FREQUENCY, LOCATION, AND AGE AND SEX DISTRIBUTION OF VARIOUS TYPES OFGASTRIC POLYP

Data on the frequency and location of the various types of gastric pol yps are highly inconsistent. In a retrospective analysis of 5515 gastr ic polyps obtained from 4852 patients in the period between 1969 and 1 989, including reexamination of 197 surgical, 1572 polypectomy, and 37 46 biopsy specimens, the most frequent types found were Elster's gland ular cysts (fundic gland polyps) (47.0 %), followed by hyperplasiogeno us polyp (28.3 %), tubular adenoma (9.0 %), adenocarcinoma (7.2 %), in flammatory fibroid polyp (3.1 %), carcinoid tumor (1.7 %), Brunner's g land heterotopia (1.2 %), and tubulopapillary adenoma (1.0 %). Peutz-J eghers polyps, juvenile polyps, and pancreatic heterotopia were found in younger patients (mean ages: 33.39 and 45 gears, respectively), whe reas the age of most patients (66 %) with glandular cysts was between 40 and 69 years. Patients with any of the other types of gastric polyp s were mostly (55-100 %) over 60 years of age at the time of diagnosis . Glandular cysts, hyperplasiogenous polyps, inflammatory fibroid poly ps, and carcinoid tumors were significantly more common in women, whil e all the other polyps were more or less equally distributed between t he sexes, Glandular cysts and carcinoid tumors were relatively small ( mean diameter 8 mm), and were mostly located in the corpus (100 % and 83 %, respectively). Medium-sized pancreatic heteropias, Brunner's gla nd heterotopias, and inflammatory fibroid polyps (mean sizes 7-10 mm) were usually located in the antrum (100 %, 81 %, 80 %, respectively), while the other polyps had an average size of between 10 and 16 mm and were distributed equally throughout the stomach.
