Insights
A watch and wait approach is safe for asymptomatic children with oesophageal coins. Most coins pass spontaneously within 18 hours, avoiding complications and the need for general anesthesia (GA).
Area of Science:
- Pediatric Emergency Medicine
- Radiology
- Gastroenterology
Background:
- Esophageal foreign body ingestion is common in children.
- Radiographic confirmation of an esophageal coin necessitates a management decision.
Purpose of the Study:
- To evaluate the safety and efficacy of a 'watch and wait' approach for asymptomatic children with esophageal coins.
Main Methods:
- Retrospective case note review of children under 16 years.
- Analysis of data over a 7-year period (2004-2010).
- Inclusion criteria: confirmed esophageal coin on X-ray.
Main Results:
- 89% of asymptomatic children managed conservatively had spontaneous coin passage within 18 hours.
- No complications were observed in conservatively managed children.
- No patient with a middle or lower esophageal coin required general anesthesia (GA).
Conclusions:
- A period of observation up to 18 hours is safe for asymptomatic children with esophageal coins in the UK.
- Conservative management can be safely performed at home with follow-up X-ray.
- This approach avoids unnecessary interventions like GA.
Objective:
Is a watch and wait approach safe in asymptomatic patients presenting to the emergency department with a confirmed oesophageal coin on x-ray?
Methods:
A retrospective case note review for children <16 years attending with a confirmed oesophageal coin on x-ray over a 7-year period (1 January 2004 to 31 December 2010).
Results:
89% (33/37) of coins in asymptomatic patients, who were conservatively managed, had passed spontaneously on repeat chest x-ray up to 18 h later. No patient who was discharged with a middle or lower oesophageal coin required a GA and no child who was treated conservatively developed any complications.
Conclusion:
In the UK asymptomatic children, with no history of tracheal or oesophageal disease and a confirmed oesophageal coin on x-ray should undergo a period of observation up to 18 h. This can be safely undertaken at home, followed by a repeat x-ray in the emergency department.
