Abstract
Recent studies have shown an increase in morbidity associated with button battery ingestions in children. To perform a comprehensive, imaging-focused review of all patients with confirmed button battery ingestions/insertions imaged at our institution in the last 15 years. Radiology reports from Jan. 1, 2000, to July 12, 2015, were searched for the terms “battery” and “batteries.” Confirmed cases of battery ingestion/insertion for which images were available were reviewed. Cases were reviewed for imaging studies performed, imaging findings, patient demographics, clinical history and management. Two pediatric gastroenterologists reviewed endoscopic images and graded mucosal injuries in selected cases. Two hundred seventy-six cases were reviewed. All patients were imaged with radiography, 19 with fluoroscopy (6.8%), and 4 with CT (1.4%). Batteries retained in the esophagus (n = 27, 9.8%) were larger in diameter on average than those that had passed distally (22.1 ± 3.3 mm vs. 13.7 ± 1.6 mm, PPPP20mm in diameter warrant increased clinical scrutiny due to higher likelihood and severity of injury. Implementation of recent pediatric gastroenterology societal guidelines will likely lead to a substantial increase in the number of CT and MRI examinations.
