title: Diagnosis of submucosal tumors by injecting a water soluble contrast medium: diagnosis of extra-gastric tumors and gastric varices.
abstract: Extra-gastric compression caused tumescent lesions that are difficult to differentiate from gastric submucosal tumors, and gastric varices similar in appearance to circumscribed tumors were sometimes experienced clinically. Up to now, the differential diagnosis of these lesions has been done by the palpation through x-ray examination or the tactile test under endoscopic examination. Even by the recent use of the CT scan, the differential diagnosis still remains unsatisfactory except in a few specific cases. Under these present circumstances, submucosography is recommended for routine screening test for outpatients. Our method is simple, safe and time-saving. Recently, it has become easy to diagnose hemangiomas as well as varices in the stomach by application of submucosography. Accordingly, in the cases of vascular tumors or tumescent lesions caused by extra-gastric compression, the risk of incidental major bleeding or perforation can be prevented by using the submucosography.
