RESUMEN
Isolated colon injuries following blunt abdominal trauma have been reported at a rate of 0.1%-0.5%, with isolated sigmoid colon injuries involved in only 34.8% of single colon injuries. Surgical treatment options include recto-colonic anastomosis, resection with or without recto-colonic anastomosis, and colostomy. We report the case of a 39-year-old male patient diagnosed with isolated sigmoid colon rupture after a traffic accident, identified using contrast-enhanced abdominal computed tomography. The patient underwent emergency surgery, during which the Hartmann procedure was performed. This included excision of the sigmoid colon at both ends of the hiatus, creation of a proximal colostomy, closure of the distal end, and repair of the sigmoid disruption segment. Seven days after surgery, the patient's clinical symptoms were stable, and he was discharged.
