Evaluating a new treatment for hemorrhoids using artery embolization

A Randomized Comparative Evaluation of Superior Rectal Arterial Embolization in Hemorrhoidal Disease

Not applicable Interventional Universitair Ziekenhuis Brussel · NCT05697562

This study is testing a new, less invasive treatment for hemorrhoids called artery embolization to see if it works as well as current methods for reducing bleeding and symptoms in adults with hemorrhoids.

What this trial studies

This clinical trial investigates the effectiveness and safety of Superior Rectal Artery Embolization (SRAE) as a minimally invasive treatment for hemorrhoidal disease (HD) characterized by significant rectal bleeding. The study aims to compare SRAE with established treatments like Rubber Band Ligation (RBL) and Doppler-Guided Hemorrhoidal Artery Ligation (DG-HAL) to determine if SRAE is equally effective in controlling symptoms and bleeding. Participants will include adults with grades I-III hemorrhoids, and the trial will assess the feasibility of SRAE while ensuring no damage to the sphincter or mucosal tissue occurs. The results will help define the therapeutic role of SRAE in managing HD.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with grades I-III hemorrhoids experiencing significant rectal bleeding.

Not a fit: Patients with permanent hemorrhoidal prolapse, rectal prolapse, or a history of proctological surgery for hemorrhoids may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a safer and less invasive option for patients suffering from hemorrhoidal disease.

How similar studies have performed: Previous studies have shown promising results for SRAE, but this trial aims to confirm its efficacy in a randomized controlled setting.
