Outcomes of side-to-side conversion hepaticojejunostomy for biliary anastomotic stricture after right-liver living donor liver transplantation.
Hepatobiliary & Pancreatic Diseases International : HBPD INT 2013 Februrary
BACKGROUND: Conversion hepaticojejunostomy is considered the salvage intervention for biliary anastomotic stricture, a common complication of right-liver living donor liver transplantation with duct-to-duct anastomosis, after failed endoscopic treatment. The aim of this study is to compare the outcomes of side-to-side hepaticojejunostomy with those of end-to-side hepaticojejunostomy.
METHODS: Prospectively collected data of 402 adult patients who had undergone right-liver living donor liver transplantation with duct-to-duct anastomosis were reviewed. Diagnosis of biliary anastomotic stricture was made based on clinical, biochemical, histological and radiological results. Endoscopic treatment was the first-line treatment of biliary anastomotic stricture.
RESULTS: Interventional radiological or endoscopic treatment failed to correct the biliary anastomotic stricture in 13 patients, so they underwent conversion hepaticojejunostomy. Ten of them received end-to-side hepaticojejunostomy and three received side-to-side hepaticojejunostomy. In the end-to-side group, two patients sustained hepatic artery injury requiring repeated microvascular anastomosis, two developed re-stenosis requiring further percutaneous transhepatic biliary drainage and balloon dilatation, and two required revision hepaticojejunostomy. In the side-to-side group, one patient developed re-stenosis requiring further endoscopic retrograde cholangiography and balloon dilatation. No re-operation was needed in this group. Otherwise, outcomes in the two groups were similar in terms of liver function and graft survival.
CONCLUSIONS: Despite the similar outcomes, side-to-side hepaticojejunostomy may be a better option for bile duct reconstruction after failed interventional radiological or endoscopic treatment because it can decrease the chance of hepatic artery injury and allows future endoscopic treatment if re-stricture develops. However, more large-scale studies are warranted to validate the results.
