Biocompatibility of patch materials in inguinal herniorrhaphy / 中国组织工程研究

ABSTRACT

A retrieve of Pubmed database and China Journal Full-text Database was conducted to summarize the studies concerning the application of patch biomaterials in the inguinal herniorrhaphy. According to the chemical components and biological characteristics, the materials for the repair comprise unabsorbable materials, absorbable materials, composite materials and biological materials. Present research of patch materials focuses on the polypropylene polyester and expandable polytetrafluoroethylene. Patch implant is a kind of long-term chronic stimulation to the host. Local inflammation and continuous reaction severity can be affected by the type, quantity and surface area of the implants, together with the patch structure. Herniorrhaphy materials are doomed to develop towards a biomaterials with minimal invasion, light weight, absorption, easy operation, comfort and few complications. The patching method and material should be varying according to the disease type.
