Button battery ingestion: A serious pitfall of diagnosis of ingested foreign bodies in children from resource-limited settings - A case report.

INTRODUCTION AND IMPORTANCE

Button battery ingestion and impaction in the oesophagus can result in severe morbidity and even fatality if not diagnosed and managed urgently. Delayed or missed diagnosis due to the sometimes-vague symptomatology and limited investigations in resource-limited settings further increases the complications rate.

CASE PRESENTATION

Case 1: A 2 years old male child presented with a nine months history of recurrent respiratory tract infections not responding well to medical treatment. A radio-opaque round foreign body (FB) was incidentally seen in the chest. Rigid esophagoscopy and removal were done, but the child had developed a trachea oesophagal fistula. The fistula was managed conservatively by retaining a nasogastric tube until spontaneous fistula closure happened. Case 2: A 2 years old female child presented with a one-year history of poor feeding, vomiting, difficulty in breathing and persistent wet cough, and fever. He underwent tonsillectomy with no improvement. A radio-opaque round FB was incidentally seen in the oesophagus near the carina by a chest x-ray. A thoracotomy had to be done after two failed removal attempts by rigid esophagoscopy.

CLINICAL DISCUSSION

The similarity in the symptomatology of common aerodigestive conditions with FB ingestion compounded with low chances of witnessing the ingestion creates a possible pitfall for clinicians when resulting in a missed or a delayed diagnosis, further raising the complications rate of FB impaction in the oesophagus, such as tracheoesophageal fistula formation or the need for a massive surgery such as thoracotomy to remove the button battery.

CONCLUSION

Complications of foreign body ingestion in the paediatric population can have serious complications. High morbidity and mortality may be attributed to delayed diagnosis and intervention.
