肝切除术后肝功能衰竭的危险因素

Risk factors of liver failure after hepatectomy

随着肝脏外科技术的发展,围手术期管理和患者筛选标准的进步使可以接受半肝切除术或扩大肝切除术的患者数量大大增加.而肝切除术后肝功能衰竭是肝切除术后严重的并发症之一,肝切除术后肝功能衰竭患者相关风险中糖尿病及已有肝脏疾病如肝硬化、脂肪肝、胆汁淤积等是最重要的危险因素.手术相关风险中残肝体积及术中大出血是影响肝切除术后肝功能衰竭发病率及病死率的关键因素.而到目前为止还没有很好的方法治疗肝功能衰竭,所以预防显得尤为重要.

Advances in hepatic surgical technique,perioperative care and improvements in patient selection criteria have increased the number of patients who could undergo major or extended hepatectomy with curative intent.Posthepatectomy liver failure （PHLF） is one of the most serious complications after liver resection.Different risk factors are related to the occurrence of PHLF,among surgery-related factors,massive bleeding and remnant liver volume were related to higher frequency of PHLF.The presence of diabetes and liver disease such as cirrhosis,cholestasis,steatosis had been involved with the occurrence of PHLF.So far there is no good method for the treatment of PHLF,so prevention is very important.
