Fertility outcome after treatment of retained products of conception : a systematic review

Journal Contribution - Review Article

Background: Treatment of retained products of conception (RPOC) can be expectant, medical or operative. Surgical removal of RPOC may lead to intrauterine adhesions (IUA) and Asherman's syndrome. Objective: To evaluate how treatment options for RPOC affect future fertility by means of a systematic review. Search strategy: MEDLINE, EMBASE, The Cochrane Library, and clinical trial registers were searched, and reference lists were scanned. Selection criteria: Randomised controlled trials (RCT) comparing different treatment options for RPOC (conservative, medical or surgical treatment, including curettage and/or hysteroscopic techniques, with or without application of anti-adhesion therapy), in women of reproductive age, were eligible for inclusion. Data collection and analysis: Reviewers independently performed data extraction and quality of evidence assessment. For dichotomous variables, results were presented as risk ratio (RR) with 95% CI. Main results: Two studies were included. Nonsignificant differences were observed between the use of an anti-adhesion barrier gel versus no treatment after operative hysteroscopy in IUAs (RR 0.32, 95% CI 0.04 to 2.80, P value = 0.30) and clinical pregnancy (RR 2.22, 95% CI 0.67 to 7.42, P value = 0.19), and between hysteroscopic morcellation versus loop resection in IUAs (RR 0.86, 95% CI 0.06 to 13.12, P value = 0.91). Conclusion: There is insufficient evidence on how different treatment options for RPOC affect future reproductive outcomes. Results from ongoing RCTs are needed to guide clinicians towards choosing the best treatment.
