Endoscopic removal applies to sessile or pediculated gastroduodenal tumours of benign aspect, whose size is inferior to 2 cm. It is a fairly safe technique: accidents in 4.60/o cases and no death in these cases concerning 150 snare polypectomies. Endoscopic removal allows an accurate histological diagnosis and makes it possible to adopt a reasoned behaviour. An endoscopic control is necessary one month after the removal, and in case of adenomatous polyp an endoscopic examination is advisable every two years.
