Update on the mesentery: structure, function, and role in disease.

Over the past 5 years, systematic investigation of the mesenteric organ has expanded and shown that the mesentery is the organ in and on which all abdominal digestive organs develop and remain connected to. In turn, this observation has clarified the anatomical foundation of the abdomen and the fundamental order at that level. Findings related to the shape and development of the mesentery have illuminated its function, advancing our understanding of the pathobiology, diagnosis, and treatment of several abdominal and systemic diseases.

Asymptomatic Cholelithiasis and Bariatric Surgery: a Comprehensive Long-Term Analysis of the Risks of Biliary Disease in Patients Undergoing Primary Roux-en-Y Gastric Bypass.

Purpose: Currently, there is little consensus on management of the in situ gallbladder of patients undergoing gastric bypass. Our aim was to evaluate outcomes of selective concomitant cholecystectomy (CCY) and long-term biliary outcomes after Roux-en-Y gastric bypass (RYGB).

Materials And Methods: We performed a retrospective analysis of patients undergoing laparoscopic RYGB (LRYGB) between 2008 and 2018.

Comparison of short-term outcomes following Roux-en-Y gastric bypass in male and female patients using the MBSAQIP database.

Background: Male sex has long been identified as a risk factor for adverse outcomes, including mortality, after Roux-en-Y gastric bypass (RYGB).

Objectives: The objective of this study was to compare short-term outcomes of patients undergoing laparoscopic RYGB based on biologic sex.

Setting: Geisinger Medical Center, Danville, PA.
