Results of choledochjejunostomy in the treatment ofbiliary complications after liver transplantation in the era of nonsurgical therapies

Abstract

Advances in radiological and endoscopic techniques have allowed many biliary complications after orthotopic liver transplantation (OLT) to be managed without surgery. The influence of nonsurgical management on the outcome of patients requiring surgical revision has not been addressed. We reviewed our 10-year experience (October 1988 to January 1998) of Roux-en-Y choledochojejunostomy (CDJ) to treat biliary complications after OLT. Forty-six patients underwent CDJ for biliary complications (32 men, 14 women; age, 22 to 65 years; median, 60 years). Biliary reconstruction at the time of OLT was duct to duct in 41 patients, primary CDJ in 3 patients, and gall bladder conduit in 2 patients. T-tubes were used only in patients with gallbladder conduit. The indication for CDJ was biliary leak (23 patients), stricture (20 patients), biliary stones (2 patients), and biliary sludge (1 patient). Two patients (4.3%) had associated hepatic artery thrombosis. The bile leaks were diagnosed at a median of 29 days post-OLT (range, 2 to 65 days) and strictures at a median of 2 years (range, 33 days to 6.5 years) post-OLT. Before surgery, 25 patients (54%) underwent an attempt at radiological or endoscopic therapeutic intervention that failed. Median follow-up was 5 years (range, 9 months to 10 years). Early complications occurred in 12 patients (26%); the most common was chest infection (4 patients). There were 3 perioperative deaths (6%); 1 death was directly related to surgery. Late complications, mainly anastomotic strictures, occurred in 10 patients (22%), half of which were successfully treated by biliary balloon dilatation. The complication rate post-CDJ was less in those who underwent a failed nonsurgical approach than those proceeding straight to surgery (9 of 25 patients; 36% v 13 of 21 patients; 62%; P =.21, not significant). The procedure-related mortality for surgical revision of biliary complications after OLT is low, but early and late complications are common. A failed attempt at nonsurgical management does not increase the complications of reconstructive surgery. Strictures after CDJ should be considered for biliary balloon dilatation.

Biliary Tract Complications after Liver Transplantation: A Review

“…Larger leaks, particularly those associated with bilioenteric anastomosis, tend to be less amenable to non-operative treatment and immediate or early operative revision should be strongly considered [100, 108, 113, 114]. …”

“…Surgical revision and biliary reconstruction with the formation of a hepaticojejunostomy is indicated when endoscopic or percutaneous treatment fails. Recurrent anastomotic strictures following biliary reconstruction develop in around 20% of patients and can still be effectively treated by balloon dilatation and/or stenting [114, 121, 125, 126]. …”
