Overview
This study aims to evaluate the effects of therapy with implantable Gestrinone compared to oral Dienogest in relieving complaints related to endometriosis.
Description
Patient recruitment will be carried out on a prospective basis and based on the group of patients from the private Medical Clinics in 4 cities (Campina Grande - Pb, São Paulo - SP, São José dos Campos - SP and Brasilia-DF). The study will include 70 adult female patients of menstrual age, pre-menopause (18 to 45 years old), who seek medical treatment to alleviate complaints related to endometriosis. The selected patients will be randomly allocated into two groups, in a 1:1 ratio. Control Group (n=35) - treatment with oral Dienogest - and Test Group (n=35) - Implantation of Gestrinone pellets. Follow-up visits will be scheduled after 1 week and 1, 3, 6, 9 and 12 months of initiation of therapy. Therapies will be compared with respect to the effects on the severity of dysmenorrhea, dyspareunia and non-cyclical pelvic pain (Verbal Scale and Visual Analogue Scale), level of Uterine Bleeding assessed by PBAC, systemic effects (hormonal, hepatic, lipid profile, cell concentration red, clotting factor - assessed through blood tests), endometriosis lesions, endometrial thickness (transvaginal ultrasound), body composition (bioimpendance test), quality of life (EHP30) and sexual function (female sexual function index ) - FSFI. Data analysis will be carried out using validated statistical software. Chi-square or Fisher&#39;s exact tests will be used to compare qualitative variables, while independent t-tests will be used to compare quantitative variables between the two groups. Analysis of variance with repeated measures will be used to compare the average pain intensity over time. The significance level for all tests will be p<0.05.
