Fistula surgery


Hello Doctor, I am a patient from Hong Kong.
There are very few relevant posts and answers on Hong Kong websites, so I hope to seek professional advice from you to alleviate my concerns.
I have recently been diagnosed with an anal fistula.
After a digital rectal examination, the doctor indicated that it is a low anal fistula (with an external opening discharging pus).
Since the waiting time for surgery in public hospitals in Hong Kong is three months or more, I have the following questions that I hope you can answer:
1.
Is there a possibility of worsening if I wait for three months? For example, could more fistulas develop?
2.
Will I be unable to have stitches after the surgery?
3.
Will bowel movements be very painful after the surgery?
4.
How does the doctor determine that I only have one fistula? The diagnostic process took less than ten minutes, and it didn't feel very thorough.
Would it be better to have an X-ray for a more accurate assessment? Thank you!

1.
An anal fistula is a chronic infectious disease, and if it experiences repeated infections over a long period, it may develop into a complex fistula; however, waiting for three months will not have a significant impact.

2.
After anal fistula surgery, to prevent recurrence, the wound is intentionally left open and not sutured, which results in a longer recovery time.

3.
Pain is usually more severe one week post-surgery, but most patients report a decrease in pain after two weeks.

4.
X-rays cannot diagnose anal fistulas; in the United States, magnetic resonance imaging (MRI) is used for diagnosis.
However, due to the high cost, we also rely on digital examination for assessment, and MRI is only considered for complex fistulas.

Understanding fistula surgery and addressing patient concerns is crucial for ensuring that patients feel informed and prepared for their treatment. Fistulas, particularly anal fistulas, can be a source of significant discomfort and anxiety for patients. Here, I will address your questions based on medical knowledge and common practices regarding anal fistula management.

1. Risk of Deterioration While Waiting for Surgery: It is understandable to be concerned about the potential for worsening of your condition while waiting for surgery. Generally, anal fistulas can remain stable for a period, but there is a risk that they may become more complicated over time. This could include the development of additional fistulous tracts or increased infection. If you notice any changes in symptoms, such as increased pain, swelling, or discharge, it is essential to contact your healthcare provider promptly. They may be able to expedite your surgery or provide interim management strategies to alleviate discomfort.

2. Surgical Closure and Stitching: The approach to surgery for anal fistulas can vary based on the complexity of the fistula and the surgeon's preference. In many cases, the fistula is excised, and the area is allowed to heal naturally without stitches. This method, known as fistulotomy, is often preferred because it allows for better drainage and healing. However, in some cases, particularly with more complex fistulas, sutures may be used to close the surgical site. Your surgeon will discuss the best approach for your specific situation.

3. Postoperative Pain During Bowel Movements: It is common for patients to experience some discomfort after fistula surgery, especially during bowel movements. The level of pain can vary significantly from person to person. Many surgeons recommend a high-fiber diet, adequate hydration, and possibly stool softeners to minimize straining during bowel movements, which can help reduce pain. Additionally, warm sitz baths can provide relief and promote healing. Your surgeon will provide specific postoperative care instructions tailored to your needs.

4. Diagnosis and Imaging: The diagnosis of an anal fistula is typically made through a physical examination, including a digital rectal exam. While this can be sufficient for many cases, if there is uncertainty about the complexity of the fistula or if multiple tracts are suspected, imaging studies such as an MRI or an endoanal ultrasound may be recommended. These imaging techniques can provide a more detailed view of the fistula's anatomy and help guide surgical planning. If you feel that your examination was not thorough enough, it is reasonable to discuss your concerns with your surgeon and inquire about the possibility of further imaging.

In conclusion, while waiting for surgery can be anxiety-inducing, it is essential to maintain open communication with your healthcare provider. They can offer guidance on managing symptoms and monitoring your condition. Understanding the surgical process and what to expect can help alleviate some of your concerns. If you have further questions or if your symptoms change, do not hesitate to reach out to your healthcare team for assistance. Your health and comfort are paramount, and they are there to support you through this process.
