Which Method Is the Definitive Solution?

This article is the final part of our Anismus series.

In our previous articles, we explained that patients who experience difficulty in defecation may face two different situations:

  • Some patients truly cannot relax their anal muscles (Anismus).
  • Others actually have a physical obstruction in the anal canal (such as Anal Stenosis or Rectal Prolapse).

This distinction is extremely important because treatment depends entirely on the underlying cause.

So what happens after the diagnosis is made?

Should every patient receive the same medication, exercise program, or surgery?

At our clinic, we apply a personalized treatment algorithm that depends on the origin of the problem:

  • Is it a functional problem (muscle coordination)?
  • Or a structural problem (mechanical obstruction)?

Below is the treatment roadmap used after a correct diagnosis.

Group 1: True Anismus (When the Problem Is in the Muscles)

If no narrowing, prolapse, or rectal hernia is detected during examination and diagnostic tests, the condition is considered functional Anismus.

This means the muscles themselves are healthy, but the brain sends incorrect signals during defecation, causing the muscles to contract instead of relaxing.

In such cases, surgery is not recommended, because cutting or weakening the muscles does not solve the neurological coordination problem. Moreover, unnecessary surgical interventions can increase the risk of gas or fecal incontinence in the future.

Biofeedback Therapy

Biofeedback therapy is considered the first-line treatment for Anismus.

This computer-assisted therapy retrains the patient’s body to restore the correct reflex:

Relaxation of the anal muscles during straining.

During several therapy sessions, patients learn to correct the faulty brain–muscle communication that causes the disorder.

Over time, the brain “reprograms” the correct defecation pattern.

Botox Injection for Anismus

In some patients, muscle memory may be very strong and Biofeedback alone may not be sufficient.

In these cases, Botox injections are applied to the muscles responsible for contraction, such as:

  • Puborectalis muscle
  • Internal anal sphincter

The purpose of Botox is to temporarily paralyze the muscle for approximately 4–6 months.

During this time:

  • The muscle remains relaxed
  • The patient can defecate without difficulty
  • The brain learns the pattern of painless and normal bowel movement

Group 2: Anal Stenosis (When the Problem Is a Narrowing)

If the anal canal has narrowed due to previous surgeries such as:

  • Hemorrhoid surgery
  • Anal fissure surgery
  • Laser procedures

the condition is known as Anal Stenosis.

In this situation, telling the patient to relax or applying Botox will not solve the problem.

This is because the issue is not muscle contraction, but rather that the anal opening has physically shrunk due to scar tissue.

Surgical Solution: Flap Reconstruction

Treatment requires surgical correction.

The most effective method is flap reconstruction surgery.

During this procedure:

  • The hardened scar tissue causing the narrowing is removed.
  • Healthy and flexible skin with good blood supply is transferred from nearby tissue.

Common techniques include:

  • Hause Flap
  • Y-V Flap
  • Diamond Flap

Expected Result

After reconstruction:

  • The diameter of the anal canal is widened
  • Tissue elasticity is restored
  • Defecation becomes easier

Many patients report significant relief after surgery and often say they had been straining unnecessarily for years.

Group 3: Rectal Prolapse and Rectocele (When the Problem Is an Obstruction)

In some patients, the rectum may collapse downward during straining, blocking the anal canal.

This condition is called Occult Rectal Prolapse.

Another structural problem is Rectocele, where part of the rectum forms a hernia-like pouch.

In both cases, the bowel movement pathway is physically obstructed.

Without removing the obstruction, complete recovery is unlikely.

Mucosal Excision (Mild to Moderate Prolapse)

In early or moderate stages, treatment may involve removal of the excess sagging mucosal tissue.

This procedure clears the anal canal and restores the normal pathway of stool passage.

It is often performed together with hemorrhoid or fissure surgery.

Rectopexy (Advanced Prolapse)

If the prolapse is more severe and involves the entire thickness of the rectal wall, a more advanced procedure may be required.

This surgery is called Rectopexy.

It can be performed using:

  • Laparoscopic techniques
  • Open abdominal surgery

During the procedure, the rectum is lifted and fixed into its normal anatomical position.

Expected Result

Once the prolapse is corrected:

  • The “plug effect” disappears
  • The rectum returns to its normal alignment
  • Defecation becomes easier and more natural

Conclusion: There Is No One-Size-Fits-All Treatment

Many patients feel discouraged and say:

“I have Anismus and nothing seems to help.”

However, the real problem may simply be that the wrong condition was diagnosed.

Treatment depends entirely on identifying the true cause of the symptoms.

The correct treatment approach can be summarized as follows:

  • Muscle contraction → Biofeedback therapy and Botox
  • Anal narrowing → Flap reconstruction surgery
  • Rectal prolapse → Rectopexy or mucosal excision

Once the correct diagnosis is made—whether the problem is functional or mechanical—an effective treatment plan can be created.

Consulting an experienced proctology specialist is the most important step toward finding the right solution.

Frequently Asked Questions (FAQ)

Does Anismus go away on its own?

Unfortunately, no.

Anismus develops due to a mislearned reflex between the brain and the anal muscles. Without proper treatment such as Biofeedback therapy or Botox injections, this incorrect reflex usually persists and may become chronic.

Over time, untreated Anismus can also lead to secondary conditions such as:

  • Anal fissures
  • Hemorrhoids
  • Chronic constipation

Are Kegel exercises helpful for Anismus?

No. In fact, Kegel exercises can make the condition worse.

Kegel exercises are designed to strengthen and tighten pelvic muscles. However, in Anismus the muscles are already over-contracted and tense.

Instead of strengthening the muscles, treatment should focus on relaxation and coordination training.

A Relaxation Exercise That May Help

Before using the toilet or while bathing:

  1. Apply a small amount of anesthetic cream or olive oil to your finger.
  2. Gently insert the finger into the anus.
  3. Stretch the anal muscles gently in four directions (12, 3, 6, and 9 o’clock positions).
  4. Hold the stretch for about 20 seconds in each direction.

This stretching movement can help break the locked muscle memory and encourage relaxation of the anal muscles.
