title: Gastric polyps and precancerous mucosal changes after partial gastrectomy.
abstract: Gastric polyps are considered to be rare. However, at endoscopy the prevalence of gastric polyps after partial gastrectomy was found to be 8.9% (30/336 patients) compared with 4.9% (20/407) in a clinical control material with a comparable age and sex distribution. Four patients with precancerous mucosal alterations were found in the operated group. Repeated endoscopic check-ups have at present been performed in 57.4% of these patients. In our experience the diagnostic accuracy with regard to malignancy is not entirely satisfactory. Histological examination of the surgical specimen from one of the 4 patients with precancerous changes showed a macroscopically invisible early carcinoma. Follow-up examinations (within 4 years) have in 5 out of 26 cases with sessile polyps disclosed carcinoma in 3 cases and precancerous changes or adenoma in another 2 cases. Careful re-examination of all patients with precancerous changes and gastric polyps is recommended.
