To warn about the danger of children swallowing many magnetic magnets, we report a case of a 14-month-old child who swallowed 5 magnets causing perforation and had successful intestinal anastomosis surgery. The method used in the study is to report 1 case. The child was admitted to the hospital with symptoms of vomiting a lot, fatigue, not having a bowel movement for 2 days, and unknown history of swallowing a foreign object. Examination showed signs of dehydration, abdominal distention, and no peritoneal tenderness. Unprepared abdominal X-ray showed a radiopaque foreign body located in the right iliac fossa, with water and air levels. Diagnosis of intestinal obstruction due to foreign objects. When dissecting into the abdomen, many loops of small intestine were dilated, lots of exudate, 30 cm from the ileocecal corner, there was a foreign magnet about 2.5 cm long (due to 5 magnets sticking together) through 2 The intestinal loop causes the Ω-shaped fistula to twist and cause obstruction. Surgery to remove the section of intestine containing magnets and end-to-end anastomosis. Reports show that children swallowing many magnets can cause dangerous complications such as intestinal perforation. Therefore, when a child shows signs of intestinal obstruction/intestinal obstruction, suspected of swallowing a foreign object, surgery should be performed as soon as possible to avoid complications of intestinal perforation.
