Swallowed foreign body

Last edited: 4/15/2026

Overview

Swallowed foreign bodies encompass a range of objects ingested unintentionally, posing risks from mechanical injury to obstruction and complications depending on location and nature of the object 1.

Diagnosis

  • Clinical history crucial for identifying potential foreign body ingestion 1.
  • Imaging (e.g., X-ray) often necessary to confirm presence and location of foreign bodies 1.
  • Endoscopy may be required for visualization and removal in cases of esophageal or gastric foreign bodies 1.

    • Management

  • First-line: Observation for asymptomatic, small, non-sharp objects that have passed the esophagus 1.
  • Adjunctive: Endoscopic removal for objects lodged in the upper gastrointestinal tract 1.
  • Special techniques: Household magnets can be effectively used for removing nasal magnets, minimizing trauma 1.

    • Special Populations

  • Pediatrics: Increased risk of aspiration and complications; endoscopic removal often preferred 1.
  • Elderly: Higher incidence of complications; careful assessment and management required 1.
  • Comorbidities: Presence of underlying conditions may necessitate tailored approaches; close monitoring advised 1.

    • Key Recommendations

  • Utilize household magnets for the safe removal of nasal magnets lodged in the nares, minimizing trauma 1 (Evidence: Expert opinion).
  • Employ imaging (X-ray) to confirm the presence and location of swallowed foreign bodies 1 (Evidence: Moderate).
  • Consider endoscopic intervention for removal of foreign bodies in the upper gastrointestinal tract 1 (Evidence: Moderate).
