Post-Surgery Care for Anal Fistula: Common Concerns and Solutions - Surgery

Anal fistula


Hello, Doctor.

1.
I had anal fistula surgery on March 16, and the wound size is approximately 2x21 cm.
It's been almost a week, but there is still fecal matter coming out of the wound.
Is this normal?
2.
The doctor prescribed a stool softener, but I have been experiencing diarrhea every day.
Should I reduce the dosage?
3.
After I have a bowel movement and rinse with warm water, the nerve in that part of my buttocks still hurts a lot, and the wound is extremely painful after a bowel movement.
It doesn't hurt when I don't have a bowel movement.

4.
The doctor suggested using a transparent membrane powder but didn't explain how to use it.
I found online that it forms a layer, so won't that cause feces to get stuck in the wound during a bowel movement? Can you please clarify the correct usage?
5.
I see that everyone else is doing sitz baths, but the doctor told me to just rinse with running water.
What is the difference?

1.
If the wound is larger, it is indeed possible for this phenomenon to occur; if the amount is not significant, it is not a concern.

2.
If the stool is too soft, the dosage should be reduced or the medication should be stopped, as this may also be a cause of issue one.

3.
Normal.

4.
Personally, I do not recommend using a bidet; a warm water sitz bath is sufficient.

5.
Sitz baths can cause a reflex relaxation of the sphincter, making the wound less painful.
Using a handheld shower may cause anal contraction due to irritation.
I personally recommend warm water sitz baths, and the water temperature should not be too high.

Post-surgery care for anal fistula can be quite challenging, and it's important to address your concerns comprehensively. Here’s a breakdown of your questions and some additional insights based on medical knowledge.

1. Is it normal for stool to come out of the wound?
After anal fistula surgery, it is not uncommon for some stool to leak from the surgical site, especially in the early days post-operation. This can happen if the fistula has not completely healed or if there is still some connection between the rectum and the external opening. However, if you notice significant leakage or if the wound appears to be worsening, it’s essential to consult your surgeon. They may need to evaluate the healing process and determine if further intervention is necessary.

2. Should I reduce the dosage of the stool softener?
If you are experiencing diarrhea from the stool softener, it may be wise to reduce the dosage or discuss alternative options with your doctor. Stool softeners are intended to ease bowel movements, but they should not cause excessive diarrhea. Maintaining a balance is crucial, as constipation can also lead to straining, which can be painful and detrimental to the healing process.

3. Why does the wound hurt after bowel movements?
Pain after bowel movements is a common experience following anal fistula surgery. This pain can be due to several factors, including inflammation, sensitivity of the surgical site, or even muscle spasms in the anal area. If the pain is severe or worsening, it is important to communicate this to your healthcare provider. They may recommend pain management strategies, such as topical anesthetics or pain relief medications.

4. How to use the protective powder correctly?
The protective powder, often referred to as a barrier powder, is used to create a protective layer over the wound to prevent irritation from stool. To use it correctly, first clean the area gently with warm water and pat it dry. Then, apply a thin layer of the powder to the affected area. It should form a barrier that helps absorb moisture and protect the skin from irritation. However, it’s crucial to ensure that the powder does not obstruct the healing process. If you are concerned about bowel movements getting stuck, you may want to consult your doctor for specific recommendations tailored to your situation.

5. What is the difference between sitz baths and using running water?
Sitz baths involve sitting in warm water to soothe the anal area, which can help reduce pain and promote healing. They are often recommended for their benefits in increasing blood flow to the area and relaxing the muscles. On the other hand, using running water can also be effective for cleaning the area after bowel movements, but it may not provide the same level of soothing relief as a sitz bath. Your doctor may have specific reasons for recommending running water, such as avoiding prolonged exposure to moisture that could lead to skin irritation. If you feel that a sitz bath would provide more comfort, discuss this with your healthcare provider.


Additional Recommendations:
- Dietary Considerations: Focus on a high-fiber diet to promote regular bowel movements without straining. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Staying hydrated is also crucial.

- Hygiene Practices: Maintain good hygiene by gently cleaning the area after bowel movements. Avoid harsh soaps or scrubbing, as this can irritate the skin.

- Follow-Up Appointments: Regular follow-ups with your surgeon are essential to monitor the healing process and address any complications early on.

In conclusion, while some discomfort and complications can be expected after anal fistula surgery, it’s vital to communicate openly with your healthcare provider about your symptoms. They can provide tailored advice and interventions to ensure a smoother recovery process.
