Type 2 diabetes mellitus (T2DM) is a metabolic disorder associated with obesity and hyperglycemia. Roux-en-Y gastric bypass (RYGB) surgery is a common treatment for severely obese patients and T2DM. Both RYGB and T2DM are linked to increased skeletal fragility, though the exact mechanisms are poorly understood. Our aim was to characterize the structural, mechanical and compositional properties of bones from diet-induced obese and RYGB-treated obese (bypass) mice to elucidate which the exact factors are contributing to the increased skeletal fragility...

BACKGROUND: Type 2 diabetes mellitus has a high long-term remission rate after laparoscopic Roux-en-Y gastric bypass (LRYGB), but few studies have analyzed patients with BMI<35 kg/m2. AIM: To compare glycemic control after LRYGB between BMI 30-35 kg/m2 (intervention group or IG) and >35 kg/m2 patients (control group or CG) and to evaluate weight loss, comorbidities and surgical morbidity. METHODS: Sixty-six diabetic patients (30 in IG group and 36 in CG group) were submitted to LRYGB...

Bariatric surgery is an effective treatment for morbid obesity and its metabolic related comorbidities - Type II Diabetes, Hypertension and Hyperlipidaemia.1 However, the literature is scarce regarding the long-term outcome after bariatric surgery especially among multi-ethnic Asian populations. Considering the growing number of bariatric metabolic operations in Asia, we have attempted to provide a regional perspective on 5-year long-term clinical outcomes post bariatric surgery in Singapore. Between years 2010 to 2016, all bariatric operative cases consisted of 393 Laparoscopic Sleeve Gastrectomy (LSG), 125 Laparoscopic Roux-En-Y Gastric Bypass (RYGB) and 43 Laparoscopic Mini-gastric Bypass (MGB) were included...

AIMS/HYPOTHESIS: In this prospective case-control study we tested the hypothesis that, while long-term improvements in insulin sensitivity (SI ) accompanying weight loss after Roux-en-Y gastric bypass (RYGB) would be similar in obese individuals with and without type 2 diabetes mellitus, stimulated-islet-cell insulin responses would differ, increasing (recovering) in those with diabetes but decreasing in those without. We investigated whether these changes would occur in conjunction with favourable alterations in meal-related gut hormone secretion and insulin processing...

INTRODUCTION: Roux-en-Y gastric bypass has been proven to be beneficial for patients with obesity and type 2 diabetes mellitus (T2DM). In less-obese patient (BMI 30-35 kg/m2 ), surgical treatment is indicated when medication fails to control the T2DM. Asian develops diabetes at a lower BMI. For lower-BMI patients, the rate of diabetes amelioration varies significantly with patients of higher BMI after surgical treatment. The factors that contribute to the post-operative diabetes response rate in lower-BMI patients have not been elucidated...

BACKGROUND AND OBJECTIVES: Resistin was originally suggested to be a potential mediator of obesity-related insulin resistance in rodents. However, in humans, the role of resistin in obesity and insulin resistance has not yet been demonstrated. The present study investigates whether there are differences in resistin levels between patients with morbid obesity and lean subjects, and analyzes changes in resistin levels after significant weight loss secondary to bariatric surgery. METHODS: Sixty-eight patients with morbid obesity (body mass index [BMI] ≥ 40 kg/m2) and 31 lean subjects (BMI < 25 kg/m2) were selected...

BACKGROUND: Type 2 diabetes mellitus (T2DM) resolves in >80% of patients after Roux-en-Y gastric bypass (RYGB). It has been hypothesized that foregut exclusion is mechanistically important to this observation. This study aimed to determine whether gastrogastric (GG) fistula, with a loss of foregut exclusion, is associated with T2DM relapse, and to assess whether closure of GG fistula is associated with T2DM resolution. STUDY DESIGN: A matched cohort study of patients who experienced T2DM remission after RYGB...

Objective: To explore partial jejunal diversion (PJD) via a side-to-side jejuno-jejunostomy for improved glycemic control in type 2 diabetes mellitus (T2DM). PJD is an anatomy-sparing, technically simple surgery in comparison to the predominate metabolic procedures, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). Positive results in a rodent model prompted a human proof-of-concept study. Research design and methods: Pre-clinically, 71 rats were studied in a model of metabolic dysfunction induced by a high-fat diet; 33 animals undergoing one of two lengths of PJD were compared with 18 undergoing sham, 10 RYGB and 10 jejuno-ileal bypass...

Therapeutic engineering of glucagon-like peptide 1 (GLP-1) has enabled development of new medicines to treat type 2 diabetes. These injectable analogs achieve robust glycemic control by increasing concentrations of "GLP-1 equivalents" (∼50 pmol/L). Similar levels of endogenous GLP-1 occur after gastric bypass surgery, and mechanistic studies indicate glucose lowering by these procedures is driven by GLP-1. Therefore, because of the remarkable signaling and secretory capacity of the GLP-1 system, we sought to discover mechanisms that increase GLP-1 pharmacologically...

BACKGROUND: Diabetes remission is defined as the return of glycemic control in the absence of medication or insulin use after bariatric surgery. We sought to identify and assess the clinical utility of a predictive model for remission of type 2 diabetes mellitus in a population seeking bariatric surgery. METHOD: A retrospective cohort design was applied to presurgical data on patients referred for Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG)...

Purpose: The mechanism by which bariatric surgery facilitates diabetic control is still unknown. Duodenojejunal bypass supports the foregut theory; however, its efficacy when used alone is not yet established. Methods: During the period from January 2008 to December 2009, patients who underwent laparoscopic duodenojejunal bypass (LDJB) or laparoscopic Roux-en-Y gastric bypass (LRYGB) for type 2 diabetes mellitus (T2DM) with or without morbid obesity were included...

INTRODUCTION: The prevalence of obesity and obesity-related diseases, including type 2 diabetes mellitus (T2DM), is increasing. Exclusion of the foregut, as occurs in Roux-en-Y gastric bypass, has a key role in the metabolic improvements that occur following bariatric surgery, which are independent of weight loss. Endoscopically placed duodenal-jejunal bypass sleeve devices, such as the EndoBarrier (GI Dynamics, Lexington, Massachusetts, USA), have been designed to create an impermeable barrier between chyme exiting the stomach and the mucosa of the duodenum and proximal jejunum...

The present study was a 4-week randomized trial to assess the efficacy and safety of sitagliptin, a dipeptidyl-peptidase-4 inhibitor, in persistent or recurring type 2 diabetes after Roux-en-Y gastric bypass surgery (RYGB). Participants (n = 32) completed a mixed meal test (MMT) and self-monitoring of plasma glucose (SMPG) before and 4 weeks after randomization to either sitagliptin 100 mg daily or placebo daily. Questionnaires were administered to assess gastrointestinal discomfort. Outcome variables were glucose, active glucagon-like peptide-1 and β-cell function during the MMT, and glucose levels during SMPG...

PURPOSE OF REVIEW: Morbid obesity and type-2 diabetes mellitus (T2DM) are both major public health problems. Bariatric surgery is a proven and effective treatment for these conditions; laparoscopic Roux-en-Y gastric bypass (RYGB) is currently the gold-standard treatment. One-anastomosis gastric bypass (OAGB) is described as a simpler, safer, and non-inferior alternative to RYGB to treat morbid obesity. Concerning T2DM, experts of the OAGB procedure report promising metabolic results with good long-term remission of T2DM; however, heterogeneity within the literature prompted us to analyze this issue...

BACKGROUND: Pharmacokinetic data suggest that the risk of metformin-associated lactic acidosis (MALA) may be increased after Roux-en-Y gastric bypass (RYGB) surgery. The aim of this study was to examine the impact of metformin on plasma lactate levels before and after RYGB surgery. METHODS: Retrospective study of plasma lactate levels before and 3 months after RYGB surgery in patients with type 2 diabetes mellitus (T2DM) not using metformin (MET-0, N = 58), on a stable dose (MET-S, N = 138), or on a decreasing dose (MET-D, N = 85) of metformin...

REVIEW
Chelsea R Hutch, Darleen Sandoval
Two of the most popular bariatric procedures, vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB), are commonly considered metabolic surgeries because they are thought to affect metabolism in a weight loss-independent manner. In support of this classification, improvements in glucose homeostasis, insulin sensitivity, and even discontinuation of type 2 diabetes mellitus (T2DM) medication can occur before substantial postoperative weight loss. The mechanisms that underlie this effect are unknown...
