Myometrium reaction on implantation of polypropylene mesh protheses in experiment

Abstract

The article is devoted to the study of the problem of myometrium reaction on implantation of polypropylene mesh prostheses in uterine suture strengthening. Experimental studies have found in animals after strengthening the seam on the uterus polypropylene mesh implant following complications in the postoperative period, such as: bruises, seroma seam and deformation of the uterus. These complications occurred significantly more often than when suturing the incision of the uterus row of blanket stitch. In the evaluation of adhesions, the statistically significant differences in the studied groups weren´t found. According to morphological studies, it was revealed in the early days a tissue edema and infiltration by plasma cells and macrophages, which remained at a later time, a capsule isn´t fully formed, cellular component prevailed over fiber. In later terms a mature fibrous capsule is formed, necrosis areas are detected on the inner side of prosthesis filaments, giant cells of foreign bodies, neutrophils, eosinophils were found around filaments.
 
 To objective evaluation of the state of inflammatory process around prosthesis filaments the authors used a cellular index method. It was determined that the degree of spatial organization of the capsule and the degree of maturity of the connective tissue is in direct proportion to the duration of the experiment.
