Background
The clinical impact of concomitant arterial resection and reconstruction for perihilar cholangiocarcinoma remains unclear. Microvascular anastomosis is typically used for arterial reconstruction, but we have proposed arterioportal shunting (APS) as an alternative procedure. The aims of this retrospective study were to evaluate concomitant arterial resection and reconstruction for perihilar cholangiocarcinoma patients, to evaluate the safety and survival impact of APS, and to evaluate whether APS offers a good alternative to microvascular reconstruction.
Patients and Methods
Thirty-nine patients with perihilar cholangiocarcinoma who required arterial reconstructions were retrospectively evaluated.
Results
No significant difference was seen in overall incidence of postoperative complications between groups, but the incidence of liver abscess formation was significantly higher in the APS group. The cumulative 5-year survival rate was 15 % in patients undergoing concomitant arterial resection and reconstruction for perihilar cholangiocarcinoma. No significant differences in survival were identified between the microvascular (MV) and APS groups. Cumulative 5-year survival rates were 18 % in the MV group and 11 % in the APS group.
Conclusion
Concomitant arterial resection and reconstruction are feasible for patients with perihilar cholangiocarcinoma. Microvascular reconstruction should be used as the first-line strategy for these patients, with APS indicated only when the artery is unable to be microscopically anastomosed.
