ABSTRACT
Objective@#To compare the safety and efficacy of the retrograde and the antegrade techniques in laparoscopic left hemihepatectomy.@*Methods@#Of the 65 patients who underwent laparoscopic left hemihepatectomy between January 2016 to June 2018 at the Ningbo Li Huili Hospital of Medical Center, retrograde left hemihepatectomy was carried out in 31 patients, and antegrade left hemihepatectomy in 34 patients. The perioperative data, duration of operation, intraoperative blood loss, postoperative complications (including major bleeding, abdominal abscess and bile leakage), and post-operative hospital stay were retrospectively compared between the two groups.@*Results@#There were no significant differences in the perioperative general status between the two groups (P>0.05). Both the duration of operation [(121.5±22.1) min vs. (190.9±48.9) min, P<0.05] and the amount of blood loss [(118.9±84.1) ml vs. (195.2±85.4) ml, P<0.05] were significantly less in the retrograde than the antegrade group. There were no statistical differences in the incidences of major complications such as post-hepatectomy hemorrhage, abdominal abscess, or bile leakage, and in the postoperative hospital stay [(10.0±2.8) d vs. (12.2±3.4) d, P>0.05].@*Conclusions@#Occlusion of hepatic vascular inflow and outflow combined with retrograde left hemihepatectomy was safe and feasibly. The retrograde approach was superior to the antegrade approach in laparoscopic left hemihepatectomy.
