After the DS, the gallbladder is pointless - your bile does NOT mix with your food in a bolus as it is released from the pyloric valve, and will end up trickling down the biliopancreatic limb anyway. It has no physiological purpose for a DSer.
I'm not fond of keeping useless organs, especially ones that can get cancer, infections, stones, and (in our case) can be a source of horrendous pain when they go bad, and which have to be ruled out in a differential diagnosis as a source of belly pain thereafter. I argued with Rabkin about whether it made sense to take out a perfectly healthy gallbladder, and he convinced me the answer is yes.
It's ursodiol, by the way - and it doesn't work very well (and causes diarrhea).

My opinion: appendix and gallbladder OUT with the DS, while they're in there anyway. Then you never have to worry about gall stones or appendicitis ever again. One surgery, one recovery.

Abstract
PURPOSE:
Rapid weight loss is a risk factor for gallstone formation, and postoperative treatment options for gallstone formation are still part of scientific discussion. No prospective studies monitored the incidence for gallstone formation and subsequent cholecystectomy after bariatric surgerylonger than 5 years. The aim of the study was to determine the incidence of gallstone formation and cholecystectomy in bariatric patients over 10 years.
MATERIALS AND METHODS:
One hundred nine patients were observed over 10 years after laparoscopic gastric banding or gastric bypass/gastric sleeve. The incidence of gallstone formation and cholecystectomy was correlated to longitudinal changes in anthropometric parameters.
RESULTS:
In total, 91 female and 18 male patients were examined. Nineteen patients had postoperative gallstone formation, and 12 female patients required cholecystectomy. The number needed to harm for gallstone formation was 7.1 and 2.3 cases in the banding group and gastric bypass/gastric sleeve group, respectively. The number needed to harm for cholecystectomy was 11.6 and 2.5 cases in the banding group and the gastric bypass/gastric sleeve group, respectively. Weight loss was higher in patients requiring subsequent cholecystectomy. Mean follow-up tocholecystectomy was 21.5 months with the latest operation after 51 months.
CONCLUSION:
Female gender and rapid weight loss were major risk factors for postoperative cholelithiasis. Ultrasound examinations within 2 to 5 years are recommended in every patient, independent of bariatric procedure. Pharmacologic treatment should be considered in high risk patients within 2 to 5 years to prevent postoperative cholelithiasis. This helps to optimize patient care and lowers postoperative morbidity.

Abstract
BACKGROUND:
The natural history of gallstone formation after laparoscopic sleeve gastrectomy (LSG), the incidence of symptomatic gallstones, and timing of cholecystectomy are not well established.
METHODS:
A retrospective review of prospectively collected database of 150 patients that underwent LSG was reviewed.
RESULTS:
Preoperatively, gallbladder disease was identified in 32 of the patients (23.2%). Postoperatively, eight of 138 patients (5.8%) became symptomatic. Namely, three of 23 patients (13%) who had evident cholelithiasis preoperatively developed complicated cholelithiasis. From the cohort of patients without preoperative cholelithiasis, five of 106 patients (4.7%) experienced complicated gallstones after LSG. Total cumulative incidence of complicated gallstones was 4.7% (95% CI: 1.3-8.1%). The gallbladder disease-free survival rate was 92.2% at 2 years. No patient underwentcholecystectomy earlier than 9 months or later than 23 months indicating the post-LSG effect.
CONCLUSION:
A significant proportion of bariatric patients compared to the general population became symptomatic and soon developed complications after LSG, thus early cholecystectomy is warranted.
Routine concomitant cholecystectomy could be considered because the proportion of patients who developed complications especially those with potentially significant morbidities is high and the time to develop complications is short and because of the real technical difficulties during subsequent cholecystectomy.

Abstract
BACKGROUND:
Rapid weight loss after bariatric surgery is associated with gallstone formation, and cholecystectomy is required in up to 15% of patients. Prophylactic cholecystectomy or prophylactic ursodiol administration in the postoperative period have been suggested to address this problem. The objectives of this study were to investigate the frequency and timing of cholecystectomies after bariatric surgery and to determine the associated risk factors in patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic adjustable gastric band (LAGB), or laparoscopic sleeve gastrectomy (LSG).
METHODS:
Data prospectively collected in an institutional database were analyzed. Differences among the 3 procedures and the effects of ursodiol administration, patient demographic characteristics, postoperative weight loss, and individual surgeon practices on cholecystectomy rates were examined. Survival analysis and proportional hazard models were used.
RESULTS:
Of 1398 patients, 109 (7.8%) underwent cholecystectomy with a median follow-up of 49 (range 12-103) months. Cholecystectomyfrequency was 10.6% after LRYGB, significantly higher than 2.9% after LAGB (P < .001), and 3.5% after LSG (P = .004). The frequency was highest within the first 6 months (3.7%), but declined over time to < 1% per year after 3 years.
Ursodiol administration did not affect cholecystectomy rates (P = .97), and significant intersurgeon variability was noted. Excess weight loss (EWL)>25% within the first 3 months was the strongest predictor of postoperative cholecystectomy (P<.001). Cox hazards model revealed 1.25 odds ratio per 10% EWL within 3 months, and odds ratio .77 per decade of life. In addition, white patients had 1.45 times higher cholecystectomy rates than did black patients. Preoperative body mass index, gender, and surgeon did not affect cholecystectomy rates.
CONCLUSION:
Bariatric surgery is associated with a low frequency of postoperative cholecystectomy, which is highest early after surgery and mainly determined by the amount of EWL within the first 3 months. The results of the present study do not support routine prophylactic cholecystectomy at the time of bariatric surgery
in asymptomatic patients.
