Objective: The aims of this study were to characterize the patient population and initial presentation and care of esophageal button battery ingestion and provide descriptive data including factors affecting accurate diagnosis, duration of battery exposure, and battery removal.
Methods: This was a retrospective cohort study from 2007 to 2020 at a single-center, large-volume, urban academic pediatric hospital system. Included participants were children 6 months to 18 years old who underwent removal of an esophageal button battery impaction at our institution.
Results: Our cohort comprised 63 patients; ages ranged from 7 to 87 months with a median of 27 months. Median button battery size was 2.12 cm with 59% lodged in the proximal esophagus. A prolonged impaction, greater than 12 hours, occurred in 46% of patients. Risk ratio analysis demonstrated that lack of caregiver suspicion of ingestion was associated with prolonged impaction (risk ratio, 3.39; confidence interval, 2.15-5.34). Misdiagnosis of button battery ingestion occurred in 10% of cases. The majority of patients, 87%, required transfer from a referring facility with a median total distance of 37 miles (range, 1.4-160 miles) from home to facility where battery was removed.
Conclusion and relevance: This study describes the initial presentation and care of a large cohort of pediatric esophageal button battery ingestion. It emphasizes the continued need for primary prevention, prompt identification, and removal of these batteries. There are many challenges in caring for these patients involving multiple pediatric disciplines, and guidelines encompassing a multidisciplinary approach would be beneficial.
