that Enterococcus began to express a tissue-destroying phenotype in response to subclinical ischemia related to surgery.”
The pathogenic flip doesn’t occur unless there are a couple of predisposing factors, he theorized. “There have to be multiple stresses involved. These could include smoking, steroids, obesity, and prior exposure to radiation – all things that we commonly see in our colorectal surgery patients. But when the right situation developed, we can see a proliferation of collagen-destroying bacteria that predispose to leaks.”
The skin microbiome is altered as well, with areas around abdominal incisions beginning to express gut flora, which increase the risk of a surgical site infection, said Andrew Yeh, MD, a general surgery resident at the University of Pittsburgh.
He presented data on 28 colorectal surgery patients, detailing perioperative changes in the chest and abdominal skin microbiome. All of the subjects were adults undergoing colon resection who had not been on any antibiotics at least 1 month before surgery. Skin sampling was performed before and after opening, with additional postoperative skin samples taken daily while the patient was in the hospital recovering. Dr. Yeh had DNA/RNA data on 431 samples taken from this group.
“We saw increases in Staphylococcus and Bacteroides on the skin – normally part of the gut microflora – in relative abundance, while Corynebacterium, a normal constituent of the skin microbiome, had decreased.”
These are all very early observations, though, and the surgical community is nowhere near being able to make any specific presurgical recommendations to optimize the microbiome, or postsurgical recommendations to manage it, said Neil Hyman, MD, FACS, professor of surgery at the University of Chicago.
While it does appear that good bacteria “gone bad” are associated with anastomotic leaks, he agreed that the right constellation of factors has to be in place for this to happen, including “the right bacteria [Enterococcus], the right virulence genes [collagenase], the right activating cures [long operation, blood loss], and the wrong microbiome [altered by smoking, chemotherapy, radiation, or other chronic stressors].”
“I think it’s safe to say that developing collagenase-producing bacteria at an anastomosis site is a bad thing, but the individual genetic makeup of every patient makes any one-size-fits-all protocol approach to treatment really problematic,” Dr. Hyman said.

EXPERT ANALYSIS FROM THE ACS CLINICAL CONGRESS
Hypothyroidism carries higher surgical risk not captured by calculator
VICTORIA, B.C. – Even with contemporary anesthesia and surgical techniques, patients who are overtly hypothyroid at the time of major surgery have a rockier course, suggests a retrospective cohort study of 58 patients in a poster presentation at the annual meeting of the American Thyroid Association.
Actual length of stay for hypothyroid patients was twice that predicted by a commonly used risk calculator, whereas actual and predicted stays aligned well for euthyroid patients. The hypothyroid group had more cases of postoperative atrial fibrillation, ileus, reintubation, and death, although numbers were too small for statistical comparison.
“This will have an impact on how we look at patients, especially from a hospital standpoint and management. That’s quite a bit longer stay and quite a bit more cost. And the longer you stay, the more complications you have, too, so it could be riskier for the patient as well,” said first author Raquel Villavicencio, MD, a fellow at Indiana University at the time of the study, and now a clinical endocrinologist at Community Hospital in Indianapolis.
“Although we don’t consider hypothyroidism an absolute contraindication to surgery, especially if it’s necessary surgery, certainly anybody who is having elective surgery should have it postponed, in our opinion, until they are rendered euthyroid,” she said. “More studies are needed to look at this a little bit closer.”
Explaining the study’s rationale, Dr. Villavicencio noted, “This was a question that came up maybe three or four times a year, where we would get a hypothyroid patient and had to decide whether or not to clear them for surgery.”
Previous studies conducted at large institutions, the Mayo Clinic and Massachusetts General Hospital, had conflicting findings and were done about 30 years ago, she said. Anesthesia and surgical care have improved substantially since then, leading the investigators to hypothesize that hypothyroidism would not carry higher surgical risk today.
Dr. Villavicencio and her coinvestigator, Cary Mariash, MD, used their institutional database to identify 29 adult patients with a thyroid-stimulating hormone (TSH) level of greater than 10 mcU/mL alone or with a TSH level exceeding the upper limit of normal along with a free thyroxine (T4) level of less than 0.6 ng/dL who underwent surgery during 2010-2015. They matched each patient on age, sex, and surgical procedure with a control euthyroid patient.
The mean TSH level in the hypothyroid group was 29.2 mcU/mL. The majority of patients in each group – 59% of the hypothyroid group and 62% of the euthyroid group – had an American Surgical Association class of 3, denoting that this was a fairly sick population. The groups were generally similar on rates of comorbidity, except that the euthyroid patients had a slightly higher prevalence of obstructive sleep apnea.
In both groups, the majority of procedures were laparotomy and/or bowel resection; pharyngolaryngectomy and esophagectomy/esophagoplasty; and wound or bone debridement.
Main results showed that in the hypothyroid group, hospital length of stay predicted with the American College of Surgeons National Surgical Quality Improvement Program surgical risk calculator was 6.9 days, but actual length of stay was 14.4 days (P = .0004). In contrast, in the euthyroid group, predicted length of stay was a similar at 7.1 days, and actual length of stay was statistically indistinguishable at 9.2 days (P = .1).
“Hypothyroidism is not taken into account with this calculator,” Dr. Villavicencio noted, adding that she was unaware of any surgical calculators that do.
One patient in the hypothyroid group died, compared with none in the euthyroid group. In terms of postoperative cardiac complications, two patients in the hypothyroid group experienced atrial fibrillation, and there was one case of pulseless electrical–activity arrest in each group.
The groups did not differ on incidence of hypothermia, bradycardia, hyponatremia, time to extubation, and hypotension. However, mean arterial pressure tended to be lower in the hypothyroid group (51 mm Hg) than in the euthyroid group (56 mm Hg), and the former more often needed vasopressors. Furthermore, postoperative ileus and reintubation were more common in the hypothyroid group.
“I think that there are kind of a lot of little things that add up to explain [the longer stay],” said Dr. Villavicencio, who disclosed that she had no relevant conflicts of interest.

State regulations for tattoo facilities increased blood donor pools
SAN DIEGO – Tattoos are rapidly moving into mainstream America, and as more states regulate tattoo facilities, persons with tattoos can be blood donors without compromising patient safety, Mary Townsend of Blood Systems Inc. reported at the annual meeting of the American Association of Blood Banks.
“Two big states – Arizona and California – were added to the list of approved states, and we had a gain of 2,216 donors in California during a 3-month period and a gain of 4,035 donors in Arizona over 4 months,” Ms. Townsend said.
Both the AABB and the Food and Drug Administration require a 12-month deferral of donors after they have received tattoos using nonsterile needles or reusable ink. The FDA’s current 2015 guidance also states that tattooed donors can give plasma as soon as the inked area has healed if they reside in a state with applied inspections and licenses for tattoo facilities, and if a sterile needle and ink were used.
Blood Systems monitors state regulations to see if they require tattoo establishments to be licensed and require the use of sterile needles and non-reusable ink. To be considered an approved state, the regulations have to be statewide, covering all jurisdictions.
In the study, Ms. Townsend and her colleagues compared the rates of donors who were deferred before and after Arizona and California were added to the list of approved states, to determine the potential gain in donors with changes in state tattoo licensing regulations.
They analyzed blood centers in California and Arizona before and after implementation of state tattoo regulations, and also screened individuals who had received tattoos in those states with the question: “In the past 12 months have you had a tattoo?” and if the answer was ‘yes,’ if the tattoo was applied by a state regulated facility.
For California, they compared two periods – 3 months before regulations were implemented (February to April of 2015) and 3 months after (February to April of 2016) regulations were implemented. For Arizona, they selected a 4-month period (December 2015 to March 2016) and 4 months afterward (December 2016 to March 2017).
A higher proportion of donors who came to centers to donate blood admitted to having gotten a tattoo within the last 12 months in the postregulatory period in both states. The increase in donors occurred immediately following the addition of both states to the Acceptable States List. Accepted donors increased 13-fold in California and 3-fold in Arizona. The absolute number of accepted donors with tattoos rose from 13 to 567 in California and from 151 to 1,496 in Arizona, which represented an annual potential gain of 2,216 and 4,035 additional blood donations.
For blood donors who received a tattoo in a regulated state, blood donations were reviewed for the presence of infectious disease markers including HIV, hepatitis B, and hepatitis C. All donors who had received a tattoo in a regulated state tested negative for HIV, HBV, and HCV.
“Roughly one in three people (in the United States) have a tattoo and, of those, about 70% have more than one tattoo. The bottom line is that 45 million Americans have at least one tattoo,” she said. As state regulations adhere to guidelines regarding tattoos and blood donation, the pool of donors increases.

VIDEO: How to manage surgical pain in opioid addiction treatment
NEW ORLEANS – How do you manage surgical pain when someone is in treatment for opioid addiction? And how do you manage chronic pain?
It is possible to give patients opioids for post-op pain without increasing the risk of relapse, according to Margaret Chaplin, MD, a staff psychiatrist at Community Mental Health Affiliates in New Britain, Conn.

Session highlights controversies in diverticulitis management
SAN DIEGO – During the annual clinical congress of the American College of Surgeons, a panel of experts discussed a wide range of evolving controversies in the management of complicated diverticulitis.
John Migaly, MD, kicked off the session by exploring the current evidence for laparoscopic lavage versus primary resection for Hinchey III diverticulitis. “Over the past two decades there has been a growing utilization of primary resection and reanastomoses with or without the use of ileostomy,” said Dr. Migaly, director of the general surgery residency program at Duke University, Durham, N.C. “And most recently over the last 5 or 10 years there’s been growing enthusiasm for laparoscopic lavage for Hinchey III diverticulitis. The enthusiasm for this procedure is based on [its accessibility] to all of us who operate on the colon in the acute setting.”
The DILALA trial makes the best case for laparoscopic lavage, “but it doesn’t make a very good one,” he commented. The trial was conducted in nine surgical departments in Sweden and Denmark (Ann Surg. 2016;263[1]:117-22). Hinchey III patients were randomized 1:1 to laparoscopic lavage or the Hartmann procedure. The primary outcome was reoperations within 12 months. An early analysis of the short-term outcomes in 83 patients found similar 30-day and 90-day mortality and morbidity. Its authors concluded that laparoscopic lavage had equivalent morbidity and mortality compared with radical resection, shorter operative time, shorter time in the recovery unit, a shorter hospital stay, but no difference in the rate of reoperation.
“It was found to be safe and feasible,” Dr. Migaly said. One year later, the researchers presented their 12-month outcomes and came to the same conclusions. Limitations of the data are that it was conducted in nine centers “but they enrolled only 83 patients, so it seems underpowered,” he said. “And there was no mention of the incidence of abdominal abscess requiring percutaneous drainage or episodes of diverticulitis. The data seem a little less granular than the LADIES trial.”
The SCANDIV trial is the largest study on the topic to date, a randomized clinical superiority trial conducted at 21 centers in Sweden and Norway (JAMA 2015;314[13]:1364-75). Of the 509 patients screened, 415 were eligible and 199 were enrolled: 101 to laparoscopic lavage, 98 to colon resection. The primary endpoint was severe postoperative complications within 90 days, defined as a Clavien-Dindo score of over 3. The researchers found no difference in major complications nor in 90-day mortality between the two groups. The rate of reoperation was significantly higher in the lavage group, compared with the resection group (20.3% vs. 5.7%, respectively). Four sigmoid cancers were missed in the lavage group and, while the length of operation was significantly shorter in the lavage group, there were no differences between the two groups in hospital length of stay or quality of life.
A meta-analysis of the three randomized controlled trials that Dr. Migaly reviewed concluded that laparoscopic lavage, compared with resection, for Hinchey III diverticulitis increased the rate of total reoperations, the rate of reoperation for infection, and the rate of subsequent percutaneous drainage (J Gastrointest Surg 2017;21[9]:1491-99). A larger, more recent meta-analysis of 589 patients, including the three randomized controlled trials that Dr. Migaly discussed, concluded that laparoscopic lavage patients, compared with resection patients, had three times the risk of persistent peritonitis, intra-abdominal abscess, and emergency reoperative surgery. “Therefore, a reasonable conclusion would be that data at this point does not support the use of laparoscopic lavage,” he said.
The initial procedure of choice for most patients is abscess drainage via CT-guided percutaneous drainage. “There are some patients who are not candidates for percutaneous drainage, [such as] if the abscess is not accessible to the radiologist, if the patient is anticoagulated, and if the patient requires emergent surgical intervention irrespective of the abscess,” said Dr. Maron, a colorectal surgeon who practices at Cleveland Clinic Florida, Weston. “There is also a question of cavity size. Most authors in the literature use a cut-off of 3-4 cm.”
The goal is complete drainage of the abscess, and sometimes multiple catheters will be required. One study found that predictors of successful abscess drainage included having a well-defined, unilocular abscess. The success rate fell to 63% for patients who presented with more complex abscesses, including those that were loculated, poorly defined, associated with a fistula, and contained feces or semisolid material (Dis Colon Rectum. 1997;40:1009-13).
The 2014 ASCRS Practice Parameters includes the recommendation that elective colectomy should typically be considered after the patient recovers from an episode of complicated diverticulitis, “but some of the data may be calling that into question,” Dr. Maron said. In one series of 18 patients with an abscess treated percutaneously, 11 refused surgery and 7 had significant comorbidity (Dis Colon Rectum. 2014;57:331-6). Three patients died of a pre-existing condition and 7 of the 15 surviving patients had recurrent diverticulitis. Three underwent surgery and four were treated medically. The authors found no association between long-term failure and abscess location or previous episodes of diverticulitis.
In a larger study, researchers identified 218 patients who were initially treated with intravenous antibiotics and percutaneous drain (Dis Colon Rectum. 2013;56:622-6). About 10% of the patients required an urgent operation, while most of the other patients underwent elective resection, but 15% of patients did not undergo a subsequent colectomy. “Most of these patients were medically unfit to undergo surgery,” he noted. Abscess location was more commonly paracolic than pelvic. The mean abscess size was 4.2 cm, and the drain was left in for a median of 20 days. The recurrence rate in this series was only 30%, but none of the recurrences required surgery. The authors found that abscesses greater than 5 cm in size were associated with a greater risk of recurrence (P = .003). They concluded that observation after percutaneous drainage is safe in selected patients.
Based on results from this and other more recent studies, Dr. Maron said that it remains unclear whether surgeons should wait and watch or operate after successful percutaneous drainage of diverticular abscess. The data are “not as robust as we’d like … most of these are retrospective studies,” he said. “There’s quite a bit of inherent selection bias, and there is no standardization with regard to length of time of percutaneous drain, rationale for nonoperative management versus elective colectomy. What we do know is that there are some patients who can be managed safely without surgery. Unfortunately, there is no good algorithm I can offer you: Perhaps larger abscesses can portend a higher recurrence. I don’t think we’ll have a good answer to this until we perform a prospective randomized trial. However, we may learn some data from patients managed by peritoneal lavage and drain placement.”
Next, consider how to perform the procedure: laparoscopic or open? “But again, you’re going to look at how stable your patient is, what your skill set is, what equipment is available, and if the patient has had previous abdominal surgeries,” she advised. “In the traditional Hartmann procedure, you resect the perforated segment. You try not to open any tissue planes that you don’t have to. You do just enough so you can bring up a colostomy; you close the rectum or you make a mucous fistula. The problem with this operation is that up to 80% of these patients have their colostomy closed. That is why there is all this controversy. If there is any question, this [procedure] is always the safest option; there’s no anastomosis.”
What about a performing resection and a colorectal anastomosis? This is usually done more commonly in the elective situation, “when things are perfect, when you have healthy tissue,” Dr. Hull said. “If you do it in the emergent situation you have to think to yourself, ‘Could my patient tolerate a leak?’ You won’t want to do this operation on a 72-year-old who’s on steroids for chronic pulmonary disease and has coronary artery disease, because if they had a leak, they’d probably die.”
The third procedural option is to resect bowel (usually sigmoid) with colorectal anastomosis and diversion (loop ileostomy). “This is always my preferred choice,” Dr. Hull said. “I always am thinking, ‘Why can’t I do this?’ The reason is, closure of ileostomy is much easier than a Hartmann reversal, and 90% of these patients get reversed.” In a multicenter trial conducted by Swedish researchers, 62 patients were randomized to Hartmann’s procedure versus primary anastomosis with diverting ileostomy for perforated left-sided diverticulitis (Ann Surg. 2012;256[5]:819-27). The mortality and complications were similar, but the number of patients who got their stoma reversed was significantly less in the Hartmann’s group, compared with the primary anastomosis group (57% vs. 90%, respectively), and the serious complications were much higher in the Hartmann’s group (20% vs. 0). She cited an article from the World Journal of Emergency Surgery as one of the most comprehensive reviews of the subject.
So what is a surgeon to do? For an anastomosis after resection, “consider patient factors: Are they stable?” Dr. Hull said. “What are their comorbid conditions? You have to think, ‘What is my preference? Am I comfortable putting this back together?’ But a primary anastomosis is feasible, even in the acute setting with or without diverting ileostomy. The laparoscopic approach is typically preferred, but if that’s not in your armamentarium, the open [approach] is just fine. You should always perform a leak test. You can also do on table colonic lavage if feasible, especially if you have a large stool burden.”

VIDEO: Researchers beginning to explore microbiome’s effect on surgical outcomes
SAN DIEGO – Surgery seems to stimulate abrupt changes in both the skin and gut microbiome, which in some patients may increase the risk of surgical-site infections and anastomotic leaks. With that knowledge, researchers are exploring the very first steps toward a presurgical microbiome optimization protocol, Heidi Nelson, MD, FACS, said at the annual clinical congress of the American College of Surgeons.
It’s very early in the journey, said Dr. Nelson, the Fred C. Andersen Professor of Surgery at Mayo Clinic, Rochester, Minn. The path is not straightforward because the human microbiome appears to be nearly as individually unique as the human fingerprint, so presurgical protocols might have to be individually tailored to each patient.
Dr. Nelson comoderated a session exploring this topic with John Alverdy, MD, FACS, of the University of Chicago. The panel discussed human and animal studies suggesting that the stress of surgery, when combined with subclinical ischemia and any baseline physiologic stress (chronic illness or radiation, for example), can cause some commensals to begin producing collagenase – a change that endangers even surgically sound anastomoses. The skin microbiome is altered as well, with areas around abdominal incisions beginning to express gut flora, which increase the risk of a surgical-site infection.
Through diet or other presurgical interventions, Dr. Nelson said in a video interview, it might be possible to optimize the microbiome and reduce the chances of some of these occurrences.
She had no financial disclosures.

SAN DIEGO – Surgery seems to stimulate abrupt changes in both the skin and gut microbiome, which in some patients may increase the risk of surgical-site infections and anastomotic leaks. With that knowledge, researchers are exploring the very first steps toward a presurgical microbiome optimization protocol, Heidi Nelson, MD, FACS, said at the annual clinical congress of the American College of Surgeons.
It’s very early in the journey, said Dr. Nelson, the Fred C. Andersen Professor of Surgery at Mayo Clinic, Rochester, Minn. The path is not straightforward because the human microbiome appears to be nearly as individually unique as the human fingerprint, so presurgical protocols might have to be individually tailored to each patient.

RBCs from previously pregnant women linked to increased mortality in men
By contrast, all-cause mortality was not higher in female transplant recipients who received transfusions from previously pregnant females and was not higher in male or female recipients of transfusions from never-pregnant female donors.
The results need to be replicated in prospective trials. “Further research is needed to replicate these findings, determine their clinical significance, and identify the underlying mechanism,” wrote Camila Caram-Deelder, MSc, of the Center for Clinical Transfusion Research, Sanquin Research, Leiden, the Netherlands, and her coauthors (JAMA. 2017;318[15]:1471-78).
The association “may be related to either immunologic phenomena or other mechanisms,” the investigators said. The cause of increased mortality also could be some difference in iron status between the previously pregnant female donors and male donors.
Ms. Caram-Deelder and her associates studied first-time transfusion recipients treated between 2005 and 2015 at six hospitals in the Netherlands. A total of 42,132 patients received 106,641 units of red blood cells. Among this full cohort, 31,118 patients (52% female) received 59,320 units of red blood cells exclusively from one of the three types of donor (88% male, 6% ever-pregnant female, and 6% never-pregnant female) and were followed up for a median of 245 days. During that time, 13% of the cohort died.
For the 14,995 male recipients in the no-donor-mixture cohort, 13% died during follow-up. The hazard ratio for death after 1 additional unit of red blood cells from a never-pregnant female donor, compared with a unit from a male donor, was 0.93 (95% CI, 0.81 to 1.06) for male recipients and 1.01 (95% CI, 0.88 to 1.15) for female recipients. This difference was not significant. Alternatively, for male recipients the HR for death after 1 additional unit of red blood cells from an ever-pregnant female donor, compared with a unit from a male donor, was 1.13 (95% CI, 1.01 to 1.26). The difference was statistically significant (P = .03).
Of the 16,123 female recipients in the no-donor-mixture cohort, 12% died during follow-up. Mortality rates for an ever-pregnant female donor vs. a male donor were 74 and 62 per 1,000 person-years (HR, 0.99; 95% CI, 0.87 to 1.13); for a never-pregnant female donor vs. a male donor, mortality rates were 74 and 62 per 1,000 person-years (HR, 1.01; 95% CI, 0.88-1.15). The difference was not significant.
The highest HRs for death after transfusion of red blood cells from ever-pregnant female donors were observed in male recipients 50 years and younger.
Study funding came from the Dutch Ministry of Health, Welfare and Sports. One investigator in the study reported receiving a speaking fee from Vifor Pharma and serving on the advisory councils of Novartis and Amgen Science.
The provocative finding that men have an increased mortality risk if they receive red blood cell transplants from women with a history of pregnancy could have significant practical implications if proven true in subsequent studies.
Because of the complex methodology of the study, alternative explanations for the association should be considered.
The differences in mortality seem to increase 1 year or more following the transfusion, suggesting that the trigger may be an immunologic mechanism based on maternal immunization to paternal antigens, but until prospective studies confirm that a donor’s sex and pregnancy status are associated with mortality after transplant, “appropriate and conservative use of blood products continues to be the gold standard for safe transfusion.”

GERD postop relapse rates highest in women, older adults
Healthy men younger than 45 years have the lowest risk of relapse after reflux surgery compared with other demographic subgroups, according to data from a population-based study of 2,655 adults in Sweden. The findings were published online in JAMA.
“Cohort studies have shown a high risk of recurrent symptoms of GERD after surgery, which may have contributed to the decline in the use of antireflux surgery,” but long-term reflux recurrence rates and potential risk factors have not been well studied, wrote John Maret-Ouda, MD, and colleagues at the Karolinska Institutet in Stockholm, Sweden.
Overall, 18% of the patients suffered a reflux relapse; 84% of these were prescribed long-term medication, and 16% underwent additional surgery.
The highest relapse rates occurred among women, older patients, and those with comorbid conditions. Reflux occurred in 22% of women vs. 14% of men (hazard ratio 1.57), and the hazard ratio was 1.41 for patients aged 61 years and older compared with those aged 45 years and younger. Patients with one or more comorbidities were approximately one-third more likely to have a recurrence of reflux, compared with those who had no comorbidities (hazard ratio 1.36).
Approximately 4% of patients reported complications; the most common complication was infection (1.1%), followed by bleeding (0.9%), and esophageal perforation (0.9%).
The recurrence rate of 18% is low compared with other studies, the researchers noted. Possible reasons for the difference include the population-based design of the current study, which meant that no patients were lost to follow-up, as well as the recent time period, “in which laparoscopic antireflux surgery has become more centralized to expert centers where selection of patients might be stricter and the quality of surgery might be higher,” they wrote.
The study findings were limited by several factors including clinical variations on coding, lack of data on certain confounding variables including body mass index and smoking, and a lack of control GERD patients who did not undergo antireflux surgery, the researchers said. The results suggest that the benefits of laparoscopic antireflux surgery may be diminished by the potential for recurrent GERD, they added.
The Swedish Research Council funded the study. The researchers had no financial conflicts to disclose.
“The operation can be performed with a relatively low rate of morbidity and a very low mortality rate,” Stuart J. Spechler, MD, wrote in an editorial. “Although findings regarding GERD symptom relief and patient satisfaction based on medication usage data should be interpreted with caution, the observation that more than 80% of patients did not restart antireflux medications after laparoscopic antireflux surgery suggests that the operation provided long-lasting relief of GERD symptoms for most patients,” he said. Although surgery is not a permanent cure for all patients with GERD, “the ever-increasing number of proposed [proton pump inhibitor] risks has caused the greatest concern among clinicians and their patients,” said Dr. Spechler. “Whether the greater than 80% possibility of long-term freedom from PPIs and their associated risks warrants the 4% risk of acute surgical complications and the 17.7% risk of GERD recurrence is a decision that individual patients should make after a detailed discussion of these risks and benefits with their physicians,” he said. However, the study findings suggest “that laparoscopic antireflux surgery might be an especially appealing option for young and otherwise healthy men, who seem to have the lowest rate of GERD recurrence after antireflux surgery and who otherwise would likely require decades of PPI treatment without the operation,” he wrote (JAMA 2017;318:913-5).

POEM found safe, effective for treating achalasia after failed Heller myotomy
Peroral endoscopic myotomy (POEM) safely and effectively treated achalasia in patients with persistent symptoms after Heller myotomy, according to the results of a retrospective study of 180 patients treated at 13 centers worldwide.
Rates of clinical success were 81% among patients who had previously undergone Heller myotomy and 94% among those who had not (P = .01), reported Saowanee Ngamruengphong, MD, of Johns Hopkins Medical Center, Baltimore, with her associates. The groups did not significantly differ in terms of rates of adverse events (8% and 13%, respectively), postprocedural symptomatic reflux (30% and 32%), or reflux esophagitis (44% and 52%). “Although the rate of clinical success in patients with prior Heller myotomy is lower than in those without [it], the safety profile of POEM is comparable,” they wrote in the October issue of Clinical Gastroenterology and Hepatology (doi: 10.1016/j.cgh.2017.01.031).
Heller myotomy achieves a long-term symptomatic response in about 90% of patients with achalasia and has a complication rate of only about 5%, according to Dr. Ngamruengphong and her associates. When this surgery does not successfully resolve symptoms, patients historically have chosen between repeating it or undergoing pneumatic dilation. However, POEM posted high success rates in several small, single-center case series. Thus, the researchers analyzed data on 180 adults with achalasia whose Eckardt scores were at least 3 and who underwent POEM at 13 tertiary care centers in Australia, France, Hong Kong, India, Italy, Japan, the United Kingdom, and the United States during 2009-2015.
POEM was a technical success for 98% for the group of patients who previously had undergone Heller myotomy and for 100% for those who had not, the researchers reported. In the univariate analysis, predictors of clinical failure included prior Heller myotomy (odds ratio, 3.6; 95% confidence interval, 1.3-10.4; P = .02) and prior pneumatic dilation (OR, 2.9; 95% CI, 1.2-7.4; P = .02). In the multivariable analysis, prior Heller myotomy significantly increased the chances of clinical failure (adjusted OR, 3.0; 95% confidence interval, 1.0-8.9; P = .04) after accounting for prior pneumatic dilation and baseline Eckardt score. Prior pneumatic dilation reached borderline significance (adjusted OR, 2.6; 95% CI, 0.99-7.0; P = .05). Clinical failure was not associated with age, sex, achalasia subtypes, previous therapy, baseline Eckardt score, length of myotomy, orientation of myotomy, or extent of lower esophageal sphincter myotomy.
“Previous studies have reported that the success rates of pneumatic dilation in patients who failed prior Heller myotomy ranged between 50% and 89%,” the researchers said. However, success is often short-lived, with up to 45% of patients needing another procedure within 2 years, putting them at risk of “potentially serious adverse events, such as esophageal perforation or aspiration,” they added.
Repeat surgical myotomy is reportedly successful in 73%-89% of cases; however, itis technically challenging because of adhesions and fibrosis from the previous surgery and is associated with a high risk of gastrointestinal perforation.
Clinicians should carefully investigate the reasons a Heller myotomy failed in order to elect a course of action, the researchers emphasized. “For instance, for patients with symptom relapse or failure to respond to surgical myotomy as a result of incomplete myotomy or myotomy fibrosis, POEM is likely to be effective,” they said. “On the other hand, when the cause of persistent symptoms after surgical myotomy is tight fundoplication, a redo fundoplication should be recommended.”

Repeat surgical myotomy is reportedly successful in 73%-89% of cases; however, itis technically challenging because of adhesions and fibrosis from the previous surgery and is associated with a high risk of gastrointestinal perforation.
Clinicians should carefully investigate the reasons a Heller myotomy failed in order to elect a course of action, the researchers emphasized. “For instance, for patients with symptom relapse or failure to respond to surgical myotomy as a result of incomplete myotomy or myotomy fibrosis, POEM is likely to be effective,” they said. “On the other hand, when the cause of persistent symptoms after surgical myotomy is tight fundoplication, a redo fundoplication should be recommended.”

Peroral endoscopic myotomy (POEM) safely and effectively treated achalasia in patients with persistent symptoms after Heller myotomy, according to the results of a retrospective study of 180 patients treated at 13 centers worldwide.
Rates of clinical success were 81% among patients who had previously undergone Heller myotomy and 94% among those who had not (P = .01), reported Saowanee Ngamruengphong, MD, of Johns Hopkins Medical Center, Baltimore, with her associates. The groups did not significantly differ in terms of rates of adverse events (8% and 13%, respectively), postprocedural symptomatic reflux (30% and 32%), or reflux esophagitis (44% and 52%). “Although the rate of clinical success in patients with prior Heller myotomy is lower than in those without [it], the safety profile of POEM is comparable,” they wrote in the October issue of Clinical Gastroenterology and Hepatology (doi: 10.1016/j.cgh.2017.01.031).
Heller myotomy achieves a long-term symptomatic response in about 90% of patients with achalasia and has a complication rate of only about 5%, according to Dr. Ngamruengphong and her associates. When this surgery does not successfully resolve symptoms, patients historically have chosen between repeating it or undergoing pneumatic dilation. However, POEM posted high success rates in several small, single-center case series. Thus, the researchers analyzed data on 180 adults with achalasia whose Eckardt scores were at least 3 and who underwent POEM at 13 tertiary care centers in Australia, France, Hong Kong, India, Italy, Japan, the United Kingdom, and the United States during 2009-2015.
POEM was a technical success for 98% for the group of patients who previously had undergone Heller myotomy and for 100% for those who had not, the researchers reported. In the univariate analysis, predictors of clinical failure included prior Heller myotomy (odds ratio, 3.6; 95% confidence interval, 1.3-10.4; P = .02) and prior pneumatic dilation (OR, 2.9; 95% CI, 1.2-7.4; P = .02). In the multivariable analysis, prior Heller myotomy significantly increased the chances of clinical failure (adjusted OR, 3.0; 95% confidence interval, 1.0-8.9; P = .04) after accounting for prior pneumatic dilation and baseline Eckardt score. Prior pneumatic dilation reached borderline significance (adjusted OR, 2.6; 95% CI, 0.99-7.0; P = .05). Clinical failure was not associated with age, sex, achalasia subtypes, previous therapy, baseline Eckardt score, length of myotomy, orientation of myotomy, or extent of lower esophageal sphincter myotomy.
“Previous studies have reported that the success rates of pneumatic dilation in patients who failed prior Heller myotomy ranged between 50% and 89%,” the researchers said. However, success is often short-lived, with up to 45% of patients needing another procedure within 2 years, putting them at risk of “potentially serious adverse events, such as esophageal perforation or aspiration,” they added.

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY
Key clinical point:
Major finding: Rates of clinical success were 81% when patients had previously undergone Heller myotomy and 94% when they had not (P = .01). Rates of adverse events (8% and 13%, respectively), as well as rates of postprocedural symptomatic reflux (30% and 32%) and reflux esophagitis (44% and 52%), were similar between groups.
Data source: A multicenter retrospective study of 180 patients with achalasia, half of whom had symptoms despite prior Heller myotomy.
Disclosures: Dr. Ngamruengphong had no disclosures. Three coinvestigators disclosed consulting relationships with Boston Scientific, Medtronic, Sandhill Scientific, Erbe, and Cosmo Pharmaceuticals.
ACS NSQIP pilot project IDs risks in older surgical patients
NEW YORK – The American College of Surgeons’ National Surgical Improvement Program Geriatric Surgery Pilot Project, which was initiated in 2014, is beginning to bear fruit.
Institutions participating in the project are generating data on geriatric-specific factors such as cognition and mobility that have been shown to add to standard risks associated with surgery in older adults.
“Before you operate at all, there is a decision, and often surgeons use this framework when deciding whether or not to operate: There is an isolated surgical problem, and I think we can fix that problem,” Julia R. Berian, MD, said at the ACS Quality and Safety Conference. “This fails to really incorporate the context of these older, complicated surgical patients.”
“We are facing a silver tsunami. The population is aging,” Emily Finlayson, MD, FACS, said during a separate presentation at the conference. “People are coming to us to decide, A, if they should have surgery, and B, how best to prepare for surgery.”
“As we know, from mounting evidence, surgical outcomes in frail older adults are pretty abysmal.” In addition to the physiologic vulnerabilities, “there is a lot of social isolation, depression, and anxiety that is underdiagnosed in this population,” Dr. Finlayson said. “In light of these incredibly high risks, we need to approach decision making in a slightly different way than we do with, say, a 40-year-old patient.”
Use data to guide interventions
The ACS NSQIP and the ACS Geriatric Task Force created the ACS NSQIP Geriatric Surgery Pilot Project in part to determine if including geriatric-specific preoperative variables and outcome measures in the NSQIP database would improve postoperative outcomes. Since its launch in January 2014, more than 30 hospitals have contributed data from over 30,000 surgical cases involving patients 65 years and older. The vast majority of cases involve orthopedic surgery or general surgery, with total hip and total knee arthroplasty, colectomy, spine surgery, and hip fracture procedures leading the list.
Cognition, function, mobility, and goals/decision making are the four main project domains. “The event rate for postoperative delirium overall was 12%; the functional decline was quite high at 43%; and the need for postoperative mobility aid was 30%,” said Dr. Berian, a fourth-year general surgery resident at the University of Chicago and an ACS Clinical Scholar, when presenting initial 3-year results.
“What we have learned from this experience is that these geriatric-specific risk factors do contribute to risk adjustment for traditional morbidity and mortality outcomes. In other words, we think they are very important to collect,” Dr. Berian said.
Cognitive impairment was associated only with prolonged ventilation, whereas surrogate consent for surgery correlated with any morbidity, reintubation, pneumonia, and more. Use of a mobility aid before surgery correlated with increased risk for a UTI, surgical site infection, sepsis, and other morbidities. A history of falls within the previous year was associated with higher risk of cardiac complications and mortality. Functional status, origin from home before surgery, and use of preoperative palliative care were not contributors to risk.
A second objective of the project is to create a platform for introducing interventions to improve outcomes in this population. Future plans include further validation of the pilot data and incorporation of the results into a geriatric-specific quality program.
Focus on potential solutions
Addressing a wide range of preoperative considerations in older adults may seem daunting, but “there are simple, low-tech things you can do,” said Dr. Finlayson, director of the University of California San Francisco Center for Surgery in Older Adults. Strategies include reviewing medications, providing adequate hydration “so they don’t come in as dry as a potato chip,” and removing earwax. “You might think they’re confused but they really cannot hear.”
Whenever possible, address the core vulnerabilities that put an older patient at higher risk, Dr. Finlayson said. Comorbidity, polypharmacy, incontinence, social isolation, depression and anxiety, as well as deficits in function, nutrition, and mobility can contribute.
Cognition is also critical. If you think an older patient is at risk of postoperative delirium, involve the family, Dr. Finlayson recommended. “We know if family members are at the bedside, the patient is less likely to get confused.” Clinicians at UCSF found this “very helpful” and even give families a sign-up sheet to assign shifts in the hospital.
“If you don’t think delirium is an important outcome to begin tracking in our registries, I want to point out that there are serious consequences for postop delirium,” Dr. Berian said. Delirium alone in surgical patients doubles the increased risk of prolonged length of stay, 1.5 times the risk for institutional discharge, and 2.3 times the risk for 30-day readmission (JAMA Surgery. 2015;150[12]:1134-40). “When you combine delirium with complications, those risks increase dramatically,” she added.
Take a team approach
Session moderator David A. Hoyt, MD, FACS, executive director of the American College of Surgeons, asked Dr. Finlayson how she convinced her colleagues to participate in the program at UCSF.
“We haven’t had any problems with buy-in in terms of recognizing the need,” she replied. “The challenge is a lot of surgeons feel like they don’t have the expertise or the time to slow down and learn how to do these assessments and optimization strategies.” She suggested involving geriatricians and other providers when possible. “You have to be very creative within your own system in terms of what kind of team you are going to put together.”
Elicit patient goals
Perhaps most importantly, you really need to individualize your approach, Dr. Finlayson said. Take the time to talk to these patients. “This isn’t just don’t smoke, lose weight, diet and exercise. It’s eliciting patient goals and tailoring an assessment of geriatric vulnerability,” she added. “It’s not one size fits all. It’s not just about fitness for surgery; it’s about what they want for the rest of their lives.”
Patient-driven goals are important, Dr. Berian said, because “older adults may prioritize quality of life over quantity of life.” She also noted that surgery could cure their disease, prolong life, and/or provide symptom relief, or it could cause loss of function and independence, delirium, cognitive loss, and/or premature death. “There was an interesting study … looking at outcomes that could be considered worse than death,” Dr. Berian said (JAMA Intern. Med. 2016;176[10]:1557-9). Bowel and bladder incontinence, being confused all the time, and relying on a feeding tube to live were among the outcomes the researchers examined.
Dr. Finlayson highlighted a high-touch, resource-intensive, and successful intervention in older patients in the United Kingdom (Age Ageing. 2007;36[6]:670-5). “The reduction in morbidity was incredibly dramatic.” The study shows if you truly have the resources to address these geriatric syndromes, you can really improve care in this population.
