RESUMO
The aim of this study was to evaluate the clinical conditions of gastric diverticulum. Fifty-four patients with gastric diverticulum (20 men and 34 women among 34,314 patients who underwent medical check-ups) were evaluated on indirect radiographs, for an incidence of 0.16% among the total number of examined cases, a rate lower than that of previous reports. Almost all cases were asymptomatic, had a single diverticulum, and showed a saccular shape. The age distribution indicated higher frequencies in the 5th and 6th decades, and the posterior wall of the fornix was the most common location. Size ranged from 0.6 cm to 12 cm, and 41 cases (75.9%) were between 1.0 cm and 4.0 cm in size. This entity should be kept in mind when reading radiographs of upper gastrointestinal series as well as recognition of pseudodiverticulum and aberrant pancreas as noted for the stomach in several past report. Diverticulum on the cardia, which was previously classified as gastric diverticulum, should be excluded because of the possibility of normal variation.
