Abstract    Objective    To compare the clinical effects of selective hepatic vascular exclusion (SHVE) versus pringle maneuver (Pringle) in liver resections. Methods    Randomized controlled trial (RCT) reports on SHVE and Pringle in liver resections from May 1996 to July 2011 were collected from Medline, Elsevier, China National Knowledge Infrastructure (CNKI) ,  Wanfang databases and Pubmed. RevMan 5.1 software was used for data analysis. Results According to the included criteria, 9 clinical trials were selected finally. Blood loss of SHVE group was lower by 131.29mL than that of Pingle group (P<0.001). Operation time of SHVE was longer by 12.66 minutes than Pringle (P<0.05). Hospital stay of Pringle group was longer by 2.68 days than that of SHVE group (P<0.001). Hepatic failure and other complications（massive ascites，pleural effusion，lung infection and so on ）of SHVE were lower than those of Pringle (P<0.05). No significant difference was noted in bile leakage between 2 groups (P>0.05). Conclusion    SHVE is safe and feasible in liver resections. It helps more to reduce blood loss, hospital stay and incidence of live failure than the pringle maneuver.
