目的:比较3种解剖性血流阻断方案与对应的预阻断方案在肝脏肿瘤切除术中的应用价值,为肝切除术中最佳血流阻断方式的选择提供参考。方法:开展非随机同期对照试验,纳入240例肝脏肿瘤行开腹手术患者,划分为3个大组和6个小组,每小组各40例...目的:比较3种解剖性血流阻断方案与对应的预阻断方案在肝脏肿瘤切除术中的应用价值,为肝切除术中最佳血流阻断方式的选择提供参考。方法:开展非随机同期对照试验,纳入240例肝脏肿瘤行开腹手术患者,划分为3个大组和6个小组,每小组各40例:半肝血流阻断组(A1组)及预阻断组(A2组)、门静脉主干阻断组(B1组)及预阻断组(B2组)、保留半肝门静脉的肝门阻断组(C1组)及预阻断组(C2组),比较各组临床疗效。结果:(1)各直接阻断组与预阻断组比较,差异均有统计学意义(P<0.05):预阻断组术中出血量明显更少,术后输血例数明显更少,术后3 d凝血酶原活动度明显更高;(2)3个大组比较差异有统计学意义(P<0.05):接受输血患者术中,出血量按C1及C2、B1及B2、A1及A2组依次明显增加,术后通气时间按A1及A2、C1及C2、B1及B2组依次明显延长,术后3 d ALT及AST水平按B1及B2组、A1及A2组、C1及C2组依次明显增加。结论:3组解剖性血流阻断方案均有一定适用性,但通过血流预阻断技术均有助于控制术中出血,减少术后输血,促进肝功能恢复。展开更多
