What this trial studies

This study aims to evaluate the effectiveness of heparin solution versus hyaluronic acid barrier gel in preventing intrauterine adhesions following operative hysteroscopy. Patients undergoing this procedure will receive either treatment immediately after surgery, and their outcomes will be assessed through follow-up hysteroscopy 4 to 8 weeks later. The study will measure the incidence and severity of adhesions, as well as any changes in menstrual patterns and fertility over the following year. Data collected will help determine which method is more effective in reducing post-surgical complications.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention of intrauterine adhesions, enhancing recovery and fertility outcomes for patients.

How similar studies have gone: Previous studies have explored similar interventions, but this specific comparison of heparin and barrier gel is novel.
