Bile duct injuries at laparoscopic cholecystectomy: a single-institution prospective study. Acute cholecystitis indicates an increased risk

Abstract

During the last decade laparoscopic cholecystectomy (LC) has become established as the gold standard. The drawbacks in the form of bile duct (BD) injuries have also come into focus. We present the results of a prospective, consecutive series of 1568 patients with reference to BD injuries regarding risks, management, and preventive measures. The significant complications of all patients operated upon with LC between October 1999 and December 2003 were recorded prospectively. BD injuries were classified according to Strasberg into types A-E. Transected major BDs, injuries of type E, were regarded as "major" injuries and types A, B, C, and D were "minor" injuries. Major BDs were transected in five patients (0.3%), three of whom had acute cholecystitis. In the two patients operated on electively, the BD injuries were detected postoperatively, while they were detected intraoperatively when the operation was performed of necessity. The BDs were all reconstructed with a Roux-en-Y hepaticojejunostomy. Two patients had anastomotic strictures. Minor BD injuries were encountered in 19 patients (1.2%). The 13 patients with leakage from the cystic duct or gallbladder bed, injury type A, were treated by endoscopic (ERC) stenting without sequelae. Five patients sustained a lateral BD injury, type D; they were treated with a simple suture over a T-tube (at LC) or endoscopically (ERC) without further problems. A transected aberrant right hepatic BD, type C injury, was due to its small-caliber sutured. Minor BD injuries could be managed at the primary hospital if the endoscopic expertise were at hand. Acute cholecystitis seems to be a risk factor for BD injuries.
