Fistulectomy

A precise surgical removal of abnormal tunnels between tissues, eliminating infection pathways while preserving surrounding structures through specialized techniques that promote complete healing and prevent recurrence.

A fistulectomy is a specialized surgical procedure that involves completely removing an abnormal tunnel (fistula tract) that has formed between two surfaces or organs. At our practice, we understand that dealing with a fistula can be both physically uncomfortable and emotionally distressing. That's why we're committed to providing compassionate, expert care while helping you understand each step of your treatment.

This targeted procedure effectively treats fistulas that commonly occur around the anal area (anorectal fistulas), though similar techniques are used for fistulas in other body regions. Our fistulectomy approach utilizes advanced surgical techniques to identify and completely remove the entire fistula tract while preserving sphincter function and surrounding healthy tissue. We employ careful mapping of the fistula's path, specialized instruments for precise excision, and strategic reconstruction methods that promote complete healing while minimizing recurrence risk. Our comprehensive approach includes both surgical expertise and detailed post-operative care, resulting in effective, lasting elimination of the fistula while maximizing your comfort and functional outcomes.

Indications & Symptoms

You may need a fistulectomy if you experience:

  • Persistent drainage or discharge from an opening near the anus

  • Recurrent abscesses in the perianal area

  • Pain or discomfort in the anal region, especially during bowel movements

  • Swelling, redness, or tenderness around the anus

  • Itching or irritation in the perianal skin

  • Bleeding from an external opening near the anus

  • Failed previous treatments for anorectal fistula

  • Visible external opening with periodic drainage

  • Discomfort during sitting or physical activities

  • Perianal infection that recurs despite antibiotic treatment

  • Fistula confirmed by imaging studies (MRI, endoanal ultrasound)

  • Perianal Crohn's disease with fistula formation

  • Fistula development following anorectal abscess drainage

  • Fistula causing hygiene difficulties or soiling of undergarments

  • Pain or swelling that cycles between improvement and worsening

Treatment Approach

Our approach to fistulectomy combines precision with individualized care. The procedure begins with comprehensive evaluation, often including specialized imaging such as endoanal ultrasound or MRI to fully map the fistula's path and identify its internal opening and any secondary branches. What sets us apart is our expertise in selecting the most appropriate surgical technique based on your specific fistula type, location, and complexity, while prioritizing preservation of sphincter function and continence.

For straightforward fistulas (intersphincteric or low transsphincteric), we perform traditional fistulectomy, which involves complete excision of the entire fistula tract from the internal to external opening. This approach offers excellent healing rates and low recurrence by removing all infected tissue, though healing time is longer than some other techniques. For complex or high fistulas that involve significant sphincter muscle, we may employ modified approaches such as staged fistulectomy, mucosal advancement flap technique, or LIFT procedure (ligation of intersphincteric fistula tract) to maximize sphincter preservation while effectively treating the fistula.

Our distinctive approach includes meticulous identification of the internal opening—a critical step in preventing recurrence—and the use of advanced surgical tools that allow precise tissue removal while minimizing damage to surrounding structures. For patients with Crohn's disease or other complicating factors, we coordinate closely with gastroenterologists to optimize medical management alongside surgical intervention. Throughout the process, we employ specialized wound care techniques including properly designed packing methods and strategic drainage to promote healing from the inside out, preventing premature closure of the external wound before the deeper tissues have healed.

This comprehensive approach ensures not only technical excellence during your procedure but also optimal post-operative management, giving you the best chance for complete healing and minimized recurrence risk while preserving normal bowel function and continence.

Recovery Guidance

Immediate Post-Procedure (1-7 days)

  • Expect moderate to significant discomfort for the first several days

  • Receive specialized pain management including both oral medications and topical treatments

  • Begin sitz baths (warm water soaks) 24 hours after surgery, continuing 2-3 times daily

  • Learn proper wound care techniques, including cleaning after bowel movements

  • Maintain properly placed packing if used (may be removed at first post-op visit)

  • Take prescribed antibiotics if indicated to prevent infection

  • Use stool softeners and fiber supplements to avoid constipation

  • Expect some bleeding or drainage from the surgical site, typically decreasing over time

  • Rest and avoid prolonged sitting or strenuous activities

  • Keep the surgical area clean and dry between sitz baths

  • Manage pain with prescribed medications taken on schedule

  • Prepare for your first follow-up visit, typically scheduled 5-7 days after surgery

Short-Term Recovery (1-4 weeks)

  • Attend your follow-up appointment where the surgeon will assess the healing progress

  • Continue sitz baths after bowel movements and 2-3 times daily

  • Maintain a high-fiber diet and adequate fluid intake to prevent constipation

  • Monitor the wound for proper healing from the depth outward

  • Expect ongoing drainage that gradually decreases as healing progresses

  • Recognize that discomfort gradually improves, though complete comfort may take weeks

  • Avoid heavy lifting (nothing over 10 pounds) for at least 2-3 weeks

  • Return to work based on your surgeon's recommendation and job requirements:

    • Desk jobs: typically 1-2 weeks

    • More physical jobs: may require 3-4 weeks

  • Modify activities to accommodate healing and avoid undue pressure on the surgical area

  • Continue prescribed wound care regimen, which may include specialized cleansing or packing

  • Begin gentle walking for exercise as comfort allows

  • Report any signs of infection or significant increase in pain promptly

  • Understand that healing occurs from the inside out, requiring patience during this process

Long-Term Recovery (1-3 months)

  • Continue attending follow-up appointments to monitor healing progress

  • Recognize that complete healing of a fistulectomy wound typically takes 4-8 weeks depending on the size

  • Gradually increase physical activities as the wound heals and comfort improves

  • Resume normal activities, including more strenuous exercise, as cleared by your surgeon

  • Monitor for any signs of recurrence, including new drainage or pain

  • Maintain dietary habits that promote soft, regular bowel movements

  • Observe the gradual closing of the wound from the base upward

  • Expect significant improvement in original symptoms as healing progresses

  • Begin transitioning from specific wound care to normal hygiene routines

  • Address any concerns about bowel function or discomfort with your healthcare team

  • Notice continued improvement in comfort during sitting and daily activities

  • Understand that some patients may require additional procedures for complete healing

  • Follow any specific recommendations for patients with underlying conditions like Crohn's disease

Long-Term Expectations

  • Complete healing typically occurs within 2-3 months for most fistulectomy patients

  • Expect a small, well-healed depression or scar at the surgical site

  • Recurrence rates vary based on fistula complexity:

    • Simple fistulas: 5-10% recurrence

    • Complex fistulas: 10-30% recurrence

    • Crohn's-related fistulas: higher recurrence rates without optimal medical management

  • Preservation of normal bowel control and sphincter function in most patients

  • Return to all normal activities without restrictions once healing is complete

  • Need for ongoing management of underlying conditions that may have contributed to fistula formation

  • Implement preventive measures to reduce recurrence risk:

    • Proper perianal hygiene

    • Management of any underlying conditions (Crohn's disease, etc.)

    • Proper fiber intake and hydration

    • Prompt attention to any perianal infections or abscesses

  • Annual follow-up is recommended for the first few years to monitor for recurrence

  • Excellent long-term quality of life following successful healing

  • Most patients experience complete resolution of drainage, pain, and discomfort

  • Rare cases may require additional treatments for residual symptoms

At 50, I now have a life I had only dreamed of a year before. My body tells me if I am done eating. This surgery is a tool that I have used to the fullest. It is not an easy way out. It still took work. But I honestly know that I would not be living this amazing new life if I didn’t step forward to embrace this life-saving surgery.
