From 1969 to 1989, 1106 cases of early gastric carcinomas were treated in our hospital, and 9 cases (0.8%) of an early gastric carcinoma with a pyloric stenosis were found among them. Five of these cases involved males and 4 cases females. The average age of these patients was 57.1 years. An accurate preoperative diagnosis was very difficult and 7 cases had been considered to be advanced gastric carcinoma preoperatively. In all these cases the lesions were found located on the pyloric ring or in the antral region. Further, all cases evidenced a submucosal infiltration and/or ulceration in the lesion. Most of the stenotic cases had lesions greater than 3.1 cm in diameter, with diameters of over 1.1 cm in the ulceration and the submucosal infiltration. Some early gastric carcinomas in the antral region with no pyloric stenosis also had lesions that were over this size.
