Investigations (Algorithm 5.1)
- Videofluoroscopy
- Microlaryngoscopy if upper airway problems suspected
- Barium radiology: for stricture, compression, H-type tracheo-oesophageal fistula or achalasia
- Oesophageal manometry
- Flexible gastro-oesophagoscopy, with biopsies (multiple oesophageal levels)
Algorithm 5.1 Assessment and management of swallowing difficulties
Management
Ingested foreign bodies
- Batteries lodged in the oesophagus cause caustic burn and perforation within hours, especially with nickel/cadmium, and should be urgently removed by endoscopy. Batteries that remain in the stomach require retrieval
- Most other objects, even if sharp, pass harmlessly through the gut. Removal can cause oesophageal trauma
- Occasionally, a foreign body becomes impacted at the ligament of Trietz or the ileo-caecal valve and causes obstruction
- Very rarely, an impacted foreign body lodged in the oesophagus erodes into other mediastinal structures. If suspected, surgical referral is required
