Gastric polypoid lesions. Our experience

The Authors report the results of their experience on polypoids lesions of the stomach and on endoscopic polypectomies. A study on 2000 OGD (oesophagogastroduodenoscopy) has been carried out on 95 patients with polypoid lesions. The authors have analysed the associations existing between histological type and symptomatology and localisation of the lesion and the status of the Helicobacter pylori and the risk of cancerization. The data were confronted with the ones already available. In the majority of the cases, the polypoid lesions were asymptomatic, the localization changed according to the histological type, with the antrum as the most affected area. The presence of Helicobacter pylori does not seem to be correlated to the lesion, except in the case of hyperplastic polyps. The percentage of risks of cancerization increased in case of adenomatous polyps. In one patient signet ring cell carcinoma within a gastric polyp was found. Gastric signet ring cell carcinomas are peculiar for their rarity as well as for the growth in polypoid lesions. We confirm the higher frequency of hyperplastic polyps and the correlation between histological type and localization. Endoscopic polipectomy is the first approach in gastric polyps, with lower risk of developing cancer. Only in selected cases, as in one in ours, it is advisable the surgery.
