Long-term results after laparoscopic repair of traumatic diaphragmatic hernias

Laparoscopically assisted repair of an acute traumatic diaphragmatic hernia

A 60-year-old man with chronic obstructive pulmonary disease and a heavy smoker and drinker presented to the emergency department with left-sided thoracoabdominal pain after falling down the stairs. Initial clinical findings were left-sided chest tenderness with no clinical evidence of subcutaneous emphysema. Twenty-four hours later the patient's respiratory distress increased-repeat chest X-ray showed a left gastrothorax indicative of a ruptured left hemi diaphragm. Diagnostic laparoscopy in the supine position via an umbilical port confirmed the presence of the stomach, spleen and splenic flexure of the colon in the left chest. Laparoscopic reduction of the stomach and colon was performed, but a small upper midline incision was required to reduce the spleen without injury. The diaphragmatic tear was repaired by direct open suture. The patient required a brief period of postoperative ventilation via a tracheostomy. The patient remained well at a 3-month follow-up visit.

Chronic traumatic diaphragmatic hernia

Chronic traumatic diaphragmatic hernia is an uncommon but persistent diagnosis associated with significant morbidity and mortality. Chronic TDH describes a spectrum of disease in antecedent mechanism of injury, timing of presentation, size of diaphragmatic defect, and amount and type of tissue displaced into the chest. Multiplanar CT with coronal, sagittal, and axial reconstruction is most effective in making this diagnosis. Once diagnosed, repair should be undertaken. Although transabdominal approaches may be successful, the authors prefer an open transthoracic approach, recognizing that either approach may need to incorporate access into the other body cavity to complete the repair. Basic hernia principles apply including the construction of a tension-free repair, which may necessitate the use of prosthetics. As surgeons become increasingly comfortable with minimally invasive techniques, more chronic TDH are likely to be approached in this fashion. Finally, as much of the morbidity and mortality is associated with the catastrophic consequences of chronic TDH, vigilance needs to be applied in an attempt to diagnose and then repair TDH while in the latent stage prior to the development of the catastrophic complications that herald the obstructive stage.

Traumatic diaphragmatic hernia: tertiary centre experience

BACKGROUND

Traumatic diaphragmatic hernia (TDH) resulting from traumatic diaphragmatic rupture (TDR) may not be easily detected and can lead to significant morbidity and mortality.

PATIENTS AND METHODS

A retrospective case note analysis was performed of all patients treated for TDR at a major teaching hospital between March 2003 and March 2008. The aetiological factors, associated injuries, management and outcome were analysed.

RESULTS

Twenty-seven patients were studied (24 males, 3 females) and their ages ranged from 16 to 72 years (median 35 years). TDR was left-sided in 85% and right-sided in 15%. Aetiology was blunt trauma in 81% and 19% had penetrating injury. Associated injuries were present in 81%. The most common approach for repair was transabdominal (89%); additional thoracotomy was needed in 11%. Herniation of abdominal contents was present in 85% and herniation of more than one organ was present in 57%. The diaphragmatic rent was repaired primarily in 89% using nonabsorbable sutures. Post-operative pulmonary complications occurred in 52% of patients. Three patients (11%) died.

CONCLUSION

Left-sided blunt traumatic diaphragmatic rupture was more common than right-sided rupture. The most commonly herniated organs were the stomach and colon. Most ruptures could be repaired by an abdominal approach, which also allowed a complete exploration of the abdominal organs. Careful attention should be given to associated intra-abdominal injuries. Most of the defects were repaired directly using nonabsorbable sutures.

The role of laparoscopy in the diagnosis and the treatment of missed diaphragmatic hernia after penetrating trauma

BACKGROUND

The traumatic diaphragmatic hernia (TDH) may appear acutely after a blunt or penetrating trauma, or it can remain missed also for many years. The discussion about the utility of a laparoscopic repair in acute and chronic TDH is controversial.

METHODS

In this paper, we present two cases of chronic TDH that were successfully treated with laparoscopy. The first patient was treated 1 year after a stab wound and the second one 10 years after a firearm injury.

RESULTS

In both cases, the diaphragmatic defects were easily laparoscopically detected and treated. The defects were repaired with a direct running suture owing to the acceptable dimensions of the tears. The mean operative time was 135 minutes (range, 75-195). The blood loss during the operations was unremarkable. No intraoperative complications occurred, and the conversion rate was null. The postoperative course was uneventful in the first patient, whereas the second patient, owing to the intraoperative respiratory problems, needed an accurate respiratory monitoring in the Intensive Care Unit. The mean length of stay after the operation was 7 days (range, 6-8). At follow-up, the clinical examination and the chest X-rays documented no recurrence.

CONCLUSIONS

We recommend the use of laparoscopy in left chronic TDH repair, performing a direct suture of the diaphragm when possible.

Rotura traumática del diafragma

Traumatic diaphragmatic rupture is an infrequent lesion that can result from penetrating or blunt trauma to the abdomen or chest. Early diagnosis continues to be a challenge and this type of injury is associated with high morbidity and mortality. Preoperative diagnosis is difficult and a high level of suspicion, careful scrutiny of the chest x-ray, and early surgical treatment are required for successful management. We present a case of rupture of the left hemidiaphragm that was diagnosed and treated successfully within the first few hours. We also review the literature on controversial issues in the diagnosis and treatment of this injury.

Blunt traumatic diaphragmatic injuries in children

Diaphragmatic injuries following blunt trauma are rare. From January 1988 to February 2002 eight children were treated at the Children's Hospital at Westmead for diaphragmatic injury. Male to female ration was 5:3. Motor vehicle crashes were the most common cause. The injury was left-sided in four, right sided in three and central in one. Initial plain radiograph and computerised tomography detected the injury in 50% of cases. Laparotomy, contrast study and autopsy identified the rupture in one each. Associated injuries were present in all cases. Seven children had laparotomy and repair of the diaphragmatic rupture. The commonest site of rupture was posterolateral (37.5%). Diagnosis was delayed in two cases. There were two deaths (25% mortality) in the series, both due to associated injuries. Although rare, diaphragmatic rupture must be considered in any child with thoracoabdominal injury. Diagnosis may be difficult and require extensive investigation. Mortality usually results from associated injuries.

Minimally invasive surgery in trauma: technology looking for an application

BACKGROUND

Minimally invasive surgery has achieved pre-eminence for certain operations in general surgery over the last two decades, as the reduction in surgical insult has produced faster recovery with enhanced patient satisfaction and favourable health economics. Minimally invasive techniques have been less enthusiastically adopted by the trauma surgical community, despite some evidence of efficacy for nearly 40 years.

METHODS

The literature on minimally invasive techniques in trauma was reviewed.

RESULTS AND CONCLUSIONS

To date, minimally invasive surgery has played only a small role in trauma surgery. As clearer indications emerge and technology improves, surgeons should be encouraged to incorporate laparoscopy and video-assisted thoracoscopy (VATS) into their protocols and gain familiarity and expertise with their use.
