Successful outcome of sphincterotomy and 7 French pigtail stent insertion in the management of post-cholecystectomy bile leaks.

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is widely used to manage post-cholecystectomy bile leaks. However, the best endoscopic intervention remains controversial. We investigated the success of a 7 French double pigtail stent following sphincterotomy in the management of such bile leaks.

METHODS

Between July 1998 and June 2008, 48 patients were referred for ERCP for presumed post-cholecystectomy bile leaks. Leaks were confirmed at ERCP and managed by a combination of sphincterotomy and stent insertion unless contraindicated.

RESULTS

Bile duct cannulation was successful in 44 (91.7%) patients. A leak of the cystic duct was demonstrated in 19 (43.2%) patients, the duct of Luschka in 11 (25.0%), and the common hepatic duct in 5 (11.4%). Complete transection of the common bile duct occurred in 4 patients. The remaining patients had no cholangiographic evidence of a leak. Sphincterotomy was performed in 34 patients. A 7 French double pigtail plastic stent was placed in all 35 patients with cholangiographic evidence of a bile leak. No bile leaks were demonstrated at a follow-up of 8-16 weeks and all stents were removed successfully.

CONCLUSION

The combination of sphincterotomy and insertion of a 7 French double pigtail stent results in excellent outcomes in the management of post-cholecystectomy bile leaks.
