尽管近年来对原发性肝癌(PHC)的治疗已有许多进展,但肝切除的手术死亡率仍有6.1～12.6%,而仅作肝动脉结扎术的死亡率高达9～18%。肝功能衰竭是木后的重要死亡原因,在切除病例的死因中占33.9%。除技术操作原因外,这显然与存在的肝病背景、肝功能损害程度、切除肝实质的量以及肝脏的储备能力和再生能力等有着密切的关系。因此,如能在手术前、后,对这些影响手术死亡率的因素作出某些预测,将具有重要的意义。为说明方便,本文将近年来采用的某些预测方法略加归类,从以下两大方面进行介绍。有肝病背景者的手术风险预测 PHC常伴有肝病背景包括肝硬化(50～80%)、门脉高压(50%)、慢性肝炎或纤维变性(25%)以及食管 Although there have been many advances in the treatment of primary liver cancer (PHC) in recent years, the surgical mortality rate of liver resection remains 6.1 to 12.6%, and the mortality rate for hepatic artery ligation alone is as high as 9 to 18%. Liver failure is an important cause of death after wood, accounting for 33.9% of deaths in cases of resection. In addition to the technical operation reasons, this is obviously related to the existence of liver disease background, the extent of liver damage, the amount of liver parenchyma removed, and the ability of the liver to reserve and regenerate. Therefore, it would be of great significance to make certain predictions of these factors that affect operative mortality before and after surgery. For ease of explanation, this article will categorize some of the forecasting methods used in recent years, and will introduce the following two aspects. Surgical Risk Prediction for People with Liver Disease Background PHC is often associated with liver disease background including cirrhosis (50-80%), portal hypertension (50%), chronic hepatitis or fibrosis (25%), and esophageal tract
