BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been the "gold standard" for weight loss surgery. Long-term data are limited, and reporting methods for LRYGB outcomes vary in the literature. In addition, follow-up compliance within bariatric centers is poor due to insurance and access to care issues, making long-term follow-up evaluation difficult. OBJECTIVE: Evaluate long-term LRYGB outcomes using standard outcome reporting definitions. SETTING: Integrated multispecialty health system...

Bariatric surgery is currently the most effective strategy in treating severe obesity and its comorbidities, such as type 2 diabetes (T2D). However, the mechanism through which bariatric surgery mediates its benefits is not completely understood. Since obesity and T2D represent yet another inflammatory disease, and follicular helper T (Tfh) cells play important roles in inflammatory disorders, we investigated whether the Tfh activity was altered after Roux-en-Y gastric bypass (RYGB), one of the most common bariatric surgery procedures...

BACKGROUND: Marginal ulcer (MU) is not infrequent after laparoscopic Roux-en-Y gastric bypass (LRYGB). Medication plus lifestyle modification remains the mainstay solution. Patients with refractory MU may be candidates for revisional surgery. OBJECTIVE: To summarize our experience of revisional surgery for treating refractory MU after LRYGB. SETTING: University hospital, Taiwan. METHODS: A retrospective analysis was performed for 11 patients with refractory MU undergoing totally hand-sewn gastrojejunostomy and truncal vagotomy at our institution between August 2005 and May 2015...

BACKGROUND: Intestinal expression of regenerating pancreatic islet-derived protein-encoding genes (REG) would be enhanced after Roux-en-Y gastric bypass (RYGB) and would affect postoperative type 2 diabetes remission (T2Dr). METHODS: Intestinal biopsy samples were collected from 20 adult obese women with T2D before and 3 months after RYGB. Levels of REG expression and the gene encoding its putative receptor (EXTL3) were assessed by microarray and validated by quantitative RT-PCR...

BACKGROUND: Several studies have addressed short-term admission rates after bariatric surgery. However, studies on long-term admission rates are few and population based studies are even scarcer. OBJECTIVE: The aim of this study was to assess short- and long-term admission rates for gastrointestinal surgery after gastric bypass in Sweden compared with admission rates in the general population. SETTING: Swedish healthcare system. METHODS: The surgery cohort consisted of adults with body mass index≥35 identified in the Scandinavian Obesity Surgery Registry (n = 28,331; mean age 41 years; 76% women; Roux-en-Y gastric bypass performed 2007-2012)...

BACKGROUND: Increasingly, patients are faced with greater travel distances to undergo bariatric surgery at high-volume centers. OBJECTIVES: This study sought to evaluate the impact of travel distance on access to care and outcomes after bariatric surgery. SETTING: Patients who underwent Roux-en-Y gastric bypass at an academic bariatric surgery center from 1985 to 2004 were examined and stratified by patient travel distance. METHODS: Univariate analyses were performed for preoperative risk factors, 30-day complications, and long-term (10-yr) weight loss between "local," defined as<1 hour of travel time, and "regional," defined as>1 hour of travel time...

INTRODUCTION: Results of the effects of Roux-en-Y gastric bypass (GB) and sleeve gastrectomy (SG) on triglyceride and high-density lipoprotein (HDL) cholesterol levels are controversial. Moreover, previous meta-analyses focused on global dyslipidaemia remission, but did not include the separate remission rates of the different lipid fractions. Hence, the aim of the present meta-analysis was to compare the outcomes (concentration change and remission rates) of GB and SG on diverse lipid disorders one year post-bariatric surgery (BS)...

BACKGROUND: Internal hernia (IH) is a common complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Little large-volume data exist on how to handle the mesenteric defects during LRYGB. This study evaluated long-term follow-up (5.5 years) of 2443 patients with primary closure of the mesenteric defects with a stapling device at LRYGB, in comparison with a non-closed group from the same centre. METHODS: All patients (N = 4013) undergoing LRYGB over a 10-year period (2005-2015) at a single institution were evaluated...

Postprandial secretion of glucagon-like peptide-1 (GLP-1) is enhanced after Roux-en-Y gastric bypass (RYGB), but the precise molecular mechanisms explaining this remain poorly understood. Plasma concentrations of bile acids (BAs) increase after RYGB, and BAs may act as molecular enhancers of GLP-1 secretion through activation of TGR5-receptors. We aimed to evaluate GLP-1 secretion after oral administration of the primary bile acid chenodeoxycholic acid (CDCA) and the secondary bile acid ursodeoxycholic acid (UDCA) (which are available for oral use) in RYGB-operated participants...

Roux-en-Y gastric bypass (RYGB) induces weight loss and improves insulin sensitivity when evaluated by the hyperinsulinemic-euglycemic clamp (HEC). Surrogate indices of insulin sensitivity calculated from insulin and glucose concentrations at fasting or after an oral glucose tolerance test (OGTT) are frequently used, but have not been validated after RYGB. Our aim was to evaluate whether surrogate indices reliably estimate changes in insulin sensitivity after RYGB. Four fasting (inverse-HOMA-IR, HOMA2-%S, QUICKI, revised-QUICKI) and three OGTT-derived surrogates (Matsuda, Gutt, OGIS) were compared with HEC-estimated peripheral insulin sensitivity (Rd or Rd/I, depending on how the index was originally validated) and the tracer-determined hepatic insulin sensitivity index (HISI) in patients with preoperative type 2 diabetes (n=10) and normal glucose tolerance (n=10) 1 week, 3 months and 1 year postoperatively...

BACKGROUND & AIMS: Roux-en-Y gastric bypass (RYGB) is an effective treatment for obesity. However, it also leads to multiple nutritional deficiencies. Much is known about the short term prevalence, but hardly any long term data is available on deficiencies. The aim of this study was to assess the long term outcome of nutritional status after RYGB. METHODS: We performed a retrospective analysis of prospectively collected data obtained from 51 morbidly obese patients who underwent a primary laparoscopic RYGB...
