What is Anal Fissure Surgery?

An anal fissure is a small tear in the lining of the anal canal that causes severe pain and bleeding during bowel movements. While most fissures heal with conservative treatment, some become chronic and require surgery. Anal fissure surgery, typically performed as a lateral internal sphincterotomy, helps reduce anal muscle spasm, improves blood flow, and promotes healing of the fissure, offering long-term relief.

When is it Needed?

• Persistent anal pain and bleeding despite medical treatment
• Chronic fissures lasting more than 6–8 weeks
• Recurrent fissures causing ongoing discomfort
• Severe muscle spasm preventing natural healing
• Associated complications like sentinel pile or hypertrophied papilla

How the Surgery Works

The most common procedure is Lateral Internal Sphincterotomy (LIS), in which a small portion of the internal anal sphincter muscle is cut to reduce spasm and pressure in the anal canal. This allows better blood flow and promotes healing of the fissure. The surgery is performed under local, spinal, or general anesthesia and usually takes less than 30 minutes. In some cases, laser-assisted fissure surgery may be used for quicker recovery and less post-operative discomfort.

Benefits of Anal Fissure Surgery

• Permanent relief from pain and bleeding
• High success rate in healing chronic fissures
• Quick procedure with minimal hospital stay
• Reduced recurrence compared to medical therapy
• Improved quality of life and comfort in daily activities

Recovery and Aftercare

Most patients are discharged the same day or within 24 hours after surgery. Mild discomfort, swelling, or minor bleeding may occur but usually settles within a few days. Patients are advised to maintain a high-fiber diet, stay hydrated, and practice good anal hygiene. Sitz baths (warm water soaks) may help relieve discomfort. Regular follow-up visits are important to monitor healing and ensure there are no complications.

Why Choose Anal Fissure Surgery?

Anal fissure surgery is a safe and highly effective option for patients who have not found relief through medicines and lifestyle changes. With modern techniques like laser-assisted surgery, recovery is faster, pain is minimal, and long-term results are excellent. Choosing surgical treatment ensures permanent relief, restoring confidence and comfort in daily life.
