Final score in laparoscopic cholecystectomy

Background: The role of intraoperative fluorocholangiography (IOC) in laparoscopic cholecystectomy (LC) is controversial. We evaluated the use of IOC at an institution where the study is performed routinely. Methods: Records of all patients undergoing LC during a 3-year period ending January 1, 1996 were reviewed. Results: A total of 1207 patients received IOC, whereas 116 patients did not. IOC findings were categorized as follows: normal, 1016 cases (84%); CBD stone, 149 cases (12.3%); anomalies, 23 cases (1.9%); duodenal diverticula, 10 cases (0.8%); ductal strictures, four cases (0.3%); and CBD diverticula, 5 cases (0.4%). In the 116 patients who did not receive IOC, 35 of the procedures could not be performed, whereas 81 were not attempted. Of the 149 IOC that showed CBD stones, two were false positives. Anomalies included accessory right hepatic ducts (11 cases), cystic ducts joining the right hepatic duct (seven cases), and abnormal cystic duct entries (five cases). Duct injuries occurred in 5 cases (0.4%), three before and two after IOC. Four injuries were minor; IOC prevented CBD transection. Conclusions: Routine IOC is feasible, safe, accurate, and provides critical information of immediate use during LC. By treating ductal stones at operation and identifying patients without CBD stones, IOC minimizes need for postoperative studies, including endoscopic retrograde cholangiography (ERC).
