Sphincterotomy for Fissure

Anal fissure/ Fissure in ano is a a small tear in the skin of the anal canal. It is usually caused by constipation (passage of hard stools) and occasionally by loose watery stools. Though not a dangerous condition by itself, it can be extremely distressing for the patient.

Signs & symptoms:

Painful defecation (while passing stool). The intensity is very severe in acute fissure and may be less in chronic cases.
Bleeding with stools.

Lateral internal sphincterotomy/ Fissurectomy:

This is the surgery performed for anal fissures that fail medical therapy. It is a minor operation and can also be carried out as a day care procedure. In this surgery, a small segment of the internal sphincter muscle is divided to lower the resting pressure. It leaves a small wound on the anal verge and does not require any dressing.
