Recent improvements in perioperative morbidity and long-term outcome following liver surgery have led surgeons to attempt larger and more technically challenging liver resections. Total vascular exclusion (TVE) of the liver during resection has been proposed as a technique that will facilitate these difficult resections while minimizing blood loss. Total vascular exclusion is performed by obtaining complete isolation of the vascular pedicle of the liver. Once the hepatic vein is clamped, rapid resections may be performed with a loss of only the blood volume contained within the liver itself. Safe performance of total vascular exclusion of the liver requires a thorough understanding of hepatic anatomy, patient selection criteria, and the physiologic changes incurred by hepatic exclusion and subsequent ischemia and reperfusion. The following report discusses these issues, gives a detailed description of the steps involved in obtaining safe total vascular exclusion, and presents a technique using rapid parenchymal excision with a scalpel and capsular compression to obtain hemostasis and prevent bile leaks. We briefly discuss our experience with 144 consecutive resections in which this technique was used.
近期肝脏手术围手术期发病率及长期预后的改善,促使外科医生尝试进行更大且技术难度更高的肝脏切除术。肝切除术中的全肝血管阻断(TVE)已被提出作为一种有助于进行这些困难切除术并使失血降至最低的技术。全肝血管阻断通过完全隔离肝脏血管蒂来实施。一旦肝静脉被夹闭,即可进行快速切除,此时仅丢失肝脏自身所含的血容量。安全实施全肝血管阻断需要全面了解肝脏解剖结构、患者选择标准以及肝阻断及随后的缺血和再灌注所引发的生理变化。以下报告将讨论这些问题,详细描述实现安全全肝血管阻断所涉及的步骤,并介绍一种使用手术刀快速实质切除及包膜压迫来实现止血和防止胆漏的技术。我们简要讨论了连续144例使用该技术的切除术的经验。
