A NEWAPPROACH IN THE DIAGNOSIS OF THE SUBMUCOSAL TUMOR

Abstract

A method is developped in this medical department to delineate the outline of the submucosal lesion. In this method, one to 3ml of contrast media, either 60% Conray or 64.9% Conraxin mixed with a small amount of 5 % patent Blue-V solution, is injected through specially made needle of 0.5mm in diameter into the submucosal space approximate to the oral and anal aspects of the root of the lesion using fibergastroscope designed for biopsy. This is followed by direct X-ray examination and simple lateral and P-Apictures were taken. These pictures are analyzed and divided into two groups. The diffuse type shows diffusely dispersed contrast media and the defect type demonstrates clearly delineated outline of the tumescent lesion. The defect type picture is the characteristic finding of the submucosal tumor. So far until the time of the present report, 100 clinical experiences were accumulated without any complications. Iodine sensitive cases should not be subjected to this method and injection of contrast material to the cancerous area should alone be avoided. The method can be performed without much hazards and each illustrative cases will be demonstrated. The method is combine with the thorny needle biopsy technique and some promising results in the differential diagnosis of the submucosal tumor are obtained.
