Impacted esophageal foreign bodies in children.

Purpose: Foreign body (FB) ingestion in children has varied presentation. When unwitnessed, it poses therapeutic and diagnostic challenges especially in the presence of pre-existing anatomical pathology. We aim to analyze the clinical course, management, and outcome of children with impacted esophageal FBs.

Methods: Retrospective chart review (Jan 2000-Feb 2018) recruiting children with impacted esophageal FBs. FBs in cricopharynx and those that moved to stomach were excluded. Investigations/management were based on underlying anatomical pathology, duration of impaction, and difficult FBs. Clinical details, management, and outcomes were collated.

Results: Of 86 children, N1 = 31 had identifiable predisposing anatomic pathology and N2 = 55 had impactions in normal esophagus or difficult FBs. N1 group presented early (42 months), had recurrent impactions (1-6), and needed multiple dilatations (0-8) and longer follow-up (avg 35 months). Food matter was commonest impaction. Many had persistent symptoms. N2 group had commonly coin impactions and strictures developed in long standing or corrosive FBs. Most were asymptomatic.

Conclusion: Abnormal esophageal anatomy predisposes to impaction with organic food bolus. Age of presentation is earlier with recurrent impactions requiring multiple dilatations/surgery and longer follow-up. Metallic FBs commonly impact in normal esophagus and are often innocuous. Atypical/multiple FBs may mirror an underlying psychiatric illness.
