Pancreas is a preeminent source of ghrelin after sleeve gastrectomy in Wistar rats.

We reported a significant increase of ghrelin epsilon-cells in the pancreas and basal serum after Sleeve gastrectomy versus the control groups. The epsilon cellular increment was related to neogenesis, as the neurogenin-3 marker revealed. The Roux-en Y Gastric Bypass showed neither epsilon cell increase nor basal serum changes in ghrelin release. As a conclusion, we reported that the severe suppression of the fundus gastric produced the recovery of ghrelin released by the epsilon cells, which was indicative of an ontogenic embryonic pancreatic function.

The objective of this study is to look for preoperative predictors of early T2DM relapse/no remission in patients with obesity and diabetes who underwent Roux ‐en‐Y gastric bypass (RYGB) or loop duodeno‐jejunal bypass with sleeve gastrectomy (LDJB‐SG). This is a retrospective study of 113 patients who underwent RYGB or LDJB‐SG for T2DM. All T2DM patients with BMI 27.5 to 37.5 kg/m2, having uncontrolled diabetes and T2DM patients with BMI  >  37.5 were included in the study. A multivariate analysis with a logistic regression model was used for analysed factors. Nineteen patients (16.8%) had early ...

ConclusionsBoth LRYGB and LSG have comparative effect on resolving T2DM in nonseverely obese patients at midterm follow-up. Further RCTs should address the potential risks and long-term effects of LRYGB and LSG in nonseverely obese patients.

Guiding patients with type 2 diabetes mellitus (T2DM) toward the most appropriate bariatric and metabolic procedure is crucial for improving outcomes. In recent years, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) have been the most commonly performed bariatric procedures worldwide. Both are safe, effective, and durable metabolic procedures. The aim of this review is to critically examine the best available evidence derived from the randomized clinical trials (RCTs) to identify which bariatric procedure is superior in an individual with T2DM to provide sustainable long-term remission.

The appropriate selection of patients and surgical procedures is essential for better outcomes after metabolic surgery in patients with type 2 diabetes mellitus (T2DM) and morbid obesity. We validated the usefulness of an individualized metabolic surgery (IMS) score to guide procedure selection based on the severity of T2DM in Koreans.

Abstract Background: Bariatric surgery has been shown to induce type 2 diabetes mellitus (T2DM) remission in severely obese patients. After laparoscopic Roux-en-Y gastric bypass (LRYGB), diabetes remission occurs early and independently of weight loss. Previous research has identified preoperative factors for remission, such as duration of diabetes and HbA1c. Understanding factors that predict diabetes remission can help to select patients who will benefit most from bariatric surgery. Methods: We retrospectively reviewed all T2DM patients who underwent laparoscopic sleeve gastrectomy (LSG) or LRYGB between Ja...

ConclusionWhilst the findings on microvascular complications are encouraging, the rates of metabolic remission were lower than expected and raise the need for validated protocols to assist clinicians in managing these patients more aggressively post-operatively to achieve optimum cardio-metabolic risk factor control and hopefully further reduction in microvascular and macrovascular complications.

AbstractBariatric surgery (BS), including sleeve gastrectomy (SG), gastric bypass (GB), and ileal transposition (IT), is one of the approaches currently used for the correction of metabolic disturbances in type 2 diabetes mellitus (DM2) with obesity. However, the efficiency of these approaches and their impact on hypothalamic signaling and hormonal status in severe forms of DM2 without obesity remain poorly characterized. The aim of this work is to study the effect of IT, SG, and GB on insulin, leptin, ghrelin, and glucagon-like peptide-1 (GLP-1) levels in the blood and on the expression of the genes encoding the main comp...

Conclusions: Bariatric surgery appears to be capable of partially reversing the obesity-related epigenome. The identification of potential epigenetic biomarkers predictive for the success of bariatric surgery may open new doors to personalized therapy for severe obesity. Introduction Obesity is currently a huge healthcare problem, worldwide, and is a risk factor for several diseases such as type 2 diabetes (T2D), cardiovascular disease and cancer (1). As the prevalence of obesity reaches pandemic proportions, this metabolic disease is estimated to become the biggest cause of mortality in the near future (2). In fact,...
