Effect of arterioportal shunting in radical resection of hilar cholangiocarcinoma

<正> Background The resection and reconstruction of the hepatic artery is often required in radical surgery for hilarcholangiocarcinoma.In this study,we report our experience in performing artenoportal shunting as an alternative for thearterial reconstruction.Methods Four patients with hilar cholangiocarcinoma underwent extended left hepatectomy and caudate lobectomycombined with en bloc resection of the hepatic artery and artenoportal shunting with restriction of the arterial caliber.Theefficacy of artenoportal shunting was assessed by computed tomography angiography (CTA).Results All the four patients recovered uneventfully without any complications.CTA showed a patent shunt and normalliver regeneration.No signs of portal hypertension were found at one year of follow-up.Conclusions Arterioportal shunting with restriction of the arterial caliber appears to be a feasible and safe alternativefor the microvascular reconstruction after hepatic artery resection in radical surgery for hilar cholangiocarcinoma.
