With the same intention and in the same method as that in part 1, I studied 81 concaving lesions in 71 cases which were detected by mass examination survey and were operated. The results were as follows: 1) As to the concaving type, irregularity and rigidity of the stomach wall, shortened lesser curvature and abnormal relief view were the important findings to detect the lesion. 2) 2.3 findings were found in every lesion. 3) A finding was detected in 1.9 sheet of films out of 5. The irregularity of the wall, rigidity of the wall, unusual indentation of stomach wall, irregular filling defect and deformity of the antrum were detected in more than 2 sheet of films but widened stomach angle and abnormal relief view were detected only a sheet of film. 4) The barium filled stomach in upright position was important and effective to detect the lesion. On the contrary, prone and upright left oblique position was uneffective. Many of the irregularity and rigidity of the stomach wall, widened stomach angle and shortened lesser curvature were detected by upright position. Abnormal relief view was detected by supine position. 5) A few lesions within 2 cm in diameter could not be detected. The bigger the lesions were, the more frequently the rigidity of the stomach wall and the abnormal relief were found. 6) In the lesion around the angle, widened stomach angle and filling defect were frequently found. In the lesions around the corpus, nische and fleck were more frequently found.
