肝门区肿瘤切除中肝脏血流阻断方法的探讨

目的 探讨肝脏血流阻断技术在肝门区肿瘤切除中的合理应用.方法 回顾性分析2005年1月至2008年3月采用第一肝门阻断法(Pringle法)和常温下全肝血流阻断技术(NHVE)相结合切除16例肝门区肿瘤的临床资料,分析肿瘤和肝门区血管的毗邻关系、阻断次数、阻断时间、术中出血量、输血量、术后并发症等指标.结果 本组16例患者采用Pringle法与NHVE相结合技术切除肿瘤,Pringle法平均阻断(3.8±1.6)次,平均阻断时间(46.6±28.8)min;NHVE平均阻断(1.6±0.4)次,平均阻断时间(23.5±8.2)min;术中出血量平均(1250±320)ml,输血量平均(860±245)ml;术中修补下腔静脉损伤4例,肝静脉损伤2例,门静脉主干损伤2例;术后均有肝脏酶学指标、胆线素不同程度的升高,经保肝等治疗后恢复正常,未发牛肝功能衰竭等严重并发症.结论 Pringle法与NHVE技术分步结合使用可减少全肝血流阻断时间、增加肝门区肿瘤切除的安全性.

Hepatic blood flow exclusion for resection of liver tumors involving hepatic hilar region

Objective To study hepatic blood flow exclusion for the resection of liver tumors involving hepatic hilar region. Methods The clinical data of 16 cases of liver tumors involving hepatic hilar region from January 2005 to March 2008 were retrospectively analyzed. Liver tumors were resected by the technique combining hepatic portal control ( Pringle's maneuver) and normothermie total hepatic vascular exclusion (NHVE). The relation of liver tumors to major vessels, episodes and durations of hepatic blood flow exclusion, intraoperative blood loss and blood transfusion, postoperative complications were analyzed. Results The technique combining Pringle's maneuver and NHVE was used in 16 cases. The mean episodes and durations of Pringle's maneuver were (3.8±1.6) min and (46.6±28.8) min, respectively. The mean episodes and durations of NHVE were (1.6±0.4) min and (23.5±8.2) min, respectively. The mean amount of intraoperativ blood loss was (1250±320) ml, blood transfusion (860±245) ml. Major hepatic vessel injuried were repaired intraoperatively including inferior vena cave in 4 cases, main hepatic veins in 2 cases and portal veins in 2 cases. The serum alanine transaminase(ALT) and bilirubin raised in different degrees after operation, and recovered gradually to normal level. There was no postoperative mortality and serious postoperative complications. Conclusions Alternative use of hepatic blood flow exclusion combining Pringle maneuver and NHVE reduces the time of total hepatic vascular exclusion, improves safety for resection of liver tumors involving hepatic hilar region.
