Bariatric operative procedures: Thirty-day morbidity and mortality

Wenliang Chen, MD, PhD


Early morbidity and mortality rates that occur ≤30 days after the operation are generally low and vary with surgical approach, such as fewer complications and less mortality with the laparoscopic than the open approach [1,2]. Most patients have been discharged from the hospital during this one-month interval after the operation [2]. In addition, the occurrence of an adverse intraoperative event (AIE) also increases the risk of a serious postoperative complication [3].

This topic will review the early (≤30-day) serious postoperative complications that can occur after hospital discharge of the more common bariatric surgical procedures, including laparoscopic Roux-en-Y gastric bypass (LRYGB) and open Roux-en-Y gastric bypass (ORYGB), laparoscopic adjustable gastric band (LAGB), laparoscopic sleeve gastrectomy (LSG), and biliopancreatic diversion with duodenal switch (BPD-DS).

A description of bariatric procedures, indications and preoperative management, and intraoperative and in-hospital complications are reviewed as separate topics.
