Hemorrhoidal Artery Embolization: Longitudinal Impact On Symptoms (HELIOS)
- Conditions
- Internal HemorrhoidsHAE
- Registration Number
- NCT07179601
- Lead Sponsor
- University of California, Los Angeles
- Brief Summary
Hemorrhoidal artery embolization (HAE) is a novel treatment for symptomatic internal hemorrhoids. HAE involves the deliberate blockage (embolization) of enlarged rectal or hemorrhoidal arteries leading to reduction of abnormal blood flow to the hemorrhoidal tissue. The aim of HAE is to the improve hemorrhoid related symptoms, especially bleeding. Initial reports of HAE have demonstrated that it both safe and effective. Following an initial clinic visit to determine trial candidacy, enrolled patients will be subsequently treated with HAE. Patients will be followed for a year with clinic follow-up visits at 1, 3, 6 and 12 months.
- Detailed Description
Hemorrhoidal artery embolization (HAE) is a novel treatment for symptomatic internal hemorrhoids. HAE involves the deliberate blockage (embolization) of enlarged rectal or hemorrhoidal arteries leading to reduction of abnormal blood flow to the hemorrhoidal tissue. The aim of HAE is to the improve hemorrhoid related symptoms, especially bleeding. Initial reports of HAE have demonstrated that it both safe and effective. However, the initial data is limited due to variations in embolization techniques, few studies with prospective long-term follow-up, and studies focusing on patients with only severe symptoms. Further research is needed to understand the specific long-term effectiveness of different embolization materials in a population that more accurately reflects the large number of patients with hemorrhoidal disease who would likely benefit from HAE. The proposed research project includes 22 patients with symptomatic internal hemorrhoids. Following an initial clinic visit to determine trial candidacy, enrolled patients will be subsequently treated with HAE. Patients will be followed for a year with clinic follow-up visits at 1, 3, 6 and 12 months.

Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- SINGLE_GROUP
- Primary Outcome Measures
Name Time Method Proportion of patients with decrease in bleeding related symptoms of internal hemorrhoids as defined as a two-point decrease in French Bleeding Score From baseline to 12 months post procedure
- Secondary Outcome Measures
Name Time Method Proportion of technically successful HAE procedures From baseline to 12 months post procedure Change in non-bleeding related symptoms of internal hemorrhoids as measured by the Hemorrhoid Disease Symptom Score (HDSS) From baseline to 12 months post procedure Change in non-bleeding related symptoms of internal hemorrhoids as measured by the Short Health Scale-Hemorrhoidal Disease (SHSHD) From baseline to 12 months post procedure Change in pain related to internal hemorrhoids as measured by the Short Health Scale-Hemorrhoidal Disease (SHSHD), Visual Analog Scale (VAS) From baseline to 12 months post procedure Change in concomitant hemorrhoid medical therapy From baseline to 12 months post procedure Level of patient satisfaction after HAE as determined by four point patient satisfaction questionnaire From baseline to 12 months post procedure Proportion of patients requiring subsequent non-surgical internal hemorrhoid procedures From baseline to 12 months post procedure Proportion of patients requiring surgical management of their internal hemorrhoids From baseline to 12 months post procedure
