[Iatrogenic biliary injuries during cholecystectomy].

AIM OF THE STUDY: To analyze our experience with biliary injuries during cholecystectomy in order to determine associated risk factors, morbidity, and results after reconstruction.

PATIENTS AND

METHODS

Review of the series of patients referred to our department for biliary injury during cholecystectomy over a 9-year period. Items regarding the type of lesion, risk factors, management, morbidity, and late results were recorded.

RESULTS

Fifteen patients were referred to our department for bile duct injury during cholecystectomy between 1997 and 2005 (14 by laparoscopy and four by laparotomy; nine women and nine men). The main surgical indication was biliary colic (n=8). Three patients were operated on in an emergency setting (for acute cholecystitis). In nine patients the gallbladder wall was inflammatory. Intraoperative cholangiography was performed in nine patients, but revealed just one injury. Lateral injury to the bile duct was the most frequent type of lesion. In nine patients, the injury was detected intraoperatively and a biliary drainage was left in place; five of them had a synchronic repair and three required later reconstruction. Nine patients had a delayed identification of biliary injury; six of them required a biliodigestive anastomosis. Two patients died, three had several episodes of acute cholangitis after reconstruction and two presented incisional hernia.

CONCLUSION

An inflammatory environment is the main risk factor for biliary injury during cholecystectomy. Bile duct injury is more frequent with laparoscopic cholecystectomy but can also occur with an open approach. Intraoperative cholangiography does not prevent biliary injuries nor detect them accurately. Biliary drainage can reduce morbidity for intraoperatively detected injuries and may be a sensitive approach for the surgeon with no hepatobiliary experience. Morbidity is increased in patients with delayed identification of the injury.
