BACKGROUND: In ventral hernia repair, when prosthetic material is placed intraperitoneally, it may lead to an inflammatory reaction resulting in adhesions between the mesh and abdominal viscera. Several meshes have been developed to minimize this process. In this experimental study, the ability of different combined meshes to attenuate the adhesion formation was examined. METHODS: Three commercially available lightweight porous combined meshes were placed intraperitoneally to repair an abdominal wall defect in rats: DynaMesh-IPOM (PVDF + PP), TiMesh (titanium-coated filament PP) and C-QUR/FX (omega-3 fatty acid-coated filament PP)...

INTRODUCTION Laparoscopic incisional and ventral hernia repair (LIVHR) is widely accepted and safe but the type of mesh used is still debated. We retrospectively compared postoperative outcomes with two different meshes commonly used in LIVHR. METHODS This is a retrospective study of patients who underwent incisional hernia repair between January 2008 and December 2010. Two meshes were used: Parietex™ Composite (Covidien, New Haven, CT, USA) and the DynaMesh(®)-IPOM (FEG Textiltechnik mbH, Aachen, Germany)...

The aim of this study was to obtain information about the mechanical properties of six meshes commonly used for hernia repair (Surgipro(®), Optilene(®), Infinit(®), DynaMesh(®), Ultrapro™ and TIGR(®)) by planar biaxial tests. Stress-stretch behavior and equibiaxial stiffness were evaluated, and the anisotropy was determined by testing. In particular, equibiaxial test (equal simultaneous loading in both directions) and biaxial test (half of the load in one direction following the Laplace law) were selected as a representation of physiologically relevant loads...

Use of textile structures for reinforcement of pelvic floor structures has to consider mechanical forces to the implant, which are quite different to the tension free conditions of the abdominal wall. Thus, biomechanical analysis of textile devices has to include the impact of strain on stretchability and effective porosity. Prolift(®) and Prolift + M(®), developed for tension free conditions, were tested by measuring stretchability and effective porosity applying mechanical strain. For comparison, we used Dynamesh-PR4(®), which was designed for pelvic floor repair to withstand mechanical strain...

PURPOSE: Current hernia literature shows that the use of mesh in ventral hernia repair reduces the risk of recurrence significantly. In laparoscopic repair, the mesh is placed intraperitoneally. Accordingly, the close contact between mesh and viscera involves a risk of adhesion formation. In this experimental study, we examined the degree of de novo adhesion formation over time to currently available meshes. METHODS: Sixteen sheep each received laparoscopic placement of four (10 x 10 cm) meshes on intact peritoneum...

INTRODUCTION: In recent years, laparoscopic repair of abdominal wall hernias has become increasingly established in routine clinical practice thanks to the myriad advantages it confers. Apart from the risk of intestinal damage following adhesiolysis, to date no information is available on the best way of preventing the formation of new adhesions in the vicinity of the implanted meshes. Numerous experimental investigations, mainly conducted on an open small-animal model, have demonstrated the advantages of coating meshes, inter alia with absorbable materials, compared with uncoated polypropylene meshes...
