ABSTRACT
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 female, who refers Case report: 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 ingested FB Discussion and conclusions: 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. In the case of perforation due to foreign body, different techniques can be performed; the most common are: In the stomach, primary suture, in the small bowel, primary suture or segmental resection with anastomosis, and in the colon, sigmoid and rectum, primary suture, wound eversion by colostomy, segmental resection with anastomosis, and segmental resection with proximal colostomy
