BACKGROUND: Doxycycline, a nonspecific metalloproteinase (MMP) inhibitor, has been demonstrated to impact the strength of the polypropylene (PP) mesh-repaired hernia with an increase in the deposition of collagen type 1. The impact of doxycycline with porcine acellular dermal matrices (PADM) is unknown; therefore, we evaluated the impact of doxycycline administration upon hernia repair with PP and PADM mesh. METHODS: Sprague-Dawley rats weighing ~400 g underwent laparotomy with creation of a midline ventral hernia...

BACKGROUND: Over 100 types of soft tissue repair materials are commercially available for hernia repair applications. These materials vary in characteristics such as mesh density, pore size, and pore shape. It is difficult to determine the impact of a single variable of interest due to other compounding variables in a particular design. Thus, the current study utilized prototype meshes designed to evaluate each of these mesh parameters individually. METHODS: Five prototype meshes composed of planar, monofilament polyethylene terephthalate (PET) were evaluated in this study...

BACKGROUND: Ventral and incisional hernias are common surgical problems and their repairs are among the common surgeries done by a general surgeon. Repair of a large ventral hernia is still associated with high postoperative morbidity and recurrence rates. No single approach to ventral hernia repair will be the best choice for all patients. Large ventral hernias are often better approached with open surgery but may still be problematic when the defect is too wide for primary fascial closure to be achieved, as this leaves mesh exposed, bridging the gap...

BACKGROUND: Body mass index does not allow accurate risk stratification for individuals undergoing component separation repair of ventral hernias. The authors hypothesized that tissue morphology measurements (morphomics) of preoperative computed tomography scans stratify the risk of surgical site infection in patients undergoing ventral hernia repair with a component separation technique. METHODS: The authors identified 93 patients who underwent component release ventral hernia repair (2004 to 2012)...

BACKGROUND: The management of major omphalocoele and large incisional hernias is a common problem and constitutes a great challenge for paediatric surgeons. In most cases, the abdominal cavity is so small and does not allow immediate reduction. Prosthetic materials are becoming increasingly popular for such repair, but direct contact between the bowel and these synthetic materials carries the risk of adhesions and intestinal obstruction. The relatively new PROCEED mesh with absorbable layer in contact with the bowel and another polypropylene non-absorbable layer against the abdominal wall may not produce such adhesions...

BACKGROUND: Synthetic mesh has significantly reduced recurrence rates for ventral hernia repair; however, prosthetic mesh infections remain a significant complication. We hypothesized that unique mesh constructs might alter the ability of various synthetic meshes to clear bacterial contamination. To evaluate this, we studied commercially available synthetic meshes ability to clear a bacterial contamination with methicillin resistant Staphylococcus aureus infection. METHODS: Two hundred and eighty-three rats underwent hernia repair with one of nine synthetic materials...

Intraperitoneal surgical mesh implantation is required for laparoscopic ventral hernia repair. Composite meshes are well known in animal models and human practice. The aim of our study is to compare the biological behaviour of two different textured silicone-covered polypropylene meshes. Transmural abdominal wall defect was created in 40 rabbits and treated as follows: In 20 animals a polypropylene mesh with a laminar silicone covering (LSPP) and in the rest a macroporous textured mesh knitted of silicone-impregnated polypropylene filaments (MSPP) was applied...

BACKGROUND: Although still under development, single-port access (SPA) approach may be of interest in patients prone to port-side incisional hernia, ensuring absence of increased fascial incision. This forms the basis for evaluating SPA for prosthetic ventral hernia repair. We report a new SPA technique of ventral hernia repair using working-channel endoscope, standard laparoscopic instruments, and 10-mm port. METHODS: Prospective experience with SPA prosthetic repair of primary and incisional ventral hernia in 52 patients for 55 ventral hernias is presented...

OBJECTIVE: To review mesh products currently available for ventral hernia repair and to evaluate their efficacy in complex repair, including contaminated and reoperative fields. BACKGROUND: Although commonly referenced, the concept of the ideal prosthetic has never been fully realized. With the development of newer prosthetics and approaches to the ventral hernia repair, many surgeons do not fully understand the properties of the available prosthetics or the circumstances that warrant the use of a specific mesh...
