Perforation of the sigmoid colon with formation of a sigmoido-ureteral fistula caused by an ingested denture: a case report.

Accidentally ingested objects such as dentures can have serious health consequences with damage to the gastrointestinal tract. We report the case of a patient who ingested her dental plate unnoticed, leading to a sigmoid perforation and formation of a sigmoido-ureteral fistula. The patient presented to our emergency department with symptoms 3 months after ingestion. After unsuccessful endoscopic retrieval, a low anterior rectal resection with retrieval of the swallowed denture and resection of the left ureter with subsequent reconstruction surgery was performed.
