Symptomatic heterotopic ossification of abdominal surgical incisions is a rare occurrence. We present a 67-year-old man with severe discomfort caused by heterotopic ossification extending from the xiphoid to the umbilicus. The patient underwent an abdominal aortic aneurysm repair 3 years before our treatment. A 13 × 3.5 cm ossified lesion was excised. The resulting midline defect was closed using component separation and inlay Strattice. Tension-free midline adaptation of the recti muscles was achieved...

BACKGROUND: Bioprosthetics derived from human or porcine dermis and intestinal submucosa have dense, homogenous, aporous collagen structures that potentially limit cellular penetration, undermining the theoretical benefit of a "natural" collagen scaffold. We hypothesized that Miromesh-a novel prosthetic derived from porcine liver by perfusion decellularization-provides a more optimal matrix for tissue ingrowth. METHODS: Thirty rats underwent survival surgery that constituted the creation of a 4 × 1 cm abdominal defect and simultaneous bridged repair...

The management of giant omphaloceles at our department is primarily conservative. However, management can be challenging if the omphalocele is ruptured or the sac has to be removed. We report a case in which a giant omphalocele in a newborn female patient was managed by covering the abdominal defect with non-cross-linked intact porcine-derived acellular dermal matrix (Strattice reconstructive tissue matrix, LifeCell Corp., Branchburg, New Jersey, United States) sutured to the fascia combined with vacuum therapy...

Biological alternatives to synthetic meshes are increasingly utilised in complex abdominal wall reconstruction. There is a lack of evidence demonstrating that non-cross-linked porcine acellular dermal matrix vascularizes and integrates with human tissue in suboptimal wound conditions. We aimed to evaluate these properties in Strattice™ (Life Cell Inc., Branchburg, NJ) following ventral hernia repair. A retrospective review of patients with high-risk ventral hernia repair utilising Strattice™ as an onlay after open component separation was conducted...

BACKGROUND: A variety of prosthetic materials are used in the pediatric population for abdominal and chest wall reconstruction. Pediatric experience of non-cross-linked porcine acellular dermal matrix is limited to patients following liver transplantation. We review our outcomes in patients in whom this matrix was used. METHODS: A retrospective analysis of patients who underwent abdominal and chest wall reconstruction with a non-cross-linked porcine acellular dermal matrix (Strattice TM) was performed to assess clinical outcomes...

INTRODUCTION: Acellular Dermal Matrix (ADM) assisted breast reconstruction has transformed the single-stage Immediate Breast Reconstruction (IBR) with an impact on the cosmetic outcomes. However, there is limited data available on patient reported outcomes. This study highlights the Patient Reported Outcome Measures (PROMs), post-operative complications and lessons learnt from ADM assisted single-stage immediate breast reconstruction. METHODS: This prospective study enrolled consecutive patients from Feb 2012 - May 2015 undergoing mastectomy with direct-to-implant ADM assisted breast reconstruction, using Strattice™ (Acelity, San Antonio, TX, USA)...

BACKGROUND: Acellular dermal matrices (ADM) such as Strattice(TM) are increasingly used in UK during implant-based reconstruction. However, there are mixed opinions regarding the compatibility of radiotherapy treatment in pre- and post-reconstructed breasts. The aims of this study are to audit the rates of radiation induced complications in patients who underwent breast reconstruction using Strattice(TM) and establish whether there is an association between timing of radiotherapy and complication rates...

BACKGROUND: Bioprostheses represent a significant advance in the abdominal wall reconstruction since they become degraded until their complete elimination in the recipient organism. This study examines remodeling in the host of three noncrosslinked porcine dermal collagen biomeshes: Strattice™ (St; LifeCell Corp.), XCM Biologic® Tissue Matrix (XCM; Synthes CMF) and Protexa® (Pr; Deco Med S.R.L.). METHODS: Partial ventral hernia defects created in New Zealand White rabbits were repaired using the biomeshes that were placed in an inlay, preperitoneal position...

BACKGROUND: Recurrence after ventral hernia repair (VHR) remains a multifactorial problem still plaguing surgeons today. Some of the many contributing factors include mechanical strain, poor tissue-mesh integration, and degradation of matrices. The high recurrence rate witnessed with the use of acellular dermal matrices (ADM) for definitive hernia repair has reduced their use largely to bridging repair and breast reconstruction. Modalities that improve classic cellular metrics of successful VHR could theoretically result in improved rates of hernia recurrence; autologous platelet-rich plasma (PRP) may represent one such tool, but has been underinvestigated for this purpose...

BACKGROUND: High recurrence rates because of poor tissue incorporation limit the use of acellular dermal matrices (ADMs) in ventral hernia repair (VHR). Platelet rich plasma (PRP) is a growth factor-rich autologous blood product known to enhance tissue repair through cellular proliferation and neovascularization. We sought to study the effect of PRP on a porcine noncross-linked ADM in an in vivo model of VHR. We hypothesized that PRP would enhance ADM-tissue incorporation in a rat model of VHR...

Coccygeal herniation after coccygectomy is rare. Little is known about the management of this complication. We present a case of a 44 year old women with a coccygeal herniation 7 years after coccygectomy. She was treated two times for an infected pilonidal sinus with incision and drainage. After the last incision and drainage she had complaints of a painful swelling in the sacral area and difficulty with evacuation of her stools. A defaecography showed a coccygeal herniation. An additional MRI of the pelvic region showed a defect with a diameter of approximately 38mm...

INTRODUCTION: Complex hernias continue to present a challenge. Surgical techniques for repair are carefully considered to reduce risk for complications. Laparoscopic repairs improve postoperative infection rates, and placement of biologic mesh decreases mesh infection rates. However, laparoscopic repairs using biologic mesh is generally challenging due to difficulty with maneuverability. PRESENTATION OF CASE: We present a case of a complex ventral hernia that was laparoscopically repaired using a new FDA cleared laparoscopic biologic graft...

BACKGROUND AIMS: Complex injuries of the upper and lower extremities often result in scarring and subsequent adhesion formation, which may cause severe pain and distinctly reduce range of motion. In revision surgery, replacement of the missing subcutaneous tissue is desirable to prevent new adhesions, to cushion scarred tendons and nerves and to regain tissue elasticity. Therefore, the objective of this study was the in vitro evaluation of cell-seeded collagen matrices to serve as the basis for the reconstruction of the subcutaneous adipose tissue layer...

BACKGROUND: Porcine and bovine acellular dermal matrices (PADM and BADM, respectively) are the most commonly used biologic meshes for ventral hernia repair. A previous study suggests a higher rate of intraoperative device failures using PADM than BADM. We hypothesize that this difference is, in part, related to intrinsic mechanical properties of the matrix substrate and source material. The following study directly compares these 2 matrices to identify any potential differences in mechanical properties that may relate to clinical outcomes...
