Description

Children are at an increased risk of button battery ingestion because of the increased prevalence of button batteries in toys, games and so on, especially the higher voltage large (20mm) lithium batteries. We examined the treatment outcomes and problems of the patients suffering from button battery ingestion in our hospital. Between January 1988 and October 2014, 124 patients largely composed of infants under 3 years of age were admitted to our hospital. The sites of the batteries at diagnosis were the esophagus in 8%, the stomach in 65%, and the intestine in 27%. Symptoms of battery impaction in the esophagus were vomiting, anorexia, or fever. If the batteries remained over 2 hours in the esophagus, endoscopic removal of batteries was needed under general anesthesia and there were 6 patients with ulcer formation. Batteries in the stomach were removed with a magnet tube if possible. If not, small batteries in the stomach were excreted spontaneously and large batteries in the stomach were removed with endoscopy. Laparotomic removal of a small battery was needed in a baby because of pyloric injury. In conclusion, button batteries in the esophagus should be removed as an emergency procedure to prevent ulcer formation. Emergency removal of batteries in the stomach is recommended in the cases of infants, or large batteries.
