Meshes for Intraabdominal Placement (Laparoscopic) V.- MESHES FOR INTRAABDOMINAL PLACEMENT (LAPAROSCOPIC) PICTURES NAME of the products Soft Tissue Patch MANUFACTURER Gore DESCRIPTION e-PTFE mesh for intraperitoneal placement For reconstruction of hernias or soft tissue deficiencies, surgeons require a prosthesis affording a secure repair with decreased risk of recurrence, increased patient comfort postoperatively, and minimal complications such as adhesions and fistula formation. The GORE-TEX® Soft Tissue Patch has long been the prosthetic patch of choice for soft tissue repairs. Composed of the inert biomaterial expanded polytetrafluoroethylene (ePTFE), it features a microporous structure allowing for host tissue incorporation. GORE-TEX® Soft Tissue Patch meets the unique challenges of laparoscopic hernia repair and inguinal herniorrhaphy, as well as temporary bridging of fascial defects. It is contraindicated for the reconstruction of cardiovascular and orthopedic defects. The GORE-TEX® Soft Tissue Patch has material and suture/staple retention strength greater than the most commonly used meshes. The biological inertness of the prosthesis, combined with softness and conformability in vivo, minimizes foreign-body response, erosion into the bowel, and adhesions to surrounding viscera. The GORE-TEX® Soft Tissue Patch offers ease of handling, including cutting and shaping to size without fraying. Pre-configured patches requiring little or no trimming before implantation are also provided.

It is a film of condensed polytetrafluoroethylene (cPTFE) with very low density (0.9 g/cm3) and a macroporous star-shaped structure (2.4 mm). Omyra® Mesh is the first mesh in a monolayer, non-coated format which has antiadhesive and bacterial resistant properties. The cPTFE material improves the adhesion prevention features of the traditional expanded PTFE, whereas the star-macroporous structures enhance a fast tissue integration like the one achieved with polypropylene meshes. Furthermore, the transparent monolayer that Omyra® Mesh provides, offers excellent handling, especially in laparoscopic procedures. ADVANTAGES • Highly biocompatible with star pore structures • Macropores to allow an excellent tissue integration • Fast neo-peritoneum formation covering the mesh • Impairment of bacterial growth • Reduction of adhesion formation • Condensed PTFE • Transparent and tailorable ensuring an optimal handling • http://www.bbraun.com/cps/rde/xchg/bbraun- com/hs.xsl/9094.html PICTURES NAME of the products COMPOSIX™ EX Mesh MANUFACTURER Bard, Davol DESCRIPTION Heavy-weight polypropylene/ePTFE composite for laparoscopic repair of ventral and incisional hernias ADVANTAGES • Two distinctly different sides: Polypropylene BARD® Mesh on one side to promote tissue ingrowth and sub-micronic ePTFE on the other side to minimize adhesions to the prosthesis. • Elliptically shaped design: Reduces the need to trim the mesh, saving time. • Low Profile: Makes it ideally suited for laparoscopic ventral hernia repairs. • Sealed Edge: Prevents exposure of the polypropylene mesh side from contact with the bowel, thus potentially reducing the chances of adhesions around the edge of the prosthesis. http://www.davol.com/products/soft-tissue- reconstruction/hernia-repair/ventral-hernia- repair/laparoscopic-repair-options/composix- ex-mesh/ PICTURES NAME of the products COMPOSIX™ L/P Mesh MANUFACTURER Bard, Davol DESCRIPTION Light-weight, low profile polypropylene BARD® Soft Mesh specifically designed to meet the meticulous challenges of laparoscopic ventral hernia repair ADVANTAGES Made with lightweight, low profile • polypropylene BARD® Soft Mesh that is approximately 60% lighter than traditional polypropylene mesh. • Lightweight, large pore polypropylene matrix leaves less foreign body mass than traditional polypropylene mesh. • Easier handling and laparoscopic insertion – all sizes can fit through a trocar. • Optional Introducer Tool, which is packaged with larger sizes, makes insertion even easier. • Two distinctly different sides: polypropylene BARD® Soft Mesh on one side to promote tissue ingrowth and sub-micronic ePTFE on the other side to minimize tissue attachment to the prosthesis. • http://www.davol.com/products/soft-tissue- reconstruction/hernia-repair/ventral-hernia- repair/laparoscopic-repair-options/composix-lp- mesh/ PICTURES NAME of the products SEPRAMESH™ IP Composite MANUFACTURER Bard, Davol DESCRIPTION Davol is excited to offer an innovative mesh combined with a proven absorbable barrier to minimize tissue attachment to the mesh.The absorbable layer is built on a foundation of proven Sepra* technology, supported by 11 years of clinically demonstrated success.

    Clinical Research and Trials ` Research Article ISSN: 2059-0377 Regenerative surgery for inguinal hernia repair Valerio Di Nicola1,2* and Mauro Di Pietrantonio3 1West Sussex Hospitals NHS Foundation Trust, Worthing Hospital, BN112DH, UK 2Regenerative Surgery Unit, Villa Aurora Hospital-Foligno, Italy 3Clinic of Regenerative Surgery, Rome, Italy Abstract Inguinal hernia repair is the most frequently performed operation in General Surgery. Complications such as chronic inguinal pain (12%) and recurrence rate (11%) significantly influence the surgical results. The 4 main impacting factors affecting hernia repair results are: mesh material and integration biology; mesh fixation; tissue healing and regeneration and, the surgical technique. All these factors have been analysed in this article. Then a new procedure, L-PRF-Open Mesh Repair, has been introduced with the aim of improving both short and long term results. We are presenting in a case report the feasibility of the technique. Introduction Only 57% of all inguinal hernia recurrences occurred within 10 years after the hernia operation. Some of the remaining 43% of all Statistics show that the most common hernia site is inguinal (70- recurrences happened only much later, even after more than 50 years [7]. 75% cases) [1]. A further complication after inguinal hernia repair is chronic groin Hernia symptoms include local discomfort, numbness and pain pain lasting more than 3 months, occurring in 10-12% of all patients. which, sometimes can be severe and worsen during bowel straining, Approximately 1-6% of patients have severe chronic pain with long- urination and heavy lifting [2]. Occasionally, complications such as term disability, thus requiring treatment [5,8].

  • Surgical Mesh Repair of Inguinal Hernia in Men
    Plain Language Summary January 2020 Surgical mesh repair of inguinal hernia in men What is an inguinal hernia? An inguinal hernia is a type of groin hernia. Inguinal hernias occur when a piece of bowel or fatty tissue bulges out through the abdominal wall causing a swelling in the groin. Inguinal hernias are much more common in men than women: nine hernias in men to every one hernia in women. What is surgical mesh hernia repair? Operations to repair an inguinal hernia can either use a piece of surgical mesh to reinforce the body tissues or surgical stitches to pull the body’s tissues together. Surgical mesh is a loosely woven sheet of polypropylene (a type of plastic). The ‘thread’ used to stitch tissues together for hernia repair is also made of polypropylene. Why is this important? Use of surgical mesh has become an important topic in the last few years following women’s experiences of severe chronic pain after an operation using surgical mesh to treat pelvic organ prolapse. In Scotland there are around 5,000 inguinal hernia repairs each year that use surgical mesh. Following the issues raised about surgical mesh for pelvic organ prolapse, there is an awareness that similar issues need to be considered in relation to using surgical mesh for repair of inguinal hernias. What we did We assessed whether inguinal hernia repair using surgical mesh was effective, safe and good value for money. We also explored patient experiences and views about using surgical mesh for inguinal hernia repair. What we found Men who had an inguinal hernia repaired using surgical mesh were less likely to have their hernia return compared with men who had their hernia repaired using surgical stitches.

Due to the large number of hernial relapses and other complications, such as infections, adhesion to the intestines, or the formation of adhesions, the treatment of hernias is still a surgical challenge. The current standard for the preventive and causal treatment of parastomal hernias is to perform a procedure with the use of a mesh implant. Researchers are currently focusing on the analysis of many relevant options, including the type of mesh (synthetic, composite, or biological), the available surgical techniques (Sugarbaker’s, “keyhole”, or “sandwich”), the surgical approach used (open or laparoscopic), and the implant position (onlay, sublay, or intraperitoneal onlay mesh). Current surface modification methods and combinations of different materials are actively explored areas for the creation of biocompatible mesh implants with different properties on the visceral and parietal peritoneal side. It has been shown that placing the implant in the sublay and intraperitoneal onlay mesh positions and the use of a specially developed implant with a 3D structure are associated with a lower frequency of recurrences.

Any advance in this topic translates to an improved quality of life for recipient patients. One application of a biomaterial is the repair of an abdominal wall defect whether congenital or acquired. In the great majority of cases requiring surgery, the defect takes the form of a hernia. Over the past few years, biomaterials designed with this purpose in mind have been gradually evolving in parallel with new developments in the different surgical techniques. In consequence, the classic polymer prosthetic materials have been the starting point for structural modifications or new prototypes that have always strived to accommodate patients’ needs.

KRAUSE,1 Stuart J. GALLOWAY,2 Soo K. KHOO,3 Richard LOURIE2 and Judith T. W. GOH1 1Urogynaecology Unit, Gold Coast Hospital, Southport, 2Department of Anatomical Pathology, St Vincent’s Hospital, Melbourne, and 3Department of Gynaecology, Royal Brisbane Women’s Hospital, Brisbane, Australia Abstract Aim: To study the biocompatibility of surgical meshes for use in pelvic reconstructive surgery using an animal model. Methods: Eight different types of mesh: Atrium, Dexon, Gynemesh, IVS tape, Prolene, SPARC tape, TVT tape and Vypro II, were implanted into the abdominal walls of rats for 3 months’ duration. Explanted meshes were assessed, using light microscopy, for parameters of rejection and incorporation. Results: Type 1 (Atrium, Gynemesh, Prolene, SPARC and TVT) and type 3 (Vypro II, Dexon and IVS) meshes demonstrated different biocompatible properties. Inflammatory cellular response and fibrosis at the interface of mesh and host tissue was most marked with Vypro II and IVS. All type 1 meshes displayed similar cellular responses despite markedly different mesh architecture. Conclusions: The inflammatory response and fibrous reaction in the non-absorbable type 3 meshes tested (IVS and Vypro II) was more marked than the type 1 meshes. The increased inflammatory and fibrotic response may be because of the multifilamentous polypropylene components of these meshes. Material and filament composition of mesh is the main factor in determining cellular response. Key words: animal model, biocompatibility, monofilament, multifilament, surgical mesh.

  • Hernia Repair
    HERNIA REPAIR What is a Hernia? A hernia is a weakness or tear in the wall of the abdomen resulting in a bulge or tear. The inner lining of the abdomen pushes through the weakened area of the abdominal wall to form a small balloon-like sax. This can allow a loop of intestine or abdominal tissue to push into the sac. A hernia can cause severe pain and potentially serious problems that could require emergency surgery. Hernias may be acquired (caused by wear and tear over the years) or congenital (result from a weakness in the abdominal wall present since birth). Hernias can get worse and grow larger over time. A hernia does not go away over time, nor will it go away by itself. Men, women and children of all ages can have hernias. How do I know I have a hernia? • Common areas to develop a hernia are in the groin (inguinal), belly button (umbilical), the site of a previous operation (incisional), high in the thigh, just below the groin (femoral), and in the groin at the internal ring (indirect inguinal hernia). • Hernias can be on both sides of the groin (bilateral hernias) or may recur at the site of a previous hernia (recurrent hernia). • You may notice a bulge under the skin or feel pain when you lift heavy objects, cough, or strain during urination or bowel movements. You may notice pain during prolonged sitting or standing. • The pain can be sharp and sudden or a dull ache that worsens towards the end of the day.
