Delayed right-sided diaphragmatic rupture and laparoscopic repair with mesh fixation

Robotic Transthoracic Repair of a Right-Sided Traumatic Diaphragmatic Rupture

Introduction  Traumatic diaphragm rupture injury repairs are predominately performed through thoracotomy, laparotomy, or a combination of the two approaches. While open surgery is often necessary to follow the fundamentals of damage-control operations in unstable or polytrauma patients, minimally invasive surgery may be an alternative for those with a low injury burden to reduce the postoperative morbidities associated with open operations. Case Description  We describe the first case of a right-sided diaphragm rupture from blunt trauma that was repaired by a robotic transthoracic approach in the index admission. Conclusion  Minimally invasive repair of an acute traumatic diaphragm rupture is feasible in selected trauma patients.

Dual mesh repair for a large diaphragmatic hernia defect: An unusual case report

•

Delayed right sided of diaphragm rupture or hernia is a rare.

•

Most of the diaphragmatic hernia patients are asymptomatic.

•

The main treatment approach is repair of the diaphragmatic hernia defect after reduction of the organs and tissues into the abdominal cavity.

•

A dual mesh repair can be used for a large diaphragm hernia.

Introduction

Diaphragmatic hernia secondary to traumatic rupture is a rare entity which can occur after stab wound injuries or blunt abdominal traumas. We aimed to report successfully management of dual mesh repair for a large diaphragmatic defect.

Case report

A 66-year-old male was admitted with a right sided diaphragmatic hernia which occurred ten years ago due to a traffic accident. He had abdominal pain with worsened breath. Chest X-ray showed an elevated right diaphragm. Further, thoraco-abdominal computerized tomography detected herniation a part of the liver, gallbladder, stomach, and omentum to the right hemi-thorax. It was decided to diaphragmatic hernia repair. After an extended right subcostal laparotomy, a giant right sided diaphragmatic defect measuring 25 × 15 cm was found in which the liver, gallbladder, stomach and omentum were herniated. The abdominal organs were reducted to their normal anatomic position and a dual mesh graft was laid to close the diaphragmatic defect. Patients’ postoperative course was uneventful.

Discussion

Diaphragmatic hernia secondary to trauma is more common on the left side of the diaphragm (left/right = 3/1). A right sided diaphragmatic hernia including liver, stomach, gallbladder and omentum is extremely rare. The main treatment of diaphragmatic hernias is primary repair after reduction of the herniated organs to their anatomical position. However, in the existence of a large hernia defect where primary repair is not possible, a dual mesh should be considered.

Conclusion

A dual mesh repair can be used successfully in extensive large diaphragmatic hernia defects when primary closure could not be achieved.

The Use of Biological Meshes in Diaphragmatic Defects - An Evidence-Based Review of the Literature

The widespread use of meshes for hiatal hernia repair has emerged in the era of laparoscopic surgery, although sporadic cases of mesh augmentation of traumatic diaphragmatic rupture have been reported. The indications for biologic meshes in diaphragmatic repair are ill defined. This systematic review aims to investigate the available evidence on the role of biologic meshes in diaphragmatic rupture and hiatal hernia repair. Limited data from sporadic case reports and case series have demonstrated that repair of traumatic diaphragmatic rupture with biologic mesh is safe technique in both the acute or chronic setting. High level evidence demonstrates short-term benefits of biologic mesh augmentation in hiatal hernia repair over primary repair, although adequate long-term data are not currently available. Long-term follow-up data suggest no benefit of hiatal hernia repair using porcine small intestine submucosa over suture repair. The effectiveness of different biologic mesh materials on hernia recurrence requires further investigation.

Laparoscopic correction of experimentally induced diaphragmatic rupture in dogs

PURPOSE

To describe the dog as a model for studying laparoscopic correction of experimental diaphragmatic ruptures.

METHODS

Five male dogs were used in this study. Under laparoscopic approach, a defect of 7 cm was created on the left ventral insertion of the diaphragm. Fourteen days after this procedure, the abdomen was explored using laparoscopic access and the diaphragmatic defect was corrected with intracorporeal suture. The dislocated organs, surgical time, and suturing time were recorded. Analgesia and clinical condition were monitored during the postoperative period.

RESULTS

All animals recovered well from the diaphragmatic rupture creation. After 14 days, abdominal organs (liver, spleen, omentum and/or intestine) were found inside the thoracic cavity in all animals. It was possible to reposition the organs and suture the defect by laparoscopic access in three animals. These animals showed excellent postoperative recovery. It was not possible to reposition the liver safely when it was friable.

CONCLUSIONS

Laparoscopic creation of diaphragmatic rupture in dogs is feasible. Dogs are a good model for training and studying the correction of experimentally created diaphragmatic rupture by the laparoscopic approach. A friable liver is a complicating factor that should be taken into account. Animals submitted to laparoscopic correction showed excellent postoperative recovery.

Video-assisted minithoracotomy for blunt diaphragmatic rupture presenting as a delayed hemothorax

Diaphragmatic ruptures after blunt trauma are rare life-threatening conditions. Most of them occur on the left-sided hemidiaphragm with herniation or associated organ injuries after a motor vehicle accident. We present an unusual case of blunt diaphragmatic rupture resulting in a delayed hemothorax. A 62-year-old man presented with acute dyspnea that initiated while straining to pass stool. He had a bruise on the lower back region of his right thorax after a slip-and-fall accident 7 days previously. Chest computed tomographic scans revealed a right-sided hemothorax without any evidence of herniation or associated organ injuries. Emergency surgery was performed through a video-assisted minithoracotomy. During surgery, we identified a diaphragmatic laceration with a severed blood vessel originating from the right superior phrenic artery. The lesion was repaired with interrupted horizontal mattress sutures. The total amount of bleeding was approximately 2000 mL. The patient had an uneventful recovery with no further bleeding episodes.
