Abstract
OBJECTIVE This systematic review aims to evaluate current choices in practice and outcomes of biomaterials used in patch repair of congenital diaphragmatic hernia (CDH). BACKGROUND Multiple biomaterials, both novel and combinations of pre-existing materials are employed in patch repair of large size CDHs. METHODS A literature search was performed across Embase, Medline, Scopus, and Web of Science. Publications that explicitly reported patch repair, material used, and recurrences following CDH repair were selected. RESULTS Sixty-three papers were included, presenting data on 4595 patients, of which 1803 (39.2%) were managed using 19 types of patches. Goretex® (GTX) (n=1106) was the most frequently employed patch followed by Dualmesh® (n=267), Surgisis® (n=156), Marlex®/GTX® (n=56), Tutoplast dura® (n=40), Dacron® (n=34), Dacron®/GTX® (n=32), Permacol® (n=24), Teflon® (n=24), Surgisis®/GTX® (n=15), Sauvage® Filamentous Fabric (n=13), Marlex® (n=9), Alloderm® (n=8), Silastic® (n=4), Collagen coated Vicryl® mesh (CCVM) (n=1), Mersilene® (n=1), and MatriStem® (n=1) Biomaterials were further subgrouped as: synthetic nonresorbable (SNOR) (n=1458), natural resorbable (NR) (n=241), combined natural and synthetic nonresorbable (NSNOR) (n=103), and combined natural and synthetic resorbable (NSR) (n=1). The overall recurrence rate for patch repair was 16.6% (n=299). For patch types with n>20, recurrence rate was lowest in GTX/Marlex (3.6%), followed by Teflon (4.2%), Dacron (5.6%), Dualmesh (12.4%), GTX (14.8%), Permacol (16.0%), Tutoplast Dura (17.5%), SIS/GTX (26.7%), SIS (34.6%), and Dacron/GTX (37.5%).When analyzed by biomaterial groups, recurrence was highest in NSR (100%), followed by NR (31.5%), NSNOR (17.5%), and SNOR the least (14.0%). CONCLUSION In this cohort, over one-third of CDH were closed using patches. To date, 19 patch types/variations have been employed for CDH closure. GTX is the most popular, employed in over 60% of patients; however, excluding smaller cohorts (n<20), GTX/Marlex is associated with the lowest recurrence rate (3.6%). SNOR was the material type least associated with recurrence, while NSR experienced recurrence in every instance.

Abstract
BACKGROUND Patch repair of congenital diaphragmatic hernia (CDH) using Gore-Tex® is associated with infection, adhesions, hernia recurrence, long-term musculoskeletal sequels and poor tissue regeneration. To overcome these limitations, the performance of two novel biodegradable membranes was tested to repair CDH in a growing pig model. METHODS Twelve male pigs were randomly assigned to 3 different groups of 4 animals each, determined by the type of patch used during thoracoscopic diaphragmatic hernia repair (Gore-Tex®, polycaprolactone electrospun membrane-PCLem, and decellularized human chorion membrane-dHCM). After 7 weeks, all animals were euthanized, followed by necropsy for diaphragmatic evaluation and histological analysis. RESULTS Thoracoscopic defect creation and diaphragmatic repair were performed without any technical difficulty in all groups. However, hernia recurrence rate was 0% in Gore-Tex®, 50% in PCLem and 100% in dHCM groups. At euthanasia, Gore-Tex® patches appeared virtually unchanged and covered with a fibrotic capsule, while PCLem and dHCM patches were replaced by either floppy connective tissue or vascularized and floppy regenerated membranous tissue, respectively. CONCLUSION Gore-Tex® was associated with a higher survival rate and lower recurrence. Nevertheless, the proposed biodegradable membranes were associated with better tissue integration when compared with Gore-Tex®.

Abstract
Laparoscopic repair of recurrent diaphragmatic hernia is infrequently reported. We report successful laparoscopic management of such a case in a 23-year-old male who presented with recurrent vomiting and hiccoughs. He had suffered a gun-shot injury to the chest 2 years ago, following which a primary diaphragmatic repair was done by laparotomy and thoracotomy. The patient developed recurrent left diaphragmatic hernia, which was repaired using polypropylene mesh using a laparoscopic approach. At 6 months of follow-up, the patient is doing well, and his symptoms have resolved. Laparoscopic repair of recurrent diaphragmatic hernia is feasible.

Allogenic tissue-specific decellularized scaffolds promote long-term muscle innervation and functional recovery in a surgical diaphragmatic hernia model. Acta Biomater 2019; 89:115-125. [PMID: 30851456 DOI: 10.1016/j.actbio.2019.03.007] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 02/22/2019] [Accepted: 03/05/2019] [Indexed: 01/08/2023]
Abstract
Congenital diaphragmatic hernia (CDH) is a neonatal defect in which the diaphragm muscle does not develop properly, thereby raising abdominal organs into the thoracic cavity and impeding lung development and function. Large diaphragmatic defects require correction with prosthetic patches to close the malformation. This treatment leads to a consequent generation of unwelcomed mechanical stress in the repaired diaphragm and hernia recurrences, thereby resulting in high morbidity and significant mortality rates. We proposed a specific diaphragm-derived extracellular matrix (ECM) as a scaffold for the treatment of CDH. To address this strategy, we developed a new surgical CDH mouse model to test the ability of our tissue-specific patch to regenerate damaged diaphragms. Implantation of decellularized diaphragmatic ECM-derived patches demonstrated absence of rejection or hernia recurrence, in contrast to the performance of a commercially available synthetic material. Diaphragm-derived ECM was able to promote the generation of new blood vessels, boost long-term muscle regeneration, and recover host diaphragmatic function. In addition, using a GFP + Schwann cell mouse model, we identified re-innervation of implanted patches. These results demonstrated for the first time that implantation of a tissue-specific biologic scaffold is able to promote a regenerating diaphragm muscle and overcome issues commonly related to the standard use of prosthetic materials. STATEMENT OF SIGNIFICANCE: Large diaphragmatic hernia in paediatric patients require application of artificial patches to close the congenital defect. The use of a muscle-specific decellularized scaffold in substitution of currently used synthetic materials allows new blood vessel growth and nerve regeneration inside the patch, supporting new muscle tissue formation. Furthermore, the presence of a tissue-specific scaffold guaranteed long-term muscle regeneration, improving diaphragm performance to almost complete functional recovery. We believe that diaphragm-derived scaffold will be key player in future pre-clinical studies on large animal models.

Abstract
Surgical repair of large muscular defects requires the use of autologous graft transfer or prosthetic material. Naturally derived matrices are biocompatible materials obtained by tissue decellularization and are commonly used in clinical practice. Despite promising applications described in the literature, the use of acellular matrices to repair large defects has been only partially successful, highlighting the need for more efficient constructs. Scaffold recellularization by means of tissue engineering may improve not only the structure of the matrix, but also its ability to functionally interact with the host. The development of such a complex construct is challenging, due to the complexity of the native organ architecture and the difficulties in recreating the cellular niche with both proliferative and differentiating potential during growth or after damage. In this study, we tested a mouse decellularized diaphragmatic extracellular matrix (ECM) previously described by our group, for the generation of a cellular skeletal muscle construct with functional features. The decellularized matrix was stored using different conditions to mimic the off‐the‐shelf clinical need. Pediatric human muscle precursors were seeded into the decellularized scaffold, demonstrating proliferation and differentiation capability, giving rise to a functioning three‐dimensional skeletal muscle structure. Furthermore, we exposed the engineered construct to cardiotoxin injury and demonstrated its ability to activate a regenerative response in vitro promoting cell self‐renewal and a positive ECM remodeling. Functional reconstruction of an engineered skeletal muscle with maintenance of a stem cell pool makes this a promising tool toward future clinical applications in diaphragmatic regeneration. stem cells translational medicine2019;8:858&869

Abstract
This review focuses on the surgical viewpoints on patch repairs in neonates with large congenital diaphragmatic hernia defects. The main focus is on the various biomaterials that have been employed to date with regard to their source of origins, degradation properties as well as tissue integration characteristics. Further focus is on the present knowledge on patch integration when biomaterials are placed in the diaphragmatic defect. The review will also look at the present evidence on the biomechanical characteristics of the most commonly used biomaterials and compares these materials to diaphragmatic tissue to offer more insight on the present practice of patch repairs in large defects. Since tissue engineering and regenerative medicine has offered another dimension to diaphragmatic replacement, a detailed overview of this technology will be undertaken with regard to cell sourcing, scaffolds, in vitro versus in vivo implants as well as quality of tissue produced, to explore the limitations and the feasibility facing the scientific community in its clinical implementation of skeletal muscle-engineered tissue beyond laboratory research for diaphragmatic replacement.

Abstract
INTRODUCTION The use of prosthetic patches of non-absorbable materials represents a valid tool in the treatment of abdominal wall and diaphragmatic defects in pediatric age. In recent years research has developed biological dermal scaffolds made from a sheet of acellular matrix that can provide the desired support and reduce the occurrence of complications from non-absorbable implant. We present our experience and a systematic review to evaluate the use of biologic prosthesis for abdominal wall closure in pediatric patients. METHODS The study from January 2009 to January 2015 involved 20 patients treated with Permacol™ implant. We observed postoperative complications only in patients treated for abdominal wall closure, which is the major indication for the use of Permacol™. We conducted a systematic review and meta-analysis (according to PRISMA) on PubMed/Medline, Scopus and EMBASE regarding the use of biological prosthesis in pediatric population considering the incidence of complications as the primary outcome. RESULTS 3/20 patients experienced complications: 2 patients with skin necrosis healed conservatively and 1 of them developed laparocele. Thus only 1 patient with incisional hernia had significant surgery complication. In patients who were permanently implanted with Permacol™ it has not determined adverse reactions with optimal functional outcome. CONCLUSIONS In accordance with the few data (case reports and case series) reported in literature about pediatric patients, our experience in different pathologies and applications has shown the effectiveness of Permacol™, in particular for the non-occurrence of infections, that often affect the use of prosthesis.

Abstract
Large diaphragmatic defects can be repaired with latissimus dorsi and serratus anterior muscle flaps. We report the first successful primary repair of complete congenital diaphragmatic agenesis using a combination of autologous living bio-tissue and synthetic mesh in a neonate born in the NMC Specialty Hospital in Dubai, United Arab Emirates, in May 2014. Poor Apgar scores, a scaphoid abdomen and absent breath sounds over the right hemithorax were observed at birth. Chest and abdominal X-rays revealed a diaphragmatic hernia. The neonate was stabilised using high-frequency oscillatory ventilation, nitric oxide and sildenafil. The right diaphragm was reconstructed using combined latissimus dorsi and serratus anterior muscle flaps reinforced by a flexible composite mesh. At 12 months old, the infant had normal respiratory function and the diaphragm was intact. No disabilities of the shoulder or scapula were observed. This case indicates that a combination of living tissue and synthetic mesh can be used to reconstruct a functional diaphragm with efficient pleuroperitoneal separation.

Abstract
Development of novel prognostic, diagnostic, and treatment options will provide major benefits for millions of patients with acute or chronic respiratory dysfunction, cardiac-related disorders, esophageal problems, or other diseases in the thorax. Allogeneic organ transplant is currently available. However, it remains a trap because of its dependency on a very limited supply of donated organs, which may be needed for both initial and subsequent transplants. Furthermore, it requires lifelong treatment with immunosuppressants, which are associated with adverse effects. Despite early clinical applications of bioengineered organs and tissues, routine implementation is still far off. For this review, we searched the PubMed, MEDLINE, and Ovid databases for the following keywords for each tissue or organ: tissue engineering, biological and synthetic scaffold/graft, acellular and decelluar(ized), reseeding, bioreactor, tissue replacement, and transplantation. We identified the current state-of-the-art practices in tissue engineering with a focus on advances during the past 5 years. We discuss advantages and disadvantages of biological and synthetic solutions and introduce novel strategies and technologies for the field. The ethical challenges of innovation in this area are also reviewed.

Abstract
A diaphragmatic hernia is usually seen in childhood and it is rare in adults. We are reporting a case of a 73 years old male who presented with pain and distension of the abdomen, breathlessness and constipation. He was operated 10 years back for a diaphragmatic hernia, during which a splenectomy, omentectomy and a mesh repair were done. X-rays and CT scans of the chest and the abdomen showed a recurrent diaphragmatic hernia on the left side. Laparotomy and left sided thoracotomy was done. The contents being the small bowel and the colon, they were reduced. The left hemi-diaphragm was completely absent, except for an anterior thin rim of tissue. A short ischaemic jejunal segment was resected. A dual mesh was used to reconstruct the left hemi-diaphragm in a contaminated field and it was fixed to the intact rim and to the other available tissues around the defect. The post-operative chest X-rays showed the mesh to be in place. The patient had an uneventful recovery. No signs of recurrence were found during 2 years of followup. Adult diaphragmatic hernias, once they are diagnosed, are managed surgically to prevent complications. Difficult scenarios may be encountered, for which the surgical strategy should be individualized and the immediate postoperative complications should be dealt appropriately.

Abstract
Surgical management of congenital diaphragmatic hernia (CDH) remains a challenge for all clinicians. While the treatment strategies for CDH have evolved from emergent surgical intervention to initial hemodynamic stabilization with delayed surgical repair, surgical innovations have remained limited in the last 20 years. Advances in surgical approaches, such as minimally invasive surgery and alternatives to diaphragmatic replacement, have focused on improvements in surgical morbidity.

Abstract
CONGENITAL DIAPHRAGMATIC HERNIAS (CDHS) OCCUR MAINLY IN TWO LOCATIONS: the foramen of Morgagni and the more common type involving the foramen of Bochdalek. Hiatal hernia and paraesophageal hernia have also been described as other forms of CDH. Pulmonary hypertension and pulmonary hypoplasia have been recognized as the two most important factors in the pathophysiology of congenital diaphragmatic hernia. Advances in surgical management include delayed surgical approach that enables preoperative stabilization, introduction of fetal intervention due to improved prenatal diagnosis, the introduction of minimal invasive surgery, in addition to the standard open repair, and the use of improved prosthetic devices for closure.

Abstract
The authors present a rare case of congenital diaphragmatic Bochdalek hernia in an adult stimulating left pleural effusion. The diagnosis of left pleural effusion was made on the basis of conventional chest X-ray and ultrasonography. The definitive diagnosis of Bochdalek hernia was made by left video-assisted thoracoscopy. The patient was successfully treated operatively by conventional surgery--a combination of left thoracotomy and median laparotomy. The reported case supported the view that Bochdalek hernia in adults presents usually with atypical chronic abdominal and respiratory symptoms. Surgical treatment should best be performed, according to the authors, by competent surgeons with good command of both the thoracic and abdominal approaches to the diaphragm.

Abstract
Introduction Traumatic diaphragmatic hernias are an unusual presentation of trauma, and are observed in about 10% of diaphragmatic injuries. The diagnosis is often missed because of non-specific clinical signs, and the absence of additional intra-abdominal and thoracic injuries. Case presentation We report a case of a 59-year-old Italian man hospitalized for abdominal pain and vomiting. His medical history included a blunt trauma seven years previously. A chest X-ray showed right diaphragm elevation, and computed tomography revealed that the greater omentum, a portion of the colon and the small intestine had been transposed in the hemithorax through a diaphragm rupture. The patient underwent laparotomy, at which time the colon and small intestine were reduced back into the abdomen and the diaphragm was repaired. Conclusions This was a unusual case of traumatic right-sided diaphragmatic hernia. Diaphragmatic ruptures may be revealed many years after the initial trauma. The suspicion of diaphragmatic rupture in a patient with multiple traumas contributes to early diagnosis. Surgical repair remains the only curative treatment for diaphragmatic hernias. Prosthetic patches may be a good solution when the diaphragmatic defect is severe and too large for primary closure, whereas primary repair remains the gold standard for the closure of small to moderate sized diaphragmatic defects.
