More than a year after anal fistula surgery..?


Hello, doctor.
I apologize for interrupting you during your busy schedule.
I would like to ask you about my anal fistula.
I had surgery for it in early January last year, and it has been a year and a half since then.
During this time, I have had a slight swelling at the larger area of the fistula wound.
The doctor mentioned that it could be a keloid-like condition, and it has been intermittently itchy.
When I returned for a follow-up, the doctor said there was nothing to worry about and that it was healing well.
However, the swelling has not diminished and looks like a scar, but I can feel a thin, elongated canal extending from it, which seems to have been there since the surgery.
Recently, this swelling has started to hurt.

1.
Is it possible that the fistula has recurred?
2.
Does a fistula have a fixed shape when it forms an opening, or is it variable?
3.
If an opening forms, does it always result in pus drainage?
4.
Is it possible for an opening to form without any pus drainage?

Post-surgery complications related to anal fistula surgery can be a source of significant concern for patients, particularly when symptoms persist or new issues arise. In your case, it seems that you have been experiencing a persistent lump at the surgical site, which raises several important questions regarding the potential for recurrence, the nature of the fistula, and the implications for your recovery.

1. Possibility of Recurrence: The presence of a lump at the site of your previous anal fistula surgery could indeed suggest a recurrence of the fistula. Fistulas can sometimes recur if the initial surgery did not completely remove the entire tract or if there was an underlying condition that predisposed you to develop another fistula. The fact that you are experiencing pain in the area is also a concerning sign, as this could indicate inflammation or infection. It is crucial to follow up with your surgeon or a colorectal specialist to evaluate the lump and determine whether it is a recurrence of the fistula or a different issue, such as a scar tissue formation or a cyst.

2. Formation of the Fistula Opening: Fistulas can vary significantly in their anatomy. Some fistulas have a fixed shape and opening, while others may be more irregular. The configuration of a fistula can depend on various factors, including the underlying cause (e.g., Crohn's disease, abscess, etc.) and the individual anatomy of the patient. If a fistula does recur, it may not necessarily have the same characteristics as the original one.

3. Discharge from the Fistula: If a fistula has formed an opening, it is common for it to discharge pus or other fluids. However, this is not an absolute rule. Some fistulas may have an opening that does not produce any discharge, especially if the tract is not actively infected or if it has become obstructed. The presence or absence of discharge can vary based on the fistula's condition and whether there is any ongoing inflammation or infection.

4. Absence of Discharge: It is indeed possible for a fistula to have an opening without any discharge. This can occur if the fistula is not currently infected or if the body has formed a closure at the opening, which can happen in some cases. However, even in the absence of discharge, the presence of pain or discomfort should not be ignored, as it may indicate that the fistula is still active or that there is another underlying issue.

In summary, it is essential to have a thorough evaluation by a healthcare professional who specializes in colorectal surgery. They may recommend imaging studies, such as an MRI or ultrasound, to assess the fistula's anatomy and determine the best course of action. Treatment options may include further surgical intervention if a recurrence is confirmed or other management strategies if the lump is determined to be scar tissue or another benign condition.
Additionally, managing any discomfort or pain you are experiencing is crucial for your overall well-being. If you have concerns about the healing process or the appearance of the surgical site, do not hesitate to reach out to your healthcare provider for guidance and support. Regular follow-ups and open communication with your medical team can help ensure that any complications are addressed promptly and effectively.
