The goal of surgery is to help the anal sphincter muscle relax which reduces pain and spasms, allowing the fissure to heal. Surgical options include Botulinum toxin (Botox®) injection into the anal sphincter or surgical division of an inner part of the anal sphincter (lateral internal sphincterotomy).

What is the procedure for fissure surgery?

In an open sphincterotomy, the surgeon makes a small cut in the skin to reach the sphincter muscle. Once the sphincter muscle is visible, the surgeon cuts into it. In this method, the incision may be left open to heal. In a closed sphincterotomy, the surgeon passes a blade under the skin to access the sphincter muscle.

How long does it take to heal from fissure surgery?

It is important to note that complete healing with both medical and surgical treatments can take up to approximately 6-10 weeks. However, acute pain after surgery often disappears after a few days. Most patients will be able to return to work and resume daily activities in a few short days after the surgery.
