Abstract
Purpose
This retrospective study aimed to clarify whether the postoperative prognosis differs between right and left hepatectomy for Bismuth type I/II perihilar cholangiocarcinoma.
Methods
Preoperative images of 195 patients with perihilar cholangiocarcinoma were reexamined. Patients with Bismuth type I/II perihilar cholangiocarcinoma without a difference in extraductal tumor invasion between the right and left sides of the hepatic portal region were classified into those undergoing left (L group) or right (R group) hepatectomy.
Results
Twenty-three patients (11.8%) were classified into the L group and 33 (16.9%) into the R group. All eight patients with pTis/1 belonged to the L group. The L group had significantly less liver failure than the R group (p = 0.001). One patient (4.3%) in the L group and four patients (12.1%) in the R group died from postoperative complications. Among 48 patients with pT2, the L group tended to have better overall survival (median, 12.2 vs. 5.6 years; p = 0.072), but not recurrence-free survival (median, 9.1 vs. 3.6 years; p = 0.477), in comparison to the R group.
Conclusions
Postoperative survival after left hepatectomy for Bismuth type I/II perihilar cholangiocarcinoma is expected to be as long as that after right hepatectomy.
