Abstract:

OBJECTIVE: To investigate the application of biological mesh plain patch in the repair of inguinal hernia.
METHODS: A computer search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed by screening “patches, surgery, inguinal hernia" in English and in Chinese as key words in the titles and summaries. Articles related to the material science characteristics, biocompatibility and application effect were included, those published recently or published in the authority journal were preferred in the same field. Totally 25 literatures were involved.
RESULTS: According to chemical compositions and biological characteristics, hernia repair materials can be divided into unabsorbable materials, absorbable materials, composite repair materials and bio-based materials. Unabsorbable materials are predominant in the repair materials, and include metal and nonmetal materials. These materials have good biocompatibility, great tensile strength, strong tolerance, no foreign body sensation after implantation. Tension-free hernia repair patch can stimulate the rapid fibroblast response of surrounding tissues, restore and enhance the tissue strength in repair parts, it is more reasonable and more reliable than all kinds of tension suture repair, which takes the altered anatomical structure of the inguinal canal as the prerequisite, and prevents the anatomical basis of hernia recurrence. Clinical research shows that plain patch has well histocompatibility, no rejection, and certain resistance to infection, it is the ideal material of inguinal hernia repair.
CONCLUSION: Tension-free repair treatment of inguinal hernia using mesh plain patch is a good surgical approach, with surgical safety, low recurrence rate, little trauma, and few complications.
