Bypass reconstruction of hepatic artery using gastro-duodenal artery in radical operation for hilar cholangiocarcinoma / 中华肝胆外科杂志

ABSTRACT

Objective To summarize the clinical experience of hepatic artery bypass reconstruction using gastroduodenal artery in radical resection of hilar cholangiocarcinoma,and to provide assistance for surgeons applying artery reconstruction technique correctly in radical operation of hilar cholangiocarcinoma.Methods 9 cases of hilar cholangiocarcinoma with hepatic artery invasion wcrc subjected to radical resection combined with tumor invaded hepatic artery resection and reconstruction.Hepatic artery bypass reconstruction was performed by end-to end anastomosis,using the gastroduodenal artery interposition graft.The clinical data of these patients were reviewed retrospectively.Results All tumors of these cases with hilar cholangiocarcinoma were involved right hepatic artery,and the in volvement length was not less than 2 cm.The artery reconstruction was one-time successfully per formed in all cases.The median time required for anastomosis was (23.0±3.1) min.No postoperative complications,the dysfunction of gastrointestinal peristalsis or abnormal gastric drainage volume for example,related to the gastro-duodenal artery resection was observed.None of the patients devel oped any complications related to the arterial bypass reconstruction in the follow-up period,which was confirmed by abdominal CT scan.Conclusion Hepatic bypass reconstruction using gastro duodenal artery graft decreases the morbidity related to artery reconstruction and has little effect on gastrointes tinal function,which is the optimal choice for arterial reconstruction in radical operation for hilar cholangiocarcinoma.
