Keep the change, doc!: coins in the upper GI tract of children.

Many children are brought to the Emergency Room each year because they have swallowed foreign bodies (FBs), particularly coins. Whether to remove these foreign bodies or let them pass through naturally is a constant dilemma for ER physicians. This article reviews our experiences in treating pediatric patients who underwent FB retrieval for coins, food particles and toy parts, and discusses their clinical and endoscopic findings. The vast majority (82%) of the swallowed FBs were lodged in the esophagus. A review of the literature and a suggested medical protocol to manage patients who have swallowed coins are also discussed in this article.
