10-Year outcomes of marginal ulcer formation and impact of gastrojejunostomy technique in Roux-en-Y gastric bypass.

Background: Marginal ulcers (MUs) are potential complications following Roux-en-Y gastric bypass (RYGB) surgery. Our institution performs 3 different laparoscopic gastrojejunal anastomosis (GJA) techniques. The aim of this study was to analyze the incidence of MUs between 25-mm circular stapler (CS), linear stapler (LS), and hand-sewn (HS) GJA techniques using data collected over a 10-year period.

Metabolic and Bariatric Surgery Outcomes in African American Patients: a Single Institution Experience.

Background: The incidence of obesity in African Americans (AAs) is higher than in non-AA in the USA. Previous studies using large national databases report that AA patients have worse outcomes than non-AA patients.

Objectives: To assess perioperative outcomes among AA patients after MBS at a center of excellence (COE) that serves a large, diverse patient population.

African American Patients Experience Worse Outcomes than Hispanic Patients Following Bariatric Surgery: an Analysis Using the MBSAQIP Data Registry.

Background: Obesity rates in Hispanics and African Americans (AAs) are higher than in Caucasians in the USA, yet the rate of metabolic and bariatric surgery (MBS) for weight loss remains lower for both Hispanics and AAs.

Methods: Patient demographics and outcomes of adult AA and Hispanic patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) procedures were analyzed using the MBSAQIP dataset [2015-2018] using unmatched and propensity-matched data.

Results: In total, 173,157 patients were included, of whom 98,185 were AA [56.

Safety of biliopancreatic diversion with duodenal switch in patients with body mass index less than 50 kg/m.

Introduction: Biliopancreatic diversion with duodenal switch (BPD-DS) has often been reserved for patients with BMI > 50 kg/m. We aim to assess the safety of BPD-DS in patients with morbid obesity (BMI 35 kg/m and < 50 kg/m) using a 150-cm common channel (CC), 150-cm Roux limb, and 60-fr bougie.

Methods: A retrospective review was performed on patients with a BMI < 50 mg/k who underwent a BPD-DS in 2016-2019 at a single institution.

The role of total alimentary limb length in Roux-en-Y gastric bypass: a systematic review.

Background: Roux-en-Y gastric bypass (RYGB) is an established surgical treatment for obesity. Variations in limb length during RYGB procedures have been investigated for optimizing weight loss while minimizing nutritional deficiencies. The role of the total alimentary limb length (TALL; Roux limb plus common channel [CC]), however, is poorly defined.

Safety of Primary Versus Revisional Biliopancreatic Diversion with Duodenal Switch in Patients with Super Obesity Using the MBSAQIP database.

Introduction: For patients with super obesity (BMI > 50 kg/m), biliopancreatic diversion/duodenal switch (BPD/DS) can be an effective bariatric operation. Technical challenges and patient safety concerns, however, have limited its use as a primary procedure. This study sought to assess the safety of primary versus revisional BPD/DS.

Why Size Matters: an Evaluation of Gastric Pouch Size in Roux-en-Y Gastric Bypass Using CT Volumetric Analysis and its Effect on Marginal Ulceration.

Purpose: Marginal ulceration (MU) is a common long-term complication following Roux-en-Y gastric bypass (RYGB). The causes of MU after RYGB are multifactorial and include surgical technique of constructing the gastrojejunal anastomosis (GJA). The purpose of this study is to evaluate the relationship between gastric pouch size in RYGB and MU using CT volumetrics.

Internal hernia at Petersen's space after laparoscopic Roux-en-Y gastric bypass: 6.2% incidence without closure--a single surgeon series of 1047 cases.

Background: Recent reports describing a gastric bypass technique and the need for closure at Petersen's space using an antecolic antegastric laparoscopic method have differed in the incidence of internal hernia. We report a 6.2% incidence without closure of Petersen's space in a 1047-case, single-surgeon practice.
