Recent trends in foreign body ingestion (FBI) epidemiology: A national cohort study.

Background and Aims: Foreign body ingestion (FBI) in children is a critical health concern. This study aimed to describe the epidemiology of FBI in children in Italy.
Methods: We retrospectively enrolled children <18 years admitted for FBI from January 2015 to December 2020. Data were collected across 21 hospitals with dedicated pediatric endoscopy services and normalized by the population of the corresponding municipalities.
Results: A total of 5,771 FBI cases were analyzed. FBI incidents showed consistent time trends across age groups, with most events occurring at home and being witnessed (94.7 %). Children <6 years accounted for 74.3 % of cases. Comorbidities were present in 5.3 % of cases, primarily neurologic/psychiatric disorders in older children (6-17 years). Blunt objects accounted for 65.5 % of ingestions. Young males commonly ingested button batteries, while females showed higher rates of ingesting hair products and jewelry. Most children were discharged (60 %) or observed briefly (75 % of total admissions), with endoscopic removal performed in 24 % of cases.
Conclusions: Rates of FBI have remained stable over the years, including during the COVID-19 pandemic. FBI predominantly occurs in domestic settings among healthy young children, particularly those ≤5 years old. These findings emphasize the need for preventive measures to reduce the impact of FBI among children.
