Effects of hepatic segmentectomy without hepatic blood inflow occlusion on hepatic function of patients with hepatocellular carcinoma / 中华消化外科杂志

ABSTRACT

Objective To investigate the safety and technique of hepatic segmentectomy without hepatic blood inflow occlusion.and to detect its influences on the function of the remnant liver and postoperative complications.Methods The clinical data of 37 hepatocellular carcinoma patients who had undergone hepatic segmentectomy without hepatic blood inflow occlusion(group A)in Tonal Hospital from December 2006 to December 2007 were retrospectively analyzed.The clinical data of 3 1 patients who were treated by hepatic segmentectomy with Pringle maneuver(group B)during the same period of time were used as control.The efficacy of the 2 treating methods was analvzed bv chi-square test and t test.Results The difference of perioperative blood losses between group A[(400±100)ml]and B[(350±100)ml]had statistical significance(t=0.717,P＞0.05).The time of alanine transaminase returning to the normal level in group A was(6±2)days,which was significantly shorter than(10±3)days in group B(t=6.006,P＜0.05).The postoperative complication rates of group A and B were 14%(5/37)and 35%(11/31),respectively,with statistical difference between the 2 groups(t=4.525.P＜0.05).Conclusions Hepatic segmentectomy without hepatic blood inflow occlusion can effectively prevent the hepatic ischemia reperfusion injury and reduce the postoperative complications.
