Sometimes, there is a tear in the skin around the anal passage, which is called anal fissure. It is a common condition but can cause acute pain, especially during or after a bowel movement. At times, it can cause bleeding. An anal fissure is associated with spasms of the internal anal sphincter. The spasms interrupt blood supply to the region, which prevents healing. Treatment for anal fissure is aimed to resume the smooth flow of blood to the area.
Treatments begin with eating more fiber and drinking more liquid, ointments, laxatives, and injection of botulinum toxin. Surgery is only recommended when these methods fail to heal an anal fissure.
Sphincterectomy involves the splitting of the sphincter. The surgeon makes a small cut in the skin near the anal passage and cut the lower part of the internal sphincter muscle. This will stop the spasms in the sphincter muscle and allow proper flow of blood, which will cause the anal fissure to heal.
The operation usually lasts for fifteen minutes and is performed under general anesthesia
Pain and bleeding can be the usual complications of sphincterotomy. Significant complications may be involuntary passing wind or lose motions, difficulty in passing urine or permanent incontinence or infection.
Patients usually go home the same day. The fissure heals quickly so the pain generally subsides soon. Patients can often return to work in a few days, depending on his or her occupation. Exercising during convalescence helps in better and faster recovery. Consult your doctor about a workout plan.
There can be another anal fissure in the future.
