[Study of bloodless hepatectomy under occlusion of total hemi-hepatic vessel].

ABSTRACT

OBJECTIVE: To explore the preliminary clinical evaluation of hepatectomy with total hemi-hepatic vascular exclusion. METHODS: Twenty-eight patients with primary liver cancer were divided into two groups of hepatectomy with total hemi-hepatic vascular exclusion (group A) and total hepatic inflow occlusion (group B). The time of hepatic vascular control, intraoperative blood loss, volume of removed liver, postoperative liver function recovery and complications were compared between the two groups. RESULTS: The intraoperative blood loss in group A was (296 +/- 240) ml, which was less significantly than that in group B [(582 +/- 497) ml] (P<0.05). The serum pre-albumin levels on the day 1, 3 and 7 after operation in group A were (164 +/- 39) mg/L, (111 +/- 17) mg/L and (104 +/- 23) mg/L, which were higher significantly than that in group B [(134 +/- 34) mg/L, (90 +/- 22) mg/L and (82 +/- 35) mg/L] (P<0.05). While the time of hepatic vascular control and volume of lost liver were no difference between the groups (P>0.05). There were no significant difference in other items between the groups. CONCLUSIONS: Intraoperative blood loss and liver damage of hepatectomy under the total hemi-hepatic vascular exclusion could be less than that under the other methods of vascular occlusion. It could be worth improving and applying further.
