Surgical interventions for weight-related diseases (SWRD) may have substantial and sustainable effect on weight reduction, also leading to a higher remission rate of type 2 diabetes (T2D) mellitus than any other medical treatment or lifestyle intervention. The resolution of T2D after Roux-en-Y gastric bypass (RYGB) typically occurs too quickly to be accounted for by weight loss alone, suggesting that these operations have a direct impact on glucose homeostasis. The mechanisms underlying these beneficial effects however remain unclear...

Hany Shehab, Khaled Gawdat
BACKGROUND: Banded-gastric bypass is a highly effective bariatric procedure, yet the possibility of band erosion remains a significant drawback. Surgical removal of eroded bands may be associated with significant morbidity. In this study, we assess the efficacy and safety of a solely peroral endoscopic approach for the management of eroded bands in patients with a banded-gastric bypass. MATERIALS AND METHODS: Starting January 2012, all patients with banded-gastric bypass and an eroded band were subjected to an attempt at peroral endoscopic removal using endoscopic scissors and/or argon plasma coagulation (APC), regardless of the circumference of band eroding inside the lumen...

PURPOSE: Bariatric surgery has been associated with bone remodeling changes. The action of adipokines on the expression of receptor activator of nuclear factor kappa β ligand (RANKL) and osteoprotegerin (OPG) and on an increase in sclerostin could be related to these changes. MATERIALS AND METHODS: This study aimed to assess the repercussions of weight loss, fat mass (FM), and fat-free mass (FFM) loss and biochemical and hormonal changes on bone remodeling markers after Roux-en-Y gastric bypass (RYGB)...

BACKGROUND: Rates of weight normalization and obesity remission after Roux-en-Y gastric bypass (GB) are unknown. This study evaluated weight loss, rates of achieving body mass index (BMI) <25 or 30 kg/m(2), recidivism, and predictors of success following GB. METHODS: We retrospectively studied weight and BMI at baseline, 2 and 6 months, and annually at 1-7 years in 219 patients undergoing GB at the University of Michigan from January 2008 to November 2010...

OBJECTIVE: There are very few studies on laparoscopic adjustable gastric banding (LAGB) in obese adolescents with follow up for more than 36 months, let alone good prospective data beyond 24 months in Australian adolescents. We aimed to evaluate medium term (>36 months) safety and efficacy of LAGB in adolescents with severe obesity. METHODS: This is a prospective cohort study (March 2009-December 2015) in one tertiary referral hospital including obese adolescents (14-18 years) with a body mass index (BMI) >40 (or ≥35 with comorbidities) who consented to have LAGB...

BACKGROUND: Obesity and its consequences have now reached worldwide pandemic proportions. Among treatments, bariatric interventions are the most effective for weight reduction. Here, we describe the change in anthropometric measurements (AMs) of 615 adult bariatric procedure patients seen in the private practice of a registered dietitian (RD) in Bogotá, Colombia. METHODS: Observational retrospective study of AMs recorded between 1996 and 2013 for patients who had laparoscopic sleeve gastrectomy (LSG, n = 290), laparoscopic adjustable gastric banding (LAGB, n = 207), and laparoscopic Roux-EN-Y gastric bypass (LRYGB, n = 36) or the non-surgical gastric balloon (GB, n = 82) procedure...

BACKGROUND: We assessed the risk of coronary heart disease (CHD) after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) for peptic ulcer disease (PUD). METHODS: The Taiwan National Health Insurance Research Database was used, and 6160 patients undergoing SGBIIA for PUD were identified as the surgical cohort. A total of 24,540 patients from the PUD population not undergoing surgery selected by frequency-matching were identified as the non-surgical cohort...

BACKGROUND: Staple line leak after laparoscopic sleeve gastrectomy (LSG) still represents the most feared complication. The purpose of this study was to investigate whether there are factors that increase the risk for a leakage. Furthermore, we aimed to analyze the impact of a leak on weight change and resolution of comorbidities. METHODS: Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered. For the current analysis, all adult subjects that had undergone primary LSG from 2005 to 2014 were considered...

BACKGROUND: The increasing prevalence of obesity in worldwide is one of the most serious chronic public health problems and is considered to be a global epidemic. Bariatric surgical procedures have also been applied more often with increased prevalence of obesity. As a result, the incidence of surgical complications has increased. Preoperative evaluation is quite important for these patients. AIMS: The aim of our study is to determine the predictors of perioperative pulmonary complications of laparoscopic sleeve gastrectomy...

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disease worldwide and is highly associated with obesity. The prevalences of both conditions have markedly increased in the Western civilization. Bariatric surgery is the most effective treatment for morbid obesity and its comorbidities such as NAFLD. OBJECTIVES: Measure postoperative liver fat fraction (LFF) in bariatric patients by using in-opposed-phase MRI, a widely available clinical tool validated for the quantification of liver fat METHODS: Retrospective analyses of participants, who underwent laparoscopic Roux-Y-gastric-bypass (17) or laparoscopic sleeve gastrectomy (2) were performed using magnetic resonance imaging (MRI), bioelectrical impedance analysis (BIA), and anthropometric measurements 1 day before surgery, as well as 6, 12, and 24 weeks after surgery, LFF was calculated from fat-only and water-only MR images...

PURPOSE: Obese patients are known to be in an in vitro hypercoagulable state relative to normal-weight patients. Our study aimed to identify markers of enhanced coagulability (endogenous thrombin potential (ETP)) in morbidly obese patients using the thrombin generation (TG) test. MATERIALS AND METHODS: All patients scheduled for laparoscopic bariatric surgery (LBS) between September 1, 2014 and January 31, 2016 were eligible for our prospective study. We used logistic regression to compute the odds ratio (OR) across ETP quartile distributions to evaluate the risk of enhanced TG...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is a common surgical therapeutic option for obese patients, with debate about the value of routine histopathologic examination of LSG specimens. We assessed the following: prevalence of different histopathologic changes in LSG specimens, risk factors associated with premalignant and with frequent histopathologic changes, and whether routine histopathologic examination is warranted for LSG patients with nonsignificant clinical history. METHODS: Retrospective review of records of all LSG patients operated upon at Hamad General Hospital, Qatar (February 2011-July 2014, n = 1555), was conducted...

INTRODUCTION: Inadequate weight loss (IWL)/weight regain (WR) and gastro-esophageal reflux disease (GERD), unresponsive to medical management, are two most common indications for conversion of sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB). This study reports detailed outcomes of conversion of SG to RYGB for these two indications separately. METHODS: We interrogated our prospectively maintained database to identify patients who underwent a conversion of their SG to RYGB in our unit...

BACKGROUND: The effects of bariatric surgery on excess weight loss (EWL) and comorbidities are proven. Still, a significant number of patients prefer conservative therapy (ConsP). OBJECTIVES: The goal of this study was to examine why ConsP and patients awaiting bariatric surgery (SurgP) choose which therapy, and to define the differences in their expectations. SETTING: Prospective study, 1 university hospital, 1 general hospital, Germany. METHODS: ConsP and SurgP were asked to complete a questionnaire...

BACKGROUND: Gastric plication is a minimally invasive bariatric surgical procedure, where the greater curvature is plicated inside the gastric lumen. Our aims were to analyze the effectiveness of gastric plication on the resolution of obesity, impaired glucose tolerance, and fatty liver in an experimental model of diet-induced obesity (DIO) and to evaluate changes in glycerol metabolism, a key substrate for adiposity and gluconeogenesis, in adipose tissue and the liver. METHODS: Male Wistar DIO rats (n = 58) were subjected to surgical (sham operation and gastric plication) or dietary interventions [fed a normal diet (ND) or high-fat diet (HFD) or pair-fed to the amount of food eaten by gastric-plicated animals]...
