Multiple Early Gastric Carcinoma in Cases Treated Endoscopically

Abstract

Abstract:Multiple gastric carcinoma was endoscopically diagnosed in 14 patients (13.6%) with 33 lesions (27.3%), out of 103 cases of early gastric carcinoma treated by endoscopic surgery. The sex ratio of these patients was 11 males to 3 females, and their mean age was 61.7 years old. In 79% of the patients the macroscopic type of the lesions was the same. Twelve of 33 lesions were metachronous lesions diagnosed by endoscopy using the dye contrast method. All of the metachronous lesions were evaluated as invading only as far as the mucosa. Almost all of the metachronous lesions were located at a height similar to that of the initial lesion or in a more oral direction. Eleven of 12 metachronous lesions were less than 2 cm in diameter, including 5 minute cancer lesions which were less than 5 mm in size. All these lesions were treated again endoscopically without gastrectomy. These results suggest that an annual endoscopy using the dye contrast method permits early detection of gastric carcinoma at a stage at which it can be treated endoscopically.
