  • Look Inside

 Of the depressed lesions originating in the greater curvature of the gastric body, the detected number of benign ulcer and early carcinoma is so small that over-all estimation of them may not be possible.

 The deductive conclusion are mostly based on the cases we have encountered, ranging over the literature being an aid of the study.

 (1) It is not infrequent that benign ulcer of the greater curvature may be erroneously diaggnosed as malignant one, because it often shows “niche encastrée” in roentgen sign. The roentgen criteria differentiating between benign and malignant nature may depend upon whether a niche and its surrounding area are smooth or irregular.

 Both double contrast radiograph and compression picture are in this respect very important for further discrimination; these two methods should be fully emplayed to establish the nature of any lesion found in the greater curvature side of the gastric corpus.

 (2) In the greater curvature side, even a minute lesion such as ulcer scar or early carcinoma (Type Ⅱc) may show depressed appearance of the margin, “aspect encastree”, and this finding may depend on a certain change of a patient's position and degree of the barium-filled stomach, because the roentgen site of the greater curvature may not always correspond with its anatomical site.

 In general, barium-filled film and double contrast radiograph can demonstrate this kind of abnormality more effectively than mucosal study.

 (3) Mucosal folds are formed more markedly in the greater curvature side in other parts of the stomach. Consequently, the gross finding or abnormality may be better demonstrated, when examination by the prone and supine double contrast method or compression study is performed in an over-distended state of the stomach with contrast media and air.
