BACKGROUND: The positive impact of Roux-en-Y gastric bypass (RYGB) on metabolic syndrome and glycemic control has been proven in obese patients. One anastomosis gastric bypass (OAGB) is a simple, effective and easy to learn procedure. OAGB provides encouraging results for the treatment of diabetes obese patients, but does it have the ability to be an alternative procedure to RYGB in the treatment of these patients? The aim of this study is to evaluate the outcomes of OAGB on diabetic obese patients at the bariatric centre of our university hospital...

BACKGROUND: Empirical evidence suggests Roux-en-Y gastric bypass (RYGB) increases risk of developing alcohol use disorder (AUD). However, prospective assessment of substance use disorders (SUD) after bariatric surgery is limited. OBJECTIVE: To report SUD-related outcomes after RYGB and laparoscopic adjustable gastric banding (LAGB). To identify factors associated with incident SUD-related outcomes. SETTING: 10 U.S. hospitals METHODS: The Longitudinal Assessment of Bariatric Surgery-2 is a prospective cohort study...

BACKGROUND: An increased risk of small-for-gestational-age infants after maternal bariatric surgery has been shown. The risk of micronutrients deficiencies in these neonates is unclear. OBJECTIVE: To screen for micronutrients deficiencies in newborns of mothers with gastric bypass. SETTINGS: University hospital in Angers, France. METHODS: This study compared the clinical and cord blood biological characteristics of 56 newborns of mothers with prior Roux-en-Y gastric bypass (RYGB) and 56 newborns of nonobese healthy mothers after normal pregnancy (controls), followed between January 3, 2008 and October 31, 2012...

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.

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: Morpho-functional modifications of the gastric remnant after Roux-en-Y gastric bypass (RYGB) have not been completely defined, due to its inaccessibility for bioptic mapping. The aim of the study is to evaluate such modifications using Gastropanel®, a non-invasive blood test cross-checking four gastric biomarkers, able to provide a snapshot of mucosa conditions. SUBJECTS AND METHODS: Twenty-four women undergoing RYGB were prospectively enrolled. Gastropanel® parameters (pepsinogens, Gastrin-17 and immunoglobulins against Helicobacter pylori), biometrical/clinical data were collected preoperatively and at 6-months follow-up...

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...

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...

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...

BACKGROUND: Iron deficiency can occur in patients after Roux-en-y gastric bypass due to altered absorption. Pica, the compulsive craving and intake of non-nutritive substances, is a rare and poorly understood presentation of iron deficiency. To our knowledge, the rate of pica after RYGB has never been reported. METHODS: The medical records of patients who underwent laparoscopic RYGB from 2001 to 2011 were reviewed. Patients with pica or other abnormal cravings were identified...

BACKGROUND Over the past few decades, bariatric surgery, especially Roux-en-Y gastric bypass (RYGB), has become widely considered the most effective treatment for morbid obesity. In most cases, it results in enhanced glucose management in patients with obesity and type 2 diabetes (T2D), which is observed before significant weight loss. However, what accounts for this effect remains controversial. To gain insight into the benefits of RYGB in T2D, we investigated changes in the β-cell mass of obese rats following RYGB...

Background Obesity is one of the major challenges of the 21st century. There is also an increasing incidence of obesity in adolescents. Bariatric surgery has been proven safe and effective in obese adults. In adolescents, these operations are still subject to controversy. Current evidence is limited regarding its safety and outcome in this age group. Methods Within the German Bariatric Surgery Registry, data from obese patients that underwent bariatric procedures in Germany are prospectively registered. The current analysis includes all adolescent and adult subjects that underwent primary Roux-Y-gastric bypass (RYGB) surgery from 2005 to 2014...

BACKGROUND: Gastric stenosis (GS) is a potential adverse event post-laparoscopic sleeve gastrectomy (LSG). Endoscopic management is preferred; however, there is significant variation in therapeutic strategies with no defined algorithm. This study aims to describe the safety and efficacy of a predefined step-wise algorithm for endoscopic management of GS post-LSG. METHODS: Consecutive patients with symptomatic GS post-LSG, presenting between July 2015 and August 2016, were subjected to a predefined treatment algorithm of serial dilations using achalasia balloons, followed by a fully covered self-expanding metal stent (FCSEMS) if dilations were inadequate...

BACKGROUND: Weight recidivism after Roux-en-Y gastric bypass (RYGB) is a common problem. Often, this weight loss failure or regain may be due to a wide gastrojejunostomy (GJ). We evaluated the feasibility and safety of a novel approach of laparoscopic wedge resection of gastrojejunostomy (LWGJ) for a wide stoma after RYGB associated with weight recidivism. METHODS: This is a single-center retrospective study of a prospectively collected database. We analyzed outcomes of patients with weight recidivism after RYGB and a documented wide GJ (>2 cm) on imaging, who underwent LWGJ between 11/2013 and 05/2016...

REVIEW
Pedro Mario Espino-Grosso, Benjamin Kirk Canales
Obesity is rampant across the spectrum of age, gender, and race in the Unites States. Paralleling this epidemic, kidney stone prevalence is also rising, affecting nearly 1 in 11 individuals. Bariatric surgical procedures, such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), are the most effective weight loss options for morbidly obese or severely obese individuals with comorbidities. A number of studies have linked kidney stone development to bariatric surgical history, particularly RYGB, which portends up to a threefold increase in calcium oxalate stone risk compared with age-matched, obese controls...
