Hemorrhoidal Artery Embolization for Hemorrhoids

(HELIOS Trial)

This trial tests a new treatment called hemorrhoidal artery embolization (HAE) for individuals with troublesome internal hemorrhoids. The treatment reduces blood flow to the hemorrhoids by blocking certain blood vessels, potentially alleviating symptoms like bleeding. The study will evaluate the safety and effectiveness of HAE over a year, with check-ups at several intervals. Suitable candidates have had bleeding hemorrhoids confirmed by a doctor and are not interested in surgery or other common treatments. As an unphased trial, this study offers patients the chance to explore a novel treatment option that may relieve symptoms without surgery.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Research has shown that hemorrhoidal artery embolization (HAE) safely treats internal hemorrhoids. Studies have found that HAE effectively reduces hemorrhoid symptoms, particularly bleeding. In one study, 93% of patients felt better just one month after the procedure. Another report highlights that HAE is minimally invasive, requiring no large incisions or extended recovery time. This makes it a suitable option, especially for those who haven't found relief from other treatments. Overall, patients have well-received HAE, and it offers a promising way to manage hemorrhoid symptoms.¹²³⁴⁵

Hemorrhoidal artery embolization (HAE) is unique because it offers a minimally invasive alternative to traditional hemorrhoid treatments like rubber band ligation, sclerotherapy, and hemorrhoidectomy. Unlike these standard options, which often involve direct intervention at the site of the hemorrhoids, HAE works by blocking the blood flow to the hemorrhoidal arteries, reducing swelling and discomfort from the inside out. Researchers are excited about HAE because it has the potential to provide relief with less pain and a quicker recovery time, making it an attractive option for patients seeking a less invasive solution.

Research shows that hemorrhoidal artery embolization (HAE), the treatment under study in this trial, effectively treats bleeding hemorrhoids. Studies have found that it successfully reduces symptoms like bleeding and pain by cutting off blood flow to the affected areas. In clinical trials, HAE achieved technical success in 93-100% of cases and provided symptom relief in 63-94% of patients. This procedure is considered safe, with no serious complications reported. Overall, HAE offers a promising option for those seeking relief from internal hemorrhoids.¹³⁵⁶⁷
