双绕肝提拉在规则性右半肝切除中的应用

目的 介绍我们使用双绕肝提拉法施实规则性右半肝切除术的经验.方法 24例病人施行了双绕肝提拉前入路法右半肝切除,以49例采用传统方法行右半肝切除的病人作为对照组,分析了双绕肝提拉法的优势.结果 27例病人成功建立肝后下腔静脉隧道,其中24例病人通过双绕肝提拉法行规则右半肝切除,3例病人因肿瘤接近正中裂而放弃双绕肝法.与对照组比较,使用双绕肝提拉法的病人术中出血量少(t=3.191,P＜0.05),术后ALT恢复快(t=2.398,P＜0.05)、肝功能Child分级好(χ2=9.31,P＜0.05).两组病人手术时间无明显差异(t=-1.695,P＞0.05).绕肝带提拉肝脏后,由于肝后下腔静脉与肝脏之间产生1～2 cm的间隙,故切肝时无一例损伤肝后下腔静脉及肝静脉.结论 双绕肝提拉前入路法能提高规则右半肝切除的安全性及成功率.

Application of double liver hanging maneuver in anatomical right Hemihepatectomy

Objective To introduce the application of double liver hanging maneuver in anatomical right hemihepatectomy and share our own experience. Methods Twenty-four patients underwent right hemihepatectomy using double liver hanging maneuver, and the data were collected prospectively after operation. Another 49 patients underwent right hemihepatectomy using the traditional methods,serving as the control group. Results Retrohepatic tunnel was constructed in 27 patients, double liver hanging maneuver was successfully performed in 24 anatomical right hemihepatomy and failed in 3 patients due to the near proximity between the tumor and the middle line. Compared with the control group, blood loss was much less (t=3. 191 ,P＜0.05), ALT and liver function recovered more quickly postoperatively and the difference in operative duration between the 2 groups was not significant (t=-1. 695,P＞0. 05). There was about 1-2 cm wide space located between retrohepatic IVC and dorsal liver when the 2 tapes were tracted, and no injury in hepatic short veins and retrohepatic IVC occurred during the operation. Conclusion The double liver hanging maneuver can make anatomical right hemihepatectomy more accessible and safe.
