During a 7 year period, 200 consecutive morbidly @entity28 @entity1 underwent a standardized gastric exclusion procedure. Group A was composed of the first 120 @entity1 and Group B of the last 80 @entity1 . In Group A, 22 @entity1 had undergone a previous cholecystectomy and 12 @entity1 had a cholecystectomy at the time of gastric exclusion because of positive diagnostic studies or palpation of stones. Of the remaining 87 @entity1 in this initial group who were at risk for the development of @entity1085 , 24 (27.6 percent) required a cholecystectomy in the first 3 postoperative years (mean 15.6 months). Twelve @entity1 had acute @entity2679 , 3 @entity1 had @entity2877 , and 1 @entity1 had @entity656 . In Group B, 18 @entity1 had a previous cholecystectomy, 15 had positive diagnostic studies (ultrasonography and oral cholecystography) preoperatively, and 47 had negative studies. Cholecystectomy was routinely performed at the time of gastric exclusion surgery in the 62 @entity1 with gallbladders in Group B. Of the 47 @entity1 who had normal preoperative diagnostic studies, 40 (85.1 percent) had abnormal histologic findings in the gallbladder. Only seven @entity1 in Group B had a normal gallbladder (14.7 percent). We conclude that @entity1085 is considerably more frequent in the morbidly @entity28 population (91.3 percent) than has previously been recognized, that diagnostic studies are frequently inaccurate, and that postoperative @entity1085 is common (28.7 percent). On the basis of these results, routine cholecystectomy at the time of gastric exclusion surgery is recommended.
