Anal Fissure Treatment in Turkey: Non-surgical options, surgery & recovery

What Is an anal fissure and what causes it?

An anal fissure is a small tear in the skin lining the anal canal, most often caused by the passage of hard or large stools. Common contributing factors include:

• Chronic constipation or straining during bowel movements
• Severe or prolonged diarrhea.
• Childbirth.
• Reduced blood flow to the anal area (more common with age).
• Underlying conditions such as Crohn's disease, in some cases.

Typical symptoms:

• Sharp, burning pain during and after bowel movements, sometimes lasting several hours.
• Bright red blood on the stool or toilet paper.
• A visible tear or skin tag near the anus.
• Anal itching or spasm of the anal sphincter, which can intensify the pain.

How is an anal fissure diagnosed?

A proper diagnosis is important because anal fissures share symptoms with other conditions, such as hemorrhoids, anal fistulas, and abscesses. Less commonly, they are confused with anal cancer. A misdiagnosis can lead to the wrong treatment and prolonged discomfort.

A colorectal surgeon or proctologist will typically diagnose an anal fissure by:

• Patient history, including bowel habits, pain pattern, and any bleeding.
• Visual examination: Most fissures are visible externally without an internal exam.
• Anoscopy, when needed. This is a short, painless examination that uses a small instrument to confirm the exact location of the fissure and rule out other causes, particularly for atypical or non-healing fissures.

If you notice bleeding, it's worth having it evaluated by a doctor rather than assuming it's "just a fissure," since bleeding can be a symptom of a different, sometimes more serious, condition.

How is an anal fissure treated without surgery?

Around 70% of acute (new) anal fissures heal on their own within about 4 weeks with simple, non-surgical measures. Turkish colorectal specialists typically start with:

Dietary and lifestyle changes

• Increasing fiber intake (fruits, vegetables, whole grains) to soften stools and reduce straining.
• Drinking plenty of water throughout the day.
• Regular physical activity to support healthy bowel movements.
• Avoiding prolonged sitting on the toilet.

Topical treatments

• Nitroglycerin (nitrate) ointments: these relax the internal anal sphincter, improving blood flow to the area and helping the fissure heal, scarring is simply part of the body's natural healing process once the tear closes, not an outcome the treatment specifically targets.
• Calcium channel blocker creams (such as diltiazem): an alternative to nitrates with a similar muscle-relaxing effect and generally fewer headaches as a side effect.

Warm sitz baths

Sitting in warm water for 10-15 minutes several times a day, especially after bowel movements, helps relax the anal sphincter, improves local blood flow, and eases pain, simple, low-cost, and genuinely effective for many patients.

Botox injections for anal fissure

When creams alone aren't enough, but before considering surgery, many colorectal surgeons in Turkey offer botulinum toxin (Botox) injections directly into the internal anal sphincter. Botox temporarily blocks the nerve signal that keeps the sphincter tightly contracted, allowing it to relax for about 2-3 months, often enough time for the fissure to heal fully. It's a minimally invasive option, performed without general anesthesia, and is particularly suited to patients who want to avoid surgical risk or who aren't ideal surgical candidates.

When is surgery needed for an anal fissure?

Surgery is generally considered a later step, reserved for chronic fissures (lasting more than 6-8 weeks) that haven't responded to topical treatment, Botox, or lifestyle changes. Depending on your specific case, your colorectal surgeon may recommend one of the following:

Fissurectomy

A straightforward procedure to remove the fissure and surrounding scarred tissue, performed under local or regional anesthesia in about 30 minutes. Most patients go home the same day.

Anoplasty

Involves covering the fissure with a flap of healthy tissue from the surrounding area, promoting faster and more effective healing. Typically used for larger or more complex fissures, or after a previous treatment hasn't fully resolved the issue.

Lateral internal sphincterotomy (LIS)

It is the most common surgical option for chronic fissures and, according to published clinical literature, generally the most effective. The surgeon makes a small, partial incision in the internal anal sphincter, which is the muscle that maintains continence and tone in the anal canal. Relaxing part of this muscle relieves the excess pressure that prevents the fissure from healing without cutting through the entire sphincter. The procedure is typically performed under local or regional anesthesia, and most patients go home the same day.

Comparing the surgical options

What are the risks and success rates of anal fissure surgery?

Anal fissure surgery, and lateral internal sphincterotomy in particular, is generally considered safe and effective, with published success rates commonly cited in the 90-100% range for symptom relief and healing. As with any procedure, it carries some risks:

• Infection at the surgical site: uncommon with proper post-operative care.
• Temporary gas or minor stool leakage (incontinence): The most specific risk of sphincterotomy, since it involves the muscle controlling continence; this is typically mild and resolves on its own, but should be discussed with your surgeon beforehand, especially if you have any pre-existing bowel control concerns.
• Recurrence: possible with any treatment option, though sphincterotomy generally has one of the lowest recurrence rates among the available approaches.
• Delayed wound healing, more common with underlying conditions such as poorly controlled diabetes or Crohn's disease.

Your surgeon will review your specific health history to determine which option offers the best balance of effectiveness and risk for your situation.

How to care for yourself after treatment?

No matter which option you and your surgeon choose, there are a few practical steps that can support healing.

• Keep the area clean and dry. Gentle, warm sitz baths several times a day promote hygiene and comfort.
• Avoid heavy lifting and strenuous exercise for the first one to two weeks after surgery.
• Maintain a high-fiber diet, and drink plenty of water to keep stools soft and avoid straining.
• Take prescribed pain relievers and stool softeners as directed.
• Avoid prolonged sitting. Short, frequent walks support circulation and comfort.

Most patients can resume normal daily activities within a week, though full healing typically takes a few weeks, up to four to six weeks for lateral internal sphincterotomy.
