title: When is routine operative cholangiography necessary? An evaluation of 200 consecutive patients operated on for gallbladder stones.
abstract: Operative cholangiography (OC) was performed during open standard cholecystectomy in 195 of 200 consecutive patients. The cholangiography was considered suspicious for choledochal stones in 28 patients (14%). Both choledochotomy and choledochoscopy were carried out. Stones in the biliary tree were found in 17 patients and in 11 cases choledochotomy was negative. Cholecystectomy was performed on an emergency basis in 46 patients, 15 of them underwent choledochotomy and in 11 (24%) bile duct stones were found. In 154 electively operated patients six (4%) had choledochal stones. Based on preoperative history choledochal stones were suspected in 30 electively operated patients but only eight had stones in the biliary tree at the time of operation. The percentage of false positive cholangiograms was 6% in the whole material, and unsuspected choledochal stones were diagnosed in 5% respectively. It is recommended that operative cholangiography should be performed routinely in patients subjected to emergency cholecystectomy. In elective operations selective use is acceptable.
