Background
Approximately 20 % of adults over 40 years of age in the USA develop cholelithiasis (Topart et al. Surg Obes Relat Dis. 9(4):526–30, 2013). Despite a higher incidence of biliary complications reported in postbariatric patients, it remains controversial whether simultaneous routine cholecystectomy should be performed during biliopancreatic diversion and duodenal switch (BPD/DS) or if a selective approach is more appropriate. The aim of this study was to evaluate incidence of biliary complications in patients who underwent BPD/DS without simultaneous cholecystectomy.
Methods
Retrospective review of all patients who underwent BPD/DS between 2006 and 2012 was performed.
Results
A total of 361 consecutive patients were included in the study with mean age of 44.8 years (range 20–72), mean body weight of 317.2 lbs (range 205–547), and average body mass index (BMI) of 50.5 kg/m2 (range 34–71.4). Ninety-seven patients were males (26.8 %). Out of 239 patients who still had their gallbladder after the BPD/DS, 52 patients (22.7 %) developed subsequent biliary symptoms (13 patients (5.4 %) in the first year, 25 (11 %) in the second year, and 14 (6.1 %) beyond the second year). During the study period, 40 patients eventually underwent elective laparoscopic cholecystectomy, and 11 had urgent cholecystectomy (9 laparoscopic and 2 open). One patient underwent open common bile duct exploration for ascending cholangitis. Average follow-up was 31 months (12–72 months) with follow-up rate of 95.6 % at 12 months and 92.8 % at 18 months.
Conclusions
Leaving normal gallbladder in situ after BPD/DS is associated with an acceptable risk of biliary events. Risk of developing common bile duct stones is low; however, it may create treatment challenges.
