摘要：

食管胃结合部癌的定义，通常参照Siewert分型和日本的Nishi分型。在第10版日本《食管癌处理规约》中，食管胃结合部被定义为食管肌层和胃肌层之间的边界，但由于肌层难以确定，食管胃结合部的具体判断方法尚不明确。本文主要介绍食管胃结合部的内镜、上消化道造影及病理组织学判断标准，旨在通过明确正常状态下食管胃结合部的确定标准，进而建立针对Barrett食管、食管胃结合部癌浸润状态下的食管胃结合部的综合判定方法，以指导食管胃结合部疾病的临床诊断和食管胃结合部癌的手术方式选择。

关键词：食管胃结合部癌；食管胃结合部；Siewert分型

Abstract：

The classification of esophagogastric junction (EGJ) cancer is usually divided into the Siewert classification or the Nishi classification in Japan. In the 10th edition of the Japanese classification of esophageal cancer, the EGJ was explicitly defined as the boundary between the muscular layer of the esophagus and gastric. However, due to the difficulty in identifying the muscular layer, the specific diagnostic methods of EGJ are still unclear. This article mainly introduces the endoscopic, upper gastrointestinal radiography and pathological diagnostic criteria for the EGJ. It aims to establish clear criteria for identifying the normal EGJ and to develop comprehensive assessment methods for determining the EGJ location in cases involving Barrett's esophagus or EGJ cancer infiltration. Ultimately, this work aims to guide the clinical diagnosis of EGJ disorders and inform the selection of surgical approaches for EGJ cancer.

Key words：Esophagogastric junction carcinoma; Esophagogastric junction; Siewert classification
