roux-en-y gastric bypass

INTRODUCTION: The International Federation for Surgery for Obesity and Metabolic Disorders (IFSO) Global Registry aims to provide descriptive data about the caseload and penetrance of surgery for metabolic disease and obesity in member countries. The data presented in this report represent the key findings of the eighth report of the IFSO Global Registry. METHODS: All existing Metabolic and Bariatric Surgery (MBS) registries known to IFSO were invited to contribute to the eighth report...

Introduction: A substantial percentage of patients undergoing bariatric surgery are of childbearing age. Pregnancy outcomes after bariatric surgery are known. However, there are limited data on the impact of pregnancy on weight loss after surgery. Objectives: This study aims to evaluate the effects of pregnancy on post-bariatric surgery weight loss trajectories (WLTs) and to determine the association with age and initial weight. Methods: All who had primary bariatric surgeries (Roux-en-Y gastric bypass or sleeve) between September 2015 and July 2020 were classified into two groups: post-surgery gravid (GG) and post-surgery non-gravid (NG)...

Roux-en-Y gastric bypass (RYGB) patients are at risk of creating potential spaces for possible internal hernias during the procedure. During pregnancy, the pregnant uterus elevates the bowel, increasing intra-abdominal pressure. Cases reported to date have described mild abdominal pain and no evidence of peritoneal irritation, with inconclusive ultrasound and MRI findings for diagnosis of Petersen's hernia. We present the case of a 42-year-old female patient with a history of RYGB eight years earlier without complications, with a pregnancy of 34 weeks of gestation...

Although bariatric surgery is an effective treatment for type 2 diabetes by inducing weight loss and augmenting gut hormone secretion, the immediate effect on beta-cell function itself remains to be elucidated in type 2 diabetes. Therefore, a prospective, randomized trial was performed in 30 patients with insulin-treated type 2 diabetes and a body mass index ≥ 35 kg/m2 . Patients were randomly assigned (1:1:1) to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) in combination with protein-sparing modified fast (PSMF), or to PSMF alone...

The use of endoscopic retrograde cholangiography (ERCP) for diagnostic and therapeutic interventions on the pancreaticobiliary system has steadily increased, but the standard approach through the oropharynx is prohibited after Roux-en-Y (RYGB) gastric bypass surgery. Laparoscopic access to the gastric remnant allows for the completion of ERCP using the standard side-viewing duodenoscope to facilitate the completion of standard and advanced endoscopic maneuvers. Here, we describe our experience with the technical aspects of safe and effective performance of laparoscopic-assisted ERCP...

Diets varying in macronutrient composition, energy density, and/or palatability may cause differences in outcome of bariatric surgery. In the present study, rats feeding a healthy low fat (LF) diet or an obesogenic high fat/sucrose diet (HF/S) were either subjected to Roux-en-Y gastric bypass surgery (RYGB) or sham surgery, and weight loss trajectories and various energy balance parameters were assessed. Before RYGB, rats eating a HF/S (n=14) diet increased body weight relative to rats eating a LF diet (n=20; p<0...

There is sparse literature on the development of malignancy in remnant gastric stomach after bariatric Roux-en-Y gastric bypass surgery. We report a case of overt upper gastrointestinal bleeding from malignant adenocarcinoma in the remnant stomach presenting several years after bariatric Roux-En-Y gastric bypass surgery. The mass in the remnant stomach was surgically resected, and the patient was subsequently diagnosed with Lynch syndrome on genetic analysis.

OBJECTIVE: To assess diet quality and its association with body and biochemical parameters in patients who underwent Roux-en-Y gastric bypass (RYGB). METHODS: Prospective observational study with individuals of both sexes subjected to RYGB. Body composition, biochemical parameters, and diet quality were assessed before and six months after RYGB. Diet quality was assessed by the Healthy Eating Index (HEI). Data were analyzed by the paired t-test or Wilcoxon signed-rank test, with a significance level of 5%...

INTRODUCTION: Enhanced Recovery Programs (ERPs) mitigate racial disparities in postoperative length of stay (LOS) for colorectal populations. It is unclear, however, if these effects exist in the bariatric surgery population. Therefore, this study aimed to evaluate the racial disparities in LOS before and after implementation of bariatric surgery ERP. METHODS: A retrospective cohort study was performed using data from a single institution. Patients undergoing minimally invasive sleeve gastrectomy or Roux-en-Y gastric bypass from 2017 to 2019 (pre-ERP) or 2020-2022 (ERP) were included...

INTRODUCTION: The purpose of this study is to investigate the impact of preoperative comorbidities, including depression, anxiety, type 2 diabetes mellitus, obstructive sleep apnea, hypothyroidism, and the type of surgery on %EBWL (percent estimated body weight loss) in patients 1 year after bariatric surgery. Patients who choose to undergo bariatric surgery often have other comorbidities that can affect both the outcomes of their procedures and the postoperative period. We predict that patients who have depression, anxiety, diabetes mellitus, obstructive sleep apnea, or hypothyroidism will have a smaller change in %EBWL when compared to patients without any of these comorbidities...

INTRODUCTION: There has been a significant increase in the prevalence of morbid obesity across the globe. Various non-surgical weight loss options have shown limited long-term efficacy, leading to the popularity of surgical treatment alternatives with long-term efficacy. PRESENTATION OF CASE: This case report describes the development of a gastric mucocele in a 51-year-old female patient. The patient initially underwent open butterfly gastroplasty in August 2016...

Bariatric surgery is a routinely performed procedure and is associated with a reduction in all-cause mortality in patients with obesity. However, bariatric surgery has also been linked to increased alcohol use with up to 30% of these patients developing alcohol use disorder (AUD). The mechanism of AUD after bariatric surgery is multifactorial and includes anatomic, metabolic, and neurohumoral changes associated with post-surgical anatomy. These patients are at increased risk of alcohol associated liver disease and, in some cases, require liver transplantation...

BACKGROUND: It is unclear whether routine upper gastrointestinal swallow study (SS) in the immediate postoperative period is associated with earlier diagnosis of gastrointestinal leak after bariatric surgery. OBJECTIVE: To investigate the relationship between routine SS and time to diagnosis of postoperative gastrointestinal leak. SETTING: MBSAQIP-accredited hospitals in the United States and Canada. METHODS: We conducted an observational cohort study of adults who underwent laparoscopic primary Roux-en-Y gastric bypass (RYGB) (n = 82,510) and sleeve gastrectomy (SG) (n = 283,520) using the MBSAQIP 2015-2019 database...

INTRODUCTION: Bariatric surgery (BS) is the treatment of choice for refractory obesity. Although weight loss (WL) reduces the prevalence of obesity-related comorbidities, not all patients maintain it. It has been suggested that central mechanisms involving dopamine receptors may play a role in successful WL. This protocol describes an observational cross-sectional study to test if the binding of central dopamine receptors is similar in individuals who responded successfully to BS and age- and gender-matched normal-weight healthy individuals (controls)...

Introduction: Sleeve gastrectomy (SG) has become the most frequently performed bariatric operation in the United States. One of the main disadvantages of this procedure is the risk of developing gastroesophageal reflux disease (GERD) after the operation. We aimed to analyze different approaches for the treatment of GERD after SG. Methods: A literature review was performed to identify all possible treatment options for post-SG GERD. All the studies were assessed for full eligibility by manual assessment of their aims, methodology, results, and conclusions...

BACKGROUND: Emergency department (ED) utilization following surgery is poorly understood and places immense strain on the healthcare system, being responsible for up to $38 billion in wasteful spending annually. The aim of this study was to quantify ED utilization following bariatric procedures to identify causes and areas of improvement. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was conducted for all patients who underwent metabolic bariatric surgery (MBS) between November 2006 and June 2019...

INTRODUCTION: Our study aimed to compare the short- and particularly long-term type 2 diabetes mellitus (T2DM) remission prediction abilities of ABCD, individualised metabolic surgery (IMS), DiaRem2, Ad-DiaRem and DiaBetter scoring systems in Turkish adult type 2 diabetic morbidly obese patients who underwent bariatric surgery. PATIENTS AND METHODS: Our study was planned as a retrospective cohort study. A total of 137 patients with T2DM, including 78 sleeve gastrectomy (SG) and 59 Roux-en-Y gastric bypass (RYGB) patients, were included in the 1st-year evaluation after bariatric surgery, and a total of 115 patients with T2DM, including 64 SG and 51 RYGB patients, were included in the evaluation at the end of the 5th year...

BACKGROUND: Patients who undergo metabolic and bariatric surgery (MBS) are at risk for thromboembolism. Patients are susceptible to coronavirus throughout the perioperative period, which also has a well-known association with thrombotic complications. OBJECTIVES: To identify and define the association between venous thromboembolism (VTE) and postoperative coronavirus diagnosis in bariatric surgery patients. SETTING: United States. METHODS: We conducted a retrospective cohort study using the MBS Accreditation and Quality Improvement Program (MBSAQIP) 2021 database to analyze the incidence of VTE within 30 days of surgery...

Obesity management guidelines recommend metabolic bariatric surgery for individuals with body mass index (BMI) ≥35 kg/m2 , regardless of the presence of any obesity-related comorbidity; and for individuals with BMI 30-34.9 kg/m2 with metabolic diseases. Older age is not in itself a contraindication for bariatric surgeries, which can be performed after careful selection and assessment, to decrease the risks of postoperative complications. An essential amount of data has accumulated about bariatric surgery results for persons aged ≥60 years; but data are limited though increasingly accumulating for the ≥65-year-old population...
