Perioperative analysis of laparoscopic liver resection with different methods of hepatic inflow occlusion

During liver resection, bleeding remains the most important challenge. A reduction in blood loss and avoiding the need for a blood transfusion are important objectives for liver surgeons today. The authors compared the intra- and postoperative course of patients undergoing laparoscopic liver resections under intermittent total pedicle occlusion (IPO), hemihepatic vascular occlusion (HVO), and selective vascular occlusion (SVO). Retrospective analysis was conducted of patient data from 41 cases of laparoscopic liver resection in three groups of patients under different occlusion methods, including 15 cases of IPO, 15 cases of HVO, and 11 cases of SVO. The advantages and disadvantages of the various methods were compared, as well as blood loss, operation time, changes in postoperative liver function, and complications. There was no operative death in any of the 41 patients. Generally, there was no significant difference among the three groups in blood loss, clamping time, or operative time. After the operation, the effect on liver function for the HVO and SVO groups was significantly less severe than that for the IPO group (P
