Despite the ongoing decades-long controversy, Pringle maneuver (PM) is still frequently used by hepatobiliary surgeons during hepatectomy. The aim of this study was to investigate the effect of PM on intraoperative blood loss, morbidity, and posthepatectomy hemorrhage (PHH). A series of 209 consecutive patients underwent extended hepatectomy (EH) (≥5 segment resection). The association of PM with perioperative outcomes was evaluated using multivariate analysis with a propensity score method to control for confounding. Fifty patients underwent PM with a median duration of 19 minutes. Multivariate analysis revealed that risk of excessive intraoperative bleeding (≥1500 ml; odds ratio [OR] 0.27, 95%-confidence interval [CI] 0.10–0.70, p = 0.007), major morbidity (OR 0.41, 95%-CI 0.18–0.97, p = 0.041), and PHH (OR 0.22, 95%-CI 0.06–0.79, p = 0.021) were significantly lower in PM group after EH. Furthermore, there was no significant difference in 3-year recurrence-free-survival between groups. PM is associated with lower intraoperative bleeding, PHH, and major morbidity risk after EH. Performing PM does not increase posthepatectomy liver failure and does not affect recurrence rate. Therefore, PM seems to be justified in EH.
