Epidemiology and management of oesophageal coin impaction in children.
OBJECTIVE
The epidemiology of oesophageal coin impaction in children is poorly understood. We aimed to assess characteristics of patients with coin impaction and identify predictors of type of coin impacted and management strategies.


METHODS
Cases of coin impaction from 2002 to 2009 were identified by querying a tertiary care centre's billing, clinical, and endoscopy databases for the International Classification of Diseases, 9th Revision code "935.1 - foreign body in the oesophagus." Charts were reviewed to confirm case status and to extract pertinent data.


RESULTS
Of 113 patients with oesophageal coin impaction (55% male; 45% Caucasian; mean age 2.9 years), 65 (58%) swallowed a penny, 85 (80%) had the impaction in the proximal oesophagus, and 103 (91%) required a procedure. Thirty-five (34%) patients had an upper endoscopy performed by a gastroenterologist and 68 (66%) had a laryngoscopy or oesophagoscopy performed by an otolaryngologist. Only 2 minor complications were noted. There was no significant relationship between the coin type and location of impaction, but 99% of cases performed by otolaryngologists were for proximally impacted coins, compared to 49% for gastroenterologists (p<0.001).


CONCLUSIONS
Oesophageal coin impaction disproportionately affected young children and extraction was frequently required. Whilst pennies were the most commonly impacted coin, there were no clear predictors on impaction based on coin type.
