ABSTRACT
Objective To investigate the efficacy of precise hemihepatectomy guided by middle hepatic vein(MHV),and to study the value of preoperative hepatic vein evaluation.Methods The clinical data of 68 patients who received hemihepatectomy at the Nanjing Drum Tower Hospital from October 2007 to September 2009were prospectively studied.Of the 68 patients,30 received precise hemihepatectomy guided by MHV(precise group)and 38 received anatomical hemihepatectomy(traditional group).The types of hepatic vein in the precise group were evaluated and classified preoperatively.The operation time,operative blood loss,volume of blood transfusion,liver function,morbidity and length of hospital stay of the 2 groups were compared.All data were analyzed using the t test,rank sum test,chi-square test and Fisher exact probability.Results According to the Nakamura's classification,there were 17(57%)patients with type Ⅰ,8(27%)with type Ⅱ and 5(16%)with type Ⅲ;according to the Kawasaki's classification,there were 11 patients with type Ⅰ(37%)and 19 with type Ⅱ(63%).There were 13 patients received right hepatectomy with MHV preservation,15 received left hepatectomy with MHV preservation,1 received right hepatectomy without MHV preservation and 1 received left hepatectomy without MHV preservation.There were no significant difference in the volume of operative blood loss and blood transfusion,level of alanine transaminase,total bilirubin,cholinesterase at postoperative day 3,total length of hospital stay and length of postoperative hospital stay between the 2 groups(t = 1.07,0.92,0.07,0.21,0.63,0.63,0.75,P > 0.05).The operation time,levels of albumin at postoperative day 3 and complication rate were (342 ± 113)minutes,(35 ±3)g/L and 40%(12/30)in the precise group,and(270 ±73)minutes,(33 ±3)g/Land 66%(25/38)in the traditional group,respectively,with significant differences between the 2 groups(t =2.79,2.19;x2 =4.49,P<0.05).The positive rates of the resection margin were 5%(1/19)in the precise group and 35%(8/23)in the traditional group,there was a significant difference between the 2 groups(P <0.05).ConclusionPreoperative hepatic vein evaluation and precise hemihepateetomy guided by MHV can preserve the functional liver tissues with venous drainage,achieve adequate tumor-free resection margin and reduce the postoperative complication rate.
