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

## TL;DR

A woman unknowingly swallowed a denture, which caused a severe intestinal injury and a fistula between the colon and ureter, requiring surgery.

## Contribution

This case highlights the rare but serious complications of ingested dentures and the need for prompt surgical intervention.

## Key findings

- Ingested denture caused sigmoid colon perforation and a sigmoido-ureteral fistula.
- Endoscopic retrieval failed, necessitating surgical resection and ureteral reconstruction.
- Delayed presentation (3 months) increased surgical complexity and risk.

## Abstract

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.
