The hernia repair is a surgical procedure in the world’s most commonly performed. In fact, there are more than 600,000 surgeries to repair hernias performed annually in the United States alone. A hernia is a weakness or defect in the abdominal muscles which can result in the protrusion of tissue through an opening in the outer layers of the abdominal wall. The hernia can develop at any part of the abdominal wall, but generally occur in areas that have a natural tendency to be weak. These areas include the groin (inguinal hernia), the umbilicus (umbilical hernias), hiatus (hiatal hernias) and incisions from previous surgeries (incisional or ventral hernia). While hernias generally do not pose problems in the long-term serious health, they can cause severe pain and discomfort for those suffering from this condition.
Hernias may be present from birth, or may be caused by stress on the abdominal muscles. In either case, hernias do not go away by themselves and the degree of swelling or pain, usually require a surgical procedure to be repaired. Hernia repairs are usually done on an elective basis, which means that the patient and the doctor decide if or when the process should be executed. Emergency procedures are only done for strangulated hernias, which are hernias that have become pinched to the point where the blood supply is cut. These hernias require immediate medical attention because they can become infected and lead to a condition representing a danger to life very quickly.
Hernias are typically repaired by a surgical procedure called herniorrhaphy, in which the surgeon repairs the hole in the abdominal wall by sewing together the surrounding muscle or by placing a patch called “mesh” over the defect. Most surgeons make an incision at the site of the hernia to access the default, although some surgeons prefer to do these procedures laparoscopically.
During a laparoscopic hernia repair, the surgeon makes very small incisions to pass through specialized instruments and an endoscope, a device that allows the surgeon to see the abdominal area without opening the patient up. The Laparoscopic hernia repair has generally results in less postoperative pain and long recovery than open surgery. There remains much controversy over the long term benefits of laparoscopic hernia repair, however, and is not an option for each patient.
The use of surgical mesh to repair hernias is gaining in popularity with surgeons. Most meshes currently on the market are made from synthetic materials such as polypropylene, polyester, silicone or polytetrafluoroethylene (PTFE), commonly known by the brand name of DuPont Teflon ®. While these meshes have good strength characteristics, they remain in the body as implants constant and can sometimes cause adverse reactions when the surrounding tissue identifies these materials as foreign bodies.
To avoid adverse reactions to synthetic materials, some surgeons prefer to use meshes made of biomaterials which are gradually resorbed by the body over time and are then eliminated through biological processes. Since these meshes are not permanent implants, they usually offer only temporary repair of abdominal wall defects and additional surgical procedures are sometimes required to replace the mesh absorbed.
An alternative to synthetic mesh and is absorbable tissue. There are a handful of companies that are now processed human dermis and lyophilized sales for soft tissue repair and growth. This material is implanted using the same technique with other meshes and provides revascularization, cellular ingrowth and the “transform” into the tissue of patients. While this option generally provides a permanent repair fewer adverse reactions, treatment and distribution of human tissue is not resolved by the Administration of Food and Drug Administration (FDA) as well as most other products that are implanted in the human body. In fact, there were a number of recent cases of infections and even deaths resulting from serious implantation of human cadaveric tissue during surgical procedures.
New technologies have recently been developed to solve problems related to the use of synthetic substances, absorbable materials and human tissue in hernia repair procedures. Scientists in Europe have led the research and development of alternatives to these products over the past two decades and have made inroads in major surplus area in the past several years. New ways of gathering and processing natural materials have led to a series of products that offer the strength of synthetic compounds, the biocompatibility of biomaterials and regenerative properties of human tissue.
What materials can offer all the advantages previously mentioned products without corresponding disadvantages? Porcine dermal collagen has an architectural structure very close to human tissue, and thus is readily recognized as friendly by the human body. A leading medical technology company in Europe has developed a patented process by which a sheet of porcine dermis is converted into safe and effective surgical implant for the repair and augmentation of soft tissue. The process, which takes several weeks to complete, remove all materials not collageneous sheet except elastin, and stabilizes the material through a process of cross-linking. The result is a membrane-free cell formation, not reconstituted, non allergenic which has excellent strength characteristics, is completely biocompatible and provides a permanent solution for repairing abdominal wall defects. Because the material itself is a byproduct of the industry, meat packing, it is more readily available than human tissue. In addition, harvesting and processing equipment is strictly regulated by local government, as well as guidelines and international quality standards.
This collagen implant surgery has been used in Europe for these types of procedures for several years and there is strong clinical evidence of safety and efficacy. In fact, the implant was approved for sale in the U.S. by the FDA and there has not been any adverse reaction reported with several thousand locations in Europe. Not only is it safe, since the structure of collagen is so similar to human tissue, once it is implanted the sheet provides the basis for cellular ingrowth and revascularization. This results in an ongoing challenge even the most difficult cases. In addition to positive clinical outcomes, surgeons like the fact they do not need to change their surgical technique for using this product. They can use the same exact same steps they would use for synthetic or absorbable surgical mesh in both open and laparoscopic procedures.
Only physicians can properly diagnose and appropriately treat hernias. However, patients have the right to participate actively in decisions that affect their health or quality of life. Information about the various treatment options are tin game currently available through major part in the discussions between patients and their physicians regarding the best surgical treatment option for them.
