Endoscopic Resection of a Pedunculated Brunner’s Gland Hamartoma of the Duodenum

Figure 2

Endoscopy images. Esophagogastroduodenoscopy results showed a pedunculated polyp measuring approximately 20 mm ((a), (b)). The polyp was easily extended to the stomach by traction with biopsy forceps (c). Magnifying observation with narrowband imaging revealed that the surface of the polyp was entirely covered with intact duodenal mucosa (d). Endoscopic ultrasonography showed multiple cystic structures ((e), (f), arrows).
