Introduction
Anal fissures are a common and painful condition that can significantly affect a patient’s quality of life. They often cause sharp pain during and after bowel movements, along with bleeding and persistent discomfort.
While many cases can be treated with conservative methods, chronic cases may require surgical intervention to achieve a definitive and effective solution.
In this comprehensive guide, you will learn everything about anal fissure surgery, including its causes, symptoms, treatment options, and recovery process.
What Is an Anal Fissure?
An anal fissure is a small tear in the lining of the anal canal, usually caused by passing hard stools or straining during bowel movements.
Fissures can be classified as:
- Acute: Appears suddenly and heals within a short time
- Chronic: Persists for a longer period and may require medical or surgical treatment
Causes of Anal Fissure
Anal fissures can occur due to several factors, including:
- Chronic constipation
- Passing hard stools
- Recurrent diarrhea
- Straining during bowel movements
- Reduced blood flow to the area
- Childbirth (in women)
Symptoms of Anal Fissure
Common symptoms include:
- Severe pain during bowel movements
- Pain that continues after passing stool
- Bright red bleeding
- Itching or irritation
- Muscle spasm in the anal area
When Is Surgery Needed?
Not all cases require surgery, but it is recommended in the following situations:
- Symptoms persist for more than 6–8 weeks
- Failure of medical treatment
- Severe and ongoing pain
- Recurrent fissures
What Is Anal Fissure Surgery?
Anal fissure surgery is a simple procedure aimed at reducing tension in the anal sphincter muscle and improving blood flow, allowing the fissure to heal.
The most common procedure is:
Lateral Internal Sphincterotomy
How Is the Surgery Performed?
Procedure Steps:
- Local or general anesthesia is administered
- A small incision is made in the internal sphincter muscle
- Pressure in the anal canal is reduced
- The wound is left to heal or closed depending on the case
The procedure typically takes 15–30 minutes.
Benefits of Surgery
- Very high success rate (over 90%)
- Rapid pain relief

Recovery Timeline:

- Full recovery within 2–4 weeks
Post-Surgery Tips:

- Drink plenty of water
- Use stool softeners if needed
- Take warm sitz baths
