Introduction: The ingestion of a foreign body (FB) is uncommon, yet important cause of gastrointestinal injury; it has more incidence in the pediatric population. Less than 1 % of the FB is associated with complications, particularly gastrointestinal perforations. We present the case of a 76 years old Case report: female, who refers lower quadrant abdominal pain of 48 hours of evolution, with gradually exacerbation over 1 day, The CT Findings reveal the presences of pneumoperitoneum and a high-density FB in the architecture of rectosigmoid colon, she underwent exploratory laparotomy with trans -surgical ndings: Perforation of 0.5 cm in rectosigmoid union, with the protrusion of a bone with perilesional edema. Treated with suturing in two planes, with good evolution. Most ingest Discussion and conclusions: ed FB pass through the GI tract uneventfully within 1 week, and is more common among children and older individuals. Patients with dentures, alcoholics and psychiatric patients are at high risk of FB ingestions.
