Pedunculated Duodenal Lipoma Treated with Endoscopic Polypectomy with a Detachable Snare
2008
We report endoscopic
polypectomywith a detachable snare in a patient with a hemorrhagic pedunculated duodenal
lipoma. A 67-year-old man with a history of
spinal canal stenosiswas admitted to our hospital because of recurrent tarry stools and anemia. Esophagogastro-
duodenoscopyrevealed a pedunculated submucosal tumor measuring approximately 4 cm, in the second part of the
duodenum. The tumor had a slightly yellowish coloration, and longitudinal erosion was noted on the surface of the tumor. There were no significant findings in the esophagus, stomach and bulbs. Barium study revealed a pedunculated submucosal tumor measuring 40 × 12 mm in the second portion of the
duodenum. We judged that the submucosal tumor may have been the hemorrhagic source, and removed it by endoscopic snare
polypectomywith a detachable snare. No complications occurred during endoscopic procedures. Histopathological examination revealed that the tumor was composed of mature adipose tissue in the
submucosa, which was consistent with a diagnosis of
lipoma. In our experience, endoscopic
polypectomywith a detachable snare is useful for the treatment of hemorrhagic pedunculated duodenal
lipoma.
