Cholecystectomy in morbidly obese patients

Indications for performing cholecystectomy simultaneously with a gastric bariatric operation remain controversial. The extremes are to always perform cholecystectomy or to perform cholecystectomy only when there are palpable stones or the gallbladder is grossly diseased. Since 1975, 136 cholecystectomies have been performed simultaneously in 724 patients who had a gastric bariatric operation. Cholecystectomy had been performed before the bariatric operation in 120 and was required later in 18 patients. The clinical records, anesthesia, pathology, and operative reports provide the data for this study. Simultaneous cholecystectomy was done through the vertical midline incision used for gastric bariatric operation. No patients had the gallbladder bed closed or were drained. Operative cholangiogram were not performed because this procedure would have been difficult and significantly prolonged because of the obesity. No patients have developed postoperative choledocholithiasis. One patient developed a complication related to cholecystectomy, a common bile duct stricture. The length of the operation and the postoperative hospitalization with and without simultaneous cholecystectomy were compared. The results of intraoperative ultrasound studies performed upon these patients are described and discussed. It is concluded that cholecystectomy should be performed simultaneously with all gastric bariatric operations when there is gross or echogenic evidence of gallbladder disease. Cholecystectomy does not significantly prolong or complicate the gastric bariatric operation.
