Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are women with histologically confirmed High Grade Squamous Intraepithelial Lesion (HSIL) and a colposcopically visible lesion.
✕Probably not a fit
Patients who are pregnant, taking immunosuppressive drugs, or have other significant health issues may not benefit from this study.

What this trial studies
This study aims to compare the oncological safety of two surgical procedures, LLETZ and LEEP, for the treatment of cervical dysplasia. LLETZ involves the complete resection of the dysplastic lesion along with the transformation zone, while LEEP targets only the visibly affected area. The primary focus is to determine which method has a lower rate of incomplete resection, known as 'non-in-sano rate'. By evaluating these two approaches, the study seeks to optimize surgical therapy for cervical dysplasia and improve patient outcomes.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical techniques that enhance the safety and effectiveness of cervical dysplasia treatment.
How similar studies have gone: While there is limited direct comparison data between LLETZ and LEEP, previous studies on cervical dysplasia treatments have shown varying degrees of success with different surgical methods.
