title: Gallbladder disease in patients undergoing laparoscopic adjustable gastric banding.
abstract: BACKGROUND
  Patients undergoing weight loss surgery may have an increased incidence of subsequent gallbladder disease. Management options include treatment of symptomatic disease only, preoperative ultrasonography and concurrent cholecystectomy in presence of stones, routine concurrent cholecystectomy, and choleretic therapy postoperatively. Here we report our approach to patients undergoing laparoscopic adjustable gastric banding (LAGB) and subsequent outcomes.
  
  
  METHODS
  A retrospective review of all consecutive patients undergoing LAGB at our institution was performed. Only symptomatic patients were preoperatively evaluated for cholelithiasis and underwent concurrent cholecystectomy. No choleretics were used postoperatively. Weight loss data were collected when patients returned for band adjustments. All band adjustments were patient-driven and performed under fluoroscopic guidance.
  
  
  RESULTS
  Between November 2001 and July 2004, 324 patients underwent LAGB. Mean starting weight was 143.6 kg (range, 92.3 to 250.5 kg), and mean body mass index was 50.5 kg/m(2) (range, 35.6 to 80 kg/m(2)). Fifty-six patients had undergone previous cholecystectomy, and 7 other patients underwent concurrent cholecystectomy. Average follow-up was 12.5 months (range, 1.3 to 31 months). Absolute weight loss for all patients ranged from - 2.7 to 102.3 kg. Of the remaining patients, 3 underwent subsequent uneventful laparoscopic cholecystectomy for symptomatic cholelithiasis. No independent predictors for post-LAGB gallbladder disease were identified.
  
  
  CONCLUSIONS
  Despite significant weight loss, few patients require cholecystectomy after LAGB. Routine preoperative ultrasonography, empiric cholecystectomy, and choleretic therapy are of questionable value in LAGB patients. Considering the magnitude of weight loss in our patients, empiric cholecystectomy for all bariatric procedures may merit further investigation.
