Abstract Background The aim of this trial was to compare the efficacy and safety of BiClamp forceps with the “gold‐standard” clamp‐crushing technique for open liver resection. Methods From October 2014 to May 2016, 86 consecutive patients scheduled to undergo hepatic resection were randomized to a BiClamp forceps group ( n = 43) or to a clamp‐crushing technique group ( n = 43). Results Background characteristics of the two groups were closely matched. There were no significant differences between the BiClamp forceps group and clamp‐crushing group in total intraoperative blood loss (339.81 ± 257.20 ml vs. 376.73 ± 303.67 ml, respectively; P = 0.545) or blood loss per transection area (5.35 ± 3.27 ml/cm 2 vs. 5.44 ± 3.02 ml/cm 2 , respectively; P = 0.609). Liver transection speed, the need of blood transfusion, morbidity, length of postoperative hospital stay, total hospitalization cost and liver function recovery were similar in the two groups. Multivariate logistic regression analysis identified major hepatectomy, multiple resections and liver transection time ≥30 min as significantly unfavorable factors for decreased intraoperative blood loss. Conclusions Liver parenchymal transection with BiClamp forceps is as safe and feasible as the gold‐standard clamp‐crushing technique.
