Abstract:

BACKGROUND: Understanding the type, biological and material science characteristics of the patch, as well as the feasibility, effectiveness and complications in the application process, can lay the theoretical foundation for the work.
OBJECTIVE: To summarize patch types, characteristics of biology and materials science, to define the feasibility of applying patch in the pelvic floor reconstruction, and to control the complications in the pelvic floor repair and reconstruction.
METHODS: PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net / index.htm) were searched on computer by using Chinese keywords of patch, pelvic floor reconstruction and English keywords of biological Patch, reconstructive pelvic surgery. Articles related to patch type, materials science characteristics and its application effect were included. In the same field, literatures published recently or published in the authority magazine were preferred. According to inclusive criteria, 28 literatures were used.
RESULTS AND CONCLUSION: As the pelvic floor tissue substitute, materials used for pelvic floor repair and reconstruction can replace the damaged pelvic fascia tissue, currently including biological materials and synthetic materials. Various repair materials have their advantages and disadvantages. There has always been controversy regarding patch material choice. Comprehensive literature shows some medical institutions applied the patch for treatment of vaginal anterior and posterior wall prolapse, pelvic organ prolapse, stress urinary incontinence and other pelvic floor dysfunction to varying degrees, the included patients ranged from 1 to 80 cases, the application of patch was showns to be feasible and effective from the operation time, patch placing time, blood loss, hospital stay, postoperative recovery, repair success rate, postoperative residual urine volume and other indicators, it reduces the recurrence rate and reconstructs the pelvic floor function. The most common complications of the patch are the erosion and infection. Specific conditions of the patients should be considered in choosing a suitable surgical approach. But which kind of patch contributes to the proximal application and betters long-term effect of surgery needs to a large-scale prospective case-control study based on a longer time of follow up.
