Traumatic diaphragmatic rupture

Diagnosis of blunt traumatic ruptured diaphragm: is it still a difficult problem?

BACKGROUND

Blunt traumatic rupture of the diaphragm (BTRD) is uncommon. The diagnosis can be easily overlooked, and radiological findings misinterpreted. In a 15-year experience at the two major trauma hospitals in Brisbane reported in 1991, 85 patients with BTRD were treated, and the diagnosis not always made expeditiously. With the introduction of mandatory Early Management of Severe Trauma course training in the 90s and newer diagnostic tools, it might be expected that BTRD would be a less problematic diagnosis. The aim of this study was to review the incidence, diagnosis and outcome of BTRD at Auckland City Hospital over the last 10 years.

METHODS

Retrospective review of Auckland City hospital trauma registry between 1996 and 2005. Demographics include age, gender, injury severity score (ISS), length of stay, ICU admission days, methods of diagnosis and patient outcomes were reviewed.

RESULTS

Twenty-eight patients had TRD as result of blunt injury. Median ISS was 28.5. Most of the patients were diagnosed at the time of laparotomy for other associated injuries. Road traffic crash was the most common cause. Twenty-one out of 28 patients were discharged alive.

CONCLUSION

Diagnosis of BTRD remains difficult. It is rarely isolated. It requires a high index of suspicion. If suspected, chest X-ray (CXR) and other more advanced imaging modalities can be used as confirmatory tools.

Diaphragmatic rupture during labor

Diaphragmatic rupture during labor is uncommon and generally occurs in patients with a history of congenital diaphragmatic hernia or traumatic abdominal or chest injury. We present a case of a 41-year-old woman who presented with abdominal pain, vomiting and hypoventilation four days after a full-term home delivery. Chest radiography suggested the presence of a ruptured diaphragm, and laparotomy revealed a congenital left Bochdalek defect with herniation of the stomach, transverse colon and spleen into the left pleural cavity. Diaphragmatic hernia rupture during labor is a serious but rare complication that requires emergency surgery to prevent visceral perforation and cardio-respiratory failure.

Laparoscopic management of a late-diagnosed major diaphragmatic rupture

A 20-year-old male patient was admitted to our emergency ward because of acute respiratory insufficiency following gastroscopy 2 years after a car accident. The chest radiograph showed migration of the stomach into the left hemithorax. A large diaphragmatic hernia was diagnosed and repaired laparoscopically using slowly resorbable sutures and patches. Diaphragmatic rupture secondary to blunt thoracic or abdominal trauma is a rare injury, whose diagnosis may be delayed. The majority of these defects are diagnosed during laparotomy performed for other major abdominal lesions. If diaphragmatic rupture is suspected, and no lesion of a parenchymatous organ has been diagnosed, there is a role for diagnostic laparoscopy. In the absence of other abdominal injuries, diaphragmatic rupture can be repaired by minimal-access surgery.
