Elster's classification differentiates epithelial gastric polyps on the basis of cells origin and relative tendency to change into a malignancy. Out of 3.920 endoscopy of upper digestive tract during the last 10 years, we found 41 gastric polyps, 50% asymptomatic. Endoscopic polypectomy were performed in 61% of cases, without any complication. The other 39% were followed-up and/or surgically resected, according to the results of biopsy. Endoscopy is mandatory for detection of lesions often asymptomatic and histological study of surrounding gastric mucosa. Small polyps must be treated by radical endoscopic polypectomy. If they are too big for endoscopic polypectomy, it's well advised and safer to perform periodic biopsy for hyperplastic type and a surgical resection for adenomatous ones. The detection of intestinal metaplastic or malignant changes beyond basal membrane suggests a resection both subtotal or total according to topography of the lesions. In conclusion the role of endoscopy is well defined in order to clarify histological attributes of gastric epithelial polyps and surrounding mucosal areas. More restricted is its role in the treatment of these lesions.
