Multiple magnets ingestion, Gastro-colic fistula, Peritonitis"/>
The ingestion of a foreign body is common in children. But in adults, especially in those who have a mental illness, dysphagia, and consciousness disorders often occur. If a patient ingests more than two magnets, he can develop numerous complications such as bowel necrosis, perforation, and fistula formation. Here we report a case of a 32-year-old patient with gastro-colic fistula and peritonitis following ingestion of multiple magnets. In accidental ingestion of multiple magnets, early exploration should be considered. (Korean J Gastrointest Endosc 2010;41:168-171)
