Surgical treatment of iatrogenic lesions of the proximal common bile duct.

Abstract

Between January 1979 and September 1999 a series of 96 patients were operated on at our institution for iatrogenic biliary injuries, and among them 62 involved the proximal biliary tract. Injuries, according to the Strasberg classification, were type E2 in 18 patients, type E3 in 29 patients, and type E4 in 15 patients. The most frequent primary surgical procedures were laparoscopic cholecystectomy in 27 of the 62 patients (43.6%) and open cholecystectomy in 30 patients (48.3%). Previous repair had been attempted in 25 patients (40.3%). A total of 58 cholangiojejunostomies were performed. Repair had been performed directly, and a T-tube had been left in the main bile duct in four patients with E2 Strasberg lesions. Postoperative death occurred in four patients (6.4%). Outcome was graded as excellent, good, or poor depending on clinical symptoms, liver function tests, and the need for reintervention due to anastomotic stricture. The final outcome was evaluated in 54 patients. The mean follow-up was 5.9 +/- 0.3 years, with the longest follow-up 10.2 years. Following our first repair 49 of the 54 patients (90.7%) had excellent results, 1 (1.9%) had good results, and 4 (7.4%) had poor results. None of the patients who underwent immediate or early repair had complications. Diagnostic and therapeutic courses are given on the basis of the type of lesion and the timing of repair. We emphasize the importance of timing (i.e., carrying out surgical repair as soon as possible) and of cholangiojejunostomy reconstruction in respect to defined technical principles. Moreover, we believe that repair treatment at a hepatobiliary center with multidisciplinary competence greatly influences the final long-term outcome.
