Endoscopic Removal of a Denture Lining Material Stuck in the Duodenum.

A 52-year-old woman visited our hospital with a complaint of upper abdominal pain. Abdominal computed tomography did not show any lesion responsible for the pain. However, esophagogastroduodenoscopy identified a pale, pink-colored, U-shaped foreign body stuck in the descending part of the duodenum. We removed it by gently pulling forward in an antegrade fashion with the use of a snare. Duodenography after the removal did not show any sign of leakage to the abdominal cavity or to the retroperitoneum. The foreign body was found to be a denture lining material equipped 3 days previously.
