Fistula-in-ano is a surgical condition characterized by an abnormal tract or tunnel that forms between the anal canal and the skin surrounding the anus. It can lead to discomfort, pain, and recurrent infections. Surgical intervention is necessary to manage fistula-in-ano effectively. In this blog, we will explore the various surgical approaches used to treat this condition, aiming to provide a comprehensive understanding of the treatment options available. There is no single best surgery for Fistula-in-Ano that works for all. The decision has to be carefully taken.


Understanding Fistula-in-Ano


Before delving into the surgical approaches, it's essential to understand the anatomy and etiology of fistula-in-ano. This condition typically develops as a result of an infection in the anal glands, leading to the formation of an abscess. If left untreated, the abscess can evolve into a fistula, a tunnel-like structure that connects the abscess cavity to the skin's surface. Fistulas can be complex, branching out in various directions, making them challenging to treat.


Surgical Approaches for Fistula-in-Ano


1. Fistulotomy:

- Fistulotomy is a common and straightforward surgical procedure used to treat simple, low-lying fistulas. In this approach, the surgeon makes an incision along the fistula tract, completely opening it to allow proper drainage. The wound is left open to heal gradually from the inside out. Fistulotomy offers a high success rate for uncomplicated cases but may not be suitable for complex or high fistulas.


2. Fistulectomy / Coring:


3. Seton Placement:

- Seton placement is a temporary treatment option for complex or high fistulas. A seton is a piece of material, such as a suture or rubber band, that is passed through the fistula tract and left in place - called the draining seton. This helps in gradual drainage and allows the tract to mature or scar down over time. Once the fistula is well-established, it can be treated with a more definitive procedure.


4. LIFT Procedure (Ligation of Inter-sphincteric Fistula Tract):

- The LIFT procedure is a relatively newer technique used for treating high inter-sphincteric fistulas. It involves ligating or tying off the internal opening of the fistula tract and then excising the tract between the internal and external openings. This approach preserves the anal sphincter function and has shown promising results for certain types of fistulas.


5. Fibrin Glue Injection:

It is a non-surgical option for specific fistulas, primarily those with simple anatomy. This procedure involves injecting a special medical adhesive into the fistula tract, which promotes healing and closure. However, the success rate is lower compared to other surgical methods and may require multiple sessions.


Although a tempting option due to avoidance of need of Surgery. The failure rates can be as high as 50%. And the cost & animal origin of the plug is inhibitory to its wide spread use.


7: Advancement Flap Repair:

Advancement flap repair is a surgical technique used for complex fistulas that have a high risk of incontinence if treated with other methods. In this procedure, a flap of healthy tissue is created and advanced over the internal opening of the fistula, effectively closing it off. This technique preserves sphincter function but may have a longer recovery time.


8. VAAFT:

Video Assisted Ablation of the Fistulous Tract is a minimally invasive technique for ablation of the tract using energy & a special instrument to scrape the granulation tissue. The internal opening is then closed with sutures or a proximal fistulotomy is done.


9. LASER Ablation

In this technique Laser fiber is introduced into the fistulous tract to destroy the granulation tissue which is then scraped and the internal opening is closed with suture or proximal Fistulotomy is performed.



Conclusion


Fistula-in-ano is a challenging condition that can significantly impact a patient's quality of life. The choice of surgical approach depends on various factors, including the type and complexity of the fistula, as well as the patient's overall health and preferences.


It is crucial for individuals experiencing symptoms of fistula-in-ano to consult with an expert & qualified colorectal surgeon who can assess their condition and recommend the most appropriate treatment option.

While surgical intervention is often necessary, the goal is to balance effective management of the fistula with preserving anal sphincter function to maintain bowel control (continence). Advances in surgical techniques continue to improve outcomes, offering hope for a better quality of life for those affected by this condition.
