食管外科手术并发症的定义和分级以及预测

Definition, classification and prediction of complications ;related to esophageal resection

食管切除术是众多食管疾病的主要治疗方式，但也是风险极高的手术之一。因此，降低食管切除术后的病死率与并发症发生率是值得关注的问题，其中对食管外科并发症的定义、分级和预测是食管外科的重要内容。然而，目前尚缺乏对食管外科并发症的统一定义及其严重程度的分级，也无专门针对食管切除术后并发症的预测系统。了解这方面的研究进展对我们预测食管手术的死亡风险、预防并发症的发生及治疗有重要意义。

Esophagectomy is the major treatment for a variety of esophagus diseases. However, despite its wide applications, it is also one of the highest-risk procedures. Thus, reduction of mortality and complication after esophagectomy has drawn much attention, and the definition, classification and prediction of complication following esophagectomy is of vital importance. Unfortunately, there is no unified definition and specific prediction system for complications of esophagectomy until now. We review the＆amp＇advances in complication research in order to offer references to reduce mortality, prevent or treat complications of this high-risk operation.
