Objective To explore the safety and feasibility of using modified Glisson pedicle transection methodin the precise hepatectomy of hepatocellular carcinoma （HCC）. Methods Sixty patients with HCC， which confirmed by postoperational pathology were admitted in the study. During the surgery of experimental group （Glisson group）， the segment pedicle were transected firstly using modified Glisson pedicle transection method. Then， the liver parenchyma was split follow the hepatic vein guided by intraoperative ultrasound. During the surgery of contrast group （Prigle group），the liver parenchyma was split using ultracision harmonic scalpel under intermittent pringle clamping of hilar. Results There were no significant difference in the amount of intraoperative bleeding， blood transfusion， as well as duration of surgery， serum alanine aminotransferase， total bilirubin， and length of hospital stay between the two groups （P＞0.05）. However， the incidence of postoperative complication was lower in Glisson group （23.3% vs. 50.0%， P＜0.05）. In addition， the length of tumor margin was more favorable in Glisson group 〔（2.3±0.7） cm vs. （1.5±0.6） cm， P＜0.05〕. The recurrence rate of Glisson group was lower than that Prigle group， but was not different significantly （P＞0.05）. Conclusions The modified Glisson pedicle transection method has the same safety as traditional method in the precise hepatectomy of HCC. And it has the advantages in lower postoperative complication and more favorable tumor margin， which may reduce the recurrence rate theoretically.
