A Retrospective Analysis Of Laparoscopic Hepatectomy With Low Central Venous Pressure And Hepatic Blood Flow Occlusion

ObjectiveTo investigate the effects of low central venous pressure and hepatic blood flow occlusion on perioperative patient undergoing laparoscopic hepatectomy.MethodsData of 84 cases underwent hepatectomy laparoscopic from January 2017 to June 2019 were retrospectively analyzed.45 cases were treated with controlled low central venous pressure(LCVP group)and 39 cases were treated with uncontrolled central venous pressure(NCVP group).The time required for surgical resection of liver parenchyma,intraoperative blood loss,blood transfusion,postoperative liver function and hospital stay were compared to evaluate the effects of different techniques.ResultsThe median intraoperative blood loss,mean hepatectomy time and hepatic blood flow occlusion time in LCVP group were lower than those in NCVP group.There was no significant difference in the constituent ratio of postoperative complications between the two groups.The postoperative hospital stay in LCVP group was slightly lower,but there was no significant difference between the two groups(P>0.05),and there was no significant difference in liver function between the two groups(P>0.05).ConclusionThe application of low central venous pressure technique after hepatic blood flow occlusion can further reduce intraoperative blood loss and shorten operation time,and this technique is safe and effective,and the recovery level of liver function of postoperative patients is similar in two groups.
