Summary: | Preoperative biliary drainage (PBD) followed by portal vein embolization (PVE) has increased the chance of resection for hilar cholangiocarcinoma (CCC). We aim to identify the optimal timing of PVE after PBD in patients undergoing hepatectomy for hilar CCC.
We retrospectively reviewed 64 patients who underwent hepatectomy after PBD and PVE for hilar CCC. The patients were classified into 3 groups: Group 1 (PBD-PVE interval ≤7 days), Group2 (8–14 days) and Group 3 (>14 days). The primary end points were 90 days mortality and grade B/C posthepatectomy liver failure (PHLF).
There was no significant difference in primary end points between three groups. A marginally significant difference was found in the incidence of Clavien-Dindo grade ≥3 complications and wound infection (57.1% vs 38.1% vs 72.4%, p = 0.053 and 21.4% vs 38.1% vs 55.2%, p = 0.099). In multivariable analysis, Bismuth type IIIb or IV was independent risk factors for grade B/C PHLF (HR: 4.782, 95% CI 1.365–16.759, p = 0.014).
Considering that the PBD-PVE interval did not affect PHLF, and the surgical complications increased as the interval increases, PVE as early as possible after PBD would be beneficial. |
