title: Peroperative cholangiogram--routine or selective results of a prospective study.
abstract: Peroperative cholangiography (POC) performed as a routine during cholecystectomy for cholelithiasis was evaluated in 102 patients. POC was normal 93 patients. Nine patients had abnormal POCs: 5 were true positive--CBD stones (4) and sphincteric fibrosis (1): 4 were false positive--air bubbles (2) and sphincteric spasm (2). Preoperative indication of CBD stones were present in 12 patients-5 of these had abnormal POC (4 true positive and 1 false positive). CBD exploration was avoided in 7 patients with normal POC. Ninety patients did not have any preoperative indication of CBD stones-4 of these had abnormal POC (1 true positive and 3 false positive). None of the patients with a normal POC had any clinical evidence of residual stones on follow up for one year. POC did not help in any case to delineate biliary ductal anatomy. Routine POC during cholecystectomy should be abandoned and should be performed selectively in patients suspected to have CBD stones only to avoid a negative CBD exploration.
