Abstract:
Objective To explore causative factors, and prevention and treatment of nonanastomotic biliary stricture (NABS) after orthotopic liver transplantation. Methods The donor’s liver together with celiac artery and its branches were havvested rapidly without injury to reduce heat ischemia time and artery loss, then the bilinary duct was flushed to clean out residual bile. During operation, when the portal vein was opened, the hepatic artery of the donor liver was flushed with heparin saline. Post-operatively, acute or chronic rejection and cytomegalovirus infection should be prevented. When NABS occurred, it was treated with bilinary balloon dilatation. Results Of 36 patients with liver transplantation, 4 patients (11.1%, 4/36) were found to suffer from NABS. Two patients were cured, in one patient it was improved after dilatation, and one patient died. Conclusion NABS is mainly related to artery loss, cold/warm ischemia injury, ischemia/reperfusion injury, bile toxicity injury, immune injury and cytomegalovirus infection etc. Biliary balloon dilatation is the major treatment for NABS. Retransplantation is necessary for some severe cases.
