Gastric bypass diabetes mellitus type 2

BACKGROUND: Owing to the possibility of weight regain after the long-term follow-up of gastric bypass patients and because of the high morbidity of biliopancreatic diversion with duodenal switch, single-anastomosis duodeno-ileal switch (SADIS) has emerged as a rescue procedure in bariatric surgery. OBJECTIVE: The purpose of this review is to summarize the literature data on SADIS. SETTING: University Hospital, NY. METHODS: A comprehensive literature review was performed through October 2016 to identify English studies on SADIS performed in human subjects...

BACKGROUND: Mild obesity (BMI 30-34.9 kg/m(2)) is highly prevalent worldwide and is associated with type 2 diabetes mellitus. The efficacy of bariatric surgery remains unclear, including among Mexicans. The criteria for diabetes remission are inconsistent, as they are based on different thresholds for glycated hemoglobin, with remission rates ranging from 43 to 73%. METHODS: Mildly obese patients with type 2 diabetes mellitus who underwent laparoscopic gastric bypass were prospectively analyzed...

Bariatric surgery is emerging as a powerful weapon against severe obesity and type 2 diabetes mellitus (T2DM). Given its role in metabolic regulation, the gastrointestinal tract constitutes a meaningful target to treat T2DM, especially in light of accumulating evidence that surgery with gastrointestinal manipulations may result in T2DM remission (metabolic surgery). The major mechanisms mediating the weight loss-independent effects of bariatric surgery comprise effects on tissue-specific insulin sensitivity, β-cell function and incretin responses, changes in bile acid composition and flow, modifications of gut microbiota, intestinal glucose metabolism and increased brown adipose tissue metabolic activity...

BACKGROUND: Diabetes remission is not observed in all obese patients with type 2 diabetes submitted to bariatric surgery. Relapses occur in patients in whom remission is achieved. We investigated the factors associated with long-term (≥3 years) remission and relapse of type 2 diabetes after Roux-en-Y gastric bypass (RYGB) in these patients. METHODS: By a retrospective review, we analyzed data from 254 patients with type 2 diabetes who had undergone RYGB from May 2000 to November 2011 and had at least 3 years of follow-up...

OBJECTIVE: We recently showed that Roux-en-Y gastric bypass (RYGB) reduces risks of mortality, cardiovascular death and myocardial infarction in obese individuals compared with matched patients with diabetes mellitus (DM). We have examined changes in risk factors after RYGB, with the aim of explaining these effects. RESEARCH DESIGN AND METHODS: We matched (1:1) 6132 RYGB patients with DM reported to the Scandinavian Obesity Surgery Register with patients who had not undergone RYGB, based on sex, age, body mass index (BMI) and time, and assessed effects 2007-2014...

INTRODUCTION: Frequent causes of high anion gap metabolic acidosis (HAGMA) are lactic acidosis, ketoacidosis and impaired renal function. In this case report, a HAGMA caused by ketones, L- and D-lactate, acute renal failure as well as 5-oxoproline is discussed. CASE PRESENTATION: A 69-year-old woman was admitted to the emergency department with lowered consciousness, hyperventilation, diarrhoea and vomiting. The patient had suffered uncontrolled type 2 diabetes mellitus, underwent gastric bypass surgery in the past and was chronically treated with high doses of paracetamol and fosfomycin...

- Bariatric surgery is performed in patients with a body mass index (BMI) > 40kg/m2, or BMI > 35 kg/m2 with obesity-related comorbidities. The Roux-en-Y gastric bypass and sleeve gastrectomy are the most frequently used procedures.- On average, patients have lost 25-27% of their original weight 10 years after surgery.- Obesity-related comorbidities improve dramatically in many patients following surgery. The effect is most noticeable in patients with diabetes mellitus type 2 and obstructive sleep apnoea syndrome...

Bariatric surgery is the most effective treatment for obesity with or without type 2 diabetes mellitus and its complications. With the growing incidence of type 2 diabetes mellitus, the number of hospitals performing bariatric surgery and surgical cases increase substantially. The problems in operation standardization, quality control of operation and postoperative management of the patients cause the failure in weight loss, hypoglycemia and severe complications, and revisional surgery is often required to correct the condition...

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...

BACKGROUNDS/OBJECTIVES: The activity of brown/beige adipose tissue is inversely proportional to body adiposity. Studies have shown that obese subjects submitted to distinct approaches aimed at reducing body mass present an increase of brown/beige adipose tissue activation. However, it is unknown if this beneficial effect of body mass reduction applies to patients with type 2 diabetes mellitus. In this study, we evaluated the impact of massive body mass reduction obtained as a consequence of bariatric surgery in the cold-induced activation of brown/beige adipose tissue in obese non-diabetic and obese diabetic subjects...

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...
