Speech Title: Pseudocapsule Thickness in Reproductive Surgery: A Further Possible Correlation Between Submucous Fibroids And Fertility
Abstract: Uterine fibroid, during its growth, cause the progressive formation of a peripheral anatomical structure, a pseudocapsule. This structure originates fromthe fibroid compression of the surrounding myometrium and separates fibroid from the healthy myometrium. The pseudocapsule shifts the myometrial muscular fibers, maintaining the integrity and contractility of uterine musculature. Fibroid is structurally anchored to its pseudocapsule by connective bridges, but it lacks its own true vascular pedicle. Occasionally, bridges of collagen fibers and vessels anchoringfibroid to myometrium interrupting the pseudocapsule surface. Those physio pathological phenomena result in the formation of a clear cleavage plane either between myoma and the pseudocapsule, or between the pseudocapsule and the surrounding myometrium, as well. At the ultrastructural level, visualized by transmission electron microscopy (TEM), the pseudocapsule cells have the features of smooth muscle cells like the myometrium, indicating that the pseudocapsule is part of the myometrium compressed by the myoma. Moreover, pseudocapsule is plentiful of collagen fibers, neurofibers and blood vessels, as a neurovascular bundle surrounding fibroid. Genetically, the pseudocapsule of the myoma has the same biological structure as the myometrium and the biochemical growth factors evaluation showed intense angiogenesis in pseudocapsule vessels. Angiogenetic factorsidentified in the pseudocapsule vessels are already widely involved in the physiology of the myometrium and these substances are thought to have a pivotal role in wound healing and muscular innervation. Myometrial wound healing is an interactive, dynamic process involving neuromodulators, angiogenetic factors, neuropeptides, blood cells, extracellular matrix, and parenchymal cells that follows three complex and overlapping phases: inflammation, tissue formation, and tissue remodeling. In the physiology of these processes, they also fit also nervous system and its neurotransmitters, as Substance P (SP), Vasoactive Intestinal Peptide (VIP), neuropeptide Y (NPY), Oxytocin (OXT), Vasopressin (VP), PGP 9.5, calcitonin gene-related peptide (CGRP), growth hormone-releasing hormone (GHRH). They play a role in mediating inflammation and wound healing, involved in physiology and scar repair in different tissues, including uterine muscle. In regenerative processes associated to pseudocapsule sparing, neuropeptides and neurotransmitters are speculativelyinvolved also in wound healing. Moreover, growth factors present in the myoma pseudocapsule induce angiogenesis peripherally to myometrium. The intracapsular myomectomycan be done bylaparotomic, laparoscopic, robotic, vaginal and hysteroscopicapproach.The surgical benefit is visible during and after myomectomy: the bleeding is reduced, the myometrial anatomyis largely respected, themyometrial healing is preserved and enhanced, as confirmed by clinical and ultrasound investigations on scar site after intracapsular myomectomy.The study of the thickness of the pseudocapsule showed an increase in submucosal fibroids, compared to intramural and subserosal ones. This feature has a further impact on female reproduction to be investigated, as submucosal fibroids have been shown to negatively impact fertility.
