 Magnification endoscopes that come up to the level of conventional endoscopes in handling ease have been developed in recent years, and magnification endoscopy has become widely used in the upper gastrointestinal tract. The usefulness of magnification endoscopy has often been reported in the diagnosis of gastric cancer and in the determination of its extent, but with regard to the determination of its depth of invasion, the usefulness is controversial. We investigated the relationship between the magnification findings and depth of invasion. We often observed intramucosal cancer with small regular pattern and submucosal cancer with lack of visible structure in differentiated carcinoma, and carcinomas with dilated vessels often invasive to the submucosal layer. This indicates that magnification endoscopy may help determine the depth of invasion of gastric cancer.
