Post-anal fistula surgery


Dr.
Ke: Six months ago, I felt two fistulas, with only one internal opening and no external opening.
There was a bulge, and when I touched it, I could feel pus, but it never ruptured.
I could feel the internal opening with my finger when I inserted it into my anus.
Last week, I was hospitalized for a fistula excision surgery, but in the last two days, I discovered that there is still one fistula that was not removed! Today, during my follow-up appointment, I asked the doctor about it.
The doctor did not say it was a surgical failure; he only mentioned that the unremoved fistula was to protect the sphincter.
However, I found information online stating that if a fistula is not completely excised, the recurrence rate is extremely high! There was no discussion about this with the doctor before the surgery, and I assumed both would be removed.
Today, I confirmed with the doctor that the unremoved one is a branch canal, with no internal or external openings.
He only told me that the main canal and internal opening were excised, and if I am not uncomfortable, I do not need to worry.

I would like to ask Dr.
Ke:
1.
Could it be that my branch canal is high-level, which is why the surgeon did not address it? Now that I still have one branch canal in my body, is the recurrence rate high? It feels like a ticking bomb, and I am very anxious.

2.
Based on your clinical observations, was my surgeon's approach reasonable?
3.
It has been a week since the surgery; can I use body wash while showering? I am concerned that the body wash water might splash onto the wound.

4.
If it is confirmed that the removed one is a high-level anal fistula, would your approach also be to excise it directly? I read that you mentioned traditional methods for branch canals, but I couldn't find more surgical methods for high-level fistulas online.

5.
I am thinking, if the internal opening is removed and heals well, then the remaining fistula should not be exposed to bacteria, right? Can I understand it this way? The unremoved fistula, without internal and external openings, wouldn’t it create an internal opening on its own, would it? I am very scared.
Thank you, Dr.
Ke, for your thoughtful responses, and I wish you a pleasant workday.

1.
You need to ask your attending physician for this information, as they cannot provide an answer without a personal examination.
There is always a possibility of recurrence with an unexcised fistula.

2.
Yes, it is possible.

3.
High anal fistulas can be treated with endoscopic fistula surgery by physicians, but there is currently no consensus in the academic community regarding the outcomes.

4.
In theory, this is correct, but the healing condition of the internal opening is unpredictable.

Post-surgery concerns regarding anal fistula treatment can be quite complex, especially when it involves the presence of multiple fistulas and the potential for recurrence. Here’s a comprehensive overview of your concerns based on the situation you described.

1. Understanding the Remaining Fistula: It’s understandable to feel anxious about the remaining fistula, especially if it’s perceived as a “time bomb.” The fact that your surgeon mentioned that the remaining fistula is a “branch” without an internal or external opening suggests that it may not pose an immediate risk. However, the concern about recurrence is valid. Fistulas can be tricky; if they are not completely excised, there is a chance they can recur. The recurrence rate can vary based on the complexity of the fistula and the surgical technique used. High-level fistulas, which are deeper and may involve the anal sphincter, often require more careful management to avoid complications.

2. Surgical Reasoning: The decision to leave a branch of the fistula intact to protect the anal sphincter is a common practice. The anal sphincter is crucial for maintaining continence, and any damage to it can lead to significant complications, including incontinence. Your surgeon’s approach may have been to minimize the risk of damaging this critical structure. In clinical practice, it’s not uncommon for surgeons to prioritize the preservation of function over the complete removal of a fistula, especially if the remaining part is not causing symptoms.

3. Post-operative Care: After a week of surgery, it’s generally advisable to follow your surgeon’s post-operative care instructions closely. Regarding bathing, using mild soap or body wash is typically acceptable, but care should be taken to avoid direct contact with the surgical site. It’s best to gently clean the area with water and avoid any products that could irritate the skin or the surgical site until it has fully healed. If you have concerns about water splashing onto the wound, consider using a handheld showerhead or taking sponge baths until you feel more comfortable.

4. Management of High-Level Fistulas: If it is determined that the remaining fistula is indeed a high-level fistula, the management may vary. Surgical options can include additional procedures to excise the fistula or other techniques such as seton placement, which allows for gradual drainage and healing. The approach will depend on the specific anatomy of the fistula and the potential risks involved. It’s crucial to have a detailed discussion with your surgeon about the best course of action based on your individual case.

5. Understanding Fistula Dynamics: Your concern about the remaining fistula not developing an internal opening is valid. Fistulas typically form due to infection or inflammation, and if the remaining branch is not exposed to bacteria (due to the absence of an internal opening), it may not pose a significant risk. However, it’s essential to monitor any changes in symptoms. If you notice any signs of infection or changes in the area, it’s important to contact your healthcare provider promptly.

In conclusion, while it’s natural to feel anxious about the remaining fistula, it’s essential to trust your surgeon’s expertise and maintain open communication with them. Regular follow-ups and monitoring are crucial in managing your condition effectively. If you have ongoing concerns, don’t hesitate to seek a second opinion or ask for a more detailed explanation of your treatment plan. Your health and peace of mind are paramount, and understanding your condition is a vital part of the healing process.
