Multi-Center Study To Examine The Use Of Flex HD® And Strattice In The Repair Of Large Abdominal Wall Hernias

2014-10-16 19:33:17 | BioPortfolio

Summary

The primary objective of this study is to examine and compare the outcomes associated with the use of Flex HD®, a human acellular dermal matrix (HADM), and Strattice™, a porcine acellular dermal matrix, (PADM) when used as a reinforcing material in the repair of large complicated abdominal wall hernias.

Description

At least 100,000 ventral hernia repairs are performed in the U.S. each year. Recently, biologically-based implants derived from acellular human dermis, porcine small intestinal submucosa, and porcine dermis have been reported in a variety of complex abdominal wall repair procedures. A variety of surgical techniques and implant placement methods have been described, with no one standard technique achieving precedence. Biologic implant reinforcement of a myofascial closure by means of component separation, or at a minimum, where three-layer fascial approximation is not possible, sublay placement (i.e., closure of the posterior rectus sheath under the implant) are described strategies. These techniques allow placement of the implant against an intact fascial layer and may improve implant incorporation into host tissue. However, the current literature shows few, if any, prospective, randomized, head-to-head comparisons of human acellular dermal matrix (HADM) allograft and porcine acellular dermal matrix (PADM) xenograft when used as a reinforcing material in the repair of large abdominal hernias by a component separation technique.

The Musculoskeletal Transplant Foundation (MTF) has manufactured and processed Flex HD Acellular Hydrated Dermis. This acellular dermis is derived from human skin. In complicated ventral hernia repairs, this type of graft tissue is necessary. Flex HD has been shown to reduce operative time, lower operative costs and provides minimal elasticity.

The primary objective of this study is to examine and compare the outcomes associated with the use of Flex HD®, a human acellular dermal matrix (HADM), and Strattice™, a porcine acellular dermal matrix, (PADM) when used as a reinforcing material in the repair of large complicated abdominal wall hernias.

Medical and Biotech [MESH] Definitions

A protrusion of abdominal structures through the retaining ABDOMINAL WALL. It involves two parts: an opening in the abdominal wall, and a hernia sac consisting of PERITONEUM and abdominal contents. Abdominal hernias include groin hernia (HERNIA, FEMORAL; HERNIA, INGUINAL) and VENTRAL HERNIA.

A hernia caused by weakness of the anterior ABDOMINAL WALL due to midline defects, previous incisions, or increased intra-abdominal pressure. Ventral hernias include UMBILICAL HERNIA, incisional, epigastric, and spigelian hernias.

A groin hernia occurring inferior to the inguinal ligament and medial to the FEMORAL VEIN and FEMORAL ARTERY. The femoral hernia sac has a small neck but may enlarge considerably when it enters the subcutaneous tissue of the thigh. It is caused by defects in the ABDOMINAL WALL.

Protrusion of tissue, structure, or part of an organ through the muscular tissue or the membrane by which it is normally contained. Hernia may involve tissues such as the ABDOMINAL WALL or the respiratory DIAPHRAGM. Hernias may be internal, external, congenital, or acquired.

An abdominal hernia with an external bulge in the GROIN region. It can be classified by the location of herniation. Indirect inguinal hernias occur through the internal inguinal ring. Direct inguinal hernias occur through defects in the ABDOMINAL WALL (transversalis fascia) in Hesselbach's triangle. The former type is commonly seen in children and young adults; the latter in adults.
