Abstract
As management of upper gastrointestinal malignancies improves, and with popularization of bariatric surgery, endoscopists are likely to meet patients with altered upper gastrointestinal anatomy. Short-term, the surgery can cause complications like bleeding, leaks, and fistulas, and longer-term problems such as intestinal or biliary anastomotic strictures or biliary stones can arise, all necessitating endoscopy. In addition, the usual upper gastrointestinal pathologies can also still occur. These patients pose unique challenges. To proceed, understanding the new layout of the upper gastrointestinal tract is essential. The endoscopist, armed with a clear plan for navigation, can readily diagnose and manage most commonly occurring conditions, such as marginal ulcers and proximal anastomotic strictures with standard endoscopic instruments. With complex reconstructions involving long segments of small bowel, such as Roux-en-Y gastric bypass, utilization of balloon-assisted enteroscopy may be necessary, mandating modification of procedures such as endoscopic retrograde cholangiopancreatography. Successful endoscopic management of patients with altered anatomy will require prior planning and preparation to ensure the appropriate equipment, setting, and skill set is provided.

Obes Surg 2024:10.1007/s11695-024-07321-2. [PMID: 38811426 DOI: 10.1007/s11695-024-07321-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 05/23/2024] [Accepted: 05/23/2024] [Indexed: 05/31/2024]
Abstract
PURPOSE After Roux-en-Y gastric bypass (RYGB), few patients develop severe complications, which ultimately may require reversal of RYGB. We aimed to examine the effect of reversal of RYGB on symptoms and well-being. MATERIALS AND METHODS Via contact to medical and surgical departments treating patients with RYGB, we identified 18 patients, who had undergone reversal, 2009-2019. We conducted a Danish, nationwide questionnaire survey concerning symptoms before and after reversal of the RYGB including the patients' own perceptions of their well-being. RESULTS Fourteen patients responded to the questionnaire (86% female; median age at RYGB, 36.2 years [IQR, 30.9-38.6 years]). The median time from RYGB to reversal was 5.8 years (IQR, 5.1-7.5 years). After RYGB, 13 patients (93%) reported abdominal pain, while 12 patients still had abdominal pain after reversal. Six out of 11 patients (45%) reported complete remission of dumping/post-bariatric hypoglycemia (PBH) after reversal. Malabsorption disappeared in 10 out of 11 patients (90%). Reversal had minor effect on neuropathy. The median weight loss from RYGB was 61 kg (IQR, 56-75 kg), while the median weight regain after reversal was 30 kg (IQR, 13-46 kg). Regarding the well-being, 72 of the patients felt better or much better after reversal. CONCLUSION In total, 72% of the patients felt better or much better after reversal of RYGB, though some still had RYGB-related symptoms. The reversal relieved dumping/PBH and malabsorption, but not abdominal pain and neuropathy. Finally, half of the weight loss was regained after reversal. Reversal of RYGB may be an option in highly selected cases.

Abstract
Obesity is a chronic, relapsing, progressive disease of excess adiposity that increases the risk of developing at least 13 types of cancer. This report provides a concise review of the current state of the science regarding metabolic and bariatric surgery and obesity pharmacotherapy related to cancer risk. Meta-analyses of cohort studies report that metabolic and bariatric surgery is independently associated with a lower risk of incident cancer than nonsurgical obesity care. Less is known regarding the cancer-preventive effects of obesity pharmacotherapy. The recent approval and promising pipeline of obesity drugs will provide the opportunity to understand the potential for obesity therapy to emerge as an evidence-based cancer prevention strategy. There are myriad research opportunities to advance our understanding of how metabolic and bariatric surgery and obesity pharmacotherapy may be used for cancer prevention.

Obes Surg 2023:10.1007/s11695-023-06564-9. [PMID: 37012503 DOI: 10.1007/s11695-023-06564-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 03/23/2023] [Accepted: 03/28/2023] [Indexed: 04/05/2023]
Abstract
PURPOSE Metabolic and bariatric surgery (MBS) has been associated with reduced all-cause mortality. While the number of subjects with substance use disorders (SUD) before MBS has been documented, the impact of pre-operative SUD on long-term mortality following MBS is unknown. This study assessed long-term mortality of patients with and without pre-operative SUD who underwent MBS. MATERIALS AND METHODS Two statewide databases were used for this study: Utah Bariatric Surgery Registry (UBSR) and the Utah Population Database. Subjects who underwent MBS between 1997 and 2018 were linked to death records (1997-2021) to identify any death and cause for death following MBS. All deaths (internal, external, and unknown reasons), internal deaths, and external deaths were the primary outcomes of the study. External causes of death included death from injury, poisoning, and suicide. Internal causes of death included deaths that were associated with natural causes such as heart disease, cancer, and infections. A total of 17,215 patients were included in the analysis. Cox regression was used to estimate hazard ratios (HR) of controlled covariates, including the pre-operative SUD. RESULTS The subjects with pre-operative SUD had a 2.47 times higher risk of death as compared to those without SUD (HR = 2.47, p < 0.01). Those with pre-operative SUD had a higher internal cause of death than those without SUD by 129% (HR = 2.29, p < 0.01) and 216% higher external mortality risk than those without pre-operative SUD (HR = 3.16, p < 0.01). CONCLUSION Pre-operative SUD was associated with higher hazards of all-cause, internal cause, and external cause mortality in patients who undergo bariatric surgery.

Efficacy and safety of laparoscopic Roux-en-Y gastric bypass in symptomatic patients following fundoplication failure: a meta-analysis. Esophagus 2023; 20:184-194. [PMID: 36348250 DOI: 10.1007/s10388-022-00969-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 10/29/2022] [Indexed: 11/09/2022]
Abstract
Revisional surgery may be required in a subset of patients who remain symptomatic despite undergoing laparoscopic fundoplication (LF) for gastroesophageal reflux disease (GERD). While revisional LF (RLF) is feasible in these patients, laparoscopic Roux-en-Y gastric bypass (LRYGB) may serve as an alternative, although its efficacy and safety remains unknown. This study aimed to determine the outcomes of LRYGB in symptomatic patients following failed LF for GERD. MEDLINE, EMBASE, and PubMed databases were systematically searched for studies reporting LRYGB outcomes in symptomatic adults despite undergoing LF for GERD. Postoperative symptom resolution, recurrence of heartburn and dysphagia, proton pump inhibitor (PPI) use, and body mass index (BMI) reduction were assessed to determine LRYGB efficacy. Postoperative morbidity and mortality were used to evaluate LRYGB safety. Twenty-two studies with 1523 patients were included. Pooled rates of symptom resolution, recurrence of heartburn and dysphagia, PPI use, morbidity, and mortality were 71.6% (95% CI 59.4-86.4), 15.6% (8.9-27.3), 20.7% (12.5-34.3), 29.6% (18.8-46.5), 39.5% (29.9-52.3), and 2.2% (1.2-4.0), respectively, following LRYGB. Similar rates were observed after RLF. However, BMI reduction was significantly greater after LRYGB compared with RLF (mean difference 6.1 kg/m2, 4.8-7.4; p < 0.0001). LRYGB resulted in symptom relief in a majority of patients, and proved comparable to RLF regarding symptom recurrence and PPI use. Morbidity and mortality following LRYGB also did not differ from RLF. However, LRYGB was associated with considerably greater weight loss relative to RLF. Therefore, LRYGB is efficacious and an acceptable revisional procedure in symptomatic GERD patients who have previously undergone LF.

Abstract
The study aimed to perform a systematic review and meta-analysis of the evidence for the prevention of future cancers following bariatric surgery. A systematic literature search of the Cochrane Library, Embase, Scopus, Web of Science and PubMed databases (2007–2023), Google Scholar and grey literature was conducted. A meta-analysis was performed using the inverse variance method and random effects model. Thirty-two studies involving patients with obesity who received bariatric surgery and control patients who were managed with conventional treatment were included. The meta-analysis suggested bariatric surgery was associated with a reduced overall incidence of cancer (RR 0.62, 95% CI 0.46–0.84, p < 0.002), obesity-related cancer (RR 0.59, 95% CI 0.39–0.90, p = 0.01) and cancer-associated mortality (RR 0.51, 95% CI 0.42–0.62, p < 0.00001). In specific cancers, bariatric surgery was associated with reduction in the future incidence of hepatocellular carcinoma (RR 0.35, 95% CI 0.22–0.55, p < 0.00001), colorectal cancer (RR 0.63, CI 0.50–0.81, p = 0.0002), pancreatic cancer (RR 0.52, 95% CI 0.29–0.93, p = 0.03) and gallbladder cancer (RR 0.41, 95% CI 0.18–0.96, p = 0.04), as well as female specific cancers, including breast cancer (RR 0.56, 95% CI 0.44–0.71, p < 0.00001), endometrial cancer (RR 0.38, 95% CI 0.26–0.55, p < 0.00001) and ovarian cancer (RR 0.45, 95% CI 0.31–0.64, p < 0.0001). There was no significant reduction in the incidence of oesophageal, gastric, thyroid, kidney, prostate cancer or multiple myeloma after bariatric surgery as compared to patients with morbid obesity who did not have bariatric surgery. Obesity-associated carcinogenesis is closely related to metabolic syndrome; visceral adipose dysfunction; aromatase activity and detrimental cytokine, adipokine and exosomal miRNA release. Bariatric surgery results in long-term weight loss in morbidly obese patients and improves metabolic syndrome. Bariatric surgery may decrease future overall cancer incidence and mortality, including the incidence of seven obesity-related cancers.

Risk of Myocardial Infarction, Ischemic Stroke, and Mortality in Patients Who Undergo Gastric Bypass for Obesity Compared With Nonoperated Obese Patients and Population Controls. Ann Surg 2023; 277:275-283.

Abstract
OBJECTIVE The aim of this study was to estimate risks of myocardial infarction, ischemic stroke, and cardiovascular-related and all-cause mortality after Roux-en-Y gastric bypass (RYGB) for obesity compared with nonop-erated obese patients and matched nonobese population controls. BACKGROUND Few studies have assessed the influence of RYGB on fatal and non-fatal myocardial infarction and ischemic stroke, and the results vary between studies. METHOD All patients aged 20 to 65 years with obesity diagnosis in the nationwide Swedish Patient Registry in 2001 to 2013 were included. These participants were divided into those who underwent RYGB within 2 years of obesity diagnosis (n = 28,204) and nonoperated (n = 40,827), and were matched for age, sex, and region with 2 nonobese population controls. Participants were followed until onset of outcome disease, death, or end of follow-up. Multivariable Cox regression provided hazard ratios (HR) with 95% confidence intervals (95% CI). RESULTS Compared with nonoperated patients with obesity, RYGB patients had a reduced risk of myocardial infarction [HR = 0.44 (95% CI 0.28-0.63)], similar risk of ischemic stroke [HR = 0.79 (95% CI 0.54-1.14)], and decreased risks of cardiovascular-related [HR = 0.47 (95% CI 0.35-0.65)] and all-cause mortality [HR = 0.66 (95% CI 0.54-0.81)] within the first 3 years of follow-up, but not later. Compared with nonobese population controls, RYGB patients had excess risks of ischemic stroke [HR = 1.57 (95% CI 1.08-2.29)], cardiovascular-related mortality [HR = 1.82 (95% CI 1.29-2.60)], and all-cause mortality [HR = 1.42 (95% CI 1.16-1.74)], but not of myocardial infarction [HR = 1.02 (95% CI 0.72-1.46)]. CONCLUSION RYGB for obesity might not decrease the risk of ischemic stroke, but seems to decrease the risk of myocardial infarction back to population levels.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) is an effective treatment for obesity and may reduce mortality. Several factors are associated with higher mortality following MBS. The purpose of this study was to examine whether pre-operative arthritis was associated with long-term mortality following MBS. METHODS Using a retrospective cohort design, subjects who underwent MBS were identified from the Utah Bariatric Surgery Registry. These subjects were linked to the Utah Population Database. State death records from 1998 through 2021 were used to identify deaths following MBS. ICD-9/10 diagnosis codes were used to identify a pre-operative diagnosis of arthritis and to classify the cause of death. All causes of death, internal cause of death (e.g., diabetes, heart disease), and external cause of death (e.g., suicide) were defined as outcomes. Entropy balancing (EB) was applied to create weights to balance the baseline characteristics of the two groups. Weighted Cox proportional hazards regression was used to evaluate the association of pre-operative arthritis with long-term mortality following MBS. RESULTS The final sample included 15,112 patients. Among them, 36% had a pre-operative arthritis diagnosis. Average (SD) age was 48(12) years old at surgery, and 75% were female. Patients with pre-operative arthritis had 25% (p < 0.01) and 26% (p < 0.01) higher risk of all cause of death and internal cause of death, respectively, compared to patients without pre-operative arthritis. CONCLUSION Individuals with arthritis prior to MBS may have higher hazard of long-term mortality than those without pre-operative arthritis.

Abstract
The aims of this systematic review were to identify the prevalence of hypoglycemia among pregnant women treated with gastric bypass, and risk factors of hypoglycemic events in pregnancy. We searched MEDLINE, EMBASE, Cochrane, and Scopus databases from inception to April 6, 2021. Six studies investigating glucose metabolism in pregnancy following gastric bypass were included (n = 330). As assessed by the oral glucose tolerance test and continuous glucose monitoring, 57.6% (95% CI [40.1, 75.1]) of women with gastric bypass were exposed to hypoglycemia during pregnancy. No studies performed the mixed meal test, and no studies reported on risk factors associated with hypoglycemia. Further studies are required to determine the magnitude of hypoglycemia in these women's everyday-life using continuous glucose monitoring and mixed meal test.

Abstract
PURPOSE Compared to medical treatment, bariatric surgery reduces long-term mortality in persons with obesity. Some studies indicate that the effect only applies to patients above median age of cohorts, not to younger patients. Our objective was to assess the role of age in the reduction of mortality (global mortality and mortality for specific causes) through bariatric surgery. MATERIALS AND METHODS Data sources: PubMed, Cochrane Library, MEDLINE, and Embase. STUDY SELECTION studies reporting mortality in relation to median age of patients. DATA EXTRACTION AND SYNTHESIS pooled random effects of estimates of the risk of mortality in participants undergoing surgery compared with controls, as function of median age. RESULTS Mortality was lower in patients undergoing surgery than in controls (OR = 0.29, 95% CI 0.17-0.49). Below median age, the difference between surgery patients and controls was nonsignificant (OR = 0.78, 95% CI 0.57-1.06). Above median age, the difference was significant (OR = 0.23, 95% CI 0.12-0.44). In a subset of 5 studies, deaths due to various causes were less, and external causes-related deaths were more frequent in surgery than in controls. Below median age, deaths due to CVD were less frequent in surgery than in controls. Above median age, total deaths and deaths due to various causes (cardiovascular, diabetes, cancer, and other causes) were less in surgery than in controls. Publication bias was absent. CONCLUSION Compared with controls, bariatric surgery reduces long-term global mortality only above median age, not below median age. Also mortality due to specific causes is mainly reduced in persons above median age.

Abstract
INTRODUCTION Weight loss after bariatric surgery yields important health benefits. A multitude of observational studies have investigated the association of bariatric surgery for severe obesity with the risk of cancer. However, the results were debatable. The aim of the present study was to estimate the effect of bariatric surgery on overall cancer risk. METHODS A systematic literature search was performed to identify studies evaluating the association of bariatric surgery for severe obesity with the risk of cancer. Meta-analysis was performed to calculate combined prevalence. RESULTS Twenty-one cohort studies with 304,516 patients with obesity having under gone bariatric surgery and 8,492,408 patients with obesity as controls were included. Meta-analysis found decreased cancer risk to be associated with bariatric surgery (OR = 0.56, 95% CI = 0.48-0.66), both for the incidence of cancer (OR = 0.56, 95% CI = 0.46-0.68) and mortality of cancer (OR = 0.56, 95% CI = 0.41-0.75). In subgroup analysis, bariatric surgery was significantly associated with decreased breast cancer risk and endometrial cancer risk, but not associated with other cancer risk. CONCLUSIONS Our meta-analysis indicated that bariatric surgery for severe obesity was associated with decreased cancer risk, both for cancer incidence and mortality. Moreover, further studies estimating the functional effect and side effects may eventually provide a better, comprehensive understanding.

Abstract
Background Bariatric surgery may lead to symptomatic postprandial hypoglycaemia as a major side effect without established therapy so far. We aimed to develop an evidence-based study design of a clinical trial that tests treatment options and can provide useful patient-relevant evidence. Methods We searched systematically for guidance of core outcome sets to determine the most relevant types of outcomes and duration of such a trial. Our search comprised literature databases, a database of core outcome sets and self-help organizations. We then developed a simple online questionnaire based on interviews with German-speaking patients with postprandial hypoglycaemia after bariatric surgery. We recruited participants by reaching out to all German speaking endocrinologists in Switzerland and large Swiss bariatric centres. We asked for preferences regarding outcome types and acceptable duration of being included in a corresponding clinical trial. Results The literature search did not identify evidence-based guidance for informing our study design. Experience of clinical and research routine as well as patient interviews helped in identifying potential outcomes and the design of an online questionnaire. Therein, a total of 29 persons started the questionnaire and 22 answered questions related to the primary outcome. Of these, 17 (77.3%) deemed quality of life more relevant as primary outcome than the rate of hypoglycaemic episodes. A trial length of four weeks or longer was regarded as acceptable for 19 of 21 respondents to this question (91.4%) and of six months or longer for 12 respondents (56%). Conclusions In situations with no other guidance, a simple questionnaire may help to inform trial design decisions. This study identifies a patient preference for “quality of life” as a primary outcome and supports the evidence-based conception of a patient-centred clinical trial in postbariatric hypoglycaemia.

Abstract
OBJECTIVE To evaluate the glucose and insulin profiles during an oral glucose tolerance test (OGTT) after Roux-en-Y gastric bypass (RYGB) in symptomatic and asymptomatic patients. RESEARCH DESIGN AND METHODS This retrospective study consisted of two groups that had undergone RYGB. The symptomatic (S) group (n = 27) had an OGTT at presentation, whereas the asymptomatic (A) group (n = 99) had an OGTT 1 year after RYGB. Each group was subdivided into two groups, namely, those with glycaemia <54 mg/dL (S1/A1) and those with glycaemia >54 mg/dL (S2/A2) during OGTT. Most of the patients underwent OGTT preoperatively. RESULTS Preoperatively, the glucose and insulin levels, as well as the speed of increase and decrease, were similar in all groups. Postoperatively, the minimum glucose levels during the OGTT did not differ between the symptomatic and asymptomatic groups (55 ± 19 vs. 54 ± 17 mg/dL) or between the S1 and A1 subgroups (39 ± 7 vs. 43 ± 8 mg/dL). The peak glucose values were higher in the symptomatic versus the asymptomatic group (236 ± 52 vs. 189 ± 43 mg/dL; P <0.05) and in the S1 and S2 versus the A1 and A2 subgroups. The speed of glucose increase and decline was significantly higher in the symptomatic group versus the asymptomatic group, with the speed of glucose decline being the highest in the S1 subgroup. CONCLUSION Assessing hypoglycaemia after a gastric bypass remains challenging. Our study suggests that the main difference in glucose dynamics between symptomatic and asymptomatic patients might be the speed of glucose and insulin increase and decline during OGTT rather than the absolute values obtained.

Abstract
OBJECTIVE The aim of this study was to compare the use and short-term outcome of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in Sweden, Norway, and the Netherlands. BACKGROUND Although bariatric surgery is performed in high volumes worldwide, no consensus exists regarding the choice of bariatric procedure for specific groups of patients. METHODS Data from 3 national registries for bariatric surgery were used. Patient selection, perioperative data (severe complications, mortality, and rate of readmissions within 30 days), and 1-year results (follow-up rate and weight loss) were studied. RESULTS A total of 47,101 primary operations were registered, 33,029 (70.1%) RYGB and 14,072 (29.9%) SG. Patients receiving RYGB met international guidelines for having bariatric surgery more often than those receiving SG (91.9% vs 83,0%, P < 0.001). The 2 procedures did not differ in the rate of severe complications (2.6% vs 2.4%, P = 0.382), nor 30-day mortality (0.04% vs 0.03%, P = 0.821). Readmission rates were higher after RYGB (4.3% vs 3.4%, P < 0.001).One-year post surgery, less RYGB-patients were lost-to follow-up (12.1% vs 16.5%, P < 0.001) and RYGB resulted in a higher rate of patients with total weight loss of more than 20% (95.8% vs 84.6%, P < 0.001). While the weight-loss after RYGB was similar between hospitals, there was a great variation in weight loss after SG. CONCLUSION This study reflects the pragmatic use and short-term outcome of RYGB and SG in 3 countries in North-Western Europe. Both procedures were safe, with RYGB having higher weight loss and follow-up rates at the cost of a slightly higher 30-day readmission rate.

Abstract
This study has analyzed results from registry-based population studies to assess the effect of bariatric surgery upon cancer incidence at a population level. Relevant studies were identified and meta-analysis was used to calculate pooled odds ratios (POR) for the incidence of cancer after bariatric surgery compared to controls. Eight population-based studies were included with 635,642 total patients. Bariatric surgery was associated with a significant reduction in overall cancer incidence (POR = 0.72; 95% CI 0.59 to 0.87; p = 0.0007) and incidence of obesity-related cancer (POR = 0.55; 95% CI 0.31 to 0.96; p = 0.04). Bariatric surgery was also protective for breast cancer development (POR = 0.50; 95% CI 0.25 to 0.99; p = 0.045). Bariatric surgery appears to be associated with a reduction in cancer incidence at a population-based level.

Bariatric surgery, compared to medical treatment, reduces morbidity at all ages but does not reduce mortality in patients aged < 43 years, especially if diabetes mellitus is present: a post hoc analysis of two retrospective cohort studies. Acta Diabetol 2020; 57:323-333. [PMID: 31598798 DOI: 10.1007/s00592-019-01433-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2019] [Accepted: 09/27/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIMS Bariatric surgery (BS) reduces long-term mortality in comparison with medical treatment of obesity. Some studies indicate that this effect is significant for patients above mean age in different cohorts, but not for younger patients. These findings raise the question whether morbid obese patients should undergo BS as soon as possible, or whether patients might undergo surgery later in their life. METHODS We performed a post hoc analysis of two studies; we evaluated surgery-related long-term mortality in: (1) the whole cohort [857 surgery patients (163 diabetes) vs. 2086 controls (512 diabetes)]; (2) patients above mean age [> 43 years, 427 surgery patients (133 diabetes) vs. 1054 controls (392 diabetes)]; (3) patients below mean age [≤ 43 years, 432 surgery patients (30 diabetes) vs. 1032 controls (120 diabetes]. Then, we analyzed age-related long-term mortality in the whole cohort, as well as in surgery patients and in controls. Finally, we analyzed incident diseases (diabetes, cardiovascular disease, and cancer) as a function of surgery versus no-surgery and of mean age. RESULTS Surgery patients, compared with controls receiving standard medical/dietary treatment, had reduced mortality in the whole cohort (HR = 0.45, 95% CI 0.33-0.62, p = 0.001) and in the study group aged > 43 years (HR = 0.39, 95% CI 0.28-0.56, p = 0.001), but not in the study group aged ≤ 43 years (HR = 0.87, 95% CI 0.42-1.80, p = 0.711). Reduced mortality was observed in non-diabetic and diabetic patients aged > 43 years (HR = 0.37, 95% CI 0.23-0.62, p = 0.001 and HR = 0.45, 95% CI 0.27-0.74, p = 0.002, respectively) who underwent bariatric surgery. In contrast, in patients aged ≤ 43 years, no significant protective effect of bariatric surgery appeared in non-diabetic patients (HR = 0.64, 95% CI 0.24-1.71, p = 0.371), and mortality increased, almost significantly, in diabetic patients aged < 43 years (HR = 2.87, 95% CI 0.96-8.56, p = 0.058), and even more in diabetic patients aged 33-43 years; HR = 4.99, 95% CI 1.18-21.09, p = 0.029). As expected, age-related mortality was increased in the whole cohort (HR = 7.23, 95% CI 5.14-10.17, p = 0.001), in non-diabetic and diabetic controls (HR = 8.55, 95% CI 5.77-12.68, p = 0.001, and HR = 3.76, 95% CI 1.97-7.18, p = 0.001, respectively). The effect of aging was slightly reduced in surgery patients (HR = 3.76, 95% CI 1.87-7.58, p = 0.001), while it was not significant in diabetic surgery patients (HR = 0.70, 95% CI 0.26-1.90, p = 0.88), further emphasizing that diabetes per se has a strong negative effect on survival, also with concomitant bariatric surgery. In a supplementary analysis, HRs did not change when surgery and control parents were matched for the presence of diabetes. Incident diseases (cardiovascular, diabetes, and cancer) were less frequent in surgery than in control patients, irrespective of age. CONCLUSION Bariatric surgery reduces long-term mortality in comparison with medical treatment when performed in patients aged > 43 years, but not in younger patients, where it is neutral or could even increase mortality; reduction in morbidity occurs at any age.

Abstract
BACKGROUND Bariatric surgery is endorsed by multiple societies as the most effective treatment for obesity. Psychosocial functioning has also been noted to improve for most patients after bariatric surgery. However, some studies have shown an increase in post-operative suicide risk. The aim of this study was to review the published literature and evaluate the association of bariatric surgery with suicide events and suicide/self-harm attempts in patients who have undergone weight loss surgery. METHODS MEDLINE and Embase were searched from inception through January 2018 for retrospective or prospective studies reporting mortality outcomes and self-harm or suicide rates after bariatric procedures. The primary outcome was the pooled event rate with 95% confidence interval (95% CI) for suicide. Secondary outcomes were suicide/self-harm attempts after bariatric surgery compared to same population prior to surgery and to matched control subjects, with the respective calculated odds ratios (OR) and 95% CI. RESULTS From 227 citations, 32 studies with 148,643 subjects were eligible for inclusion. The patients were predominantly females (76.9%). Roux-en-Y gastric bypass (RYGB) was the most commonly performed procedure (58.9%). The post-bariatric suicide event rate was 2.7/1000 patients (95% CI 0.0019-0.0038), while the suicide/self-harm attempt event rate was 17/1000 patients (95% CI 0.01-0.03). The self-harm/suicide attempt risk was higher after bariatric surgery within the same population with OR of 1.9 (95% CI 1.23-2.95), and compared to matched control subjects, OR 3.8 (95% CI, 2.19-6.59). CONCLUSIONS Post-bariatric surgery patients had higher self-harm/suicide attempt risk compared to age-, sex-, and BMI-matched controls. Various pre- and post-surgical psychosocial, pharmacokinetic, physiologic, and medical factors may be involved.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a major national and international health burden. It is one of the most common liver diseases worldwide and the most common cause of abnormal liver enzymes in many developed countries. Non-alcoholic fatty liver disease is also known as an important cause of cryptogenic cirrhosis and second leading cause for liver transplantation. It is commonly associated with metabolic syndrome. Non-alcoholic steatohepatitis (NASH) is the progressive phenotype of NAFLD. In spite of promising performance of non-invasive tools, liver biopsy remains the gold standard test for NASH diagnosis. Over decades, many drugs have been investigated in phase 2 and 3; however, no approved therapy to date. Despite the alarming global rates of NAFLD, there are no local community-based studies on the prevalence of NAFLD or local practice guidelines on its management; this expert review aims to fill this gap.

Abstract
BACKGROUND Although bariatric surgery (BS) is considered safe, concern remains regarding severe post-operative adverse events and mortality. Using a national BS registry, the aim of this study was to assess the incidence, etiologies, and risk factors for mortality following BS. METHODS Prospective data from the National Registry of Bariatric Surgery in Israel (NRBS) including age, gender, BMI, comorbidities, and surgical procedure information were collected for all patients who underwent BS in Israel between June 2013 and June 2016. The primary study outcome was the 3.5-year post-BS mortality rate, obtained by cross-referencing with the Israel population registry. RESULTS Of the 28,755 patients analyzed (67.3% females, mean age 42.0 ± 12.5 years, and preoperative BMI 42.14 ± 5.21 kg/m2), 76% underwent sleeve gastrectomy (SG), 99.1% of the surgeries were performed laparoscopically, and 50.8% of the surgeries were performed in private medical centers. Overall, 95 deaths occurred during the study period (146.9/100,000 person years). The 30-day rate of post-operative mortality was 0.04% (n = 12). Male gender (HR = 1.94, 95%CI 1.16-3.25), age (HR = 1.06, 95%CI 1.04-1.09), BMI (HR = 1.08, 95%CI 1.05-1.11), and depression (HR = 2.38, 95%CI 1.25-4.52) were independently associated with an increased risk of all-cause 3.5-year mortality, while married status (HR = 0.43, 95%CI 0.26-0.71) was associated with a decreased risk. CONCLUSION Mortality after BS is low. Nevertheless, a variety of risk factors including male gender, advanced age, unmarried status, higher BMI, and preoperative depressive disorder were associated with higher mortality rates. Special attention should be given to these "at-risk" BS patients.

Abstract
INTRODUCTION The worldwide prevalence of obesity and type 2 diabetes (T2D) constitutes an epidemic that is a threat to public health. Bariatric surgery, including Roux en-Y gastric bypass (RYGB), is currently the most effective treatment to induce long-term weight loss and remission of co-morbid conditions. Surgery, however, comes with an added risk of complications, highlighting the need to understand the comparative effectiveness and risks of surgical versus conventional approaches to the treatment of obesity and T2D. AREAS COVERED Positive and negative outcomes of RYGB surgery in patients with T2D are assessed, with a primary focus on RYGB surgery versus standard non-surgical treatment of obese patients with T2D in randomized clinical trials or high-quality observational cohorts. Searches were conducted in the PubMed database up to 11 April 2019 for relevant studies. EXPERT OPINION High-level evidence reveals that RYGB ameliorates the clinical manifestations of T2D to a significantly higher degree than medical therapy. Postoperative incidence of beneficial effects and complications, however, differ across subgroups of patients with different preoperative characteristics. Key knowledge gaps, particularly on long-term complications, microvascular- and macrovascular events, and mortality should be addressed, so treatment with RYGB can be applied in an individualized approach to maximize benefits and minimize complications.

Roux-en-Y gastric bypass in rat reduces mu-opioid receptor levels in brain regions associated with stress and energy regulation. PLoS One 2019; 14:e0218680.

Abstract
Roux-en-Y gastric bypass surgery (RYGB) is the most common and effective weight loss procedure for severe obesity. However, a significant increase in addictive behaviors and new-onset substance use disorder (SUD) are sometimes observed post-surgery. The endogenous opioid system is known to play a major role in motivated behavior and reward, as well as the abuse of substances, including alcohol, tobacco, opioids and highly palatable foods. Here, we examined the effects of RYGB on mu-opioid receptor levels in the brain. Male Sprague-Dawley rats were assigned to one of four groups: standard diet with sham surgery (control), ad libitum high-energy high-fat (HF) diet with sham surgery, calorie restricted HF diet with sham surgery (Sham-FR), or HF diet with RYGB surgery. Control and HF groups were fed their respective diets for 8 weeks, with surgery performed on the eighth week. After 9 weeks on their respective diets post-surgery, animals were sacrificed for mu-opioid receptor autoradiography using the [3H] [D-Ala2,N-Me-Phe4-Gly5-ol]- enkephalin (DAMGO) ligand. Rats with RYGB showed reduced DAMGO binding in the central amygdala compared to sham-operated HF diet controls, and in the hypothalamus compared to high-fat fed Sham-FR. Diet alone did not change [3H] DAMGO binding in any region. These findings show that RYGB surgery, independent of diet or caloric restriction, decreases mu opioid signaling in specific regions important for stress and energy regulation. Thus, RYGB surgery may lead to greater stress sensitivity via downregulated mu opioid signaling in the central amygdala, which may contribute to the observed increased risk in some subjects for addictive behavior.

Abstract
Postprandial hyperinsulinemic hypoglycemia is an uncommon yet well-established complication of Roux-en-Y gastric bypass (RYGB) that can result in serious morbidity and adversely affect quality of life. It is often unrecognized and may be difficult to diagnose. Management is challenging. As the number of bariatric procedures increases in parallel with the obesity epidemic, clinicians will be tasked to offer effective medical therapies for this complication. Two patients presented several years after RYGB with severe postprandial hypoglycemia. In one of the patients, we were able to document simultaneous postprandial hypoglycemia and hyperinsulinemia. Conventional treatment approaches, including medical nutrition therapy, acarbose, diazoxide, and octreotide, were either ineffective or limited by poor tolerance. Nifedipine and verapamil were used adjunctively with dietary modification, resulting in resolution of symptomatic hypoglycemic episodes. These agents are therapeutic options that can be used for some patients refractory to more traditional treatments. They should be tried before surgical procedures are considered for affected patients. These two cases demonstrate that calcium channel blockers may be efficacious and appropriate for select patients refractory to dietary interventions alone.

Abstract
BACKGROUND It is unclear whether bariatric surgery affects the risk of drug- and alcohol-related mortality. OBJECTIVES To compare the observed drug- and alcohol-related mortality rate with age, sex, race, and year-adjusted rates from the general U.S. POPULATION SETTING The Longitudinal Assessment of Bariatric Surgery-2, a prospective cohort study of 2458 adults who underwent bariatric surgery at 10 U.S. hospitals between April 2006 and April 2009. METHODS Participants attended presurgery and annual postsurgery assessments for up to 7 years. Drug- and alcohol-related standardized mortality ratios (SMR) comparing the observed post-bariatric surgery mortality rate with the age, sex, race, and year-adjusted expected mortality rate from the general U.S. population, among the entire cohort, and among those who underwent Roux-en-Y gastric bypass (RYGB). RESULTS Ten deaths related to drug or alcohol use (6 accidental overdose, 1 intentional overdose, 1 intent unknown overdose, and 2 alcoholic liver disease) occurred across 15,616 person-years of follow-up, all among participants who underwent RYGB (n = 1770). The observed mortality rate was significantly higher than expected for all drug- and alcohol-related causes overall (SMR = 2.10, 95% confidence interval = 1.01-3.86, P = .03) and among participants who underwent RYGB (SMR = 2.90, 95% confidence interval = 1.39-5.33, P = .003). The RYGB SMRs were significant for all overdoses (P = .002) and accidental overdoses (P = .01) and in the same direction but nonsignificant for intentional overdoses, intent unknown overdoses, and alcoholic liver disease (P for all ≥. 05). CONCLUSIONS Drug- and alcohol-related mortality is significantly higher than expected in the 7 years after bariatric surgery, specifically after RYGB.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is increasingly recognized as a significant liver disease, and it covers the disease spectrum from simple steatosis with a risk of development of non-alcoholic steatohepatitis (NASH) to fibrosis, subsequent cirrhosis, end-stage liver failure, and liver cancer with a potential need for liver transplantation. NAFLD and NASH are closely related to obesity, metabolic syndrome, and type 2 diabetes (T2D). The role of gut hormones, especially glucagon-like peptide 1 (GLP-1), is important in NAFLD. Bariatric surgery has the potential for inducing great weight loss and may improve the symptoms of metabolic syndrome and T2D. Recent data demonstrated significant effects of bariatric surgery on GLP-1 and other gut hormones and important lipid metabolic and inflammatory abnormalities in the pathophysiology of NAFLD. Therefore, bariatric surgery may reverse the pathological liver changes in NAFLD and NASH patients. In the present review, we describe NAFLD and NASH pathophysiology and the primary effects of bariatric surgery on metabolic pathways. We performed a systematic review of the beneficial and harmful effects and focused on changes in liver disease severity in NAFLD and NASH patients. The specific focus was liver histopathology as assessed by the invasive liver biopsy. Additionally, we reviewed several non-invasive methods used for the assessment of liver disease severity following bariatric surgery.

Abstract
BACKGROUND Past research suggests self-harm/suicidality are more common among adults who have undergone bariatric surgery than the general population. OBJECTIVES To compare prevalence of self-harm/suicidal ideation over time and identify presurgery risk factors for postsurgery self-harm/suicidal ideation. SETTING The Longitudinal Assessment of Bariatric Surgery-2 is a cohort study with presurgery and annual postsurgery assessments conducted at 10 U.S. hospitals. METHODS Adults with severe obesity undergoing bariatric surgery between March 2006 and April 2009 (n = 2458). Five-year follow-up is reported. Self-reported history of suicidality assessed retrospectively via the Suicide Behavior Questionnaire-Revised (SBQ-R) and self-reported self-harm/suicidal ideation assessed prospectively via the Beck Depression Inventory-Version 1 (BDI-1). RESULTS The SBQ-R was completed by 1540 participants; 2217 completed the BDI-1 pre- and postsurgery. Over 75% of participants were female, with a median age of 46 years and body mass index of 45.9 kg/m2. Approximately one fourth of participants (395/1534) reported a presurgery history of suicidal thoughts or behavior (SBQ-R). The prevalence of self-harm/suicidal ideation (BDI-1) was 5.3% (95% confidence interval [CI], 3.7-6.8) presurgery and 3.8% (95% CI, 2.5-5.1) at year 1 postsurgery (P = .06). Prevalence increased over time postsurgery to 6.6% (95% CI, 4.6-8.6) at year 5 (P = .001) but was not significantly different than presurgery (P = .12). CONCLUSIONS A large cohort of adults with severe obesity who underwent bariatric surgery had a prevalence of self-harm/suicidal ideation that may have decreased in the first postoperative year but increased over time to presurgery levels, suggesting screening for self-harm/suicidality is warranted throughout long-term postoperative care. Several risk factors were identified that may help with enhanced monitoring.

Long-term mortality in obese subjects undergoing malabsorptive surgery (biliopancreatic diversion and biliointestinal bypass) versus medical treatment. Int J Obes (Lond) 2018; 43:1147-1153. [PMID: 30470806 DOI: 10.1038/s41366-018-0244-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 07/25/2018] [Accepted: 07/30/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND AND AIM Aim of this study was to analyze long-term mortality in obese patients receiving malabsorptive bariatric surgery (BS)[biliopancreatic diversion (BPD) and biliointestinal bypass (BIBP)] in comparison to medical treatment of obesity. PATIENTS AND METHODS Medical records of 1877 obese patients [body mass index (BMI) > 35 kg/m2, aged 18-65 years, undergoing BS (n = 472, 111 with diabetes) or non-surgical medical treatment (n = 1405, 385 with diabetes), during the period 1999-2008 (visit 1)] were collected; non-surgical patients were matched for age, sex, BMI, and blood pressure, and life status and causes of death were ascertained through December 2016. Survival was compared across surgery patients and non-surgical patients using Kaplan-Meier plots and Cox regression analyses. RESULTS Observation period was 12.1 ± 3.41 years (mean ± SD). Compared to non-surgical patients, BS patients had reduced all-cause mortality (34/472 (7.2%) vs 181/1,405 (12.9%) patients, χ2 = 11.25, p = 0.001; HR = 0.64, 95% C.I. 0.43-0.93, p = 0.019). Cardiovascular and cancer causes of death were significantly less frequent in surgery vs no-surgery (HR = 0.26, 95% C.I. 0.09-0.72, p = 0.003; HR = 0.21, 95% C.I. 0.09-0.45, p < 0.001, respectively). CONCLUSION Patients who have undergone BPD and BIBP have lower long-term all-cause, cardiovascular-caused and cancer-caused mortality compared to non-surgical medical weight-loss treatment patients. Malabsorptive bariatric surgery significantly reduces long-term mortality in severely obese patients.

Abstract
INTRODUCTION Prior meta-analysis has reported mortality rates among post-operative bariatric patients, but they have not considered psychiatric factors like suicide contributing to mortality. OBJECTIVES The current meta-analysis aims to determine the pooled prevalence for mortality and suicide amongst cohorts using reported suicides post bariatric surgery. It is also the aim of the current meta-analytical study to determine moderators that could account for the heterogeneity found. RESULTS In our study, the pooled prevalence of mortality in the studies which reported suicidal mortality was 1.8% and the prevalence of suicide was 0.3%. Mean body mass index (BMI) and the duration of follow-up appear to be significant moderators. CONCLUSIONS Given the prevalence of suicide post bariatric surgery, it is highly important for bariatric teams to consider both the medical and psychiatric well-being of individuals pre- and post-operatively.

Abstract
Obesity increases risk of falling, but the effect of bariatric surgery on fall-related injuries is unknown. The aim of this study was therefore to study the association between bariatric surgery and long-term incidence of fall-related injuries in the prospective, controlled Swedish Obese Subjects study. At inclusion, body mass index was ≥ 34 kg/m2 in men and ≥38 kg/m2 in women. The surgery per-protocol group (n = 2007) underwent gastric bypass (n = 266), banding (n = 376), or vertical banded gastroplasty (n = 1365), and controls (n = 2040) received usual care. At the time of analysis (31 December 2013), median follow-up was 19 years (maximal 26 years). Fall-related injuries requiring hospital treatment were captured using data from the Swedish National Patient Register. During follow-up, there were 617 first-time fall-related injuries in the surgery group and 513 in the control group (adjusted hazard ratio 1.21, 95% CI, 1.07-1.36; P = 0.002). The incidence differed between treatment groups (P < 0.001, log-rank test) and was higher after gastric bypass than after usual care, banding and vertical banded gastroplasty (adjusted hazard ratio 0.50-0.52, P < 0.001 for all three comparisons). In conclusion, gastric bypass surgery was associated with increased risk of serious fall-related injury requiring hospital treatment.

Abstract
AIM To evaluate the efficacy, pharmacokinetic (PK) profile and tolerability of subcutaneous (s.c.). exendin 9-39 (Ex-9) injection in patients with post-bariatric hypoglycaemia (PBH). METHODS Nine women who had recurrent symptomatic hypoglycaemia after undergoing Roux-en-Y gastric bypass were enrolled in this 2-part, single-blind, single-ascending-dose study. In Part 1, a single participant underwent equimolar low-dose intravenous (i.v.) vs s.c. Ex-9 administration; in Part 2, 8 participants were administered single ascending doses of s.c. Ex-9 during an oral glucose tolerance test (OGTT). Glycaemic, hormonal, PK and symptomatic responses were compared with those obtained during the baseline OGTT. RESULTS Although an exposure-response relationship was observed, all doses effectively prevented hyperinsulinaemic hypoglycaemia and improved associated symptoms. On average, the postprandial glucose nadir was increased by 66%, peak insulin was reduced by 57%, and neuroglycopenic symptoms were reduced by 80%. All doses were well tolerated with no treatment-emergent adverse events observed. CONCLUSIONS Injection s.c. of Ex-9 appears to represent a safe, effective and targeted therapeutic approach for treatment of PBH. Further investigation involving multiple doses with chronic dosing is warranted.

[PMID: 29678347 DOI: 10.1016/j.soard.2018.01.028] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Revised: 01/12/2018] [Accepted: 01/19/2018] [Indexed: 10/18/2022]
Abstract
BACKGROUND Hypoglycemia after bariatric surgery is an increasingly recognized metabolic complication associated with exaggerated secretion of insulin and gut hormones. OBJECTIVE We sought to determine the incidence of hypoglycemic symptoms (hypo-sx) after bariatric surgery and characteristics of those affected compared with those unaffected. SETTING University hospital. METHODS We collected retrospective survey data from the patients who underwent bariatric surgery at a single center. Based on number and severity of postprandial hypo-sx in Edinburgh hypoglycemia questionnaire postoperatively, patients without preoperative hypo-sx were grouped into high versus low suspicion for hypoglycemia. We used multivariable logistic regression to examine potential baseline and operative risk factors for the development of hypo-sx after surgery. RESULTS Among the 1119 patients who had undergone bariatric surgery who received the questionnaire, 464 (40.6%) responded. Among the 341 respondents without preexisting hypo-sx, 29% (n = 99) had new-onset hypo-sx, and most were severe cases (n = 92) with neuroglycopenic symptoms. Compared with the low suspicion group, the high suspicion group consisted of more female patients, younger patients, patients without diabetes, and those who underwent Roux-en-Y gastric bypass with a longer time since surgery and more weight loss. In multivariate analysis, factors independently associated with incidence of hypo-sx after bariatric surgery were female sex (P = .003), Roux-en-Y gastric bypass (P = .001), and absence of preexisting diabetes (P = .011). CONCLUSIONS New onset postprandial hypoglycemic symptoms after bariatric surgery are common, affecting up to a third of those who underwent bariatric surgery. Many affected individuals reported neuroglycopenic symptoms and were more likely to be female and nondiabetic and to have undergone Roux-en-Y gastric bypass.

Obes Facts 2018; 11:109-115. [PMID: 29631270 PMCID: PMC5981630 DOI: 10.1159/000486484] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2017] [Accepted: 12/11/2017] [Indexed: 01/24/2023] Open
Abstract
OBJECTIVE The study aimed at investigating the lifetime prevalence of 22 self-harm behaviors in bariatric surgery candidates (pre-bariatric surgery group; PSG) compared to community controls with obesity (obese community group; OCG). METHODS The Self-Harm Inventory (SHI) was administered to the PSG (n = 139, BMI ≥ 35 kg/m2) and to the OCG (n = 122, BMI ≥ 35 kg/m2). RESULTS Group comparison of cumulative SHI scores indicated a trend towards less endorsed SHI items in the PSG compared to the OCG (medianPSG = 1.00, IQRPSG = 2.00, medianOCG = 1.00, IQROCG = 2.25, U = 7.241, p = 0.033, η2 = 0.02). No significant group differences were found with regard to the rate of suicide attempts (12.4% vs. 9.4% for OCG vs. PSG). At least one type of lifetime self-harm behavior was admitted by 51.8% of the PSG and 63.9% of the OCG (χ2(1) = 3.91, p = 0.048). The results of logistic regressions using Firth's bias reduction method with at least one SHI item endorsed as dependent variable, group as categorical predictor (PSG as baseline), and age or BMI or PHQ-4 as continuous control variable indicated that only PHQ-4 had a positive effect on the odds ratio. CONCLUSION The results suggest that self-harm (including suicidal attempts) is not more prevalent in bariatric surgery candidates than in community control participants with obesity. Further studies are needed to investigate self-harm in bariatric surgery patients, prior and following surgery, compared to non-operated patients with obesity.

All-Cause and Specific-Cause Mortality Risk After Roux-en-Y Gastric Bypass in Patients With and Without Diabetes. Diabetes Care 2017; 40:1379-1385. [PMID: 28760742 PMCID: PMC5606311 DOI: 10.2337/dc17-0519] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2017] [Accepted: 07/09/2017] [Indexed: 02/03/2023]
Abstract
OBJECTIVE This study assessed all-cause and specific-cause mortality after Roux-en-Y gastric bypass (RYGB) and in matched control subjects, stratified by diabetes status. RESEARCH DESIGN AND METHODS RYGB patients were matched by age, BMI, sex, and diabetes status at time of surgery to nonsurgical control subjects using data from the electronic health record. Kaplan-Meier curves and Cox regression were used to assess differences in all-cause and specific-cause mortality between RYGB patients and control subjects with and without diabetes. RESULTS Of the 3,242 eligible RYGB patients enrolled from January 2004 to December 2015, control subjects were identified for 2,428 (n = 625 with diabetes and n = 1,803 without diabetes). Median postoperative follow-up was 5.8 years for patients with diabetes and 6.7 years for patients without diabetes. All-cause mortality was reduced in RYGB patients compared with control subjects only for those with diabetes at the time of surgery (adjusted hazard ratio 0.44; P < 0.0001). Mortality was not significantly improved in RYGB patients without diabetes compared with control subjects without diabetes (adjusted hazard ratio 0.84; P = 0.37). Deaths from cardiovascular diseases (P = 0.011), respiratory conditions (P = 0.017), and diabetes P = 0.011) were more frequent in control subjects with diabetes than in RYGB patients with diabetes. RYGB patients without diabetes were less likely to die of cancer (P = 0.0038) and respiratory diseases (P = 0.046) than control subjects without diabetes but were at higher risk of death from external causes (P = 0.012), including intentional self-harm (P = 0.025), than control subjects without diabetes. CONCLUSIONS All-cause mortality benefits of RYGB are driven predominantly by patients with diabetes at the time of surgery. RYGB patients with diabetes were less likely to die of cardiovascular diseases, diabetes, and respiratory conditions than their counterparts without RYGB.
