ABSTRACT
Objective To compare the effect of selective hepatic vascular exclsion ( SHVE) and total hepatic vascular exclusion ( THVE ) in the treatment of hepatic trauma with major hepatic vein injury. Methods A retrospective case control study was conducted to analyze the clinical data of 42 patients with hepatic trauma accompanied by hepatic vein injury admitted to multiple centers from April 2000 to December 2017. There were 30 males and 12 females, aged 14-65 years [(40. 2 ± 18. 8)years]. Blood flow exclusion was operated through HVE in 22 patients ( SHVE group ) and through THVE in 20 patients (THVE group). SHVE group included 22 patients (16 males and six females), aged (40. 1 ±19. 4)years. There were 10 patients with grade IV and 12 with grade V according to American Association of Traumatic Surgery ( AAST) classification of liver injury. In terms of the hepatic vein injury, there were 13 patients with type I, eight with type III, and one with type IV. THVE group included 20 patients (14 males and six females), aged (39.9 ±18.2)years. There were nine patients with grade IV and 11 with grade V according to AAST classification of liver injury. In terms of the hepatic vein injury, there were 11 patients with type I, seven with type III, and two with type IV. The operation approach, operation time, hepatic warm ischemia time, blocking time of hepatic vein blood flow, amount of abdominal hemorrhage, intraoperative blood loss, postoperative blood loss, intraoperative infusion, total blood transfusion, length of ICU stay after operation, length of hospital stay after operation, function of liver and kidney after operation, incidence of complications and mortality were compared between the two groups. Results There were no significant differences in the amount of abdominal hemorrhage, intraoperative blood loss, postoperative blood loss, perioperative blood transfusion, surgical procedure, and postoperative liver and kidney function between the two groups (P>0. 05). The THVE group had significantly longer operation time, hepatic warm ischemia time, hepatic venous blood flow blocking time, postoperative ICU time and postoperative hospital stay than the SHVE group (P<0. 05). The amount of infusion in the SHVE group was less than that in the THVE group (P <0. 05). The incidence of complications in SHVE group was 27％ (6/22), lower than that in THVE group [60％ (12/20)] (P<0. 05). The mortality of SHVE group was 14％ (3/22), lower than that of THVE group [45％ (9/20)] (P<0. 05). Conclusions SHVE and THVE can effectively control bleeding in the treatment of hepatic trauma with main hepatic vein injury. SHVE has more advantages over THVE in shortening operation time, warm ischemia time of liver, blocking time of hepatic vein blood flow, ICU stay after operation, hospital stay after operation and reducing intraoperative infusion volume, and can reduce the incidence of complications and mortality.
