What is Lateral Internal Sphincterotomy?
Lateral Internal Sphincterotomy is a surgical procedure involving the anal sphincter. The anal sphincter is a muscle that controls the opening and closing of the anus. This surgery involves making a small incision in the internal anal sphincter. It helps to relieve pressure and reduce pain.
This surgery is often needed for chronic anal fissures. Anal fissures are small tears in the lining of the anus. They cause pain and bleeding during bowel movements. If left untreated, they can lead to persistent pain and discomfort. Modern surgical approaches for Lateral Internal Sphincterotomy include open and closed techniques. These methods aim to provide relief and promote healing.

Everything you need to know about the procedure, preparation, and recovery
Lateral Internal Sphincterotomy Surgery Indications
Lateral Internal Sphincterotomy is often recommended for patients with chronic anal fissures that do not heal with conservative treatments. This procedure helps relieve pain and promote healing by reducing the pressure in the anal sphincter.
Chronic Anal Fissures
Patients experience severe pain during bowel movements, often accompanied by bleeding. On examination, doctors find a tear in the anal lining that persists for more than six weeks. When ointments and dietary changes fail to heal the fissure, surgery is considered.
Recurrent Anal Fissures
Patients report repeated episodes of sharp anal pain and bleeding. Examination reveals multiple fissures or a single fissure that reopens frequently. When lifestyle modifications and medications do not prevent recurrence, surgical intervention is advised.
High Anal Sphincter Pressure
Patients may feel persistent discomfort or pain in the anal area. Manometry tests show elevated resting pressure in the anal sphincter. If pressure does not decrease with medication, surgery is needed to relax the sphincter.
Non-healing Fissures
Patients suffer from ongoing pain and bleeding despite using topical treatments. Examination shows a chronic fissure with signs of fibrosis. When healing stalls despite conservative management, surgery becomes necessary.
Associated Anal Spasms
Patients experience spasmodic pain in the anal region. Examination and patient history indicate spasms linked to fissures. If muscle relaxants and other treatments fail, surgery is recommended to alleviate the spasms.
How to Prepare for Lateral Internal Sphincterotomy?
Proper preparation is crucial for a smooth Lateral Internal Sphincterotomy. It helps reduce complications and ensures a quicker recovery.
- Medication Review: Stop NSAIDs, anticoagulants, and herbal supplements as advised by your doctor.
- Fasting: Fast for at least 6-8 hours before the procedure to prepare for anaesthesia.
- Bowel Preparation: Follow any bowel prep instructions given by your healthcare provider to ensure a clean surgical area.
- Comfortable Clothing: Wear loose, comfortable clothing on the day of the surgery for ease after the procedure.
- Transportation: Arrange for someone to drive you home post-surgery as you may feel drowsy from anaesthesia.
- Medication List: Bring a list of all medications you take, including dosages, for the medical team to review.
- Pre-Surgery Instructions: Follow any specific instructions provided by your surgeon to ensure a successful procedure.
- Hydration: Stay well-hydrated the day before the surgery unless instructed otherwise.
Lateral Internal Sphincterotomy Surgery (Step-by-Step)
Overview: This procedure is performed by gastroenterologists. It typically takes about 15 to 30 minutes. Local anaesthesia is commonly used, but general anaesthesia may be considered in some cases.
- Preparation: The patient is positioned comfortably. Local anaesthesia is administered to numb the area, ensuring the patient feels minimal discomfort.
- Incision: A small incision, about 1-2 cm, is made near the anal opening. This allows access to the internal anal sphincter.
- Muscle Identification: The surgeon identifies the internal sphincter muscle using a small retractor. This step ensures precision in the procedure.
- Sphincterotomy: A surgical instrument, such as a scalpel or bipolar cautery, is used to make a controlled cut in the sphincter muscle. This helps reduce pressure and promotes healing.
- Closure: The incision may be left open to heal naturally or closed with sutures, depending on the surgeon's preference and the patient's condition.
- Recovery: The patient is monitored for a short period before being discharged. Post-operative instructions are provided to aid recovery.
