Gastric bypass diabetes mellitus type 2

OBJECTIVE: The aim of this study was to compare the cost and health care utilization of patients with obesity and type 2 diabetes mellitus (T2DM) randomized into either Roux-en-Y gastric bypass (RYGB) surgery or an intensive lifestyle and medical intervention (ILMI). METHODS: This analysis (N = 745) is based on 2-year follow-up of a small randomized controlled trial (RCT); adult patients with obesity and T2DM were recruited between 2011 and 2012 from Kaiser Permanente Washington...

Type 2 diabetes mellitus (T2DM) is one of the largest health emergencies of the 21st century given the worldwide increase of obesity during the last decades and its close association. T2DM is an inherited, polygenic and chronic disease caused by the interaction between several genetic variants in genes and the environment. The continuous search for new and more effective tools to achieve appropriate glycemic control became imperative in order to reduce long-term complications and mortality rates related to T2DM...

OBJECTIVE: The underlying causes of type 2 diabetes (T2DM) remain poorly understood. Adipose tissue dysfunction with high leptin, inflammation, and increased oxidative stress may play a pivotal role in T2DM development in obese patients. Little is known about the changes in the adipose tissue after Roux-Y gastric bypass (RYGB) in non-severely obese patients (BMI < 35 kg/m(2)) and since these patients have more T2DM-associated complications than obese patients ("obesity paradox"), we investigated changes in adipose tissue function in a cohort of BMI <35 kg/m(2) with insulin-dependent T2DM after RYGB surgery which resolves T2DM...

Primary bariatric surgery has been proven to be effective in weight loss and improvement of weight-related metabolic co-morbidities. However, a small proportion of patients after bariatric surgery either have persistent hyperglycemia or relapse after initial remission of their metabolic disease. Revisional bariatric surgery has been evaluated extensively for weight recidivism and postoperative complications. However, there has not been any high-level evidence validating the utility of revisional bariatric surgery on recurrent metabolic diseases, especially diabetes...

Obesity increases the risks of metabolic disorders including type 2 diabetes mellitus (T2DM). Bariatric surgery is the most successful therapeutic option that causes sustained weight loss and improvements in obesity comorbidities. Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) are two of the most frequently performed bariatric surgeries. Despite their different anatomical rearrangement, they have remarkably similar success in both weight loss and T2DM remission. Interestingly, they also both cause a wide range of endocrine changes...

The obesity epidemic continues to escalate each year in the United States more than anywhere else in the world. The existing pharmaceutical and other nonsurgical treatments for morbid obesity produce suboptimal physiologic outcomes compared with those of Roux-en-Y gastric bypass (RYGB) surgery. RYGB has been the gold standard of bariatric surgery because the beneficial long-term outcomes, which include sustainable weight loss and type 2 diabetes mellitus (T2DM) resolution, are far superior to those obtained with other bariatric surgeries...

OBJECTIVE: To evaluate the cost-effectiveness of bariatric surgery in Italy from a third-party payer perspective over a medium-term (10 years) and a long-term (lifetime) horizon. METHODS: A state-transition Markov model was developed, in which patients may experience surgery, post-surgery complications, diabetes mellitus type 2, cardiovascular diseases or die. Transition probabilities, costs, and utilities were obtained from the Italian and international literature...

BACKGROUND: The aim of this study was to investigate the relation between the different bariatric surgeries and pancreatic β-cell turnover. MATERIAL AND METHODS: We used healthy adult male Wistar rats to undergo the different techniques. Three surgical techniques were developed (malabsorptive, Sleeve gastrectomy and Roux-Y Gastric Bypass-), together with two control groups (Sham and fasting control). Pancreatic β-cell mass was measured, as well as apoptosis, proliferation and neogenesis related to cellular turnover...

OBJECTIVE: To evaluate the therapeutic effects of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic duodenal-jejunal bypass with sleeve gastrectomy (SADJB-SG) in patients with type 2 diabetes mellitus and a low body mass index (BMI) of 25-27.5. METHODS: Thirty-one type 2 diabetic patients with a BMI of 25-27.5 underwent bariatric surgeries in the General Hospital of Guangzhou Military Command between August, 2013 and August, 2015. The patients receiving LRYGB (17 cases) and SADJB-SG (14 cases) were compared for physical indexes, glucose metabolism and of pancreatic islet function at 1 year after the surgeries...

BACKGROUND: Bariatric surgery is widely accepted as the best treatment for obesity and type 2 diabetes mellitus (T2DM). The Roux-en-Y gastric bypass (RYGB) and the sleeve gastrectomy (SG) have become the predominant bariatric procedures in the USA over the last several years, although the most recent trends in selection are unknown. OBJECTIVE: The objective of this study is to assess selection trends, readmission rates, and cost of bariatric procedures in the USA from 2012 to 2015...

AIM: To compare the impact of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) on weight loss and obesity related comorbidities over two year follow-up via case control study design. METHODS: Forty patients undergoing LRYGB, who completed their two year follow-up were matched with 40 patients undergoing LSG for age, gender, body mass index and presence of type 2 diabetes mellitus (T2DM). Data of these patients was retrospectively reviewed to compare the outcome in terms of weight loss and improvement in comorbidities, i...

INTRODUCTION: 3D laparoscopy allows the surgeon to regain the sense of depth and improve accuracy. The aim of the study was to assess the impact of 3D in bariatric surgery. PATIENTS AND METHODS: A retrospective cohort study was conducted. All our patients who underwent bariatric surgery (sleeve gastrectomy (SG) or gastric bypass (GB)) between 2013 and 2016 were included. We compared 3D laparoscopy cohort and 2D laparoscopy cohort. Variables are as follows: age, sex, DM, hypertension, surgeon experience, and type of intervention...

Through continuous development, metabolic and bariatric surgery (MBS) has become widely recognized in academic and medical circles. In China, the volume of MBS operations has increased year by year. Therapeutic goals of MBS have evolved from treating obesity to treating Type 2 diabetes mellitus, and further to treating a series of obesity-associated metabolic diseases (including conditions in the endocrine system, circulatory system, respiratory system, reproductive system, and etc). Surgical approach of MBS has also been evolving continuously...

Along with the soaring prevalence of obesity and type 2 diabetes mellitus (T2DM) globally, metabolic and bariatric surgery (MBS) has been rapidly developing into a major surgical subspecialty. However, the indications, benefits and potential risks of MBS are still controversial so far. In September 2015, the 2nd Diabetes Surgery Summit (DSS-II() was successfully convened, and later on an international joint statement on metabolic surgery in the treatment algorithm for T2DM was released based upon the consensus reached in DSS-II(, aiming to serve as a new global clinical guideline...

Type 2 diabetes mellitus is becoming increasingly prevalent worldwide and has become one of the greatest threats to global health. Bariatric surgery was initially designed to achieve weight loss and subsequently was noted to induce improvements or remission of type 2 diabetes. Currently, these bariatric operations such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most effective procedures for the treatment of obesity and type 2 diabetes mellitus worldwide. However, the specific mechanism mediating the beneficial effects of metabolic surgery has remained largely unknown...

Roux-en-Y gastric bypass (RYGB) is associated with the remission of type 2 diabetes mellitus (DM). There are a number of scoring systems available that help predict type 2 diabetes remission rates after bariatric surgery; however, relatively few have been validated externally. The DiaRem score, comprised of four preoperative variables (age, haemoglobin A1c [HbA1c], sulfonylurea and insulin-sensitizing agent use and insulin use), allows for the identification of patients who are most likely to have DM remission following RYGB...

BACKGROUND: The promising postsurgical weight loss and remission of type 2 diabetes (T2D) from bariatric surgery can be attributed to modified eating physiology after surgical procedures. We sought to investigate the changes in the parameters of consumption behaviors and appetite sensations induced by a mixed meal tolerance test, and to correlate these alterations with age, body mass index, C-peptide levels, and duration of T2D 1 year after bariatric surgery. METHODS: A total of 16 obese patients with T2D who underwent mini-gastric bypass (GB) and 16 patients who underwent sleeve gastrectomy (SG) were enrolled in this study and evaluated using a mixed meal tolerance test one year after surgery...

Roux-en-Y gastric bypass (RYGB) induces remission or substantial improvement of type 2 diabetes mellitus (T2D) but underlying mechanisms are still unclear. The beneficial effects of dietary proteins on energy and glucose homeostasis are mediated by the antagonist effects of peptides toward mu-opioid receptors (MORs), which are highly expressed in the distal gut. We hypothesized that the beneficial effects of RYGB could depend at least in part on the interaction of peptides from food with intestinal MORs. Duodenal-jejunal bypass (DJB) was performed in obese and lean wild-type (WT) or MOR deficient (MOR(-/-)) mice...

Bariatric surgery is an effective treatment of type 2 diabetes in obese patients. The obesity epidemic does not spare patients with type 1 diabetes mellitus (T1DM), but there is no consensus regarding the role of surgery in the management of obese T1DM patients. Published data consistently report significant weight loss after surgery in obese T1DM patients, but long-term glycaemic control remains difficult to achieve. Here we present our experience with a challenging patient and a review of the literature. Our patient successfully underwent a roux-en-Y gastric bypass (RYGB) when she was 28 years old...
