Is routine cholecystectomy indicated for asymptomatic cholelithiasis in patients undergoing gastric bypass?
GROUND: The purpose of this study was to evaluate the natural history of patients undergoing Roux-en-Y gastric bypass (RYGBP) with known asymptomatic cholelithiasis in whom prophylactic cholecystectomy was not performed at the time of surgery. METHODS: The records of 144 consecutive patients from a single year experience in RYGBP surgery at the University of California, Davis Medical Center were reviewed. Patients undergoing RYGBP were routinely screened for cholelithiasis by ultrasound. Patients who did not have cholecystectomy were managed with ursodiol for 6 months postoperatively. RESULTS: 13 males (9.0%) and 131 females (91%) underwent RYGBP. The mean age was 43 years (SD 8.55), and mean BMI was 46 kg/m2 (SD 6.5). The comorbidities of our patient population included diabetes (14%), hypertension (48%), gastroesophageal reflux disease (50%), dyslipidemia (35%), obstructive sleep apnea (31%), and musculoskeletal complaints (69%). 22 patients were diagnosed with cholelithiasis by ultr
