Methods: 1. Experimental laparoscopic liver resection: We selected pigs as experimental models aiming to approach human beings physiological and anatomical condition. After CO2 pneumoperitoneum was established, the ligaments around liver were dissociated. Livers were cut off by the methods such as clamp dissection, microwave tissue coagulator, ultrasound dissector, Ligsure dissection, hand-assisted, short abdominal incision laparoscopy-assisted, and Endo-GIA switcher. The operation time and bleeding volume were compared between different methods of laparoscopic liver resection. The advantages and limitations of different methods were summarized. 2. Clinical laparoscopic liver resection: 15 cases with tumors in segment V of anterior right lobe or segments II, III of left lateral lobe or segment IV of left internal lobe were selected in this study. The liver diseases included hepatocellular cancer, hepatic cavernous hemangioma and hepatic focal nodular hyperplasia. The ligaments around liver were dissociated after CO2 pneumoperitoneum established. Laparoscopic liver resection were carried out by some of the methods combined such as clamp dissection, microwave tissue coagulator, hand-assisted, short abdominal incision laparoscopy-assisted, ultrasound dissector, rotation and suction dissector.

1、实验性腹腔镜肝切除：以猪为实验动物，旨在接近人体的生理、解剖环境下进行实验，建立操作空间后游离肝脏周围韧带，采用钳夹分离切肝法、微波刀切肝法、超声刀切肝法、Ligsure切肝法、手辅助腹腔镜肝切除法、小切口腹腔镜辅助切肝法、Endo-GIA切肝法等方法实施腹腔镜下肝切除，比较不同切肝方法的手术时间、出血量，总结各种方法的优越性及其局限性。2、临床腹腔镜肝切除：选择肿瘤位于肝右前叶第Ⅴ段、肝左外叶第Ⅱ、Ⅲ段及左内叶第Ⅳ段的15例患者，病种包括原发性肝癌、肝海绵状血管瘤、肝脏局灶性增生，建立气腹后游离肝脏周围韧带，采用钳夹分离断肝、微波刀固化后断肝、手辅助腹腔镜肝切除、小切口腹腔镜辅助肝切除、超声刀断肝、旋吸断肝等多种方法分离切线肝组织，暴露管道结构，再采用高频电凝、钛夹夹闭、缝扎止血、止血纱布覆盖、氩气刀止血、生物胶止血、Endo-GIA处理等多种方法相结合处理肝断面，统计手术完成情况、手术时间、手术出血量、术后并发症及术后住院时间等，评价腹腔镜肝切除的可行性及安全性。
