Anal Fissures: How Botox Can Help You Avoid Surgery

By Carolina Rectal Health Institute

If you have severe pain with bowel movements that feels like passing broken glass, followed by burning or aching that lasts for hours, you may have an anal fissure. Although many people assume they have hemorrhoids, anal fissures are actually one of the most common causes of anal pain—and fortunately, they are very treatable.

At Carolina Rectal Health Institute, we specialize in diagnosing and treating anal fissures. While many patients heal with medications alone, others benefit from a simple office-based Botox injection that can relieve pain, promote healing, and often eliminate the need for surgery.

What Is an Anal Fissure?

An anal fissure is a small tear in the lining of the anal canal. It most commonly develops after:

• Passing a hard bowel movement

• Chronic constipation

• Repeated diarrhea

• Childbirth

• Trauma to the anal canal

Once a fissure develops, the internal anal sphincter often goes into spasm. This muscle spasm decreases blood flow to the area, making it difficult for the tear to heal. The result is a vicious cycle:

Pain → Muscle Spasm → Reduced Blood Flow → Poor Healing → More Pain

Breaking this cycle is the key to successful treatment.

Symptoms of an Anal Fissure

Patients commonly describe:

• Sharp, severe pain during bowel movements

• Burning pain lasting minutes to several hours afterward

• Bright red blood on the toilet paper

• Fear of having bowel movements because of the pain

• A small skin tag (“sentinel tag”) near the fissure in chronic cases

Many patients suffer for months before seeking care because they assume the problem is hemorrhoids.

Initial Treatment

Many fissures heal without surgery.

Initial treatment focuses on:

• Keeping stools soft

• Drinking plenty of water

• Increasing dietary fiber

• Warm sitz baths

• Prescription topical medications that relax the anal sphincter

These treatments work well for many patients, especially when the fissure is caught early.

However, chronic fissures often require additional treatment.

Botox: A Simple Office-Based Solution

Botox (botulinum toxin) works by temporarily relaxing the internal anal sphincter muscle.

When the muscle relaxes:

• Pain decreases dramatically

• Blood flow improves

• The fissure is able to heal naturally

Unlike cosmetic Botox, the goal is not appearance—it is to stop the muscle spasm preventing healing.

An Office Procedure That Takes Only Minutes

One of the biggest advantages of Botox treatment at Carolina Rectal Health Institute is that most patients do not need the operating room.

The procedure is:

• Performed right in our office

• Takes only a few minutes

• Requires no incisions

• Usually requires little or no downtime

• Allows patients to return to normal activities quickly

Most patients tolerate the procedure very well.

Does Botox Hurt?

The injection itself is brief. We use topical lidocaine to keep the injection from hurting.

Many patients tell us the anticipation is worse than the procedure itself, especially because they have already been experiencing severe fissure pain.

The discomfort from the injection is typically minimal compared with the pain of an untreated fissure.

How Well Does Botox Work?

Botox has an excellent success rate for appropriately selected patients.

Many patients experience:

• Less pain within several days

• Continued improvement over the next few weeks

• Complete healing without surgery

For patients whose fissure does not fully heal, Botox can often be repeated or followed by a definitive surgical procedure.

When Is Surgery Necessary?

The gold standard surgical treatment is a lateral internal sphincterotomy (LIS).

This small procedure permanently relaxes a portion of the internal sphincter and has healing rates exceeding 90%.

Although surgery remains an outstanding option for chronic fissures, many patients prefer to try Botox first because:

• There is no incision

• Recovery is easier

• It can often avoid surgery altogether

• There is virtually no recovery time

During your consultation, we will discuss which option is best for your specific situation.

Why See a Colorectal Surgeon?

Not every painful anal condition is a fissure.

Symptoms that seem like hemorrhoids can actually be:

• Anal fissures

• Abscesses

• Fistulas

• Skin conditions

• Inflammatory bowel disease

• Less commonly, anal cancer

An accurate diagnosis is the first step toward lasting relief.
