What Is Fistulotomy?

A fistulotomy is a surgical procedure aimed at treating an anal fistula, which is an abnormal connection between the epithelialised surface of the anal canal and the perianal skin. The fistulotomy surgery involves cutting open the fistula tract to allow it to heal from the inside out. A colorectal surgeon, who specialises in disorders of the rectum, anus, and colon, typically performs this procedure. 

The necessity of a fistulotomy stems from its ability to effectively heal the fistula, which reduces symptoms such as pain and discomfort, and prevents recurrent infections. The benefits of this anal fistula treatment include a high success rate and a significant reduction in the likelihood of the fistula returning.

What Are The Types Of Fistulotomy?

The specific type of fistulotomy depends on the location and complexity of the fistula. Here are the main types:

  • Simple Fistulotomy: This involves opening the skin over the fistula and flushing out the contents. Surgeons use this method for simple fistulas that do not involve significant surrounding tissue.
  • Seton Fistulotomy: A seton, a flexible thread, is placed through the fistula tract to help it drain gradually and heal over time. This is typically used for more complex or deeper fistulas to avoid damaging surrounding muscles, especially around the anus.
  • Advancement Flap Procedure: This type is more complex and involves creating a flap of tissue to cover the internal opening of the fistula after removing the fistula tract. It is often used when the fistula is higher within the anal canal or rectum.

LIFT (Ligation of Intersphincteric Fistula Tract) Procedure: This newer technique aims to close the internal opening and remove the infected tissue without damaging the anal sphincters. Surgeons perform this procedure from within the intersphincteric plane.

Diagnosis Before Fistulotomy

Before planning a fistulotomy, doctors need to diagnose the type and extent of the fistula accurately. They use several methods to do this:

  • Physical Examination: This is often the first step where a doctor examines the area for external signs of a fistula, such as swelling, discharge, or pain.
  • Anoscopy: A small instrument is inserted into the anus to allow the doctor to see the fistula inside the anal canal.
  • Fistulography: This involves injecting a contrast dye into the fistula tract and taking X-rays to show the path and depth of the fistula.
  • Ultrasound: An ultrasound, particularly an endoanal ultrasound, can help visualise the fistula in relation to the surrounding tissues.
  • MRI (Magnetic Resonance Imaging): MRI provides a detailed image and is particularly useful for complex or recurrent fistulas to map their course and plan surgery effectively.

What Is The Procedure For Fistulotomy?

Fistulotomy is a surgical technique used to treat anal fistulas, which are abnormal tunnels between the anal canal and the skin. This fistula drainage procedure involves several steps, each aimed at effectively resolving the issue while ensuring the patient’s comfort and recovery. Here’s what one can expect during the procedure:

  • Preparation: The patient undergoes a thorough examination, which may include imaging tests to map the fistula. Before the surgery, the patient will receive instructions on fasting and may be given antibiotics to prevent infection.
  • Anaesthesia: Fistulotomy is typically performed under general anaesthesia, meaning the patient will be asleep and pain-free during the surgery.
  • Incision: The surgeon makes a precise cut along the fistula tract, opening it up to the skin surface. This allows the surgeon to access the fistula fully.
  • Cleaning the Tract: The fistula tract is then thoroughly cleaned to remove any infection or debris. This step is crucial to prevent any further complications.
  • Flattening the Tract: The opened fistula tract is flattened out to ensure it heals from the inside out. This process helps to prevent the fistula from reforming.
  • Closure: Depending on the fistula’s location and complexity, the surgeon may leave the wound open to allow it to heal from the inside out (secondary healing) or close it with sutures.

Recovery: After the surgery, the patient will receive care instructions, including how to manage pain and keep the area clean. Follow-up appointments are crucial to monitor the healing process.

Who Is The Right Candidate For Fistulotomy?

Fistulotomy is an effective anal fistula treatment for many, but it is not suitable for everyone. The ideal candidates for this surgery are individuals who meet specific criteria. Here’s what makes someone a good candidate:

  • Simple Fistulas: Patients with simple, superficial fistulas that do not involve significant amounts of sphincter muscle are the best candidates.
  • Absence of Inflammatory Bowel Disease: Those without underlying conditions such as Crohn’s disease or ulcerative colitis are more likely to benefit from a fistulotomy, as these conditions can complicate the healing process.
  • Previous Ineffective Treatments: Patients who have not had success with less invasive treatments, such as antibiotics or drainage setons, may need a fistulotomy to resolve the fistula.
  • Good Overall Health: Being in good health with no significant medical issues helps ensure a smoother recovery and reduces the risk of complications during and after surgery.

Knowing the Risks: Candidates should understand the potential risks, such as incontinence, and discuss these thoroughly with their surgeon to make an informed decision.

What Are The Benefits Of Fistulotomy?

Fistulotomy surgery is considered the best surgery for anal fistula because it directly addresses the source of the problem with a high success rate. Here are the detailed benefits of this procedure:

  • Effective Resolution of Symptoms: Fistulotomy offers a permanent solution by completely opening up and clearing the fistula tract, which effectively alleviates painful symptoms such as discomfort and discharge.
  • High Success Rate: This procedure has a high success rate, with most patients experiencing complete healing and relief from symptoms.
  • Reduced Risk of Recurrence: By effectively removing the fistula tract, fistulotomy minimises the chance of recurrence compared to less invasive treatments that may not completely resolve the issue.
  • Minimal Invasive Nature: Although surgical, fistulotomy is less invasive than other surgical options, leading to quicker recovery times and less postoperative discomfort.
  • Preservation of Continence: When performed by experienced surgeons, fistulotomy can preserve anal sphincter function, reducing the risk of incontinence.

Short Hospital Stay: Most fistulotomy procedures are performed as day surgeries, meaning the patient can return home the same day, reducing the impact on their daily life.

How To Prepare For Fistulotomy?

Preparing for a fistulotomy involves several steps to ensure the surgery goes smoothly and to maximise the chances of a successful outcome:

  • Consultation and Assessment: Meet with your surgeon to discuss the details of the procedure and any potential risks. This is the time to address any concerns and review your medical history.
  • Preoperative Testing: Undergo necessary pre-operative tests, such as blood work and imaging studies, to help your medical team plan the procedure.
  • Medication Review: Inform your surgeon about all the medications and supplements you are taking, as some may need to be paused or adjusted before surgery.
  • Fasting: Follow your surgeon’s instructions on fasting, typically from midnight the night before your surgery.
  • Bowel Preparation: You may be required to do a bowel preparation to clear your lower intestine. This can involve taking a laxative or an enema.

Arrange for Assistance: Plan for someone to drive you home after the procedure and help around the house as you recover.

What Are The Recovery Tips and Precautions To Follow After Fistulotomy?

After undergoing fistulotomy, proper care is crucial for a swift and smooth recovery. Here’s what to expect and several recovery tips:

  • Expect Mild Discomfort: It’s normal to experience some pain after the surgery, which can be managed with prescribed painkillers.
  • Keep the Surgical Area Clean: Maintaining cleanliness around the surgery site is crucial. Gently clean the area after each bowel movement to prevent infections.
  • Monitor for Signs of Infection: Watch for increased pain, swelling, discharge, or fever. Contact your doctor if any of these symptoms occur.
  • Eat High-Fibre Foods: A high-fibre diet can help ensure soft bowel movements, which are less painful and help in the healing process.
  • Avoid Straining: Straining during bowel movements can disrupt the surgical site. Use stool softeners if recommended by your doctor.
  • Follow Up with Your Doctor: Attend all scheduled follow-up appointments so your doctor can monitor your healing progress and address any concerns.
  • Rest and Avoid Heavy Lifting: Give your body time to heal by resting and avoiding any strenuous activities or heavy lifting for the recommended period.

By adhering to these tips, you can ensure a smoother fistulotomy recovery time and reduce the risk of complications.

Potential Risks Or Complications Associated With Fistulotomy

Like any surgical procedure, fistulotomy surgery comes with potential risks and complications. Here are some of the key concerns:

  • Infection: Despite the surgical area being cleaned and treated, there is a risk of infection due to the bacteria naturally present in the anal area.
  • Bleeding: Some patients may experience significant bleeding during or after the surgery, which might require further medical intervention.
  • Incontinence: There is a risk of damage to the muscles around the anus, known as sphincters, which can lead to temporary or permanent difficulty controlling bowel movements.
  • Recurrence of Fistula: The fistula may recur if the entire tract is not completely cleared or if it heals improperly.
  • Pain: Postoperative pain is common, but it usually subsides with proper management and medications. Persistent pain might occur if the fistula recurs or if there are complications.
  • Anal Stenosis: In some cases, scarring from the surgery can lead to narrowing of the anal canal, which can cause discomfort and difficulty during bowel movements.
  • Delayed Healing: Healing times can vary, and for some, the surgical site may take longer to heal, requiring extended care and possibly additional treatments.

It’s important for patients to discuss these potential risks with their surgeon before undergoing fistulotomy surgery to understand fully what the procedure entails and how these risks apply to their specific situation.

FAQs

Is fistulotomy a major surgery?

Fistulotomy is considered a minor to moderate surgical procedure, depending on the complexity and location of the fistula. It is usually performed on an outpatient basis, meaning patients can go home the same day. The fistulotomy surgery aims to open up and clear the fistula tract to promote healing and prevent infection.

What is the procedure of fistulotomy?

The fistulotomy procedure involves making an incision over the fistula to open it. The surgeon then cleans out the tract and flattens it out to heal from the inside out. This is done under anaesthesia, and the patient usually returns home on the same day.

What is the difference between fistulotomy and fistulectomy?

The main difference is that fistulotomy involves splitting the fistula open and allowing it to heal into a flat scar, whereas fistulectomy involves completely removing the fistulous tract. Fistulotomy is generally less invasive and carries a lower risk of affecting sphincter muscles.

Can I walk after a fistulotomy?

Yes, you can walk after a fistulotomy. Walking is actually encouraged as it promotes blood flow and helps prevent complications such as blood clots. However, you should avoid strenuous activities until your doctor advises that it is safe to do so.

How much does a fistulotomy cost in India?

The cost of a fistulotomy in India can vary widely but generally ranges from ₹30,000 to ₹1,00,000. Factors affecting the price include the hospital’s location, the surgeon’s expertise, and the complexity of the procedure.

Does fistulotomy require stitches?

Fistulotomy may or may not require stitches. In many cases, the wound is left open to heal from the inside out to reduce the risk of infection. If stitches are used, they are typically placed to help close the skin over the fistula tract.

Can fistula come back after fistulotomy?

Yes, there is a chance that a fistula can recur after a fistulotomy, especially if the entire tract is not completely cleared or if it heals improperly. Recurrence rates vary depending on the specific circumstances of the surgery and the patient’s condition.

How painful is a fistulotomy?

A fistulotomy can be painful post-operatively, but the pain is generally manageable with medications prescribed by your surgeon. The level of pain can vary depending on the individual’s pain threshold and the specifics of the fistula treated.

How successful is fistulotomy?

Fistulotomy surgery is generally very successful, with success rates ranging from 85% to 95%. Success depends on the type of fistula, the skill of the surgeon, and proper post-operative care. It is effective at relieving symptoms and reducing the risk of recurrence.

How to avoid fistula recurrence?

To avoid fistula recurrence, follow your doctor’s post-operative instructions closely, which include keeping the area clean, avoiding constipation, and managing any underlying conditions like Crohn’s disease. Regular follow-ups with your doctor are crucial to monitor healing and intervene early if any issues arise.
