This is done be debriding nonviable tissue and closing the rupture. Most of the time, the injury is repaired during laparotomy. Early surgery is important, as diaphragmatic atrophy and adhesions occur over time. Sutures are used in the repair. Other injuries, such as hemothorax, may present a more immediate threat and may need to be treated first if they accompany diaphragmatic rupture. Video-assisted thoracoscopy may be used. Prognosis
In most cases, isolated diaphragmatic rupture is associated with good outcome if it is surgically repaired. The death rate (mortality) for diaphragmatic rupture after blunt and penetrating trauma is estimated to be 15–40% and 10–30% respectively, but other injuries play a large role in determining outcome. Herniation of abdominal organs is present in 3–4% of people with abdominal trauma who present to a trauma center. Epidemiology
Diaphragmatic injuries are present in 1–7% of people with significant blunt trauma and an average of 3% of abdominal injuries. A high body mass index may be associated with a higher risk of diaphragmatic rupture in people involved in vehicle accidents. Over 90% occur due to trauma from vehicle accidents. Due to the great force needed to rupture the diaphragm, it is rare for the diaphragm alone to be injured, especially in blunt trauma; other injuries are associated in as many as 80–100% of cases. In fact, if the diaphragm is injured, it is an indication that more severe injuries to organs may have occurred. Thus, the mortality after a diagnosis of diaphragmatic rupture is 17%, with most deaths due to lung complications.
Diaphragmatic rupture (also called diaphragmatic injury or tear) is a tear of the diaphragm, the muscle across the bottom of the ribcage that plays a crucial role in breathing. Most commonly, acquired diaphragmatic tears result from physical trauma. Diaphragmatic rupture can result from blunt or penetrating trauma and occurs in about 0.5% of all people with trauma.Diagnostic techniques include X-ray, computed tomography, and surgical techniques such as an explorative surgery. Diagnosis is often difficult because signs may not show up on X-ray, or signs that do show up appear similar to other conditions. Signs and symptoms include chest and abdominal pain, difficulty breathing, and decreased lung sounds. When a tear is discovered, surgery is needed to repair it. Injuries to the diaphragm are usually accompanied by other injuries, and they indicate that more severe injury may have occurred. The outcome often depends more on associated injuries than on the diaphragmatic injury itself. Since the pressure is higher in the abdominal cavity than the chest cavity, rupture of the diaphragm is almost always associated with herniation of abdominal organs into the chest cavity, which is called a diaphragmatic hernia. This herniation can interfere with breathing. Signs and symptoms
Symptoms may include pain, orthopnea, (shortness of breath when lying flat), and coughing. In people with herniation of abdominal organs, signs of intestinal blockage or sepsis in the abdomen may be present. Bowel sounds may be heard in the chest, and shoulder or epigastric pain may be present.
