Antibiotic exposure blunted metabolic improvement following vertical sleeve gastrectomy
SAN DIEGO – results from a mouse study demonstrated.
The finding raises the question of whether patients with suboptimal outcomes following vertical sleeve gastrectomy may benefit from microbial modulation.
“More work is needed to clarify the role of the microbiome as it pertains to bariatric surgery,” lead study author Cyrus Jahansouz, MD, said in an interview in advance of the annual clinical congress of the American College of Surgeons. “However, it appears that factors that alter the gut microbial composition following surgery, such as antibiotics, can potentially lead to failure of metabolic improvement following surgery.”
According to Dr. Jahansouz of the University of Minnesota Microbiota Transplantation Program, mechanisms mediating metabolic improvement following bariatric surgery remain incompletely understood. “Outcomes are also somewhat variable: As many as 40%-75% of patients regain weight in the years following nadir of weight loss,” he said. “Human studies have shown an acute and sustained shift in the gut microbiota, and an altered bile acid profile. Bile acids increase following surgery.”
Meanwhile, mice deficient in Farnesoid X-receptor (FXR) and Takeda G protein–coupled Receptor 5 (TGR5) do not experience metabolic improvement following bariatric surgery; the composition of the microbiome can significantly impact the composition of bile acids.
“By altering the postsurgical composition of mice following bariatric surgery, we eliminate the metabolic benefits of surgery, possibly by altering bile acid profiles,” Dr. Jahansouz said.
For the trial, diet-induced obese mice were randomized to vertical sleeve gastrectomy (VSG) or sham surgery, with or without exposure to antibiotics that selectively suppress mainly gram-positive (fidaxomicin, streptomycin) or gram-negative (ceftriaxone) bacteria on postoperative days 1-4. The researchers characterized fecal microbiota before surgery and on postoperative days 7 and 28. Mice were metabolically characterized on postoperative days 30-32 and euthanized on postoperative day 35.
Mice in the VSG group experienced weight loss and shifts in the intestinal microbiota composition, compared with those in the sham surgery group.
“Antibiotic exposure resulted in sustained reductions in alpha (within sample) diversity of microbiota and shifts in its composition,” the researchers wrote in their abstract. “Different antimicrobial specificity of antibiotics led to functionally distinct physiologic effects. Specifically, fidaxomicin and streptomycin markedly altered hepatic bile acid signaling and lipid metabolism, while ceftriaxone resulted in greater reduction in the expression of key antimicrobial peptides.
“However, VSG mice exposed to antibiotics, regardless of their specificity, had significantly increased subcutaneous adiposity and impaired glucose homeostasis without changes in food intake, relative to control mice,” the investigators noted.
Dr. Jahansouz said that he was surprised by the fact that all three antibiotics tested, no matter their specificity in gut bacteria eliminated, resulted in significantly diminished weight loss and metabolic improvement following vertical sleeve gastrectomy in the mouse model. He acknowledged that translating the findings from mice to humans is a key limitation of the analysis.
“There are fundamental physiologic differences between mice and humans that need consideration in all murine models of metabolic disorders,” he said. “Therefore, it is critical that insights gained from these models are followed up in human studies.”
The study was funded by the American Diabetes Association and a Minnesota Discovery, Research and InnoVation Economy grant from the University of Minnesota. Dr. Jahansouz reported having no financial disclosures.

Low risk of bariatric surgery complications in IBD
Bariatric surgery is safe and feasible in patients with inflammatory bowel disease (IBD), with a low risk of postoperative complications vs. controls, according to results of a recent cohort study.
Besides a significantly higher risk of perioperative small-bowel obstruction and a 1-day increase in hospital stay, outcomes were comparable between patients with IBD and controls (Obes Surg. 2017 Oct 10. doi: 10.1007/s11695-017-2955-4).
Limitations of the retrospective study, according to the authors, included a potential underestimation of short-term postoperative complications, since the data set used in the study was limited to in-hospital stays and would not include events occurring after discharge.
Nevertheless, “our data show that it is reasonable to carefully proceed with bariatric interventions in obese IBD patients, especially those who are at higher risk of cardiovascular mortality and drastic need for weight reduction, to accrue benefits of weight loss,” wrote Fateh Bazerbachi, MD, of the Mayo Clinic, Rochester, Minn. and his coauthors.
Bariatric surgery is the “most effective solution” for obesity, and “appropriate candidates should not be deprived of this important, potentially life-saving procedure, if the intervention is deemed acceptably safe,” Dr. Bazerbachi and his colleagues noted.
Their cohort study included data for 314,864 adult patients in the Nationwide Inpatient Sample who underwent bariatric surgery between 2011 and 2013. Of that group, 790 patients had underlying IBD (459 Crohn’s disease, 331 ulcerative colitis). Remaining patients made up the comparator group.
The primary outcomes evaluated in the study included risks of systemic and technical complications. Risk of perioperative small-bowel obstruction was significantly higher in the IBD group (adjusted odds ratio, 4.0; 95% confidence interval, 2.2-7.4). However, the rates of other complications were similar between the two groups, data show.
Secondary outcomes in the study included length of hospital stay and mortality. Mean length of hospital stay was 3.4 days for IBD patients, vs. 2.5 days for the comparison group (P = .01), according to the report. Mortality was 0.25% for controls, while no deaths were reported in the IBD group.
In the future, bariatric surgeons may face increasing demand to treat IBD patients, given the increasing prevalence of obesity in the IBD patient population, Dr. Bazerbachi and his colleagues said.
Some surgeons may believe that bariatric intervention is more challenging in IBD patients, in part because of the underlying inflammatory state that might interfere with healing of wounds and recovery of bowel motility, they said. Bariatric surgery, however, can reduce body mass index, which in turn might make future IBD surgeries less challenging.
Another potential advantage is reduction in cardiovascular risk, which is elevated in IBD patients both due to obesity as well as the IBD condition, they added.
“Further studies are certainly needed to examine long-term outcomes of bariatric surgery on IBD and to determine whether cardiovascular mortality is reduced from these interventions in this susceptible cohort of obese IBD patients,” Dr. Bazerbachi and his colleagues wrote.
The authors declared that they had no conflicts of interest.

Many women have unprotected sex in year after bariatric surgery
More than 40% of reproductive-age women reported having unprotected sex in the year after undergoing bariatric surgery, despite recommendations to avoid pregnancy for at least a year, a new study finds. Another 4% of women reported trying to conceive in the 12 months after surgery.
“We were surprised to find such a large percentage of women were not using contraception, and we were also surprised to find so many were actively trying to conceive,” the study’s lead author Marie N. Menke, MD, MPH, of the University of Pittsburgh, said in an interview. “Reproductive-age women who are considering bariatric surgery should be counseled that they should plan to use contraceptives after surgery for about 12-18 months.”
Pregnancy isn’t recommended over that period mainly because of the risks to the fetus, Dr. Menke said. “These risks are different from obesity in general. We don’t know exactly why surgery causes these risks, but ideally, patients would be weight-stable prior to conception.”
In 2013, the American Association of Clinical Endocrinologists, the Obesity Society, and the American Society for Metabolic & Bariatric Surgery provided a Grade D recommendation for a 12-18 month delay in conception (Obesity [Silver Spring] 2013;21[suppl 1]:S1-27). A recent study provided more insight into the potential risks of pregnancy soon after weight-loss procedures. It reported that, compared with those who gave birth more than 4 years later, women who gave birth within 2 years of bariatric surgery had higher risks of premature birth, admission to neonatal intensive care units, and small-for-gestational-age infants (JAMA Surg. 2017 Feb 1;152[2]:1-8).
The current prospective cohort study included women who underwent bariatric surgery for the first time during 2005-2009 at 10 U.S. hospitals. The women, all aged 18-44 years, answered questions for as long as 7 years, until January 2015 (Obstet Gynecol. 2017 Oct 6. doi: 10.1097/AOG.0000000000002323).
The analysis included 710 women who provided conception data. The median body mass index of the women was 46.3 kg/m2. Most patients underwent Roux-en-Y gastric bypass (73%), followed by laparoscopic adjustable gastric banding (23%).
Researchers found that 4.3% of the women tried to conceive in the first year after surgery (95% confidence interval, 2.4-6.3), and 13.1% did so in the second year (95% CI, 9.3-17.0; P less than .001).
During the first year after surgery, 12.7% of women had no intercourse (95% CI, 9.4-16.0), 40.5% had only protected intercourse (95% CI, 35.6-45.4), and 41.5% (95% CI, 36.4-46.6) had unprotected intercourse while not trying to conceive.
Why are the unprotected sex numbers so high? “We wonder if some women simply feel that they cannot get pregnant,” Dr. Menke said. “Our group has previously reported that 42% of women who had attempted to conceive prior to bariatric surgery had a history of infertility. Some of these women went on to deliver a live birth, but many did not.”
The study reports that 183 of the 710 women did ultimately conceive and that the number may be as high as 237 because data were missing for 54 women who may have not wanted to report a nonlive birth. Of the women who reported conceiving, 68.9% had live births, 1.1% had stillbirths, 1.1% had ectopic pregnancies, 21.9% miscarried and 7.1% had abortions.
“We’d really like this research to be a reason to consider presurgical contraceptive counseling as one of the steps prior to bariatric surgery,” Dr. Menke said. “This may include a referral by the bariatric surgeon to a physician would who provide counseling, prescribe, or both.”
The study was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Menke reported having no relevant disclosures. Her coauthors reported financial relationships with pharmaceutical and medical device companies with products to treat metabolic diseases.

Swedish study finds low risk of developing psoriasis in bariatric surgery patients
Obese patients who undergo bariatric surgery have a lower risk of later developing psoriasis, according to results of nonrandomized, longitudinal intervention trial.
Cristina Maglio, MD, of the University of Gothenburg, Sweden, and her associates found that over a 26-year follow-up period, the adjusted hazard ratio (HR) of developing psoriasis was 0.65 (95% confidence interval [CI], 0.47-0.89; P = .008) for patients who underwent bariatric surgery, compared with those who received conventional, nonsurgical obesity treatments. Psoriasis developed in 3.6% of 1,991 patients in the surgery group during follow-up and in 5.1% of 2,018 control patients during follow-up.
Conversely, the difference in the risk of developing psoriatic arthritis (PsA), experienced by up to one-third of patients with psoriasis, was not statistically significant (HR, 0.77; 95% CI, 0.43-1.37; P = .287). PsA developed in 1% of subjects from the surgery group and 1.3% from the control group.
To understand how surgery affected the development of psoriasis or psoriatic arthritis, the researchers conducted a trial with a control group and surgery group. In the control group, 2,018 patients received standard obesity treatments that included recommendations on eating behavior, food selection, and physical activity. The 1,991 patients in the surgery group underwent gastric banding (375), vertical banded gastroplasty (1,354), or gastric bypass (262). At the start of the study, patients were evaluated for baseline measurements, then again at 6 months. After the 6-month mark, patients were reevaluated at 1, 2, 3, 4, 6, 8, 10, 15, and 20 years, respectively. All study participants, regardless of trial group, were examined and presented patient health questionnaires at each follow-up. The endpoint for this study was the first diagnosis of either psoriasis or PsA. Body mass index decreased significantly in the surgery group, compared with virtually no change in the control group.
Vertical banded gastroplasty was found to significantly lower the incidence of psoriasis, compared with usual treatment. But using gastric banding as a reference, vertical banded gastroplasty (HR, 0.80; 95% CI, 0.46-1.39; P = .418) and gastric bypass (HR, 0.71; 95% CI, 0.29-1.71; P = 0.439) were found to have similar effects on the prevention of psoriasis.
The researchers also identified several risk factors that significantly increased the risk of developing psoriasis. Smoking (HR, 1.75; 95% CI, 1.26-2.42; P = .001), a known risk factor in the development of psoriasis, and the length of time a patient had been obese (HR, 1.28; 95% CI, 1.05-1.55; P = .014) were found to be independently associated with an increased risk of psoriasis.
As part of their risk analysis, Dr. Maglio and her colleagues analyzed the interactions of baseline risk factors such as BMI and obesity duration with the bariatric surgery. This analysis found no significant interactions between baseline risk factors and bariatric surgery. It did reveal that patients who were older at baseline evaluation had slightly better responses to bariatric surgery with lower incidences of psoriasis, compared with younger patients, but the differences were not statistically significant.
“The preventive role of bariatric surgery on the risk of psoriasis has been recently highlighted by a retrospective Danish study (JAMA Surg. 2017 Apr 1;152[4]:344-9),” noted Dr. Maglio and her colleagues. “However, we lent strength to the previous results by confirming this association in a large prospective intervention trial designed to examine the effect of bariatric surgery on obesity-related comorbidities in comparison with usual obesity care.

Long-term specialist care reduces post-RYGB anemia risk
Patients who underwent Roux-en-Y gastric bypass surgery (RYGB) without long-term bariatric specialist follow-up experienced a significantly higher rate of anemia at 10 years than did patients who had such specialist follow-up, according to findings from a database review.
Among 74 patients available for analysis – 58 men and 16 women with a mean age of 51 years who underwent RYGB at a single Veterans Affairs medical center between 2002 and 2006 – the mean rate of preoperative anemia was 20% (15 patients). The rate increased to 28% (21 patients) at 1 year, 31% (23 patients) at 5 years, and 47% (35 patients) at 10 years, according to a research letter by Gao Linda Chen, MD, and her colleagues in the surgical service of the VA Palo Alto (Calif.) Health Care System (JAMA Surg. 2017. Sep 20. doi: 10.1001/jamasurg.2017.3158).
Among 58 patients with no bariatric specialist follow-up after 5 years, the anemia rate increased from 22% (13 patients) before surgery to 57% (33 patients) at 10 years, while the corresponding rates for those with specialty follow-up were 19% (3 patients) and 13% (2 patients). After adjustment for preoperative anemia, those without specialist follow-up had significantly higher odds of anemia at 10 years (odds ratio, 6.1).
“Long-term complications of RYGB, such as anemia, may go unrecognized by nonbariatric specialists,” the investigators wrote, noting that the high rates of anemia at 10 years “may reflect a mixed vitamin and mineral deficiency, because patients had normocytic anemia.
“Our study suggests that follow-up with bariatric specialists more than 5 years after surgery, rather than with specialists with no bariatric expertise, can decrease long-term anemia risk,” they continued. “This finding may demonstrate the bariatric specialist’s specific understanding of the long-term risk for nutritional deficiency after RYGB and the importance of vitamin and mineral supplementation.”
The findings suggest a bariatric team approach with planning for long-term follow-up. “We implemented a hub-and-spoke model for bariatric care, including health care specialist education, in which the bariatric team communicates regularly with the patient’s primary care clinician before and after surgery.”
Although the study is limited by small sample size, the findings nevertheless underscore that “long-term follow-up should be an integral part of bariatric programs, and additional studies are needed to identify potential barriers to successful follow-up,” they concluded.

Diagnostic laparoscopy pinpoints postop abdominal pain in bariatric patients
The etiology of chronic pain after bariatric surgery can be difficult to pinpoint, but diagnostic laparoscopy can detect causes in about half of patients, findings from a small study have shown.
In an investigation conducted by Mohammed Alsulaimy, MD, a surgeon at the Bariatric and Metabolic Institute at the Cleveland Clinic, and his colleagues, 35 patients underwent diagnostic laparoscopy (DL) to identify the causes of their chronic abdominal pain after bariatric surgery. Patients included in the study had a history of abdominal pain lasting longer than 30 days after their bariatric procedure, a negative CT scan of their abdomen and pelvis, a gallstone-negative abdominal ultrasound, and an upper GI endoscopy with no abnormalities. Researchers collected patient data including age, gender, body, weight, and body mass index, type of previous bariatric procedure, and time between surgery and onset of pain.
The results of DL were either positive (presence detected of pathology or injury) or negative (no disease or injury detected).
Twenty patients (57%) had positive findings on DL including the presence of adhesions, chronic cholecystitis, mesenteric defect, internal hernia, and necrotic omentum, and of this group, 43% had treatment that led to improvement of pain symptoms. Only 1 of the 15 patients with negative DL findings had eventual improvement of their pain symptoms. Most patients with negative DL findings had persistent abdominal pain, possibly because of nonorganic causes and were referred to the chronic pain management service, the investigators wrote.
“About 40% of patients who undergo DL and 70% of patients with positive findings on DL experience significant symptom improvement,” the investigators said. “This study highlights the importance of offering DL as both a diagnostic and therapeutic tool in post–bariatric surgery patients with chronic abdominal of unknown etiology.”
The investigators had no relevant financial disclosures to report.

Roux-en-Y gastric bypass produced durable clinical improvements at 12 years
Severely obese individuals in the United States who underwent Roux-en-Y gastric bypass (RYGB) averaged a 27% weight loss 12 years later, with only a 3% incidence of type 2 diabetes mellitus and a 51% rate of diabetes remission, according to the results of a large multicenter observational prospective study.
In striking contrast, patients who did not undergo bariatric surgery averaged a 1%-2% weight loss at 12 years, a 26% incidence of diabetes, and only a 5%-10% rate of diabetes remission, said Ted D. Adams, PhD, of the University of Utah, Salt Lake City, and his associates. RYGB surgery also conferred substantial and statistically significant improvements long-term improvements in systolic hypertension and lipid levels, the researchers reported in the New England Journal of Medicine (2017 Sep 20. doi: 10.1056/NEJMoa1700459).
Few prospective studies have tracked long-term outcomes after bariatric surgery. Among 1,156 participants in this study, 418 patients underwent RYGB, 417 individuals sought but did not undergo surgery – mainly for insurance reasons – and 321 individuals did not seek surgery. Participants were mostly females in their 40s or 50s at baseline, and typically weighed 120 kg-130 kg.
“The follow-up rate exceeded 90% at 12 years,” the researchers wrote. Two years after undergoing Roux-en-Y gastric bypass, patients had lost an average of 45 kg (95% confidence interval, 43-47 kg). By postoperative year 6, they had regained an average of 9 kg (average loss from baseline, 36 kg; 95% CI, 34-39 kg). But they typically gained only about 1.3 kg more between years 6 and 12, and they had about a 92% lower odds of developing diabetes mellitus, compared with individuals who did not undergo bariatric surgery (odds ratio, 0.08; P less than .001). “Remission of type 2 diabetes was much more likely if the Roux-en-Y gastric bypass occurred before [patients began] treatment with insulin, presumably owing to the ability of partially viable beta cells to improve their function,” the researchers noted.
Funders included the National Institute of Diabetes and Digestive and Kidney Diseases, the National Center for Research Resources, Weill Cornell Medicine, and Intermountain Healthcare. Dr. Adams reported having no relevant conflicts of interest. One coinvestigator disclosed royalties from licensing a questionnaire on weight loss and quality of life, and another coinvestigator disclosed fees for services rendered during a trial of an intragastric balloon. The remaining researchers had no relevant disclosures.

In striking contrast, patients who did not undergo bariatric surgery averaged a 1%-2% weight loss at 12 years, a 26% incidence of diabetes, and only a 5%-10% rate of diabetes remission, said Ted D. Adams, PhD, of the University of Utah, Salt Lake City, and his associates. RYGB surgery also conferred substantial and statistically significant improvements long-term improvements in systolic hypertension and lipid levels, the researchers reported in the New England Journal of Medicine (2017 Sep 20. doi: 10.1056/NEJMoa1700459).
Few prospective studies have tracked long-term outcomes after bariatric surgery. Among 1,156 participants in this study, 418 patients underwent RYGB, 417 individuals sought but did not undergo surgery – mainly for insurance reasons – and 321 individuals did not seek surgery. Participants were mostly females in their 40s or 50s at baseline, and typically weighed 120 kg-130 kg.
“The follow-up rate exceeded 90% at 12 years,” the researchers wrote. Two years after undergoing Roux-en-Y gastric bypass, patients had lost an average of 45 kg (95% confidence interval, 43-47 kg). By postoperative year 6, they had regained an average of 9 kg (average loss from baseline, 36 kg; 95% CI, 34-39 kg). But they typically gained only about 1.3 kg more between years 6 and 12, and they had about a 92% lower odds of developing diabetes mellitus, compared with individuals who did not undergo bariatric surgery (odds ratio, 0.08; P less than .001). “Remission of type 2 diabetes was much more likely if the Roux-en-Y gastric bypass occurred before [patients began] treatment with insulin, presumably owing to the ability of partially viable beta cells to improve their function,” the researchers noted.

Immobility implicated in increased complications after bariatric surgery
NEW YORK –
“The importance of this study is to help us as an institution, but then also nationally, to try to focus on quality initiatives to improve the complication rate and safety profile of these patients, who are incredibly high risk for bariatric surgery,” said Rana Higgins, MD, a general surgeon at Froedtert Hospital and the Medical College of Wisconsin in Milwaukee.
Dr. Higgins and her colleagues compared 2,969 immobile patients with 145,741 who were ambulatory before surgery. The most common bariatric procedure was sleeve gastrectomy at 56%. Another 30% had gastric bypass, 3% had the gastric band, and the remaining 1% underwent other procedures, such as biliopancreatic diversion with duodenal switch. The MBSAQIP (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program) defines immobility as a patient with limited ambulation who requires assistive devices, such as a scooter or wheelchair, to ambulate most or all of the time. In addition, with regard to negotiating stairs, immobile patients need a home lift or an elevator.
“What we found in fact is that nearly every postoperative complication was significantly increased in the immobile patients,” Dr. Higgins said at the American College of Surgeons Quality and Safety Conference. These patients were significantly more likely to experience renal failure (odds ratio, 6.4), wound disruption (OR, 4.5), unplanned intubation (OR, 4.3), and sepsis (OR, 4.3). “Almost every complication had an odds ratio over 2 in the immobile population, and all of these were statistically significant,” she added.
Only three complications evaluated by the researchers were not statistically different between groups: intraoperative or postoperative coma, stroke, and myocardial infarction.
Operative time was longer in the immobile group, about 102 minutes vs. 91 minutes (P less than .001). A meeting attendee asked what accounted for the difference. Dr. Higgins replied, “We’ll have to go back and look at our data. My hypothesis is that the immobile patients had a higher BMI [body mass index]. They may also have had other comorbidities that contributed to increased operative time.”
Hospital length of stay was also significantly longer among immobile patients at 2.3 days vs. 1.8 days in the ambulatory group (P less than .001).
The readmission rate was higher among immobile patients – 7.3% vs. 4.3% for the ambulatory group. The reoperation rate was higher at 2.6% vs. 1.4%. Both these findings were statistically significant as well (P less than .001).
Immobile patients had a statistically higher risk of mortality at 0.5%, compared with 0.1% among ambulatory patients (OR, 4.6).
A meeting attendee asked Dr. Higgins if her institution addresses mobility issues. She replied that there is preoperative education about the importance of ambulation, but the interventions are focused on ambulation in the postoperative period. “We order physical therapy, immediately postoperatively; typically the patients will receive it that day or the next day. We make sure patients are up and moving as much as possible, but there are limitations if they have limited mobility.”
The same attendee suggested preoperative physical therapy could help, even if only 2-4 weeks prior to surgery. Dr. Higgins agreed that would be a good quality initiative to explore in the future.
She had no relevant financial disclosures.

Think beyond BMI to optimize bariatric patients presurgery
NEW YORK – A structured, four-pronged approach to get patients as fit and healthy as possible prior to bariatric surgery holds the potential to improve postoperative outcomes. In general, bariatric surgery patients are in a better position than most surgery candidates because of a longer preoperative period. During this time, surgeons can work with a multidisciplinary team to optimize any medical, nutritional, exercise-related, and mental health concerns.
“We have a unique window of opportunity. There is some emergent bariatric surgery, but the bulk is going to be scheduled, elective surgery. We typically have a longer lead time in many cases, and that has to do with insurance requirements and hoops we have to jump through,” said Teresa L. LaMasters, MD, FACS, medical director of bariatric surgery at UnityPoint Clinic Weight Loss in West Des Moines, Iowa.
“People focus on the size of our patients and the weight of our patients, but [body mass index] is only one factor. They can have many other comorbidities that are significant,” Dr. LaMasters said. Patients can present with cardiac and pulmonary issues, hypertension, sleep apnea, diabetes, asthma, reflux and “a very high incidence of anxiety and depression.”
“So we have a lot of challenges,” she added. “We take care of complex, high-risk patients, and our goal is to improve outcomes. Using presurgery optimization can be a key to that.”
Maximizing medical readiness
Multiple providers drive the medical intervention, Dr. LaMasters said, including surgeons and primary care doctors, as well as advanced practice providers, medical weight loss providers, and other specialists. “We do try to get patients to lose weight before surgery, but that’s not an absolute requirement. More important is adjustment of other risk factors like pulmonary risk factors, control of hypertension, treatment of sleep apnea, and control of hyperglycemia. We’d like to have their A1c [test results to be] under 8%. We want to start [proton pump inhibitors] early because there is a very high prevalence of reflux and gastritis in this population.”
Bariatric surgery patients “are uniquely positioned to have a substantial benefit from that ‘prehabilitation,’ but this only works if you have a multidisciplinary team,” Dr. LaMasters said at the American College of Surgeons Quality and Safety Conference. “Think of this as down-staging disease, like in a cancer model.”
“The message from this is there is an opportunity if we build it into the prehab phase of care. It’s a new way of thinking in surgery. You can change your results,” said session moderator David B. Hoyt, MD, FACS, Executive Director of the American College of Surgeons.
Nutritional know-how
Dietitians determine the second component – how to optimize nutrition before surgery. They focus on education, evaluation, setting goals, “and very importantly, supporting patients to attain those goals,” Dr. LaMasters said. Goals include increasing protein intake prior to surgery to a recommended 1.5 g/kg/day and starting nutritional supplements ahead of time.
Even though they typically consume an excess amount of calories, “many of our patients have baseline malnutrition,” Dr. LaMasters said. Establishing mindful behavior for meal planning, preparation, and eating is a potential solution, as is addressing any socioeconomic factors that can present challenges to healthy eating.
Emphasizing exercise
“The exercise piece is really key for our patients,” Dr. LaMasters said. Many candidates for bariatric surgery have mobility issues. “The first thing many say is ‘I can’t exercise.’ We instruct them that they can exercise. Our job is to find out what they can do – there are many different exercise modalities.”
A good baseline assessment is a 6-minute walk test to assess their distance limits, oxygen level, and any resulting symptoms.
“Our goal is to get them to walking – even those who can barely walk with a walker – for 5-10 minutes, six times a day,” Dr. LaMasters said. “We feel that is a minimum threshold to prevent blood clots after surgery.” Another recommendation is to get surgical candidates to do some activity 30 minutes a day, four times a week, at a minimum. “Eventually, after surgery and when they’ve lost weight and are healthier, the goal is going to be 1 hour, five days a week.”
Start the exercise program at least 4-8 weeks prior to surgery. Most studies show significant benefit if you start at least 4 weeks prior to surgery, Dr. LaMasters suggested. “In our own practice, we’ve seen if you can start a daily walking program even just 2 weeks prior to surgery, we see a significant benefit.”
Addressing anxiety or depression
The mental health piece is very important and should be guided by mental health providers on the multidisciplinary team, Dr. LaMasters said.
“Our patients have a high degree of stress in their lives, especially related to socioeconomic factors. A patient who does not have their anxiety or depression under control will not do as well after surgery.”
Optimization in other specialties
The benefits of a prehabilitation exercise program have been demonstrated across many other specialties, especially in colorectal surgery, cardiovascular surgery, and orthopedic surgery, Dr. LaMasters said. In randomized, controlled studies, this optimization is associated with decreased complications, mortality, and length of hospital stay.
“There is actually way less data from bariatric studies. I suggest to you that our bariatric surgery patients have similar comorbidities when compared with those other specialties – specialties that refer their patients to us for treatment,” Dr. LaMasters said.
In a study of cardiorespiratory fitness before bariatric surgery, other researchers found that the most serious postoperative complications occurred more often among patients who were less fit preoperatively (Chest. 2006 Aug;130[2]:517-25). These investigators measured peak oxygen consumption (VO2) preoperatively in 109 patients. “Each unit increase in peak VO2 rate was associated with 61% decrease in overall complications,” Dr. LaMasters said. “So a small increase in fitness led to a big decrease in complications.”
Other researchers compared optimization of exercise, nutrition, and psychological factors before and after surgery in 185 patients with colorectal cancer (Acta Oncol. 2017 Feb;56[2]:295-300). A control group received the interventions postoperatively. “They found a statistically significant difference in the prehabilitation group in increased functional capacity, with more than a 30-meter improvement in 6-minute walk test before surgery,” Dr. LaMasters said. Although the 6-minute walk test results decreased 4 weeks after surgery, as might be expected, by 8 weeks the prehabilitation patients performed better than controls – and even better than their own baseline, she added. “This model of optimization can be very well applied in bariatric surgery.”
“The goal is safe surgery with outstanding long-term outcomes,” Dr. LaMasters said. “It is really not enough in this era to ‘get a patient through surgery.’ We really need to optimize the risk factors we can and identify any areas where they will have additional needs after surgery,” she added. “This will allow us to have excellent outcomes in this complex patient population.”

AT THE ACS QUALITY & SAFETY CONFERENCE
MBSAQIP data helped target problem areas to cut readmissions
NEW YORK – Targeted interventions aimed at reducing patient readmission after bariatric surgery at a high-volume academic medical center led to a 61% overall decrease year over year. The center also saw a substantial reduction in readmissions linked to the top three factors of readmission identified by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program, as well as a precipitous drop in the revisional surgery readmission rate.
“Our center, like so many others, has quarterly meetings in accordance with the MBSAQIP to look at our data. And this led to recognition of some common reasons for readmission,” said Chetan V. Aher, MD, a general surgeon at the department of surgery at Vanderbilt University Medical Center in Nashville, Tenn. Oral (PO) intolerance, dehydration, and nonemergent abdominal pain were the top reasons flagged by the MBSAQIP registry data at the medical center. Dr. Aher and his colleagues moved to focus on postoperative diet, administration of medications, management of patients who return to the hospital after surgery, and optimal staffing.
After comparing MSBAQIP data for 471 bariatric operations in 2015 with data from 539 surgeries in 2016, “we saw a pretty significant reduction in our readmission rates. Overall we had a decrease of 61%, from 6.6% to 2.6%.” There was also a 45% decrease in readmission rates related to the top three reasons – PO intolerance, dehydration, and nonemergent abdominal pain – combined.
“Notably, the readmission rate for revisional procedures decreased by a whopping 90%,” Dr. Aher said. “I think a lot of these targeted interventions just really helped these patients who were at a higher risk to begin with to be readmitted.”
New dietary dos and don’ts
“We changed our postoperative diet,” Dr. Aher said. Instead of a soft food diet a couple of days after surgery, the full liquid diet was extended to 3 weeks post surgery.
The clinicians also implemented what they called a ‘no MEALS’ policy, which stands for no Meat, Eggs And Leftovers. “We were having problems with meat, although tender fish was okay, and some other things that went down easily,” Dr. Aher said at the American College of Surgeons Quality and Safety Conference. “We had some complaints about no eggs after surgery. A lot of patients love eggs,” he added. But they recommended avoiding eggs for 1 month after bariatric surgery to avoid nausea.
“Avoiding leftovers was also a big deal for patients,” Dr. Aher said. But patients who microwaved leftovers would “then come into the hospital with problems.”
Medication modifications
Another frequent cause of nausea was a “terrible and off-putting” taste when crushed tablets or medication capsules were added to the patient’s diet. Changing how patients took their medication “was a big help.” At the same time, there was a large institutional effort at Vanderbilt to start providing discharge medications in the hospital to increase postoperative compliance. “Bariatric surgery was one of the pilot programs for this,” Dr. Aher said. Discharge medications were filled by the pharmacy at Vanderbilt and delivered to the patient’s room, and a pharmacist or pharmacy intern explained how to use them. Compliance on medications increased, which may in turn have had an impact on readmissions.
Changes to patient management
Dr. Aher and his colleagues also changed where they treated patients who returned with problems. “Previously, when patients called in, the clinic diverted them to the emergency room. We stopped doing that, and increased our capacity to see these patients in the clinic instead.” This led to an increase in use of IV hydration in the clinic.
A meeting attendee asked if providing this service led to any problems with clinic capacity.
“Sometimes,” Dr. Aher said. “We don’t have a huge number of patients coming in for IV hydration, but when we had two come in on the same day, it did take up a couple of exam rooms.” To address this, the clinicians found other space in the clinic that would offer privacy for patients while not tying up exam rooms.
In addition, the clinic expanded nurse practitioner availability to 5 days a week to make the discharge process more consistent. “Of course, as we rolled all these things out, we made sure our educational material was updated accordingly,” Dr. Aher said.
The study demonstrates that a collaborative team effort and targeted interventions can result in a significant reduction in readmissions, Dr. Aher said. “Regular quality focused meetings are really important to facilitate recognition of various areas for improvement, especially in a high-volume center. Introducing an MBSAQIP registry serves as an excellent tool to effect these changes,” he said.
