Transabdominal Minimally Invasive Repair of a Left Chronic Traumatic Diaphragmatic Hernia.

Although the exact incidence of traumatic diaphragmatic hernia (TDH) is unknown, it can carry significant morbidity if not treated promptly. TDH is thought to be more common in penetrating thoracoabdominal trauma compared to blunt trauma. The left side is thought to be more commonly affected than the right due to the protective effects of the liver on the right hemidiaphragm in trauma. Although large defects are evident on CT imaging and the detection rate is improved with higher resolution CT scanners, smaller ruptures may require laparoscopy for definitive diagnosis if there is a high index of suspicion. In this case report, we present a case of a missed left TDH on CT imaging, with eventual herniation of the omentum and stomach. Although TDH traditionally is approached via thoracotomy or laparotomy, we demonstrate that a transabdominal minimally invasive approach with robot-assisted laparoscopic repair is a viable option, with the potential to reduce the morbidities associated with the open approach.
