Treatment of common bile duct injuries during laparoscopic cholecystectomy: endoscopic and surgical management

Abstract

The increase of laparoscopic cholecystectomy has resulted in an increase of bile duct injuries. The purpose of this article is to define the types of injury, their occurrence and frequency, and their management by endoscopic and surgical techniques. Three investigations were included in the present study. 1. A 3-year retrospective study among 29 hospitals with 25,007 laparoscopic cholecystectomies. 2. An 8-year prospective study at our institution of 6488 patients. 3. A prospective endoscopic study of 94 patients with injuries and strictures of the common bile duct (CBD) after laparoscopic cholecystectomy. A special classification for bile duct injuries was developed. Among 25,007 patients from 29 hospitals, a total of 74 lesions were detected with an incidence of 0.29%. At our institution, 20 cases were seen (0.29%) with type I, II, and III injuries. The 94 cases managed by endoscopic procedure were submitted to endoscopic retrograde cholangiopancreatography (ERCP) and papillotomy, with placement of several stents 5 to 10 F during 8 months. The results of this procedure have been excellent to good in 76% of the cases up to 3 years of follow-up. According to our previous and present experience, bile duct injuries after laparoscopic procedure are two times higher than after open procedure. The best treatment is the prevention of these injuries by careful surgical technique. If they occur, the best moment to repair them is during surgery. If they are noticed after the operation, endoscopic or surgical procedures can be employed.
