[Double-contrast gastrography and gastroscopy in the diagnosis of gastric polyps. Personal experience]

Gastric polyps are benign tumors which have been less uncommonly detected in recent years, due to the refinement of both radiologic and endoscopic investigations. From 1981 through 1985 gastric polyps were detected in 102 patients (1.9%) out of 5368 radiologic examinations. In the same period, 98 cases (3.3%) were detected out of 2942 endoscopic examinations. The comparison of data in these two series shows a superimposition. Despite an increased percentage of endoscopic findings (to some extent due to previous radiologic reports), the authors assert the diagnostic efficacy of double contrast radiologic investigation as a first approach to benign polypous lesions of the stomach. As far as histology is concerned, a clear prevalence is shown of hyperplastic versus adenomatous polyps (90 and 8 cases respectively).
