Prospective HemorrhoIdaL EmboliSation (PILES) Registry (PILES)

June 10, 2026 updated by: Joint & Vascular Institute

Creation Of a Prospective Registry For Hemorrhoid Artery Embolization At The Joint & Vascular Institute

The goal of this observational study (prospective registry) is to collect long-term real-world data on the effectiveness and safety of hemorrhoid artery embolization (HAE) for symptomatic bleeding internal hemorrhoids in adults aged 18 years or older that have not responded to medical therapy.

The main question it aims to answer are:

1) Does HAE lead to sustained improvement in bleeding (HDSS scores over 12-36 months?

Participants will:

Undergo HAE as part of their routine clinical care.
Complete clinical follow-up assessments at 1, 3, 6, 12, 18, 24, and 36 months after treatment, including symptom and quality-of-life questionnaires.
Have safety outcomes tracked according to Society of Interventional Radiology guidelines.

There is no comparison group; results will be analyzed to identify predictors of success and inform best practices for patient selection and treatment.

Study Population

The study population consists of adult patients (18 years and older) presenting to the Joint & Vascular Institute for clinical consultation regarding symptomatic internal hemorrhoids. This population includes individuals who have failed standard medical management (such as dietary modifications, topical therapies, or office-based procedures) and are seeking minimally invasive alternatives to surgical hemorrhoidectomy. The registry will include men and women of all races and ethnicities without exclusion, provided they meet the clinical criteria for Hemorrhoidal Artery Embolization (HAE) as determined by the Principal Investigator or Sub-Investigators.

Description

Inclusion Criteria:

Adults (≥18 years) with symptomatic bleeding internal hemorrhoids refractory to medical therapy, referred for HAE.

Exclusion Criteria:

Pregnancy, coagulopathy, severe comorbidities, or inability to consent.
