Traumatic diaphragmatic hernia presenting as a tension fecopneumothorax

Abstract

A traumatic diaphragmatic hernia is a well-known complication following blunt abdominal or penetrating thoracic trauma. Although the majority of cases are diagnosed immediately, some patients may present later with a diaphragmatic hernia. It occurs in approximately 3% of abdominal traumas. Diagnosis requires a high index of suspicion since diaphragmatic injury can only reliably be ruled out by direct visualization, i.e., laparoscopy. Hence, delayed presentation with complications secondary to the injury is not uncommon. We discuss a case of a young man who presented in respiratory distress 5 years after a stab wound to the left chest. The patient was hypoxic, with a chest X-ray (CXR) demonstrating a pneumothorax with effusion. A chest tube was placed with a rush of air and feculent drainage. CT scan revealed an incarcerated transverse colon in a diaphragmatic hernia. The laparotomy demonstrated necrotic colon in the chest with gross fecal contamination in the chest. The diaphragmatic defect was closed and a Hartmann's procedure performed. The patient developed empyema in the postoperative period. Our patient is the twelfth reported case of a tension fecopneumothorax resulting from traumatic diaphragmatic herniation. This paper reviews all cases, including the diagnostic workup, operative approach, and expected postoperative course of this unusual condition.
