Cholecystectomy Concomitant with Laparoscopic Gastric Bypass: A Trend Analysis of the Nationwide Inpatient Sample from 2001 to 2008

Background Gallstone formation is common in obese patients, particularly during rapid weight loss. Whether a concomitant cholecystectomy should be performed during laparoscopic gastric bypass surgery is still contentious. We aimed to analyze trends in concomitant cholecystectomy and laparoscopic gastric bypass surgery (2001–2008), to identify factors associated with concomitant cholecystectomy, and to compare short-term outcomes after laparoscopic gastric bypass with and without concomitant cholecystectomy.
