 The diagnosis of Esophago gastric junctional cancer is difficult, because the cavity is narrow and inflammation is caused by gastric acid.

 Necessary for observation in the use of inhalation and exhalation, and the use of and right-and-left angle endoscopy.

 Attention must be paid to the surface and vascular patterns while using NBI magnified endoscopy to search for esophago gastric junctional cancer. There are some points that should be checked in the surface pattern, irregularity, fusion of pit-like pattern and villi-like pattern and density should be checked. And, there are some points to check for the differential diagnosis between cancer and inflammation in the vascular pattern, irregularity, running and fine network pattern.

 Attention must be paid to the oral margin because of the extension under the squamous epithelium.
