Lateral Internal Sphincterotomy (LIS) is a surgical procedure commonly performed to treat chronic anal fissures that have not responded to non-surgical treatments. An anal fissure is a small tear in the lining of the anus that can cause severe pain, discomfort, and bleeding during bowel movements. LIS involves making a small incision in the internal anal sphincter muscle to reduce tension and promote healing of the fissure.
LIS is typically recommended for patients with chronic anal fissures that have not responded to conservative treatments such as medications, dietary changes, or Botox injections.
Chronic Anal Fissures: Fissures that have persisted for more than six weeks despite other treatments.
Severe Pain: Intense pain during bowel movements that interferes with daily life.
Failed Non-Surgical Treatments: Fissures that do not respond to conservative measures, such as fiber supplements, topical ointments, or sitz baths.
During an LIS procedure, the surgeon will cut a small portion of the internal anal sphincter muscle to reduce muscle tension, which helps the fissure heal and alleviates pain. The procedure is typically performed on an outpatient basis and usually takes less than an hour. The patient is placed under general anesthesia or local anesthesia with sedation to ensure comfort. A small incision is then made in the internal anal sphincter muscle to reduce pressure in the anal canal. The fissure is allowed to heal naturally as the muscle tension decreases. Finally, the incision is closed with sutures, and the patient is moved to recovery.
Most patients experience significant relief from pain within a few days after surgery, with recovery being generally quick. Most people return to normal activities within a week. Pain management typically involves over-the-counter or prescription medications to relieve post-operative discomfort. Additionally, dietary adjustments, such as a high-fiber diet and plenty of water, can help prevent constipation and strain during bowel movements, promoting healing. It’s important to avoid heavy lifting or strenuous activities until your surgeon gives you clearance to ensure proper recovery.
If you’re suffering from chronic anal fissures, LIS may be the solution to relieve pain and promote healing. Schedule a consultation with Texas Advanced Surgical & Bariatrics to discuss your symptoms and determine the best treatment option.

Most patients can resume normal bowel movements within a day or two after surgery. It’s important to follow dietary recommendations to avoid constipation and straining.
Non-surgical treatments, such as topical creams, Botox injections, and dietary changes, may be effective for some patients. However, if these treatments fail, LIS is often the next step.
If the fissure does not heal after LIS, further evaluation will be needed to determine the cause. Additional treatments or surgical interventions may be considered.
Most patients can return to non-strenuous work within a few days to a week. If your job requires physical labor, your surgeon may recommend taking a longer time off.
LIS has a success rate of over 90%, making it one of the most effective treatments for chronic anal fissures.
