Endoscopic Retrieval vs Observation in Cylindrical Battery Ingestion.

Battery ingestion, particularly in the pediatric population, has become more common since the development of button batteries. Consequently, formal recommendations regarding the management of this battery type have been developed. Larger cylindrical battery ingestion is less common, with fewer cases reported. As such, no clear practice guidelines have been developed for the management of cylindrical battery ingestion. We present a case of an incarcerated adult who ingested 2 AA batteries. One battery was retrieved endoscopically, but the second passed into the distal small bowel beyond endoscopic means of retrieval. The second battery passed spontaneously via the rectum after administration of laxatives and supportive care. Our case and review of the literature demonstrate that nonsurgical, conservative management with close clinical monitoring is possible in a hospital setting after cylindrical battery ingestion. Cases with concerning clinical symptoms or a history of damage to the battery casing warrant endoscopic or surgical intervention.
