Background  Significant hemorrhage together with blood transfusion has negative impact on postoperative morbidity, mortality, and long-term survival of liver resection. Various techniques of vascular occlusion have been developed to reduce intraoperative blood loss. The objective of this study was to compare the outcomes of Pringle maneuver, hemi-hepatic vascular occlusion, and treatment without vascular occlusion used during liver resection.    Method  Data of 574 patients with Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), who underwent major hepatectomy between January 2009 to March 2013 by Pringle maneuver (N = 158), hemi-hepatic vascular inflow occlusion (N = 216), or without any vascular occlusion (N = 200), were included in this retrospective study. Perioperative blood transfusion, intraoperative blood loss, and postoperative liver function, and surgical complications were analyzed and compared between the three groups.    Result  There were no significant difference observed in postoperative bilirubin, liver enzyme, and albumin levels between three groups (P&gt;0.05). 5 patients (2.5%) in no occlusion group, 2 (1.3%) in Pringle group, and 8 (3.7%) in hemi-hepatic group had liver failure; but, there were no differences (P&gt;0.05). The overall postoperative complications rate between three groups did not reach significant differences (33.5% vs 34.2% vs 42.6%, respectively; P&gt;0.05). However, significant differences in intraoperative blood loss between no occlusion group (638.2±426.8 ml) and Pringle group (518.0±451.0 ml) or hemi-hepatic group (513.0±366.7 ml) (P&lt;0.01).    Conclusion  Although there were no differences found between three groups regarding postoperative complications rate, no vascular occlusion group had more blood loss than the other two groups during liver resection.
