Roux-en-Y gastric bypass (RYGB) and duodenal jejunal bypass (DJB), two different forms of bariatric surgery, are associated with improved glucose tolerance, but it is not clear whether the gut microbiota contributes to this effect. Here we used fa/fa rats as a model of impaired glucose tolerance to investigate whether (i) the microbiota varies between fa/fa and nondiabetic fa/+ rats; (ii) the microbiota of fa/fa rats is affected by RYGB and/or DJB; and (iii) surgically induced microbiota alterations contribute to glucose metabolism...

Gastrointestinal bleeding following Roux-en- Y gastric bypass (RYGB) is rare. We report an unusual cause of upper gastrointestinal bleeding following RYGB that was complicated by porto- splenic vein thrombosis. A 35- year- old woman was successfully treated by mesocaval surgical shunt for recurrent variceal hemorrhage in the excluded stomach following RYGB.

Importance: Following the US Food and Drug Administration approval for laparoscopic gastric band surgery in 2001, as many as 96 000 devices have been placed annually. The reported rates of reoperation range from 4% to 60% in short-term studies; however, to our knowledge, few long-term population-level data on outcomes or expenditures are known. Objective: To describe the rate of device-related reoperations occurring after laparoscopic gastric band surgery as well as the associated payments in a longitudinal national cohort...

AIMS: Severe postprandial hypoglycemia with neuroglycopenia is an increasingly recognized, debilitating complication of Roux-en-Y gastric bypass (RYGB) surgery. Increased secretion of insulin and incretin hormones is implicated in its pathogenesis. Histopathologic examination of pancreas has demonstrated increased islet size and/or nuclear diameter in post-RYGB patients who underwent pancreatectomy for severe refractory hypoglycemia with neuroglycopenia (RYGB + NG). We aimed to determine whether β-cell proliferation or apoptosis is altered in RYGB + NG...

BACKGROUND: Obesity leads to olfaction alterations, and this can further impact food choices, appetite, and nutritional status. Bariatric procedures induce weight loss and change in taste and smell perception, but more information is needed, especially using objective olfaction tests. METHODS: A prospective study was conducted during 6 months, with candidates to laparoscopic gastric bypass at a single institution. A preoperative nasofibroscopy and gross smell identification test (The Pocket Smell Test ®) were performed in those meeting the inclusion criteria...

BACKGROUND: Elevated apolipoprotein C-III (apoC-III) has been postulated to contribute to the atherogenic dyslipidemia seen in obesity and insulin-resistant states, mainly by impairing plasma triglyceride-rich lipoprotein (TRL) metabolism. Bariatric surgery is associated with improvements of several obesity-associated metabolic abnormalities, including a reduction in plasma triglycerides (TGs) and an increase in plasma high-density lipoprotein cholesterol (HDL-C). OBJECTIVES: We investigated the specific effect of bariatric surgery on apoC-III concentrations in plasma, non-HDL, and HDL fractions in relation to lipid profile parameters evolution...

BACKGROUND: Patients undergoing gastric bypass (RYGB) surgery require follow-up for efficacy assessment, early detection of postoperative complications, and also for management of co-morbid conditions. Recent literature shows support for improved long-term weight loss with close patient follow-up. However, attrition rates after RYGB have been reported as high as 50%. OBJECTIVE: The objective of this study was to assess the relationship between complete follow-up and improvement or remission of co-morbid conditions at 12 months after surgery...

OBJECTIVE: Roux-en-Y gastric bypass (RYGB) surgery reduces appetite and stimulates new onset alcohol misuse; however, the genesis of these behavioral changes is unclear. This study is hypothesized that new onset alcohol intake is a behavioral adaptation that occurs secondary to reduced appetite and correlates with altered central ghrelin signaling. METHODS: Hedonic high-fat diet (HFD) intake was evaluated prior to the assessment of alcohol intake behaviors in RYGB and control rats...

BACKGROUND: Obesity is a relative contraindication to organ transplantation. Preliminary reports suggest that bariatric surgery may be used as a bridge to transplantation in patients who are not eligible for transplantation because of morbid obesity. SETTING: The Bariatric Center at Tampa General Hospital, University of South Florida, Tampa, Florida. METHODS: We reviewed the outcomes of 16 consecutive patients on hemodialysis for end-stage renal disease (ESRD) who underwent bariatric surgery from 1998 to 2016...

BACKGROUND: Prior studies have suggested less weight loss among African American compared to Caucasian patients; however, few studies have been able to simultaneously account for baseline differences in other demographic, clinical, or behavioral factors. METHODS: We interviewed patients at two weight loss surgery (WLS) centers and conducted chart reviews before and after WLS. We compared weight loss post-WLS by race/ethnicity and examined baseline demographic, clinical (BMI, comorbidities, quality of life), and behavioral (eating behavior, physical activity level, alcohol intake) factors that might explain observed racial differences in weight loss at 1 and 2 years after WLS...

Background: Bariatric surgery is deemed one of the most effective procedures for the treatment of obesity and it aims at the reduction and maintenance of weight loss in long term, as the control of the related comorbidities. Aim: Quantify the occurrence of alterations of the gastrointestinal tract, suggestive signs of nutritional deficiencies and the use of supplements in a group of women undergoing bariatric surgery. Methods: The sample consisted of women aged 20-65 years submitted to Roux-en-Y gastric bypass with monitoring equal to or higher than 24 months...

Contractile activity (e.g. exercise) evokes numerous metabolic adaptations in human skeletal muscle including enhanced insulin action and substrate oxidation. However, there is inter-subject variation in the physiological responses to exercise, which may be linked with factors such as the degree of obesity. Roux-en-Y gastric bypass (RYGB) surgery reduces body mass in severely obese (BMI > 40 kg/m(2)) individuals; however, it is uncertain whether RYGB can potentiate responses to contractile activity in this potentially exercise-resistant population...

OBJECTIVE: This study sought to explore the relationship of bariatric surgeon age and patient outcomes. BACKGROUND: Regulators, policy makers, and patient advocacy groups have recently been pushing to establish clear guidelines for physician retirement in the United States. Although it is often assumed that increasing physician age leads to worse patient outcomes, the relationship is lacking robust evidence, and is still unclear. METHODS: We conducted a study analyzing all bariatric surgeons in Michigan who participated in a statewide collaborative quality improvement program (n = 71) who performed primary laparoscopic Roux-en-Y Gastric Bypass, or sleeve gastrectomy operations, and data on their patients (n = 60430) over the past 10 years...

INTRODUCTION: Laparoscopic adjustable gastric band (LAGB)-related complications have been reported in significant numbers of patients often leading to band removal. Increasingly revisional bariatric surgery (RBS) is offered, most commonly either band to Roux-en-Y gastric bypass (B-RYGB) or band to sleeve gastrectomy (B-SG). OBJECTIVES: We conducted a systematic review and meta-analysis of studies to evaluate the efficacy of RBS following failed LAGB. METHODS: Medline, Embase, The Cochrane Library and NHS Evidence were searched for English language studies assessing patients who had undergone LAGB and who subsequently underwent either B-RYGB or B-SG...
