[Definition, classification and prediction of complications related to esophageal resection].

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 advances in complication research in order to offer references to reduce mortality, prevent or treat complications of this high-risk operation.
