Traumatic diaphragmatic hernia is a little frequent problem for the general surgeon, needing a high level of suspicion for the diagnosis, especially in patients carrying a closed trauma. We present the case of a male, 40-years-old patient, with a traumatic diaphragmatic hernia formed by stomach and greater omentum, secondary to a thoraco-abdominal trauma in automobile accident. A left video thoracoscopy allows arriving to the correct diagnosis. We expose the clinical data of the patient, his management, the surgical treatment applied and his subsequent evolution.
