The Authors report their experience with gastric polyps based upon 3,384 endoscopies performed from October 1992 to August 1995. The incidence of cystic polyps with respect to the examinations performed and to the number of gastric polyps found was 0.45% and 21.3% respectively. The cases were taken into account with respect to sex, age, number of lesions, location, size and association to Gardner's syndrome. A comparison between the observed cases and a comprehensive review of the relevant Literature was performed.
