# Clinical experiences of 109 children with foreign body ingestion: a retrospective study from Kunming, China

## TL;DR

This study examines 109 children in China who swallowed foreign objects, focusing on the types, locations, and complications of these ingestions.

## Contribution

The study provides insights into the prevalence and complications of metallic foreign body ingestion in children from Kunming, China.

## Key findings

- Metallic objects, especially coins, were the most commonly ingested foreign bodies.
- The upper esophagus and stomach were the most frequent sites of foreign body impaction.
- Complications like mucosal erosion and congestion were observed in some cases.

## Abstract

This study was designed to assess the types and locations of foreign bodies ingested by pediatric patients, investigate the complications associated with these ingestions, and explore the demographic factors influencing the incidence of specific foreign body types and outcomes.

A retrospective analysis was conducted on 109 pediatric patients who presented with foreign body ingestion due to foreign body ingestion (FBI). Data were collected on patient demographics (age, sex, body weight, and living environment), types of ingested materials (metal, plastic, magnetic), and anatomical locations of foreign bodies (esophagus, stomach, duodenum). The occurrence of complications, such as mucosal erosion, congestion, and edema, was also recorded. Descriptive statistics was used to analyze relationships between variables.

The majority of ingested foreign bodies were metallic, with coins being the most common object, followed by batteries and other metals. Plastic materials and magnetic beads were also noted. The most frequent locations for foreign body impaction were upper esophagus and stomach. Complications such as mucosal erosion and congestion were observed.

This study highlights the prevalence of metallic foreign bodies, particularly coins, in pediatric FBI cases. The upper esophagus and stomach were the most common locations for impaction.
