So piecemeal plypectomy was performed using a vinyl snare for the prevention against the hemorrhageo Two thirdsof the polyp was removed by the procedure. There was noaccldeht such as a hemorrhage and a perforation. Histology was a Brunner's gland adenoma(Figure 4-a, 4 -b), The sizeof the remaining tumor was diminished a week lateroIt is suggested that the piecemeal Polypectomy using the vinyl snare will be safe and effective in patients with a giant duodellal polyp more than 3cm in diameter.
