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

Aim: 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. Methods: 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. Results: 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. Conclusion: 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.
