RESUMEN
Traumatic diaphragmatic rupture is not an uncommon problem, particularly in the last few years because of the increasing number of road accidents, improved diagnostic techniques and resuscitation techniques after serious traumas. In a certain number of cases, post-traumatic diaphragmatic hernias may become clinically manifest only months or years after thoracic or abdominal trauma and are still a challenge to surgeons because of the vague clinical symptoms and the diagnostic difficulties involved. The Authors report a case of acute colon occlusion due to diaphragmatic hernia 24 months after thoraco-abdominal trauma. None of the radiological or endoscopic examinations demonstrated the presence of diaphragmatic hernia. Laparoscopy showed a diaphragmatic rupture with incarceration of the left colonic segment. The laparoscopic procedure was converted for technical reasons and the diaphragmatic defect was closed with a primary suture.
