Foreign body ingestion is common, usually resolving without issue. Endoscopic removal is needed in 10-20% of cases, with surgery rarely required (<1%).
Area of Science:
- Gastroenterology
- Medical Devices
- Emergency Medicine
Background:
- Foreign body ingestion is a frequent occurrence with potential for serious complications.
- Most ingested foreign bodies pass through the gastrointestinal tract spontaneously.
- A small percentage necessitates medical intervention, including endoscopy or surgery.
Purpose of the Study:
- To outline the clinical presentation of foreign body ingestion.
- To detail potential complications associated with ingested foreign bodies.
- To provide guidance on the timing and techniques for endoscopic foreign body retrieval.
Main Methods:
- Review of clinical cases and data on foreign body ingestion.
- Analysis of European Society of Gastrointestinal Endoscopy (ESGE) recommendations.
- Description of endoscopic procedures for foreign body removal.
Main Results:
- Foreign body ingestion is common, with most cases resolving without complications.
- Endoscopic removal is required in 10-20% of ingested foreign body cases.
- Surgical intervention is necessary in less than 1% of cases.
Conclusions:
- Foreign body ingestion management requires careful clinical assessment.
- Endoscopic retrieval is the primary intervention for complicated cases.
- Adherence to established guidelines ensures optimal patient outcomes.
