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 gas...

Description
Summary: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. Methods We used data from adults undergoing laparoscopic gastric bypass for obesity from the Nationwide Inpatient Sample. The Cochran–Armitage trend test was used to assess changes over time. Unadjusted and risk-adjusted generalized linear models were performed to assess predictors of concomitant cholecystectomy and to assess postoperative short-term outcomes. Results A total of 70,287 patients were included: mean age was 43.1 years and 81.6% were female. Concomitant cholecystectomy was performed in 6,402 (9.1%) patients. The proportion of patients undergoing concomitant cholecystectomy decreased significantly from 26.3% in 2001 to 3.7% in 2008 ( p for trend
