Gastric submucosal tumor diagnosed using gastric radiography

Abstract

Objective This study aimed to reveal the details of lesions diagnosed as gastric submucosal tumors using gastric radiography.

Subjects and Methods We studied 92 lesions diagnosed as gastric submucosal tumors out of 23,894 using optional gastric radiography at our hospital between April 2015 and August 2023. We retrospectively studied the tumor diameter by lesion site, imaging methods (double-contrast or thin-layer method), and final diagnosis.

Results The number of tumors in the U, M, and L regions was 53, 21, and 18, respectively. The overall mean tumor diameter was 15.6 ± 12.4 mm, showing no significant difference among lesion sites in the U, M, and L regions. The double-contrast method was more commonly used to visualize tumors in the U and L regions, whereas the thin-layer method was more commonly used to visualize tumors in the M region. Of the 53 lesions closely examined using endoscopy, 25 were actually submucosal tumors. In addition to submucosal tumors, one adenoma lesion and one early-stage cancer lesion were identified.

Conclusion The thin-layer method was useful for visualizing gastric submucosal tumors in the M region using gastric radiography. A wide range of tumors, including epithelial tumors, were identified.
