Abstract:

OBJECTIVE: To evaluate the clinical application of inguinal hernia repair materials and in vivo histocompatibility after repair, to search for a suitable repair material.
METHODS: Using “inguinal hernia, repair materials, wound healing, clinical, tissue compatibility” in Chinese and in English as the key words, a computer search was performed among articles published from January 2000 to December 2009. Articles about the hernia repair materials and inguinal defects repair were included; duplicated research or Meta analysis articles were eliminated.
RESULTS: The article discussed the type and the nature of hernia repair materials, the reasonability and benefits of preperitoneal repair method. According to chemical composition of materials science and biological characteristics, hernia repair materials can be divided into non-absorbable materials, absorbable materials and composite materials. The advantages of polypropylene mesh, a non-absorbable material, is large mesh, which is conducive to fibrous tissue ingrowth, to improve the tissue strength and tensile resistance, with good resistance to infection; its disadvantage is hard texture, and can not be separately placed in an abdominal cavity. Absorbable materials can be against the infection and promote the proliferation of collagen. Composite materials may reduce the amount of foreign body (polypropylene), prevent adhesion, and have anti-inflammatory effects.
CONCLUSION: The clinical application of hernia repair materials promotes the development of for a variety of tension-free hernia repair. With the emergence of new materials, more patches can be designed according to different physical or biological characteristics of patients.
