Long-term outcomes of HAL Doppler or HAL-RAR treatment for hemorrhoids

Recurrence Rate of Hemorrhoidal Disease at 10 Years and More After Hemorrhoidal Artery Ligation (HAL)

Observational University Hospital, Grenoble · NCT04731064

This study looks at how well HAL Doppler and HAL-RAR treatments for hemorrhoids work over the long term by checking if patients have any recurrence of their symptoms at least 10 years after their treatment.

What this trial studies

This observational study evaluates the recurrence rate of hemorrhoidal disease in patients who have undergone HAL Doppler or HAL-RAR interventions at least 10 years prior. The HAL technique involves the ligation of hemorrhoidal arteries and recto-anal repair to address both vascular and mechanical aspects of the condition. Patients are treated under various anesthesia options, often on an outpatient basis, following rectal preparation. The study aims to gather long-term data on the effectiveness of these treatments in preventing recurrence.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and over who have undergone treatment for hemorrhoidal disease at least 10 years ago.

Not a fit: Patients who are minors or those who oppose participation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness of HAL Doppler and HAL-RAR treatments for hemorrhoidal disease.

How similar studies have performed: While the HAL technique has been used in various countries, this study specifically focuses on long-term outcomes, making it a novel approach in assessing recurrence rates.
