绕肝提拉法在正中裂劈开肝脏切除中的意义

The significance of liver hanging maneuver in liver-splitting anterior approach for hepatectomy

目的探讨在肝后下腔静脉和肝脏之间建立隧道、放置绕肝带的可行性以及绕肝提拉法在经正中裂劈开断肝中对于下腔静脉的保护和肝内管道显露的作用。方法对47例肝脏切除患者钝性分离肝后下腔静脉前的间隙,建立肝后隧道并且预置绕肝带。必要时放置止血板。切肝时提拉绕肝带使肝脏与下腔静脉之间产生距离,从而有效保护下腔静脉,并且使手术视野暴露更佳。结果47例患者成功建立了肝后隧道并预置绕肝带,未出现与本操作相关的严重并发症,1例因为渗血较多中止建立肝后隧道。结论肝后隧道的建立和绕肝带的放置在解剖和技术上是可行的;绕肝提拉法对于下腔静脉的保护和肝切除术中肝内管道的显露有较好的效果。

Objective To analyze the feasibility of developing a tunnel between infenor vena cava （IVC） and caudate lobe before passing a tape through it, and to explore the significance of liver hanging maneuver in liver-splitting anterior approach for hepatectomy. Methods Blunt dissection was used to develop the tunnel before a tape was passed through. A hemostatic plate was placed on the surface of liver parenchyma if needed. In the procedure of hepatectomy, the tape was pulled up to create an interspace between liver parenchyma and IVC so that the IVC can be protected during transection. Results Liver hanging maneuver was performed successfully in 47 cases. There were no severe complications related to the procedure in these cases. The procedure was terminated in 1 case because of severe bleeding. Conclusions 1. Liver hanging maneuver is feasible in terms of anatomy and technique. 2. With liver hanging maneuver, IVC can be protected safely and the intrahepatic vessels and ductal system at the transaction line can be exposed clearly. It also makes anterior approach for hepatectomy safer and easier.
