[Stomach diverticula. Endoscopic contribution].

Four cases of gastric diverticula culled from a series of about 3600 oesophagogastroduodenoscopies performed at the digestive endoscopy service of the Valduce Hospital, Como, between 1977 and 1980 are discussed. In the first case, the diverticulum involved the fundus; in the second, a small diverticulum of the greater curvature was combined with postpyloric substenosis that could not be passed by the instrument; in the third, a diverticulum of the fundus was accompanied by a 0.5 cm diameter polyp on the greater curvature; in the fourth, a diverticulum of the fundus was accompanied by a small diverticulum near the duodenal ampulla. Stress is laid on the usefulness of endoscopy in both diagnosis and treatment, as a means of distinguishing cases open to medical management from those that can be more profitably treated surgically.
