 The present condition of endoscopic diagnosis of gastric submucosal tumor was studied. Materials are a group of 347 cases (354 lesions) found by endoscopic diagnosis, a group of 7 cases (7 lesions) found through endoscopic resection, and a group of 45 cases (45 lesions) found through surgical resection. The incidence is 1.4% in the endoscopic diagnosis group, 2.8% in the endoscopic resection group and 2.1% in the surgical resection group.

 Histological diagnosis confirmed inflammatory fibroid polyp and hamartomatous polyp in the endoscopic resection group. It confirmed leiomyosarcoma, leiomyoblastoma, leiomyoma, carcinoid, heterotopic pancreas, lipoma and inflammatory fibroid polyp in the surgical group.

 Regionally, the endoscopic diagnosis group showed many lesions in the lesser curvature of C, posterior wall of C and greater curvature of A and showed many myogenic tumors in the C, and many heterotopic pancreas in the A. The endoscopic resection group showed hamartomatous polyp in the C and inflammatory fibroid polyp in the A.

 The surgical group showed many lesions in the C (42.5%), in the M (40%), and showed many myogenic tumors and carcinoid in the C and M. It is possible to make a diagnosis of carcinod, heterotopic pancreas, and inflammatory fibroid polyp by biopsy and characteristic form.

 Most submucosal tumors associated with ulceration are diagnosable by biopsy. In case of submucosal tumor without ulcer formation, it is necessary to make an artificial ulcer and carry out biopsy. Most submucosal tumors which are more than 2 cm in diameter are to be understood as beeing myogenic tumors.

 The submucosal tumors which are more than 5 cm in diameter, or which are associated with ulcer, need surgery. The submucosal tumors which are less than 5 cm in diameter, and without ulceration, are to be kept under observation.
