Abstract
While significant weight loss has been observed in the first two years following adjustable gastric banding (AGB), research on the long-term effectiveness of gastric restriction (e.g., 5 years) both on weight loss and eating behavior changes is scarce. The present study examined obese patients' changes in eating behavior preoperatively and 5 years after AGB and examined their associations with excess weight loss (EWL). Specifically, we focused on the association between the modification of three eating behavior profiles (i.e., restrained eating, emotional eating and external eating) and %EWL at 5 years. Among the 197 participants who underwent AGB, 136 completed the clinical assessments (weight, depression with the BDI, eating behavior with the DEBQ) before surgery, and after 5 years. Resultsshowed that the mean percentage of EWL was 47% after 5 years. Moreover, patients reported lower emotional eating and external eating after 5 years in comparison to the baseline, whereas there were no differences concerning restrained eating. Importantly, patients who presented higher %EWL at 5 years also reported a greater decrease in emotional eating between the two sessions than those with low %EWL. Our study underlines that eating behaviors are major variables involved in weight loss after gastric restriction. Results showed that emotional and external eating decreased significantly at 5 years whereas restrained eating behaviors did not vary between the pre- and postoperative stages. Moreover, the data suggest that a decrease in emotional eating accounts for the extent of EWL.

Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery. 2019;(12):2052-2059
Abstract
BACKGROUND Few randomized trials have compared surgical versus lifestyle and pharmacologic approaches for type 2 diabetes (T2D) patients with mild to moderate obesity. OBJECTIVES This study examined resolution of hyperglycemia (A1C <6.5% and fasting glucose <126 mg/dL) 3 years after randomization to either a laparoscopic adjustable gastric band (LAGB) or 1-year diabetes and weight management (DWM) program. SETTING University medical center, United States. METHODS Forty T2D patients (mean ± SD: age, 51.3 ±10.0 yr; weight 109.5 ± 15.0 kg; body mass index [BMI] 36.5 ± 3.7 kg/m2; HBA1C 8.2% ± 1.2%) were randomized to LAGB (n = 18) or DWM (n = 22). RESULTS At 3 years, 13% of 16 patients in LAGB and 5% of 17 patients in DWM achieved resolution of hyperglycemia (P = .601), with a modestly greater reduction in antidiabetic medications in the surgical group (P = .054). Reductions from baseline in A1C were sustained at 3 years in LAGB (-.82% [95% CI: -1.62 to -.01], P = .046) compared with DWM (+.23% [95% CI: -.57 to 1.03], P = .567). The surgical group had greater weight loss (-12.0 kg [95% CI: -15.9 to -8.1] versus -4.8 [95% CI: -8.6 to -.9], P = .010). HDL-cholesterol increased more after surgery (P = .003), but changes in triglycerides, LDL-cholesterol, and blood pressure did not differ between treatments. Diabetes- and obesity-specific quality of life improved comparably with both therapies. CONCLUSIONS Achievement of American Diabetes Association targets for glucose, lipids, and blood pressure was similar with both treatment strategies. LAGB leads to greater sustained weight loss and higher HDL cholesterol compared with a DWM program. These findings may help guide patients with T2D and obesity when exploring options for diabetes and weight management.

Abstract
Endoscopic bariatric therapies (EBTs) are promising alternatives to conventional surgery for obesity. The aim of this study is to compare efficacy and safety through a systematic review and meta-analysis of the endoscopic gastroplasty techniques versus conservative treatment. We searched MEDLINE, EMBASE, Cochrane CENTRAL, Lilacs/Bireme. Randomized controlled trials (RCTs) enrolling obese patients comparing endoscopic gastroplasty to sham or diet/exercise were considered eligible. Among 6014 records, three RCTs were selected for meta-analysis. The total sample was 459 patients (312 EBTs vs 147 control). Mean total body weight loss in the intervention group (IG) was 4.8% higher than the control group (CG) at 12 months (p = 0.01). The IG responder rate was 44.31% at 12 months. Therefore, the endoscopic gastroplasty is more effective than conservative therapies but do not achieve FDA thresholds.

Abstract
BACKGROUND Our aim was to determine the predictive value of gut hormone changes for the improvement of type 2 diabetes (T2D) following metabolic Roux-en-Y gastric bypass (mRYGB), sleeve gastrectomy (SG), and greater curvature plication (GCP) in a randomized controlled trial. Contradictory results have been obtained regarding the role of gastrointestinal hormones (in particular GLP-1) in beneficial metabolic bariatric surgery outcomes. METHODS Forty-five patients with T2D (mean BMI 39.4 ± 1.9 kg/m2) were randomly assigned to mRYGB, SG, or GCP. Anthropometric and biochemical parameters, fasting concentrations of PYY, ghrelin, glucagon, and area under the curve (AUC) of GLP-1 after a standard meal test were determined prior to and at months 1 and 12 after surgery. RESULTS Twelve months after surgery, total weight loss percentage was higher and HbA1c lower in the mRYGB group than in the SG and GCP groups (-35.2 ± 8.1 and 5.1 ± 0.6% vs. -27.8 ± 5.4 and 6.2 ± 0.8% vs. -20.5 ± 6.8 and 6.6 ± 1.3%; p = 0.007 and p < 0.001, respectively). Moreover, GLP-1 AUC at months 1 and 12 was greater and T2D remission was higher in mRYGB (80 vs. 53.3 vs. 20%, p < 0.001). Insulin treatment (odds ratio (OR) 0.025, p = 0.018) and the increase in GLP-1 AUC from baseline to month 1 (OR 1.021, p = 0.013) were associated with T2D remission. CONCLUSIONS mRYGB achieves a superior rate of weight loss and T2D remission at month 12. Enhanced GLP-1 secretion 1 month after surgery was a determinant of glucose metabolism improvement.

Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery. 2017;(6):1063-1070
Abstract
BACKGROUND The literature is rather mixed regarding the stability and the role of pre- and postoperative problematic eating behaviors (PEBs) on weight outcomes after bariatric surgery. OBJECTIVES To investigate the stability of loss of control (LOC) eating and picking and/or nibbling from pre- to postoperative assessments, and to investigate whether pre- and postoperative PEBs are predictors of different weight loss trajectories. SETTING Central Hospital, University, Portugal. METHODS This longitudinal study assessed LOC eating and picking and/or nibbling before and approximately 2 years after laparoscopic adjustable gastric banding or Roux-en-Y gastric bypass through face-to-face interviews and 2 self-report measures. Weight across follow-up time was retrieved from hospital charts. Of the 130 patients invited to participate in the study, 100 were assessed preoperatively, and of these, 61 were also assessed postoperatively. RESULTS Frequency of PEBs is similar pre- and postoperatively (37.7% and 45.9%, respectively) (McNemar χ2P = .832). Yet, about 40% ceased preoperative PEBs. Those with LOC preoperatively were more likely to develop picking and/or nibbling postoperatively (McNemar χ2P<.05). About 39.5% developed PEBs de novo after surgery. The presence of PEBs postoperatively was a significant predictor of different weight loss trajectories after both laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass. Worse weight loss outcomes were found particularly at 17-20 months postsurgery. Preoperative PEBs were not a significant predictor. CONCLUSIONS Our data do not support the stability of all PEBs across time, highlighting that the absence of preoperative PEBs does not preclude an unfavorable weight loss outcome after surgery. Postoperative but not preoperative PEBs are predictors of poorer weight loss trajectories after surgery.

Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery. 2017;(9):1562-1571
Abstract
BACKGROUND Having accurate information on bariatric surgery-related gastrointestinal (GI) symptoms is critical for patient care. OBJECTIVE To report on surgery-related GI symptoms over the first 3 years following Roux-en-Y gastric bypass and laparoscopic adjustable gastric band. SETTING Three academic medical centers in the United States. METHODS As a substudy of the Longitudinal Assessment of Bariatric Surgery Consortium, 183 participants (pre-surgery median body mass index = 45.1 kg/m2; median age = 46 yr; 83.1% female). completed the Eating Disorder Examination-Bariatric Surgery Version interview at≥1 annual assessment. Patients self-reported frequency of dysphagia, dumping syndrome, and spontaneous vomiting. RESULTS Prevalence of dysphagia at least once weekly decreased post-laparoscopic adjustable gastric band surgery from 43.9% (95% confidence interval [CI], 32.2-55.6) in year 1 to 27.5% (95% CI, 15.2-39.9) in year 3 (P = .02). Dysphagia and dumping at least once weekly also appeared to decrease in years 1-3 post-Roux-en-Y gastric bypass (i.e., from 16.7% [95% CI, 9.4-24.1] to 10.9% [95% CI, 4.0-17.8] and from 9.9% [95% CI, 4.3-15.5] to 6.3% [95% CI, 1.7-10.9], respectively), but power was limited to evaluate trends. Vomiting at least once weekly was rare (<6%) in years 1-3 following both procedures. Controlling for potential confounders and surgical procedure, loss of control eating at least once weekly was associated with higher risk of at least once weekly dysphagia (relative risk = 2.01, 95% CI, 1.36-2.99, P = .001). CONCLUSIONS The prevalence of bariatric surgery-related GI symptoms appears to decrease across follow-up. Symptoms were associated with loss of control eating, suggesting a target for clinical intervention.

Abstract
CONTEXT It is not known whether the magnitude of metabolic adaptation, a greater than expected drop in energy expenditure, depends on the type of bariatric surgery and is associated with cardiometabolic improvements. OBJECTIVE To compare changes in energy expenditure (metabolic chamber) and circulating cardiometabolic markers 8 weeks and 1 year after Roux-en-y bypass (RYGB), sleeve gastrectomy (SG), laparoscopic adjustable gastric band (LAGB), or a low-calorie diet (LCD). Design, Setting, Participants, and Intervention: This was a parallel-arm, prospective observational study of 30 individuals (27 females; mean age, 46 ± 2 years; body mass index, 47.2 ± 1.5 kg/m2) either self-selecting bariatric surgery (five RYGB, nine SG, seven LAGB) or on a LCD (n = 9) intervention (800 kcal/d for 8 weeks, followed by weight maintenance). RESULTS After 1 year, the RYGB and SG groups had similar degrees of body weight loss (33-36%), whereas the LAGB and LCD groups had 16 and 4% weight loss, respectively. After adjusting for changes in body composition, 24-hour energy expenditure was significantly decreased in all treatment groups at 8 weeks (-254 to -82 kcal/d), a drop that only persisted in RYGB (-124 ± 42 kcal/d; P = .002) and SG (-155 ± 118 kcal/d; P = .02) groups at 1 year. The degree of metabolic adaptation (24-hour and sleeping energy expenditure) was not significantly different between the treatment groups at either time-point. Plasma high-density lipoprotein and total and high molecular weight adiponectin were increased, and triglycerides and high-sensitivity C-reactive protein levels were reduced 1 year after RYGB or SG. CONCLUSIONS Metabolic adaptation of approximately 150 kcal/d occurs after RYGB and SG surgery. Future studies are required to examine whether these effects remain beyond 1 year.

Surgical endoscopy. 2016;(6):2186-91
Abstract
BACKGROUND Laparoscopic greater curvature plication (LGCP) is a new restrictive bariatric procedure, which has a similar restrictive mechanism like laparoscopic sleeve gastrectomy (LSG) without potential risk of leak. Aim of the study was to compare 2-year outcomes of LSG and LGCP. METHODS Multicenter prospective randomized trial was started in 2010. A total of 54 patients with morbid obesity were allocated either to LGCP group (n = 25) or LSG group (n = 27). Main exclusion criteria were: ASA > III, age > 75 and BMI > 65 kg/m(2). There were 40 women and 12 men, and the mean age was 42.6 ± 6.8 years (range 35-62). Data on the operation time, complications, hospital stay, body mass index loss, percentage of excess weight loss (%EWL), loss of appetite and improvement in comorbidities were collected during the follow-up examinations. RESULTS All procedures were completed laparoscopically. The mean operative time was 92.0 ± 15 min for LSG and 73 ± 19 min for LGCP (p > 0.05). The mean hospital stay was 4.0 ± 1.9 days in the LSG group and 3.8 ± 1.7 days in LGCP group (p > 0.05). One year after surgery, the mean %EWL was 59.5 ± 15.4 % in LSG group and 45.8 ± 17 % in LGCP group (p > 0.05). After 2 years, mean %EWL was 78.9 ± 20 % in the LSG group and 42.4 ± 18 % in the LGCP group (p < 0.01). After 3 years, mean %EWL was 72.8 ± 22 in the LSG group and only 20.5 ± 23.9 in the LGCP group (p < 0.01). Loss of feeling of hunger after 2 years was 25 % in LGCP group and 76.9 % in the LSG group (p < 0.05). The comorbidities including diabetes, sleep apnea and hypertension were markedly improved in the both groups after surgery. CONCLUSION The short-term outcomes demonstrated equal effectiveness of the both procedures, but 2-year follow-up showed that LGCP is worse than LSG as a restrictive procedure for weight loss.

Changes in problematic and disordered eating after gastric bypass, adjustable gastric banding and vertical sleeve gastrectomy: a systematic review of pre-post studies.
Opozda, M, Chur-Hansen, A, Wittert, G
Obesity reviews : an official journal of the International Association for the Study of Obesity. 2016;(8):770-92
Abstract
Despite differences in their mechanisms and outcomes, little is known about whether postsurgical changes in eating behaviours also differ by bariatric procedure. Following a systematic search, 23 studies on changes in binge eating disorder (BED) and related behaviours, bulimia nervosa and related behaviours, night eating syndrome, grazing and emotional eating after Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB) and vertical sleeve gastrectomy (VSG) were reviewed. Significant methodological problems and a dearth of literature regarding many behaviours and VSG were seen. Regarding BED and related behaviours, although later re-increases were noted, short to medium-term reductions after RYGB were common, and reported changes after AGB were inconsistent. Short to medium-term reductions in emotional eating, and from a few studies, short to long-term reductions in bulimic symptoms, were reported after RYGB. Reoccurrences and new occurrences of problem and disordered eating, especially BED and binge episodes, were apparent after RYGB and AGB. Further conclusions and comparisons could not be made because of limited or low-quality evidence. Long-term comparison studies of changes to problematic and disordered eating in RYGB, AGB and VSG patients are needed. It is currently unclear whether any bariatric procedure leads to long-term improvement of any problematic or disordered eating behaviours.
