Symptoms: Is It an Anal Fistula or Something Else? - Surgery

Are these symptoms related to the anal canal?


Hello Dr.
Ke: About two to three months ago, I experienced diarrhea, which, combined with my pre-existing internal hemorrhoids, led to an anal fissure with bleeding.
For the past two to three months, I have been applying medication and improving my bowel habits, having regular bowel movements twice a day (morning and evening), and I also take warm sitz baths.
However, I feel that my symptoms have not improved, and there is a small growth at the anal opening.
A month ago, touching it was very painful, but currently, I still experience some pain during bowel movements, and there is also pain when the anal sphincter tightens.
While sitting, I feel some swelling and pain as well, but there is no discharge or signs of a fistula.
The pain has persisted for about three months now, and I am unsure if these symptoms indicate a fistula.
Thank you.

Chronic anal pain following long-term diarrhea is usually caused by anal fissures rather than fistulas.
If the pain persists, it is important to consult a physician for diagnosis and treatment; otherwise, if a fistula is present, there may be complications due to infection.
However, a definitive diagnosis cannot be made without a personal examination by a physician.

Based on the symptoms and history you've provided, it sounds like you may be experiencing complications related to your existing internal hemorrhoids, possibly leading to an anal fissure or even an anal fistula. Let's break down the symptoms and what they might indicate.


Symptoms Analysis
1. Bleeding and Pain: The initial bleeding and pain you experienced after diarrhea could be attributed to an anal fissure, which is a tear in the anal lining often caused by passing hard stools or straining during bowel movements. This is common in individuals with a history of hemorrhoids.

2. Persistent Symptoms: The fact that you have been experiencing symptoms for two to three months, despite treatment and improved bowel habits, is concerning. The presence of a "small thing" at the anal opening, along with ongoing pain during bowel movements and when the anal sphincter tightens, suggests that there may be more than just a fissure or hemorrhoids at play.

3. No Discharge: The absence of pus or discharge is a good sign, as it may indicate that there is no active infection. However, the pain and swelling you describe, especially when sitting, could suggest inflammation or irritation in the anal area.


Possible Conditions
- Anal Fissure: If the pain is sharp during bowel movements and there is occasional bleeding, this could still be an anal fissure. Fissures can be quite painful and may take time to heal, especially if the underlying cause (like constipation or diarrhea) persists.

- Anal Fistula: An anal fistula is an abnormal connection between the anal canal and the skin. It can develop after an abscess or as a complication of a fissure. Symptoms typically include pain, swelling, and sometimes discharge. However, since you mentioned no pus or drainage, this may be less likely, but it cannot be ruled out without further examination.

- Hemorrhoids: Given your history of internal hemorrhoids, it’s possible that they are contributing to your symptoms. Hemorrhoids can become thrombosed (clotted), leading to significant pain and discomfort.


Recommendations
1. Consult a Specialist: It is crucial to see a colorectal specialist or a gastroenterologist for a thorough examination. They may perform a digital rectal exam or an anoscopy to visualize the area and determine the exact cause of your symptoms.

2. Pain Management: In the meantime, continue with warm sitz baths, which can help soothe the area. Over-the-counter pain relief medications, such as ibuprofen or acetaminophen, may also help alleviate discomfort.

3. Dietary Adjustments: Ensure you are consuming a high-fiber diet to prevent constipation and straining during bowel movements. Staying hydrated is equally important.

4. Avoid Straining: If you feel the urge to go, try not to delay it, as this can lead to harder stools and increased pain.

5. Follow-Up: If symptoms persist or worsen, follow up with your healthcare provider promptly. They may recommend further imaging or even surgical options if a fistula or other complications are diagnosed.


Conclusion
Your symptoms warrant a careful evaluation to rule out serious conditions such as an anal fistula or complications from hemorrhoids. While it is understandable to feel anxious about these symptoms, timely consultation with a healthcare provider can lead to effective management and relief. Remember, early intervention is key to preventing further complications.
