Histologic types and surveillance of gastric polyps: a seven year clinico-pathological study

Hepatogastroenterology. Mar-Apr 1998;45(20):579-82.

Abstract

Background/aims: This is a seven-year prospective study based on all gastroscopic examinations of our patient population in order to study gastric polyps.

Methodology: One hundred and twenty-one polyps, removed from 96 patients were analysed. All polyps, after endoscopic polypectomy, were classified according to their histotype. The follow-up was carried out in 49 patients for a mean time of 40 months.

Results: Polypoid lesions were more frequent in females (57.3%) and they were preferentially located in antrum (60.3%). Hyperplastic and inflammatory polyps were 55.4% and 28.9%, respectively, while adenomatous lesions were 9.9%. Four fundic gland polyps, 1 carcinoid, 1 type I early gastric cancer and 1 pancreatic heterotopia were also found. During the follow-up no malignant lesion was encountered. On the other hand 25 benign polyps were found in 19 patients.

Conclusions: Our experience confirms that there is a close relationship between the size of the polyps and the neoplastic change. In fact, in our series all polyps were smaller than 2 cm and only one malignancy was found (an early gastric cancer). None of adenomatous polyps was associated with gastric adenocarcinoma. Our data also indicates that when a polypectomy is carried out for small polyps (smaller than 2 cm.) a strict follow-up is necessary for the neoplastic polyps only.
