采用改良式无血切肝术成功地为１０例肿瘤生长在第二肝门区的患者施行了肝叶切除手术。其中３例同时进行了下腔静脉壁损伤的修复。手术简便、实用，术后肝肾功能恢复较常规手术方法无明显差异，并就有关临床应用问题进行了讨论。 Successful hepatic lobectomy was performed in 10 patients with tumor growth in the second porta hepatis using an improved hepatocellular hepatectomy. Three of them were repaired at the same time by injury of the inferior vena cava wall. The operation is simple and practical, and the recovery of liver and kidney function after operation is not significantly different from conventional surgical methods. Discussions on clinical applications are discussed.
