Abstract

The most significant feature of early carcinoma, be defined as the gastric carcinoma confined in mucousa and submucosa regardless of its size and shape, is its excellent prognosis; 5 year survival rate after operation inearly stomach carcinoma amounts to 93% in comparison with around 25% in advanced carcinoma, and so the detction ofthis early stomach carcinoma is most important subject to minimize the mortality from stomach carcinoma at the present time. For the diagnosis of early stomach carcinoma the radiographic study, cytology and gastroscopic examination are practisized, and of these the radiographic study has been revealed commonly best results, but byusual method of upper G-I study it is often difficult to diagnose accurately. Therefore, we have been employed thebaium and air double contrast method by insertion of the gastric tube. This method is simple and by this method,the adaquate amount of air may introduced into the stomach for the best visualization of the mucosal pattern andgastric juice may also aspirated in a case of which the stomach wall could not be coated by barium because of excessive gastric juice. Summary of the results of this studies of early carcinoma detection at the department of radiology, Severance Hospital during 6 months since May 1969 are as followings; of 1407 cases taken upper G-Istudy with double contrast method, 17 cases were diagnosed as possible early stomach carcinoma radiographically,and then only 6 cases had surgical resection of stomach. Of these 2 cases were confirmed pathologically and one was considered as precancerots lesion.
