Abstract
Carcinomas of the EGJ are located at the thoracoabdominal border between esophagus and the stomach. This entity of the disease includes not only the true EGJ carcinoma, but also distal esophageal and upper pole of the gastric carcinoma. There are two major histopathological types of carcinomas located at the EGJ; adenocarcinoma and squamous cell carcinoma. However, surgical strategy for carcinoma of the EGJ should be determined not by histopathology of the tumor, but by tumor location and invasion of the esophageal and gastric wall and the relative risk of mediastinal lymph node metastasis. Esophageal invasion length (EIL) and gastric invasion length (GIL) should be determined and can be used for deciding the range of esophageal or gastric resection and area of dissecting lymph node. Abdominal, transhiatal, and transthoracic approaches are selected according to preoperative diagnosis and oncological safety.
