Is this trial a fit for you?

Likely a good fit

Ideal candidates are women scheduled for hysterectomy or adnexal surgery who have normal vaginal examinations and are being considered for the vNOTES approach.

Probably not a fit

Patients with a history of pelvic radiation, malignancy, or those undergoing concurrent vaginal operations for prolapse or urinary issues may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of trans-vaginal ultrasound in selecting appropriate candidates for Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES). The research aims to determine if pre-operative imaging can enhance patient selection, particularly for women with a history of pelvic inflammatory disease or endometriosis. By comparing ultrasound evaluations with surgical outcomes, the study seeks to improve the safety and efficacy of vNOTES procedures. This approach addresses the need for better guidelines in the rapidly evolving field of minimally invasive surgery.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective surgical options for women undergoing gynecologic procedures.

How similar studies have gone: While the vNOTES technique has shown promise in previous studies, this specific approach using ultrasound for patient selection is novel and has not been extensively tested.
