What is Hemorrhoidal Artery Ligation?

Hemorrhoidal artery ligation (HAL) — also known as transanal hemorrhoidal dearterialization (THD) or Doppler-guided hemorrhoidal artery ligation (DGHAL) — is a minimally invasive, non-excisional procedure for treating hemorrhoids. Instead of cutting away hemorrhoidal tissue, the surgeon uses a specially designed proctoscope fitted with a Doppler ultrasound probe to precisely locate and tie off (ligate) the small arteries that carry blood to the hemorrhoids. Without this blood supply, the swollen hemorrhoidal cushions shrink naturally over the following days and weeks.

When internal hemorrhoids have slipped down out of the anal canal, the ligation is combined with a stitching method called mucopexy or recto-anal repair (RAR). This step uses a continuous stitch to pull and lift the slipped tissue back to its proper place inside the anal canal. This combined treatment is often called HAL-RAR or THD with mucopexy.

Who is a candidate for hemorrhoidal artery ligation?

Hemorrhoidal artery ligation is suitable for a wide range of patients. You may be a good candidate if you have:

• Grade II hemorrhoids (which prolapse during straining but return on their own) that have not responded to conservative treatments such as dietary changes, topical medications, or office-based procedures like rubber band ligation.
• Grade III hemorrhoids (which prolapse and require manual reduction) where bleeding and discomfort are the primary concerns.
• Grade IV hemorrhoids (permanently prolapsed) in selected cases, particularly when combined with the mucopexy component.
• A strong preference for a procedure that avoids cutting, excision, or the creation of external wounds.
• Medical conditions or anticoagulant medications that make bleeding from excisional surgery a concern.
• Previous hemorrhoid procedures that did not provide lasting relief and are looking for an alternative approach.

Patients with large external hemorrhoid components or significant perianal skin disease may not achieve optimal results with HAL alone and may require a conventional or combined approach. Your surgeon will assess your hemorrhoid grade and anatomy through a careful examination before recommending treatment.

What are the differences between hemorrhoidal artery ligation and other hemorrhoid treatments?

Compared to conventional hemorrhoidectomy, HAL causes significantly less post-operative pain because no tissue is cut or removed from the pain-sensitive perianal skin. There are no open wounds, no dressings required, and patients typically return to normal activities within two to three days rather than two to four weeks.

Compared to stapler hemorrhoidectomy (PPH), HAL is similarly non-excisional in philosophy but avoids the use of a mechanical stapling device entirely. This eliminates rare but serious stapler-related complications such as rectovaginal fistula or staple line dehiscence. HAL also does not permanently alter the anatomy of the anal canal.

Compared to laser hemorrhoidopexy, HAL uses Doppler-guided precision suturing rather than heat energy. Both are non-excisional and minimally painful, but HAL has a particularly strong evidence base built over more than two decades of clinical use and is recognized in major colorectal surgical guidelines worldwide.

Compared to rubber band ligation (a common office procedure), HAL can treat higher grades of hemorrhoids and larger prolapsed tissue that would not respond adequately to banding alone. It also addresses all hemorrhoidal columns simultaneously in a single procedure.

How does the procedure work?

The key to HAL is the Doppler ultrasound component built into the operating proctoscope. Arteries carrying blood to the hemorrhoids are too small to see with the naked eye, but they produce a distinctive sound when the Doppler probe passes over them. The device converts this arterial flow into an audible signal — a pulsating "whoosh" — that allows the surgeon to pinpoint the exact location of each feeding artery with great accuracy.

Once the artery is located, the surgeon passes a suture through a small window in the proctoscope and ties a figure-of-eight stitch around the artery, cutting off blood flow to the hemorrhoid above the pain-sensitive dentate line. This is repeated for all hemorrhoidal arteries — typically six to eight around the circumference of the anal canal. When the mucopexy component is added for prolapse, a continuous running suture is placed above each ligated artery to gather the loose prolapsed mucosa and anchor it back into its correct position higher in the anal canal.

What steps are involved in the surgical process?

HAL (with or without mucopexy) is performed as a day-care procedure, usually taking 30 to 45 minutes, in the following steps:

• Anesthesia: The patient is positioned comfortably and anesthesia is administered. The procedure can be performed under general anesthesia, spinal anesthesia, or in selected cases under local anesthesia with sedation, depending on the patient's health and preference.
• Insertion of the HAL Proctoscope: The surgeon gently inserts the specialized operating proctoscope into the anal canal. This device has a built-in Doppler probe and an illuminated window through which sutures can be placed.
• Doppler Mapping: The surgeon slowly rotates the proctoscope around the anal canal while activating the Doppler probe. Each time the probe detects an arterial pulse, the characteristic sound signals the precise location of a hemorrhoidal feeding artery. The surgeon marks or notes each location — typically finding six to eight arteries.
• Artery Ligation: At each identified artery, the surgeon passes a suture through the proctoscope window and places a figure-of-eight stitch to ligate (tie off) the vessel. A secure knot is tied, confirmed by a reduction or disappearance of the Doppler signal at that point, indicating the blood flow has been successfully interrupted.
• Mucopexy (if required): For patients with prolapsed hemorrhoids, the surgeon then places a continuous running suture starting above the ligated artery and working downward toward the dentate line. As the suture is tied, it gathers the loose prolapsed tissue like a drawstring and lifts it back into its correct anatomical position, where it is anchored securely.
• Completion: All ligation and mucopexy sutures are placed and the proctoscope is removed. No external incisions, wounds, or staples are left behind. The patient is observed briefly and discharged home the same day in most cases.

What can be expected during the recovery period?

Recovery from hemorrhoidal artery ligation is one of the most comfortable of all hemorrhoid procedures. The vast majority of patients experience only mild rectal discomfort or a sensation of pressure for two to three days after surgery, which is typically managed with simple over-the-counter pain relievers such as paracetamol or ibuprofen. Strong prescription pain medications are rarely needed.

Since there are no external wounds, there is no wound care, no dressings, and no stitches to remove. Most patients are able to walk around comfortably within hours of the procedure and return to light work and daily activities within two to three days. More physically demanding jobs or activities that involve heavy lifting or prolonged sitting should be avoided for one to two weeks to allow the internal sutures to heal without undue stress.

Minor spotting of blood during bowel movements in the first one to two weeks is normal as the sutures dissolve and the treated hemorrhoids shrink. The full effect of the procedure — in terms of the hemorrhoids completely shrinking back — is typically apparent within four to six weeks. Keeping stools soft and avoiding straining during this healing period is essential.

What are the potential risks of hemorrhoidal artery ligation?

HAL is one of the safest treatments for hemorrhoids, with few complications. Possible risks include:

• Pain or Discomfort After Surgery: Mild to moderate pressure or discomfort in the rectal area is common in the first few days. Strong pain is rare but can happen if stitches are placed near the sensitive dentate line.
• Bleeding: Minor bleeding during or after the procedure can happen but usually stops on its own. Serious bleeding needing another surgery is rare.
• Urinary Retention: Temporary difficulty passing urine can occur after any anorectal procedure, particularly in older men. This usually resolves quickly and may require a short-term catheter.
• Thrombosis: Occasionally, the procedure can trigger thrombosis (clotting) within an external hemorrhoid, causing a painful firm lump around the anus. This is managed conservatively with warm baths and anti-inflammatory medications and usually resolves within two weeks.
• Suture-related Complications: In rare cases, the suture material can cause a localized reaction, or a suture can loosen before healing is complete. This may result in minor bleeding that resolves on its own or requires a brief office visit.
• Incomplete Relief: In some patients, particularly those with very large or Grade IV hemorrhoids, a single HAL procedure may not achieve full resolution of all symptoms and a second session or an alternative procedure may be needed.

What long-term complications might arise?

Long-term problems after HAL are rare. Sometimes they include:

• Recurrence: Hemorrhoids come back more often after HAL than after cutting surgery, especially for Grade III and IV hemorrhoids. Studies show about 10 to 20% come back within two to three years. Many return cases are mild and can be treated again with HAL or other simple office treatments.
• Ongoing Slipping: In some patients, especially those with loose tissue, the mucopexy stitching may not hold the slipped tissue permanently and it may slowly slip out again. This happens more often when Grade IV hemorrhoids are treated with HAL alone.
• Skin Tags: Existing external skin tags are not treated by HAL and will stay after the procedure. If they cause problems, a small separate surgery may be needed to remove them.
• Fecal Urgency: A small number of patients report a temporary increase in the urgency or frequency of bowel movements after the mucopexy component, as the rectum adjusts to the repositioned tissue. This typically resolves within a few months.

How successful is hemorrhoidal artery ligation in the long run?

HAL has an excellent short-term success rate, with 85 to 95% of patients achieving significant or complete resolution of their primary symptoms — particularly bleeding — immediately after the procedure. For Grade II and Grade III hemorrhoids, long-term results are very good, with studies showing sustained symptom control in the majority of patients at three to five year follow-up.

The procedure's strength lies in its safety profile and repeatability. Because HAL does not alter the anatomy of the anal canal, a repeat procedure can be performed if symptoms recur without the additional risk that comes with repeat excisional surgery. Many colorectal surgeons regard HAL as the preferred first-line surgical option for Grade II and Grade III hemorrhoids precisely because of its excellent balance of effectiveness, minimal pain, rapid recovery, and low risk.

How can one identify if the procedure has not worked correctly?

You should contact your surgeon if you notice any of the following after hemorrhoidal artery ligation:

• Continued or worsening rectal bleeding beyond the first two weeks after the procedure.
• Persistent prolapse or tissue protruding from the anus that does not reduce on its own.
• Severe pain that does not respond to standard pain medications.
• Fever, increased swelling, or foul discharge from the anal area, which may indicate infection.
• Difficulty passing stool or a sensation that the anal passage has become narrow.
• A painful, hard lump developing around the anus, which may indicate an external thrombosis.
• No improvement in symptoms after four to six weeks, suggesting the hemorrhoids have not adequately responded to dearterialization.

What are the primary advantages of hemorrhoidal artery ligation?

The most compelling advantage of HAL is that it treats hemorrhoids at their root cause — the excessive arterial blood supply — rather than simply removing the swollen tissue that results from it. By cutting off the blood flow with precision guided by Doppler ultrasound, the procedure achieves a durable result without any cutting, burning, stapling, or destruction of tissue.

This makes HAL one of the least painful surgery options for hemorrhoids, with most patients surprised by how little discomfort they feel compared to what they expected. The day procedure, no wounds, quick return to normal life, and strong safety record make it a great choice for patients who need more than simple treatments but do not want or need full surgery. It is also very flexible — working for many hemorrhoid grades and easy to repeat if needed.

Is it possible to maintain a normal lifestyle after hemorrhoidal artery ligation?

Yes. HAL is specifically designed to allow a rapid and comfortable return to normal life. Because the procedure does not alter bowel anatomy or remove any functional tissue, bowel habits are preserved exactly as before. Patients do not require special equipment, pouches, or ongoing medical devices of any kind.

Most patients return to desk work in two to three days and to more active tasks in one to two weeks. Travel, exercise, and social activities fit well with recovery. The main lifestyle change needed for lasting success is diet: eating more fiber, drinking plenty of fluids, and avoiding habits that strain the veins in the rectum.

Is a special diet required after the procedure?

There is no rigid dietary prescription, but the following habits will support your recovery and protect against recurrence:

• Increase Dietary Fiber: Aim for 25 to 35 grams of fiber per day. Excellent sources include whole grains, oats, lentils, beans, apples, pears, broccoli, and carrots. Fiber adds bulk to the stool and allows it to pass easily without straining.
• Stay Well Hydrated: Drink at least eight to ten glasses of water or non-caffeinated fluids daily. Fiber requires adequate water to work effectively; insufficient hydration can make stools harder and more difficult to pass.
• Respond to the Urge Promptly: Never ignore the urge to defecate. Delaying a bowel movement allows the stool to dry out and harden in the rectum, making it more difficult to pass and increasing the pressure on the rectal veins.
• Avoid Straining: Straining is the single most important risk factor for hemorrhoid formation and recurrence. Adopt a relaxed posture on the toilet, and if bowel movements are not easy within a minute or two, leave and try again later rather than forcing.
• Limit Alcohol and Caffeine: Both can dehydrate the body and contribute to irregular bowel habits. Moderation during the recovery period and beyond is advisable.
• Mediterranean-Style Eating: Some colorectal specialists recommend a Mediterranean-style diet rich in vegetables, healthy fats such as olive oil, fish, and antioxidants to support bowel health and reduce chronic inflammation of the rectal lining in the long term.

Your surgeon will arrange follow-up appointments to confirm that the hemorrhoids have shrunk satisfactorily, that the sutures have dissolved without complication, and that you are recovering well. Any concerns in the weeks after the procedure should be raised promptly rather than waiting for a scheduled visit.
