BACKGROUND: Morbid obesity is one of the major risk factors for @entity1085 , and this risk is even greater following rapid @entity353 . Because of this, prophylactic cholecystectomy has been offered to our @entity1 undergoing the @entity356 ( @entity356 ). A study was undertaken to determine the incidence of @entity1085 in @entity1 undergoing this prophylactic cholecystectomy. METHOD: The records of all @entity1 who underwent @entity356 from June 1999 through December 2000 were reviewed. Pathologic findings of the gallbladder were documented as cholelithiasis, @entity2679 , cholesterolosis, @entity1127 or normal. RESULTS: 761 @entity1 underwent the operation. 178 @entity1 (23%) had cholecystectomy before the surgery. 154 (20%) had @entity5990 documented by ultrasound and had cholecystectomy at the time of the surgery. 324 of the 429 @entity1 with negative preoperative findings by ultrasound had pathologic evidence of @entity1085 . CONCLUSION: Because of the high incidence of @entity1085 even with negative preoperative findings in morbidly @entity28 @entity1 and the lack of significant morbidity with cholecystectomy in experienced hands, routine cholecystectomy at the time of the @entity353 operation is justified.
