Swallowed nail perforating the anterior surface of the stomach and penetrating the abdominal wall from the insideCase report

Abstract Foreign body ingestion is a problem generally found in children, some psychological diseases, and people with mental retardation. In most cases, they pass through the gastrointestinal tract, come out with faeces and rarely cause infection, local reaction, migration, or perforation. A CT scan is the ideal choice for complicated cases diagnosis. We report a case of a pointed rusty nail, perforating the stomach from inside, passing through the skin of the abdomen, outward from the left upper quadrant, and successfully extracted by open surgery in a patient with mental retardation. We recommend that we can care for those with mental retardation or who have foreign body ingestion habits by checking them regularly.
