A novel bilateral anterior sacrospinous hysteropexy technique for apical pelvic organ prolapse repair via the vaginal route: a cohort study.

BACKGROUND: Uterine-preserving techniques are becoming increasingly popular in the last decade. This investigation evaluates a novel hysteropexy technique using a mesh in sling-alike configuration [Splentis (Promedon, Argentina)] which is attached anteriorly to the cervix and suspended to the sacrospinous ligaments bilaterally via the vaginal route in women undergoing surgery for uterine prolapse. METHODS: This was a single-center cohort study, evaluating women who underwent transvaginal hysteropexy with Splentis for primary uterine descent. Data have been collected prospectively as part of the quality assurance system. Primary endpoint was treatment success, defined as a combined endpoint including the absence of a vaginal bulge symptom and no retreatment of apical prolapse. A validated questionnaire to evaluate quality-of-life and prolapse symptoms was utilized. Descriptive analysis was applied. Wilcoxon signed-rank test was performed to compare paired samples. The significance level was set at 5%. RESULTS: A total of 103 women with a median age of 68.0 [IQR 11.5] years with a median apical POP-Q stage of 3 were included. The median surgery time was 22 [IQR 12] minutes and no intraoperative complication occurred. After a median follow-up time of 17 months, treatment success was achieved in 91 (89.2%) patients and quality of life and patient report outcomes improved significantly (p < 0.001). Mesh exposure occurred in 3 (2.9%) patients. Of these, two patients required surgical revision, and one patient was treated conservatively. One patient required partial mesh removal due to dyspareunia. CONCLUSION: Bilateral sacrospinous hysteropexy with Splentis offers an efficacious and safe alternative for apical compartment repair, incorporating the advantages of pelvic floor reconstruction via the vaginal route.

Pain Mechanisms in Peritoneal Diseases Might Be Partially Regulated by Estrogen.

To identify factors influencing the differential pain pathogenesis in peritoneal endometriosis (pEM) and peritoneal carcinomatosis in ovarian cancer (pOC), we undertook an experimental study. Tissue samples of 18 patients with pEM, 15 patients with pOC, and 15 unaffected peritoneums as controls were collected during laparoscopy or laparotomy. Immunohistochemical stainings were conducted to identify nerve fibers and neurotrophins in the tissue samples. Additionally, 23 pEM fluids, 25 pOC ascites fluids, and 20 peritoneal fluids of patients with myoma uteri as controls were collected. In these fluids, the expression of neurotrophins was evaluated. The effects of peritoneal fluids and ascites on the neurite outgrowth of chicken sensory ganglia were estimated by using a neuronal growth assay. An electrochemiluminescence immunoassay was carried out to determine the expression of estrogen in the peritoneal fluids and ascites. The total and sensory nerve fiber density was significantly higher in pEM than in pOC ( P < .001 and P < .01). All neurotrophins tested were present in tissue and fluid samples of pEM and pOC. Furthermore, the neurotrophic properties of pEM and pOC fluids were demonstrated, leading to sensory nerve fiber outgrowth. Estrogen concentration in the peritoneal fluids of pEM was significantly higher compared to ascites of pOC ( P < .001). The total and sensory nerve fiber density in the tissue samples as well as the estrogen expression in the peritoneal fluid of pEM was considerably higher than that in pOC, representing the most notable difference found in both diseases. This might explain the differential pain perception in pEM and pOC. Therefore, estrogen might be a key factor in influencing the genesis of pain in endometriosis.
