Pedunculated duodenal lipoma treated with endoscopic polypectomy with a detachable snare.

We report endoscopic polypectomy with a detachable snare in a patient with a hemorrhagic pedunculated duodenal lipoma. A 67-year-old man with a history of spinal canal stenosis was admitted to our hospital because of recurrent tarry stools and anemia. Esophagogastroduodenoscopy revealed a pedunculated submucosal tumor measuring approximately 4 cm, in the second part of the duodenum.
