Approach to the endoscopic resection of duodenal lesions

Figure 7 A patient presented for endoscopy because of gastrointestinal bleeding. A solitary Peutz-Jeghers hamartomatous polyp was seen in the duodenum on white light (A) and narrow-band imaging (B); This large polyp was removed endoscopically by first using an endoloop to constrict the broad stalk of the polyp (C); followed by hot-snare resection (D).
