Purpose: Diaphragmatic hernias (DHs) are divided into congenital and acquired hernias, most of which are congenital. Among acquired DHs, up to 80% are left-sided, only a few iatrogenic DHs have been reported, and bilateral hernias are extremely rare. For diagnostic reasons, many DHs are overlooked by ultrasonography or X-ray and are only recognized at a later stage when complications occur.
Methods: In 2009, we performed three partial diaphragm replacements in our clinic for repairing DHs using a PERMACOL™ implant.
Results: As all patients had uneventful postoperative courses and the clinical outcomes were very good, we present one special case of a 65-year-old male with a giant iatrogenic bilateral DH with an enterothorax.
Conclusion: We see a good indication for diaphragm replacements by using a PERMACOL™ implant for fixing especially DHs with huge hernial gaps and in cases with fragile tissue.

Non-traumatic diaphragmatic hernias (DHs) are mainly of congenital origin, whereas DHs in adults are seen in blunt (0.8%–5% incidence) or penetrating (10%–15% incidence) thoracoabdominal trauma.1–3 Among acquired DHs, up to 80% are left-sided, bilateral hernias are extremely rare, and only a few iatrogenic DHs have been reported.4 Most acquired DHs are caused by sternotomies in adult and pediatric cardiac surgery and abdominal surgery.5–10
The majority of traumatic or iatrogenic DHs manifest immediately or shortly after an accident. Despite there being various diagnostic tools, some hernias can still be overlooked and only recognized at a later stage when complications resulting from the herniated organs have manifested.2,11–14 Nevertheless, some develop long after the injury and only turn symptomatic after an interval of months or years.15,16 The main symptoms of DHs are abdominal/chest pain and dyspnea due to pulmonary compression, bowel obstruction and strangulation, which were present in our case.
Thoracotomy and/or laparotomy are often required in a hemodynamic unstable polytraumatic patient. However, thoracoscopy and/or laparoscopy have recently been suggested in the literature to be helpful for both the diagnosis and treatment of these lesions in order to reduce the high morbidity and mortality rates seen with open procedures.2,13,17–20 Although the closure technique for the hernia site is still a matter of discussion, direct closure without plastic seems to be favored by some authors.13,18
The reported patient is a 65-year-old male. During a vocal cord operation 10 years before, there was an accidental intralaryngeal gas explosion that required several subsequent tracheal reconstructions. Consequently, a huge bilateral diaphragmatic hernia developed over the years.
As the patient was suffering from progredient dyspnea, a computed tomography was performed, which showed a complete enterothorax (Figure 1); therefore, an operative approach was indicated. The upper abdomen was incised by transverse laparotomy revealing a large package of small intestine ventrally disappearing on both sides of the chest (Figure 2). The adhesions were divided and the parts of the colon and jejunum that were dislocated in the chest were repositioned into the abdomen. Some parts were partially strangulated but still in good shape. The stomach, however, was in the correct anatomical location. After repositioning and resection of the hernial sac, the hernial gap could hardly be adapted (Figure 3). The diaphragm was very weak, which suggested that a direct closure would be too fragile. For this reason, a large flap of PERMACOL™ (original size: 18 cm ×28 cm ×1.5 cm; Covidien Ltd, Dublin, Ireland) was trimmed to fit so that it covered both sides of the dorsal diaphragm and the ventral part of the flap overlapped with the abdominal wall incision (Figure 4). The flap was fixed all around with VICRYL™ 0 sutures (Johnson & Johnson, New Brunswick, NJ, USA; Figure 5). As a pneumothorax on the right side was provoked by the manipulation, thoracic drainage was applied. The abdominal wall was occluded involving the ventral edge of the PERMACOL™ flap to provide for more stability.

The postoperative course was uneventful apart from paroxysmal atrial fibrillation and the patient was released from hospital 16 days after operation.
The postoperative follow-up after 3 and 6 months including a computed tomography scan did not reveal any pathologies.
The interesting aspects of this case are the huge bilateral expansion of the DH and the unusual iatrogenic cause preceding the symptoms by 10 years.
The distinct weakness of the entire diaphragm – a hint of the chronic progress of the hernia – required reconstruction by an implant. Usually, synthetic mesh like polytetrafluoroethylene is used to close hernial gaps but also other material is sometimes used. In this case, we decided to use a large porcine dermal collagen flap which serves as a matrix for cell ingrowth and neovascularization, because of its very good biocompatibility. Even though there was a previous report about the rejection of a PERMACOL™ implant used in abdominal wall repair, in our case, we had no postoperative complications or any hernia relapse.21
Based on our experience, PERMACOL™ implants are a good choice for diaphragm replacements especially for fixing DHs with huge hernial gaps and in cases with fragile tissue.
Finally, prospective and randomized trials have to be performed to resolve the pros and cons of this procedure.
