Abstract
As the preliminary study of laser photocoagulation of hemorrhagic gastric ulcer, the size of exposed blood vessel in the ulcer was examined. The subjects were 78 lesions seen in 71 patients. The mean diameter of exposed blood vessel was 0.92mm. The vessels coresponding to 70.5 % in the lesions were smaller than 1mm and 94.9 % of them were smaller than 2mm. This means that the ruptured blood vessel seen in the ulcer will become the object of photocoagulation by Nd-YAG. Furthermore, by the studies of those ulcers, they mainly located on the lesser curvature of lower body and angulus, where it was difficult to find out by the forward viewing endoscope.
