Operation
A chronic fissure is a non-healing wound in the anal canal, present for weeks or months.
When performing a fissurectomy, the wound edges and the base of the wound are excised. The aim is to stimulate wound healing from the bottom up starting from a healthy wound base.
During a lateral sphincterotomy, the muscle of the internal sphincter muscle is incised to reduce the tension in the anal canal which will increase the blood supply and improve the healing of the anal fissure.
The anal sphincterotomy will decrease the spasm and the pain.
After surgery, the pain when expelling bowel movements (exoneration) will disappear after just a few days.
After surgery, the patient experiences pain similar to a bruising for an average of 2 to 6 days,
The pain is different from the tearing and stabbing pain experienced with the anal fissure.
Healing of anal fissure takes an average of 4-5 weeks. The sutures of the wound are resorbable and can be palpated at the edge of the anus for the first few weeks.

If you are unable to contact your GP or your surgeon, go to the emergency department at St Elizabeth Hospital in Uccle.
This procedure should not be performed in patients with a weak anal sphincter tonus or in female patients with a history traumatic deliveries. For these patients, other procedures should be preferred, such as Botox infiltration or a rectal mucosal or perianal skin flap.
