Heparin Solution Versus Anti-adhesion Barrier Gel for Intrauterine Adhesions Prevention After Operative Hysteroscopy

In this trial the investigators aim to evaluate and compare the effect of heparin solution to anti-adhesive hyaluronic barrier gel administration immediately after operative hysteroscopy on post-surgical complications (incidence, extent and severity of intrauterine adhesions, abnormal menstrual cycle pattern) and fertility. Patients undergoing operative hysteroscopy will be identified and invited to participate in the trial. At 4 to 8 weeks after the initial surgery, a follow-up, diagnostic hysteroscopy will be performed to identify indications for subsequent operative procedure and classify intrauterine adhesions according to extent of uterine cavity affected and type of formation found. Data on subsequent persistent irregular menstrual bleeding and pregnancy success up to 12 months following treatment will also be collected.
