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. Chi-square, Fisher's exact, or Wilcoxon rank-sum tests were used to compare outcomes. Concomitant CCY was performed on a selective basis. RESULTS: Three thousand and four patients underwent a RYGB (LRYGB n = 2458, open RYGB n = 546). Fifty-two percent (n = 1670) of patients had undergone CCY at any stage. Thirty-one percent of patients (n = 933) had CCY prior to RYGB, 13% (n = 403) had a concomitant CCY and 13% (n = 214) of the remainder required interval CCY. In the LRYGB subgroup, 29.9% (n = 735) had a prior CCY; 12.9% (n = 202) of those with an in situ gallbladder required interval CCY. Those who underwent concomitant CCY/LRYGB (n = 328) were compared with LRYGB alone (n = 1231). The concomitant CCY group was significantly older and had higher percentage of females, higher preoperative BMI, higher Charlson Comorbidity Index, and a higher medication count. There was no significant difference in BMI nadir, length of stay, complications, or mortality. Interval CCY had a higher incidence of CCY-related complications. CONCLUSION: Our study suggests a higher percentage of bariatric patients with in situ gallbladders will undergo interval CCY than documented in recently published guidelines. Concomitant CCY can be performed without an increase in length of stay or complications. Interval CCY may be associated with a higher complication rate.
