What is Anal Fissure Surgery?
Anal fissure surgery is a medical procedure used to treat a painful tear (fissure) in the lining of the anus. This condition can cause sharp pain and bleeding during bowel movements. Most fissures heal with simple treatments, but some long-lasting (chronic) fissures need surgery.
The most common surgery is called lateral internal sphincterotomy. In this procedure, a small part of the anal muscle is cut to reduce pressure and help the fissure heal.
This surgery improves blood flow to the area and allows the tear to heal properly. It is usually done when medicines and home treatments do not work. Anal fissure surgery is simple, effective, and provides long-term relief in most cases.
Purpose & Benefits of Anal Fissure Surgery
● Relieves severe pain during bowel movements
● Helps heal chronic anal fissures
● Reduces muscle spasm and pressure
● Improves blood flow to the affected area
● Prevents recurrence of fissures
● Provides long-term relief
● Improves quality of life
Who May Need Anal Fissure Surgery?
● Patients with chronic fissures (lasting more than 6–8 weeks)
● People who do not improve with medicines or home care
● Patients with severe pain and bleeding
● Individuals with repeated fissures
● Patients with muscle spasm in the anal area
● People with complications due to fissures
Types of Anal Fissure Surgery
1. Lateral Internal Sphincterotomy
The most common procedure. A small cut is made in the anal muscle to reduce pressure and allow healing.
2. Anal Advancement Flap
Healthy tissue is used to cover the fissure and help it heal faster.
3. Botox Injection (Non-surgical option)
Botulinum toxin is injected to relax the muscle and reduce spasm.
Anal Fissure Surgery Procedure: Step-by-Step
1. The doctor evaluates symptoms and medical history
2. Pre-surgery tests are done
3. The patient is given local or general anaesthesia.
4. The surgeon makes a small cut in the anal muscle
5. Pressure in the area is reduced
6. The fissure is allowed to heal naturally
7. The area is cleaned and sometimes dressed
8. The patient is monitored and discharged
The surgery usually takes about 30 minutes and is often done as a day-care procedure.
Recovery & Aftercare
Recovery is usually quick. Most patients can go home the same day. Mild pain, slight bleeding, or discomfort may occur for a few days.
Doctors may suggest warm water baths, a high-fibre diet, and plenty of fluids. Stool softeners may also be recommended to avoid strain during bowel movements. Full healing may take around 4–6 weeks.
Risks & Possible Complications
● Pain or discomfort after surgery
● Bleeding or infection
● Temporary difficulty controlling gas or stool
● Recurrence of fissure (rare)
● Reaction to anesthesia
These risks are uncommon, and most patients recover without serious problems.
Anal Fissure Surgery vs Other Treatments
Most anal fissures heal with non-surgical methods like diet changes, medicines, and warm baths. Surgery is only needed when these treatments do not work.
Compared to other treatments, surgery provides faster and long-lasting relief. However, it is more invasive and requires proper recovery care. Doctors usually recommend surgery only for chronic or severe cases.
