Fistula Surgical Removal

A fistulectomy is a surgical procedure to remove a fistula, which is an abnormal tunnel-like connection that can form between two internal organs or between an internal organ and the skin however they are more commonly occur in the anorectal region, meaning they form between the end of the digestive tract (the anus or rectum) and the skin around it. This can happen when an infection near the anus creates a tunnel connecting the inside of the anus to the skin outside, leading to discomfort and potential complications if not treated.

While a fistulectomy is effective, the procedure’s potential impact on sphincter function necessitates careful patient selection and consideration of alternative treatments to ensure optimal outcomes.

Why Cuba

In Cuba, fistulectomy procedures are performed by experienced surgeons who emphasize patient safety, effective symptom relief, and favorable long-term outcomes. The country’s healthcare system is recognized for its high-quality medical services, offering comprehensive preoperative assessments, advanced surgical techniques, and attentive postoperative care to ensure smooth recovery and minimize complications. Surgeons adopt a personalized approach, selecting the most appropriate and minimally invasive techniques whenever possible to enhance patient comfort, reduce postoperative discomfort, and expedite healing for those undergoing fistula removal.

Causes of Fistulas

Fistulas can arise due to various factors, including:

• Infection or Abscess: An untreated or inadequately drained abscess can lead to fistula development.
• Inflammatory Conditions: Diseases like Crohn’s disease can cause chronic inflammation, increasing the risk of fistula formation.
• Trauma or Surgery: Injuries or surgical interventions in the anorectal area may result in fistulas.

Types and Classification of Fistulas

Fistulas are categorized based on their location and complexity:

• Simple Fistulas: Involve minimal muscle and have a straightforward tract.
• Complex Fistulas: Involve significant muscle mass, may have multiple tracts, and are often associated with conditions like Crohn’s disease.

Symptoms of Fistulas

Common symptoms include:

• Persistent pain or discomfort in the anal area.
• Recurrent abscesses.
• Discharge of pus or blood.
• Irritation or swelling around the anus.

Pre-Surgical Diagnosis

Accurate diagnosis of fistulas is essential for effective treatment, involving a combination of clinical evaluation and imaging studies:

• Clinical Evaluation: A thorough physical examination is the first step in diagnosing a fistula. Assessment of the affected area to identify external openings, areas of tenderness, or signs of infection is conducted. This assessment helps determine the fistula’s location, size, and complexity, guiding further diagnostic steps.

• Imaging Studies: Advanced imaging techniques provide detailed visualization of the fistula tract and surrounding structures:

• Magnetic Resonance Imaging (MRI): MRI offers high-resolution images, making it particularly useful for complex fistulas or those involving intricate anatomy. It helps delineate the fistula’s course, identify any abscesses, and assess involvement of adjacent organs or tissues.

• Ultrasound: Especially valuable in anorectal fistulas, ultrasound, including endoanal or transperineal approaches, allows real-time assessment of the fistula’s path and any associated fluid collections. It’s a non-invasive, readily available modality that aids in both diagnosis and treatment planning.

• Computed Tomography (CT) Scan: CT scans can detect fistulas, particularly those related to the gastrointestinal tract, by providing cross-sectional images that reveal the presence of abnormal connections or abscesses.

Surgical Options for Fistula

Surgical intervention for a fistula is considered when non-surgical management is ineffective or when complications arise. While some fistulas may be managed with medications, drainage, or lifestyle modifications, persistent or severe cases typically require surgery for long-term resolution. Surgery is recommended in the following situations:

• Significant Symptoms or Recurrent Infections: A fistula causes chronic pain, persistent drainage, or repeated infections require intervention.

• Risk of Complications: Untreated fistulas can develop secondary infections leading to the formation of abscesses (pockets of pus), which can spread bacteria and cause systemic infections.

• Failure of Non-Surgical Treatments: When antibiotics, wound care, and other conservative approaches fail to resolve a fistula, surgery is often the only viable option. Long-term fistulas that fail to heal on their own may become more complex, making early surgical intervention crucial for preventing further complications.

The choice of surgery depends on multiple factors, including:

• The complexity and depth of the fistula.
• The involvement of surrounding muscles or tissues.
• The patient’s overall health and risk factors.

There are several surgical techniques used to treat fistulas, depending on their location, complexity, and severity. Some procedures involve traditional open surgery, while others use minimally invasive techniques for faster recovery and reduced complications.

Traditional Fistulectomy (Open Surgery)

• This is a complete excision of the fistula tract, removing all diseased tissue to prevent recurrence. The procedure may involve cutting into deep tissue layers, depending on the fistula’s location and complexity.
• This procedure is mostly carried out for complex, deep, or chronic fistulas.
• May require wound packing or secondary closure techniques.

Fistulotomy (For Simple Fistula)

• This procedure involves cutting open the fistula tract and flattening it so it can heal from the inside out. It is commonly used for low-risk, superficial fistulas that do not involve the anal sphincter.
• Simple fistulotomy has a lower risk of infection compared to complete excision.
• Risk of incontinence if the sphincter muscle is affected.

Seton Placement

• This procedure places a seton (surgical thread or rubber band) inside the fistula tract to allow gradual drainage and healing without cutting the surrounding muscles. The seton remains in place for weeks or months, reducing the risk of incontinence in high-risk cases.
• This procedure is typically carried out for high-risk patients who cannot undergo major surgery.
• Requires multiple procedures or adjustments over time.
