Bariatric surgery comes with some risk of complications
that should acknowledged by clinicians and understood by patients, a large cohort study has shown.
Gunn Signe Jakobsen, MD, of Vestfold Hospital Trust, Tønsberg, Norway, and her colleagues wrote in an article published in JAMA, “Few studies report long-term complication rates. ... No large-scale clinical practice–based study has compared the long-term association of bariatric surgery and specialized medical obesity treatment with obesity-related somatic and mental comorbidities, nor the irrespective complication rates.”
The investigators compared outcomes from 932 patients who underwent bariatric surgery and 956 who underwent specialized medical treatment that involved either individual or group lifestyle intervention programs. The study population included 1,249 women and 639 men with an average age of 44 years and an average baseline body mass index of 44 kg/m2.
The surgery patients were more likely than the medical treatment patients to have hypertension remission (absolute risk 32% vs. 12%, respectively), and less likely to develop new-onset hypertension (absolute risk 4% vs. 12%, respectively). Diabetes remission was significantly higher among surgery patients, compared with medical treatment patients (58% vs. 13%) as was the likelihood of dyslipidemia remission (43% vs. 13%). Surgery patients also were less likely to develop new-onset diabetes or dyslipidemia than the medical treatment patients.
However, more patients who underwent bariatric surgery had low ferritin levels, compared with the medical treatment patients (26% vs. 12%). The surgery patients were significantly more likely than the medical treatment patients to develop new-onset depression (adjusted relative risk, 1.5; 95% confidence interval, 1.4-1.7), anxiety and sleep disorders (aRR, 1.3; 95% CI, 1.2-1.5), and treatment with opioids (aRR, 1.3; 95% CI, 1.2-1.4). In addition, bariatric patients were more likely to have at least one additional gastrointestinal surgical procedure (aRR, 2.0; 95% CI, 1.7-2.4), an operation for intestinal obstruction (aRR, 10.5; 95% CI, 5.1-21.5), abdominal pain (aRR, 1.9; 95% CI, 1.6-2.3), and gastroduodenal ulcers (aRR, 3.4; 95% CI 2.0-5.6).
The study was limited by several factors, including selection bias of younger, heavier patients in the bariatric surgery group, the lack of data on actual weight loss, incomplete laboratory data, and a relatively homogeneous white population, the researchers noted. However, the nearly 100% follow-up over approximately 6 years adds to the strength of the findings, which suggest that “the risk for complications should be considered in the decision-making process,” for obese patients considering bariatric surgery, they said.

Metabolic and bariatric surgery reduces CVD risk in severely obese adolescents
Weight loss caused by metabolic and bariatric surgery (MBS) independently predicts the normalization of dyslipidemia, elevated blood pressure (EPB), hyperinsulinemia, diabetes, and elevated high-sensitivity C-reactive protein (hs-CRP) in severely obese adolescents, according to results of a longitudinal, multicenter prospective study.
In the study of 242 severely obese adolescents undergoing MBS between Feb. 28, 2007, and Dec. 30, 2011, Marc Michalsky, MD, of Nationwide Children’s Hospital, Columbus, Ohio, and his colleagues found that with every 10% increase in weight loss, patients were 24%, 11%, 14%, 13%, and 19% more likely to resolve dyslipidemia, EBP, hyperinsulinemia, diabetes, and elevated hs-CRP, respectively.
One of the most important facets of this study is the predictive nature of different patient risk factors on the future remission of cardiovascular disease symptoms.
For example, “the evidence suggests that better long-term outcomes may be anticipated among individuals undergoing MBS at lower BMI levels (i.e., less than 50),” they reported in the journal Pediatrics. “Increasing age at the time of MBS was associated with a reduced likelihood of dyslipidemia remission and normalization of hs-CRP,” which was true even in the narrow age range of this group of adolescents.
“The identification of specific predictors of CVD-RF [cardiovascular disease risk factors] normalization and/or remission on the basis of sex, race, preoperative BMI, and age at surgery may serve to improve future study design and insights regarding the optimization of treatment strategies,” wrote Dr. Michalsky and his colleagues. “Collectively, these data demonstrate a reduction in the risk for development of CVD in adulthood and offer additional, compelling support for MBS in adolescents.”

Alcohol use, abuse rise after bariatric surgery
ORLANDO –
Following any of several methods of bariatric surgery, patients showed a statistically significant 8% higher rate of new onset alcohol abuse, and a relative 50% increased rate of significant alcohol use, compared with rates before surgery, Prandeet Wander, MD, said at the World Congress of Gastroenterology at ACG 2017.
Her meta-analysis identified prospective, retrospective, and cross-sectional studies of alcohol use that included more than 100 bariatric surgery patients and that had follow-up beyond 1 year. Patients could have undergone Roux-en-Y gastric bypass, sleeve gastrectomy, or laparoscopic adjustable gastric banding. Comparator populations had to be either the surgery patients prior to the procedure or the controls matched by age and body mass index.
The 28 included studies enrolled 15,714 patients who averaged 43 years old, with more than three quarters women. Follow-up averaged 2.6 years. The most common surgery was Roux-en-Y, used in 23 studies, followed by banding in 12 studies, and sleeves in 8 studies (some studies used more than one type of surgery).
Nineteen of the studies examined the prevalence of “significant alcohol abuse” following surgery in a total of 4,552 patients, with 23% of patients overall showing this behavior. Five studies, involving 2,698 patients, documented the rate of new-onset alcohol abuse after surgery, with an overall rate of 8% that was statistically significant. All five studies individually showed increased incidence of alcohol abuse, with rates that ranged from 4% to 8%.
The analysis that showed a relative 50% higher rate of “significant” alcohol use after surgery, compared with the same patients before their surgery used data from 11 studies with 3,370 patients. Five of these 11 studies individually showed a statistically significant increase in alcohol use, 1 showed a significant, 34% relative decrease, and the remaining 5 studies did not show statistically significant changes, with 3 studies trending toward an increased rate and two trending toward a decreased rate after surgery.
None of the 28 included studies had a randomized control arm, and the studies collectively ran in six countries, including the United States, and hence involved different societal norms of alcohol use. Changes in alcohol absorption and metabolism following bariatric surgery may play roles in the observed effects, as might undiagnosed depression or substance use by patients who undergo this surgery, Dr. Wander suggested.

Hispanics trail blacks, whites in bariatric surgery rates
SAN DIEGO – A study of procedures at academic centers provides evidence that obese Hispanics in the United States undergo bariatric surgery at a much lower rate than whites and blacks. It also reveals marked regional variations in overall weight-loss surgery.
“Our findings do suggest that severely obese Hispanics are utilizing bariatric surgery much lower than other ethnic groups,” said study coauthor Ninh T. Nguyen, MD, FACS, chair of the department of surgery at the University of California Irvine Medical Center, in an interview. “Our research does not specifically address the reasons for this gap in the delivery of care. Further research will need to be done to understand the reasons and the ways to close this gap.”
According to Dr. Nguyen, the researchers undertook the study to better understand how bariatric surgery is delivered across ethnicities and geographic regions in the United States.
The researchers analyzed statistics from the Vizient health care performance database for the years 2013-2015. They focused on patients at about 120 academic centers who underwent 73,119 laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic adjustable gastric banding procedures. The patients were stratified by race and region.
Researchers found that bariatric procedures were performed at a much higher rate in the Northeast academic centers (2.21 per 1,000 obese persons), compared with the Midwest (0.73), South (0.50), and West (0.33).
In regard to race, the rates for blacks and whites were fairly similar in the Northwest (2.02 and 2.35 bariatric procedures per 1,000 obese persons, respectively), the South (0.59 and 0.63, respectively) and the West (0.45 and 0.43, respectively). There was a wider gap in the Midwest, with whites at 0.69 and blacks at 1.07.
Across the country, however, obese Hispanics were less likely than persons of the other two races to undergo weight-loss surgery. The gap was fairly small in the Northeast, where 1.74 per 1,000 obese Hispanics underwent weight-loss surgery, compared with rates of 2.02 and 2.35 among whites and blacks, respectively. But the disparity was much larger in the other parts of the country, with rates at 0.14 in the West, 0.11 in the South and 0.33 in the Midwest, compared with rates from 0.43 to 1.07 among blacks and whites.
The reasons for the surgery gap are unknown. Dr. Nguyen pointed to several possible explanations: “lack of education of obesity as a disease by the primary care providers and the need for referral to a bariatric surgeon for patients with body mass index greater than 40 kg/m2 or 35 kg/m2 with obesity-related comorbidities; poor understanding of the benefits of bariatric surgery and its low risk; lack of understanding of the urgency for treatment by the patient and provider; and hurdles in obtaining coverage for the operation by insurers.”
John Magaña Morton, MD, FACS, chief of bariatric and minimally invasive surgery at Stanford (Calif.) University School of Medicine and past president of the American Society for Metabolic and Bariatric Surgery, doesn’t think discrimination is causing the disparity.
“It’s probably a reflection of insurance status – Hispanics tend to be less insured than Caucasian or African American patients – as well as preference for patients to go to nonacademic centers,” he said.
Indeed, a Kaiser Family Foundation analysis found that 21% of the 52 million Hispanics younger than 65 years in the United States were uninsured in 2015, compared with 9% of whites and 13% of blacks. Only Native Americans/Alaska Natives had an uninsured rate as high as Hispanics.
“In terms of need [for weight-loss features], it’s certainly there for Hispanics,” said Dr. Morton. “[Hispanic patients] have high rates of obesity and diabetes, both of which are helped by bariatric surgery.”
He said about 40% of patients in his Palo Alto, Calif., practice are Hispanic, reflecting the high number in the local population.
It helps that Dr. Morton and several of his partners speak Spanish. “If you have a welcoming environment,” he said, “that can make a difference.”
The study authors and Dr. Morton report no relevant disclosures. No specific study funding is reported.

John Magaña Morton, MD, FACS, chief of bariatric and minimally invasive surgery at Stanford (Calif.) University School of Medicine and past president of the American Society for Metabolic and Bariatric Surgery, doesn’t think discrimination is causing the disparity.
“It’s probably a reflection of insurance status – Hispanics tend to be less insured than Caucasian or African American patients – as well as preference for patients to go to nonacademic centers,” he said.
Indeed, a Kaiser Family Foundation analysis found that 21% of the 52 million Hispanics younger than 65 years in the United States were uninsured in 2015, compared with 9% of whites and 13% of blacks. Only Native Americans/Alaska Natives had an uninsured rate as high as Hispanics.
“In terms of need [for weight-loss features], it’s certainly there for Hispanics,” said Dr. Morton. “[Hispanic patients] have high rates of obesity and diabetes, both of which are helped by bariatric surgery.”
He said about 40% of patients in his Palo Alto, Calif., practice are Hispanic, reflecting the high number in the local population.
It helps that Dr. Morton and several of his partners speak Spanish. “If you have a welcoming environment,” he said, “that can make a difference.”

SAN DIEGO – A study of procedures at academic centers provides evidence that obese Hispanics in the United States undergo bariatric surgery at a much lower rate than whites and blacks. It also reveals marked regional variations in overall weight-loss surgery.
“Our findings do suggest that severely obese Hispanics are utilizing bariatric surgery much lower than other ethnic groups,” said study coauthor Ninh T. Nguyen, MD, FACS, chair of the department of surgery at the University of California Irvine Medical Center, in an interview. “Our research does not specifically address the reasons for this gap in the delivery of care. Further research will need to be done to understand the reasons and the ways to close this gap.”
According to Dr. Nguyen, the researchers undertook the study to better understand how bariatric surgery is delivered across ethnicities and geographic regions in the United States.
The researchers analyzed statistics from the Vizient health care performance database for the years 2013-2015. They focused on patients at about 120 academic centers who underwent 73,119 laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, and laparoscopic adjustable gastric banding procedures. The patients were stratified by race and region.
Researchers found that bariatric procedures were performed at a much higher rate in the Northeast academic centers (2.21 per 1,000 obese persons), compared with the Midwest (0.73), South (0.50), and West (0.33).
In regard to race, the rates for blacks and whites were fairly similar in the Northwest (2.02 and 2.35 bariatric procedures per 1,000 obese persons, respectively), the South (0.59 and 0.63, respectively) and the West (0.45 and 0.43, respectively). There was a wider gap in the Midwest, with whites at 0.69 and blacks at 1.07.
Across the country, however, obese Hispanics were less likely than persons of the other two races to undergo weight-loss surgery. The gap was fairly small in the Northeast, where 1.74 per 1,000 obese Hispanics underwent weight-loss surgery, compared with rates of 2.02 and 2.35 among whites and blacks, respectively. But the disparity was much larger in the other parts of the country, with rates at 0.14 in the West, 0.11 in the South and 0.33 in the Midwest, compared with rates from 0.43 to 1.07 among blacks and whites.

In bariatric surgery, leak test may backfire
SCOTTSDALE, ARIZ. – A test used to detect anastomotic leaks during bariatric surgery may in fact be a potential cause of leaks, since performance of the test was associated with double the frequency of 30-day postoperative leaks, a study showed.
Based on this finding from an analysis of the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database, the researchers suggested that the use of an endoscope could lead to fewer complications.
The test itself is valuable, since surgeons hope to find and repair a leak immediately, but Dr. Nguyen said the wrong method is being used. “The technique of doing the test should be endoscopy rather than the use of an orogastric tube,” he said. The database did not indicate which technique was being used, but Dr. Nguyen said that use of endoscopy is rare. Surgeons “don’t want to break scrub to go around and perform the endoscopy. It’s easier to ask the anesthesiologist to put a tube down,” said Dr. Nguyen, who is chair of surgery at University of California Irvine Medical Center.
The study, which was presented at the annual meeting of the Western Surgical Association, is the first to look at intraoperative and postoperative procedures and risk of leaks during bariatric surgery, and was possible only because of the recent availability of the MBSAQIP database. The study cannot prove causation between performance of the provocative test and heightened leak risk, and one audience member suggested the possibility that the tests were ordered when a surgeon believed the patient was at higher risk. If so, the association wouldn’t be causative.
However, the provocation test was performed 82% of the time, suggesting that the test was being carried out routinely, said Dr. Nguyen.
By contrast, when the surgeon inserted a surgical drain, the risk of leak was nearly four times higher. “It is most likely that the surgeon only decided to place the drain because they were worried about that particular operation, since it was only done a small percentage of the time. Our results suggest that they were right [to be concerned]. We believe it’s a reflection of the knowledge of the surgeon for that particular case,” said Dr. Nguyen.
If indeed there is a risk associated with the provocation test, the use of endoscopy could reduce that risk. Dr. Nguyen also pointed out that endoscopy provides anatomical detail that can help guide revision surgery, and it’s a useful training exercise for residents. “This is an important skill that you need when you graduate from general surgery,” said Dr. Nguyen.
The researchers analyzed data from 133,478 patients who underwent laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB), excluding emergent and revisional cases; 69.3% of patients underwent LSG, while 30.7% underwent LRYGB. The researchers looked at the association between leak frequency and the presence of the provocative test, surgical drain, and swallow study.
The 30-day leak rate was 0.7% overall, and 0.5% in LSG and 1.2% in LRYGB (adjusted odds ratio for LSG, 0.52; 95% confidence interval, 0.44-0.61; P less than .001). The rate was higher in the 81.9% of patients who received the provocative test than in those who did not (0.8% vs. 0.4%; aOR, 1.41; 95% CI, 1.14-1.76; P = .02). The leak risk was also higher in the 24.5% of patients who had a drain placed (1.6% vs. 0.4%; aOR, 3.46; 95% CI, 3.01-3.98; P less than .001).
A total of 41.1% of patients received a swallow study, but their leak rate (0.7%) was identical to that of those who did not have a swallow study.
The study received no outside funding. Dr. Nguyen reported having no relevant financial disclosures.

VIDEO: Bariatric experts discuss recent experience with gastric balloon devices
Two experts on bariatric surgery spoke at the Minimally Invasive Surgery Symposium, held in Las Vegas. Jaime Ponce, MD, FACS, and John Morton, MD, FACS, discussed several different types of gastric balloon devices and the factors guiding their use for patients. Dr. Morton suggested that the balloon devices could serve as an intermediate treatment between medications and surgery.

Large database analysis suggests safety of bariatric surgery in seniors
NATIONAL HARBOR, MD. – despite a slight increase in unadjusted mortality rates, according to an analysis of data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP).
Based on data that was collected in 2015 and submitted to MBSAQIP, “bariatric surgery is safe in the elderly, even in those 70 years old and older,” reported Tallal Zeni, MD, director of the Michigan Bariatric Institute in Livonia.
There were 16,568 patients older than age 60 years entered into the MBSAQIP database in 2015. When those were compared with the 117,443 younger patients, the unadjusted rates of morbidity (6.5% vs. 6.0%) and mortality (0.3% vs. 0.1%) were higher for the older patients, but “they are close,” according to Dr. Zeni. Both rates reached significance by the conventional definition (P < .05), but he suggested that they are lower in this study than those in prior studies of MBSAQIP datasets and that they are acceptable relative to the anticipated health benefits.
Above the age of 60 years, no correlation could be made between increasing age and increasing risk of morbidity, mortality, or rate of reoperations, according to Dr. Zeni.
Why should bariatric surgery be considered in older patients? He cited data from a study that showed the life expectancy in a 70-year-old without functional limitations is 13 years. As a result, he added, “it behooves us to provide them with the best quality of life we can.”
Relative to prior MBSAQIP evaluations of bariatric surgery in the elderly, the proportion of patients undergoing sleeve gastrectomy relative to gastric bypass has been increasing, Dr. Zeni reported. In the analysis, approximately two-thirds of the bariatric procedures were performed with sleeve gastrectomy, which is higher relative to what previous MBSAQIP analyses have shown.
Based on rates of morbidity for those two surgical approaches in the analysis, that trend makes sense. While the higher 30-day mortality for gastric bypass, compared with sleeve gastrectomy, was not significant (0.38% vs. 0.26%; P = .221), all-cause morbidity was almost two times greater for those undergoing gastric bypass than it was for those undergoing sleeve gastrectomy (10.61% vs. 5.81%; P < .001), Dr. Zeni reported.
However, some of that difference may be explained by baseline disparities between the two groups. In the gastric bypass group, there were higher rates of preoperative diabetes (54% vs. 40%; P < .001), sleep apnea (57% vs. 50%; P < .001) and hyperlipidemia (59% vs. 54%; P < .001). Also, gastric bypass patients were more likely to have a history of a previous bariatric procedure (11% vs. 8.5%; P < .001) and to be in the American Society of Anesthesiologists Physical Status score of 3 (84% vs. 80%; P < .001), according to Dr. Zeni.
The specific complications more common in the gastric bypass group than the sleeve gastrectomy group included anastomotic leak (0.56% vs. 0.3%; P = .017), surgical site infection (1.74% vs. 0.61%; P < .001), pneumonia (0.87% vs. 0.32%; P < .001), and bleeding (1.14% vs. 0.5%; P = .024). Although the average operating time was 40 minutes longer in the bypass group, there were no significant differences in thromboembolic complications.
Overall, despite a modest increase in the risk of complications for bariatric surgery in elderly patients, that risk can be considered acceptable in relation to the potential health benefits, according to Dr. Zeni. He suggested that the data might encourage further growth in the rates of bariatric procedures among patients older than 60 years.

The study (Ann Surg. 2016;264[3]:464-73) looked at outcomes, methods, and complications of this procedure based on a database of nearly 190,000 patients, more than 1,600 surgeons, and 720 centers. Dr. Hutter said that is high-quality data that offers surgeons good information on the procedure.

Gastrectomy mortality risk increased fivefold with same-day discharge
NATIONAL HARBOR, MD. – Laparoscopic sleeve gastrectomy has been associated with low mortality, but the mortality is even lower when it includes overnight observation, according to a national database evaluation.
Among patients discharged on the same day, 30-day mortality was 0.1%, but it fell to 0.02% among patients discharged the following day, according to Colette Inaba, MD, a surgery resident at the University of California, Irvine.*
“Surgeons who are considering same-day discharge in sleeve gastrectomy patients should have a low threshold to admit these patients for overnight observation given our findings,” Dr. Inaba reported at an annual meeting presented by the American Society for Metabolic and Bariatric Surgery and The Obesity Society.
Same-day discharge has been associated with an increased mortality risk in previously published descriptive institutional reviews, but this is the first study to evaluate this question through analysis of a national database, according to Dr. Inaba. It was based on 37,301 laparoscopic sleeve gastrectomy cases performed in 2015 and submitted to the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. All participants in this database are accredited bariatric centers.
There were baseline differences between same-day and next-day discharges, but many of these differences conferred the next-day group with higher risk. In particular, the next-day group had significantly higher rates of hypertension, diabetes mellitus, hypercholesterolemia, chronic obstructive pulmonary disease, and sleep apnea. On average, the procedure time was 13 minutes longer in the next-day versus the same-day discharge groups.
In addition to mortality, 30-day morbidity and need for revisions were compared between the two groups, but there were no significant differences between groups in the rates of these outcomes.
Overall, the baseline demographics of the patients in same-day and next-day groups were comparable, according to Dr. Inaba. She described the population as predominantly female and white with an average body mass index of 45 kg/m2. In this analysis, only primary procedures (excluding redos and revisions) were included.
Relative to the next-day discharge cases, a significantly higher percentage of same-day discharge procedures were performed with a surgical tech or another provider rather than a designated first-assist surgeon, according to Dr. Inaba. For next-day cases, a higher percentage was performed with the participation of fellows or surgical residents. There were fewer swallow studies performed before discharge in the same-day discharge group.
Very similar results were generated by a study evaluating same-day discharge after laparoscopic Roux-en-Y gastric bypass, according to John M. Morton, MD, chief of bariatric and minimally invasive surgery, Stanford (Calif.) University. Dr. Morton, first author of the study and moderator of the session in which Dr. Inaba presented the LSG data, reported that same-day discharge in that study was also associated with a trend for an increased risk of serious complications (Ann Surg. 2014;259:286-92).
“Same-day discharge is often reimbursed at a lower rate, so there is less pay and patients are at greater risk of harm,” Dr. Morton said.
The reasons that same-day discharge is associated with higher mortality cannot be derived from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, but, Dr. Inaba said, “Our thought is it is a function of failure to rescue patients from respiratory complications.” She acknowledged that this is a speculative assessment not supported by data, but she suggested that history of sleep apnea might be a particular indication to consider next-day discharge.
Dr. Inaba reports no financial relationships relevant to this topic.
