Avulsion injuries of domes of the diaphragm are rare injuries and may occur following lateral thoracoabdominal trauma. We share our experience of two cases of avulsion injuries of the right dome of the diaphragm. Our first case presented within a week following blunt trauma to the abdomen, and on thoracotomy, an effective repair was performed by restoring attachment of the diaphragm to the parietes. Our second case presented with severe respiratory distress, 1½ months after sustaining blunt injury chest and abdomen in a road traffic accident and on thoracotomy was found to have a completely necrosed right hemidiaphragm, and hence, no repair could be performed. However, the patient could not be weaned off ventilator and died after 3 months of primary injury. These cases highlight the importance of early diagnosis and repair of diaphragmatic injuries for a favorable outcome.

| Introduction|| |
Traumatic diaphragmatic injury is a commonly missed injury in trauma patients. Right-sided diaphragmatic injuries are less common due to the protective effect of bare area of liver and most series report incidence of 35%–49%. Here, we present two interesting cases of avulsion of the right hemidiaphragm.
| Case Reports|| |
Case report 1
A 10-year-old boy, run over by a trolley, presented after 5 days of trauma to our center in tachypneic state with a chest tube in situ and oxygen saturation of 80%, which improved to 98% with oxygenation. The child had blood pressure of 99/72 mmHg and tachycardia of 112 beats/min, with Glasgow Coma Score of 15/15. On examination, there were diminished breath sounds on the right hemithorax, and tenderness was present in the right upper abdomen with overlying abrasion. The chest X-ray showed right costophrenic angle blunting with a chest tube in situ and tenting of the right dome of the diaphragm. Contrast-enhanced computed tomography (CECT) of the chest and abdomen showed grade intravenous (IV) liver laceration, hemoperitoneum, and Grade III diaphragmatic injury with herniation of liver into right hemithorax. Atelectasis of the right lower lobe and right-sided moderate pleural effusion was also present. The patient was started on IV fluids and IV antibiotics. Avulsion injury of the right dome of the diaphragm was visualized on right posterolateral thoracotomy. The diaphragm was detached from parietes from midline anteriorly to posterior axillary line, and laceration of liver was also present [Figure 1] and [Figure 2]. Repair of the diaphragmatic injury was done by restoring attachment of diaphragm to the chest wall using polypropylene sutures. Liver laceration was not actively bleeding and hence did not require any repair. Right lung expanded fully on positive pressure ventilation. Postoperatively, the child had an uneventful recovery, and a follow-up chest X-ray after 3 months showed normal contour of the diaphragm and normal lung fields.

Case report 2
A 45-year-old female incurred multiple rib fractures with right-sided hemothorax following a road traffic accident, and a thoracostomy tube insertion was done at the primary treating hospital. The patient also had fractures of the right fibula and tibia which were managed with open reduction and internal fixation at the same center. A CECT thorax was done which showed second and third right rib fracture with collapse and consolidation of the right lung and laceration of the right lobe of liver with contusion. She was finally referred to our tertiary care center after 1½ months from the antecedent injury. On examination, she was conscious, oriented, pulse rate was 118/min, blood pressure was 108/82 mm Hg with severe dyspnea (respiratory rate of 25–30 breaths/min), and decreased air entries at the lung bases bilaterally. The patient was intubated and shifted to ICU for ventilatory support. A repeat Chest X Ray and CECT thorax showed bilateral multiple rib fractures, right-sided hemothorax with air foci in the collection, and an indistinct outline of the diaphragm [Figure 3] and [Figure 4]. The patient was taken up for exploration in view of a possible diaphragmatic injury, and right posterolateral thoracotomy was done. Intraoperatively, we found necrotic sloughed out the right dome of the diaphragm with collapsed right lung. An organized collection was present in the right hemithorax and the liver was lying in the lower thoracic cavity. All the necrotic tissues and organized hematomas were removed, and an intercostal tube was placed between liver and the collapsed lung. No repair of diaphragm could be done. Postoperatively, she had stable recovery but could not be weaned off mechanical ventilation. A tracheostomy was done in view of long-term intubation. Enteral feeds were started through nasogastric tube. The patient was transferred to the cardiothoracic surgery unit after 3 weeks for further management. However, in view of her poor general condition, no further surgery was performed and she died after 1 month.

| Discussion|| |
The incidence of diaphragmatic injury varies from 0.8% to 8%. Isolated diaphragmatic injury is rare with associated injury rate reaching up to 100%. Most morbidity and mortality are due to associated injuries. It is commonly associated with intra-abdominal injuries, thoracic injuries, fractures of the ribs, pelvis, and long bones, head injuries, and rarely aortic injuries.
A careful search for diaphragmatic injury in any suspected case of blunt or penetrating trauma abdomen should be the norm. All patients with wound entering Murray's Box, which is defined as area between nipple/inframammary fold to coastal margins below should be thoroughly evaluated. A simple chest X-ray showing pleural effusion, atelectasis, contusion, or diaphragmatic elevation is a red flag sign to suspect diaphragmatic injury. CECT chest is an excellent investigation. However, isolated diaphragmatic injury might still be missed. Diagnostic laparoscopy and thoracoscopy are new modalities for early diagnosis and repair of diaphragmatic injury at the same time. In case of further doubt, video-assisted thoracoscopy or laparotomy confirms a diaphragmatic rent.
Management involves exploratory laparotomy, reduction of the herniated contents with adhesiolysis, and repair of diaphragm with nonabsorbable sutures with or without nonabsorbable mesh. Thoracotomy might be needed to assess the integrity of suture line and adhesiolysis.
Alternative methods in a contaminated field include the use of biologic mesh, vascularized tissue flaps, or a temporary absorbable mesh with plans for a delayed reconstruction. However, massive gunshot wounds and diaphragmatic injuries are the challenges. Surgical options include relocating the hemidiaphragm at a higher level superior to the thoracic defect, effectively converting thoracic wound into abdominal one. Muscle flaps such as transverse abdominis, external oblique, and reverse latissimus dorsi are used to cover the wound. A sloughed diaphragm needs to be debrided and reinforced with mesh however with very high chances of infection in acute contaminated wound. Recent advances have allowed minimal access repair of diaphragmatic injuries including video-assisted thoracoscopic and robotic surgery.,
Thus, we conclude that early diagnosis of diaphragmatic injury results in better outcome. We also highlight that management options for totally devitalized hemidiaphragm with no support available to fix the mesh are abysmal. Thus, further trials to seek management options for such cases need to be done.
