RESUMO
BACKGROUND: Various surgical techniques have been devised for the surgical cosmetic enhancement of female outer genitalia. The selection of an optimal method should be based on satisfaction rates and safety; however, a comprehensive, contemporary systematic assessment of these factors in has been limited in the literature. OBJECTIVES: Our aim was to conduct a comprehensive systematic review and meta-analysis to evaluate the overall satisfaction rates and risk factors associated with various labiaplasty techniques and tools. METHODS: The authors performed a systematic literature search in three medical databases: PubMed, Elsevier and Cochrane Library (CENTRAL) with the closing date of October 2023. Original articles with quantitative satisfaction rates and frequencies of most common complications (hematoma, dehiscence, swelling, bleeding and infection) were included. RESULTS: Systematic search provided a total of 3954 records. After selection and review of the articles, 86 eligible, peer-reviewed studies were identified, of which 53 provided quantitative data. High overall satisfaction rate was found for all methods (Prop: 94%; CI: 93-95%), with highest satisfaction for deepithelization (Prop: 97%; CI: 85%-99%). Complications were generally rare, with elevated incidences for some techniques (wedge resection - dehiscence: Prop: 8%; CI: 5%-13% and composite reduction - swelling: Prop: 13%; CI: 2%-54%). Scalpel has significantly higher incidence of complications than laser, namely for bleeding, swelling and hematoma. CONCLUSIONS: Labiaplasty can be considered a generally effective approach to outer female genitalia beautification, with low associated risks. Surgeons must tailor their approach to the patients' needs and anatomy to achieve maximal satisfaction, given the differences in the frequency of complications for each method.
RESUMO
Polycystic ovary syndrome is a common endocrine disorder, characterized by hyperandrogenism and/or chronic oligo/anovulation, which leads to infertility. The aim of this systematic review and meta-analysis was to explore the efficacy of letrozole compared with clomiphene citrate for ovulation induction in women with polycystic ovarian syndrome. The study protocol has been registered with PROSPERO (registration number CRD42022376611). The literature search included randomized clinical trials. We conducted our systematic literature search across three medical databases: MEDLINE (via PubMed), Cochrane Library (CENTRAL), and Embase. The data synthesis employed a random effects model. Out of the 1994 articles screened, 25 studies fulfilled the inclusion criteria. The letrozole group exhibited a significant increase in endometrial thickness (mean difference = 1.70, confidence interval: 0.55-2.86; I2 = 97%, p-value = 0.008). The odds of ovulation (odds ratio = 1.8, confidence interval: 1.21-2.69; I2 = 51%, p-value = 0.010) and pregnancy (odds ratio = 1.96, confidence interval: 1.37-2.81; I2 = 32%, p-value = 0.002) were significantly higher. The resistance index of the subendometrial arteries showed a significant decrease (mean difference = -0.15, confidence interval: -0.27 to -0.04; I2 = 92%, p-value = 0.030). Women diagnosed with polycystic ovarian syndrome and treated with letrozole for ovulation induction had increased ovulation and pregnancy rates and increased endometrial thickness. The lower resistance index of subendometrial arteries can enhance intrauterine circulation, creating more favorable conditions for embryo implantation and development.
