Postoperative soreness is common after anal fistula surgery?


Hello Doctor, I underwent anal fistula surgery on September 5th of this year.
Although the surgeon mentioned that the location of my fistula was difficult to locate, they managed to address it based on their experience.
I have had several follow-up visits, and the doctor assured me that everything was fine, but I have been recovering slowly due to granulation tissue formation.
Currently, there is no wound, but the tissue has not fully healed, and I can see a small portion missing from the anal area.
There is no significant discharge.

Two weeks ago, I had a bowel movement that was quite large and hard, and I am unsure why.
Now, my anus feels very sore, and I experience discomfort while walking.
It feels like my anus is very tight, and occasionally I have the urge to have a bowel movement, but I do not feel anything when I am sleeping or just waking up.
After walking a few times, I start to feel sore, but there is no pain.

Doctor, could this be related to the fact that the tissue in the affected area has not fully healed? What should I do? Recently, I have been unable to visit the clinic because my insurance is still under review.

Hello, based on your description, you have undergone surgical treatment for an anal fistula, and the wound has healed.
Recently, you have been experiencing soreness and other symptoms in the anal area, which may be due to scar tissue following the healing of the wound.
You might consider warm sitz baths to promote local circulation and alleviate the symptoms.

More Info


After undergoing anal fistula surgery, it's not uncommon to experience a range of symptoms during the recovery process. Your description of the situation indicates that while you have made some progress—such as the absence of an open wound—there are still concerns regarding discomfort and the healing of the tissue.

Firstly, the presence of granulation tissue, which you mentioned, is a normal part of the healing process. This tissue can sometimes take longer to mature and may not appear as healthy or fully formed as surrounding tissues. The fact that you can see a small area missing from the anal sphincter (the "菊花缺一小角") suggests that the surgical site is still in the process of healing. It's important to note that the anal area is sensitive and can take time to fully recover, especially after surgery.

The discomfort you're experiencing, particularly after having a hard bowel movement, could be attributed to several factors:
1. Tissue Sensitivity: The area around the anus is highly sensitive, and any surgical intervention can lead to increased sensitivity during the healing phase. The tightness and soreness you feel may be a result of the surgical site still adapting and healing.

2. Bowel Movements: Hard stools can cause strain during bowel movements, which can lead to discomfort, especially in a recently operated area. It's crucial to maintain soft stools to minimize strain. Consider increasing your fiber intake through fruits, vegetables, and whole grains, and staying well-hydrated. Over-the-counter stool softeners may also be beneficial.

3. Muscle Tension: The feeling of tightness or the urge to contract the anal sphincter could be a response to discomfort or anxiety about bowel movements. This can create a cycle of tension that exacerbates the sensation of pain or discomfort. Relaxation techniques, such as deep breathing or pelvic floor relaxation exercises, may help alleviate some of this tension.

4. Post-Surgical Changes: After surgery, the anatomy of the area may change slightly, which can lead to new sensations or discomfort as your body adjusts. This is often temporary, but if it persists, it may require further evaluation.

Given that you are currently unable to visit a clinic due to insurance issues, here are some suggestions to help manage your symptoms at home:
- Warm Baths: Soaking in warm water can help soothe the area and promote relaxation of the anal sphincter. This can also aid in reducing discomfort after bowel movements.

- Topical Treatments: Over-the-counter creams or ointments designed for anal discomfort may provide relief. Look for products that contain soothing ingredients like witch hazel or aloe vera.

- Dietary Adjustments: As mentioned, focus on a high-fiber diet and adequate hydration to prevent hard stools. If necessary, consult with a nutritionist for tailored advice.

- Gentle Exercise: Light walking can promote circulation and help with overall recovery, but be mindful of your body's signals and avoid overexertion.

- Monitoring Symptoms: Keep track of your symptoms, including any changes in pain levels, bowel habits, or any new sensations. If your condition worsens or if you experience significant pain, bleeding, or other concerning symptoms, it’s essential to seek medical attention as soon as possible.

In conclusion, while some discomfort and tightness are expected during the recovery from anal fistula surgery, it’s crucial to manage your bowel health and monitor your symptoms closely. If your situation does not improve or worsens, it would be advisable to consult a healthcare professional when possible. Your health and comfort are paramount, and timely medical advice can help ensure a smoother recovery.
