The fate of swallowed button batteries in children.

The method of treatment and fate of 41 button batteries ingested by 34 children were analysed; 31 batteries were in the stomach and 10 beyond the pylorus. In 31 batteries situated in the stomach, removal by magnet tube technique was attempted in 30 batteries, 25 being successfully taken out, while 5 failed passing through the pylorus at the duodenum. One was removed endoscopically, since a magnet tube was not available. The remaining 10 batteries in 10 children were found at different levels from the duodenum to the rectum. In addition, 5 batteries were pushed down from the stomach during magnet tube removal. These 15 batteries, located in the intestine were excreted during 35 hours. In contrast to other asymptomatic foreign bodies that are allowed to pass through the GI tract spontaneously, we feel that button batteries should be removed by magnet tube technique to avoid complications such as GI tract perforation with associated bleeding, possible mercury poisoning and burns. Magnet tube removal is a simple and safety method requiring neither anaesthesia nor admission.
