What this trial studies

This clinical trial investigates the effectiveness of auto-cross linked hyaluronic acid gel in preventing the reformation of intrauterine adhesions following hysteroscopic resection of retained products of conception (RPOC). RPOC can lead to complications such as infertility and menstrual abnormalities if not treated properly. The study will randomly assign patients who have undergone the surgical procedure to receive either the gel or standard care, allowing for a comparison of outcomes related to adhesion formation. The goal is to determine if the gel can reduce the risk of complications associated with RPOC treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are women diagnosed with retained products of conception who are undergoing hysteroscopic resection.

Not a fit: Patients with severe complications from surgery or those with active genital tract infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve fertility outcomes for patients who have experienced retained products of conception.

How similar studies have performed: While the use of hyaluronic acid gel in this context is promising, similar studies have shown mixed results, indicating that this approach may still be novel.
