Deinfibulation for improving obstetric, neonatal, gynecologic, and sexual health outcomes in women and girls with type <scp>III</scp> female genital mutilation: A systematic review and meta‐analysis

Abstract

BACKGROUND: Type III female genital mutilation (FGM) is corrected by the scar tissue removal of the vaginal opening, known as deinfibulation. OBJECTIVES: To determine the current evidence on whether deinfibulation leads to improved obstetric, neonatal, gynecologic, and sexual health outcomes. SEARCH STRATEGY: The following databases were searched from inception to May 18, 2023: CINAHL Plus (EBSCOhost), MEDLINE (Ovid), PsycINFO (EBSCOhost), SCOPUS, and Web of Science. SELECTION CRITERIA: Two review authors independently screened the titles and abstracts, extracted data, and performed the risk of bias assessment. DATA COLLECTION AND ANALYSIS: Meta-analysis was conducted with RevMan, and the quality of evidence was assessed using the GRADE approach. MAIN RESULTS: Eight studies with serious risk of bias involving 3166 women were included. Very low-certainty evidence indicates that deinfibulation for women with type III FGM reduced the odds of an emergency cesarean birth (odds ratio [OR] 0.16, 95% confidence interval [CI] 0.06-0.42) and genital tract lacerations (OR 0.48, 95% CI 0.29-0.79) when compared to women with type III FGM without deinfibulation. Reduced odds of an emergency cesarean birth apply when compared to women without FGM (OR 0.59, 95% CI 0.37-0.93). Antepartum deinfibulation, compared to intrapartum deinfibulation, may lead to a reduction in the duration of labor, with little or no difference in the risk of prolonged labor (low-certainty evidence). Antepartum deinfibulation may increase the likelihood of postpartum hemorrhage and cesarean births in pregnant women with type III FGM (low-certainty evidence). We found no studies for inclusion on gynecologic, urologic, and sexual health outcomes for this update. CONCLUSIONS: The evidence of deinfibulation for women with type III FGM is available only for obstetrics outcomes. Larger observational studies in settings where type III FGM is predominantly practiced are required to improve the certainty of the evidence in these findings.
