Non-Surgical Hemorrhoid Treatments: Rubber Band Ligation, Sclerotherapy, and Embolization Compared

Non-Surgical Hemorrhoid Treatments: Rubber Band Ligation, Sclerotherapy, and Embolization Compared

Hemorrhoids are one of the most common colorectal conditions in the world, and one of the most under-discussed. The discomfort of rectal bleeding, itching, and prolapse sends millions of people to their doctors each year, yet many patients don’t know that surgery isn’t always the answer. Today, a range of effective non-surgical hemorrhoid treatments can resolve symptoms with minimal downtime, no general anesthesia, and a fraction of the recovery time of traditional hemorrhoidectomy. 

This guide breaks down the three most widely used office- and clinic-based procedures: rubber band ligation (RBL), sclerotherapy, and the newer hemorrhoid artery embolization (HAE), so you can understand how each works, who it suits, and what the evidence says.

What Are Hemorrhoids, and When Do They Need Treatment?

Hemorrhoids are cushions of vascular tissue naturally present in the anal canal. Problems arise when these cushions become enlarged, inflamed, or prolapsed. Internal hemorrhoids (graded I–IV on the Goligher scale) are the most amenable to non-surgical intervention, particularly when bleeding, prolapse, or chronic discomfort is the primary complaint.

Conservative measures like increased dietary fiber, adequate hydration, sitz baths, and topical creams are the first line of defense. But when symptoms persist or recur despite lifestyle changes, office-based procedures are the next step before considering surgery.

Rubber Band Ligation

Rubber band ligation is the most commonly performed in-office procedure for internal hemorrhoids, and for good reason — it is straightforward, fast, and backed by decades of clinical data.

How it works: A small elastic band is placed around the base of the hemorrhoid tissue, just above the dentate line. This cuts off the blood supply, causing the hemorrhoid to shrink and fall off within a week or two, leaving a small scar that prevents recurrence in that location.

What the evidence shows: A 2022 systematic review and meta-analysis published in the GE Portuguese Journal of Gastroenterology found that RBL significantly outperformed sclerotherapy in controlling both prolapse (93.1% vs. 66.4%) and bleeding (89.1% vs. 78.7%), while patient satisfaction rates were also notably higher with RBL (77.8% vs. 46.7%).¹ The tradeoff is that post-procedural pain is more common after banding — roughly 24% of RBL patients experience it compared to 14% after sclerotherapy.¹

RBL is typically performed in a gastroenterologist’s or colorectal surgeon’s office and requires no sedation. Most patients return to work the same day, though mild discomfort and a sensation of pressure for 24–72 hours is common. Multiple sessions (usually spaced four to six weeks apart) may be needed to treat hemorrhoids at different positions.

Best suited for: Grades I–III internal hemorrhoids, particularly those with significant prolapse or persistent bleeding that hasn’t responded to conservative care.

Sclerotherapy

Sclerotherapy has been used to treat hemorrhoids since the late 19th century. While it has largely been displaced by rubber band ligation in many practices, it remains a valuable tool — especially for patients who cannot tolerate banding or who are on anticoagulant therapy.

How it works: A sclerosant solution is injected directly into the tissue of the hemorrhoid. The chemical causes inflammation and fibrosis, which shrink the tissue and obliterate the feeding blood vessels.

What the evidence shows: When compared head-to-head with RBL, sclerotherapy holds its own for certain outcomes. A 2024 clinical study enrolling 80 patients with Grade II hemorrhoids found that while both procedures reduced symptoms effectively, sclerotherapy patients reported significantly lower pain scores by Day 3 post-procedure and through the first three months.² For patients with low pain tolerance or a history of post-banding discomfort, this is a meaningful difference. The catch is that sclerotherapy tends to be less durable for prolapse control, and repeat injections are often needed.

Best suited for: Grade I–II internal hemorrhoids; patients on blood thinners; patients who experience significant pain with banding; elderly or frail patients who are poor surgical candidates.

Hemorrhoid Artery Embolization: The Newest Frontier

Hemorrhoid artery embolization is the newest non-surgical option in the hemorrhoid treatment landscape, and it is rapidly gaining traction in interventional radiology practices worldwide. Unlike banding and sclerotherapy — which target the hemorrhoidal tissue directly — HAE addresses the problem upstream by reducing the blood supply that feeds the hemorrhoidal cushions.

How it works: Under X-ray or fluoroscopic guidance, an interventional radiologist inserts a thin catheter through the wrist or upper thigh artery and navigates it to the superior rectal arteries (and sometimes the middle rectal arteries) that supply blood to the hemorrhoidal tissue. Tiny embolic particles or microcoils are then deployed to reduce that blood flow. The hemorrhoids lose their blood supply, shrink over the following weeks, and symptoms resolve without any tissue excision.

What the evidence shows: A 2023 study published in the Journal of Vascular and Interventional Radiology analyzed 134 patients who underwent outpatient HAE. Successful embolization of at least one hemorrhoidal artery was achieved in 133 of 134 patients (99%), and clinical success — defined as symptom improvement without additional treatment — was seen in 93% of patients at one-month follow-up.³ All key outcomes improved significantly: hemorrhoid symptom scores dropped from 11 to 7.8, hemorrhoid-related pain dropped from 4.1 to 1.3 on a 10-point scale, quality of life scores improved, and bleeding scores were nearly halved — all with no severe adverse events.³

Longer-term data is accumulating. A separate analysis of superior rectal artery embolization found that 72% of patients maintained clinical success at 12 months, and another cohort study in patients with contraindications to surgery showed an 84.4% rate of sustained symptom relief at one year or more.⁴

The major practical advantage of HAE is its minimal recovery profile. The procedure is performed under conscious (twilight) sedation on an outpatient basis, and most patients return to normal daily activities within 24–48 hours. Because no tissue is cut, burned, or banded, post-procedural pain is significantly lower than with RBL.

Best suited for: Grades I–III internal hemorrhoids with persistent bleeding; patients who have failed rubber band ligation or sclerotherapy; patients on anticoagulants who are high surgical risk; patients who want to avoid any anesthesia or tissue manipulation; those with refractory symptoms.

Side-by-Side Comparison: Key Factors at a Glance

Which Treatment Is Right for You?

The honest answer is: it depends — and that’s why a conversation with a specialist is so important.

Rubber band ligation remains the workhorse of hemorrhoid treatment for most patients with Grade II or III internal hemorrhoids. It is widely available, cost-effective, and highly effective for both bleeding and prolapse. If post-banding pain is a concern, sclerotherapy offers a gentler alternative — particularly for Grade I–II disease or for patients on anticoagulant therapy.

Hemorrhoid artery embolization represents an exciting evolution in non-surgical hemorrhoid treatment. It is particularly compelling for patients who have not responded to banding or sclerotherapy, those who cannot tolerate even minor procedural discomfort, or those whose medications or health status make surgery riskier. As more long-term data emerges, HAE may well move earlier in the treatment algorithm.

The most important takeaway: hemorrhoids do not require surgery for most people. If you’ve been living with chronic discomfort, rectal bleeding, or prolapse and haven’t yet explored these options, it’s worth asking your doctor which non-surgical path makes the most sense for your specific situation.
