A case report: Perforation of the small intestine and sigmoid colon due to Kirschner wire migration

Introduction: Kirschner wires (K-wires) are extensively utilized in orthopedic and trauma procedures. Several risks associated with K-wires have been documented, including a rare case of intestinal perforation caused by wire migration into the pelvis. Case Report: In this report, we present the case of an 84-year-old woman with a history of left femoral neck fracture fixation surgery using a K-wire. She was hospitalized in the emergency room due to persistent dull pain in the left iliac fossa for 7 days. A contrast-enhanced computed tomography scan revealed an abscess in the left iliac fossa and a K-wire located in the abdominal cavity adjacent to the abscess. An emergency laparotomy was performed, and three perforations were identified. The surgery involved removal of the K-wire, closure of the small bowel perforation, and exteriorizing a segment of the damaged sigmoid colon to form a stoma. With timely diagnosis and treatment, the patient experienced significant recovery within 13 days postoperatively. Conclusion: Perforation of the small intestine and sigmoid colon due to Kirschner wire migration is a rare complication. However, it should be considered in patients with a history of orthopedic surgery involving K-wires.
