Massive bleeding from anal fistula?


I have been diagnosed with a fistula for nearly a month, and due to work commitments, I am unable to schedule surgery at this time.
Currently, the fistula has developed an opening, and I am using antibiotic ointment and maintaining cleanliness.
Occasionally, I experience some mild pain and pus, which I promptly express in the restroom.
Recently, after feeling pus accumulation, I went to the restroom to express it, and initially, there was a small amount of pus, followed by a significant amount of bleeding.
I searched online but found no relevant information.
What could be the cause of the significant bleeding from the fistula?

If an anal fistula is not surgically treated, it can lead to recurrent inflammation, resulting in the accumulation of pus and blood within the fistula.
Therefore, squeezing it may cause bleeding.
Since the fistula is very close to the hemorrhoidal tissue and may even pass through it, significant bleeding after squeezing is not unusual.
It is advisable to consult a physician for diagnosis and treatment if you experience discomfort.
If surgery is not immediately feasible, oral medications can be prescribed to manage symptoms.
Self-squeezing is not recommended, as it may lead to excessive bleeding or severe infection.

More Info


Heavy bleeding associated with an anal fistula can be concerning and may arise from several underlying causes. An anal fistula is an abnormal connection between the anal canal and the skin surrounding the anus, often resulting from an infection or abscess in the anal glands. When a fistula is present, it can lead to recurrent infections, inflammation, and sometimes significant bleeding.


Causes of Heavy Bleeding from an Anal Fistula
1. Infection and Abscess Formation: The most common cause of bleeding in the context of an anal fistula is infection. If the fistula becomes infected, it can lead to the formation of an abscess, which may rupture and cause bleeding. The pus and blood may be expelled when you apply pressure during bowel movements or when the area is squeezed.

2. Inflammation: Chronic inflammation around the fistula can lead to the erosion of blood vessels in the surrounding tissue. This erosion can result in bleeding, especially if the tissue becomes fragile due to ongoing irritation or infection.

3. Trauma: If the fistula is manipulated or if there is excessive straining during bowel movements, it can lead to trauma in the area, resulting in bleeding. This is particularly relevant if there is a significant amount of pus that needs to be expelled, as the pressure can cause small blood vessels to rupture.

4. Fistula Characteristics: The type of fistula can also influence the bleeding. For example, a complex fistula that involves multiple tracts or is associated with other conditions (like Crohn's disease) may have a higher risk of complications, including bleeding.

5. Underlying Conditions: Certain underlying health conditions, such as inflammatory bowel disease (IBD), can exacerbate the symptoms associated with an anal fistula, including bleeding. If you have a history of such conditions, it is essential to consider them in the context of your symptoms.


Management and Recommendations
Given your situation, where you have been diagnosed with an anal fistula and are experiencing significant bleeding, it is crucial to take the following steps:
1. Seek Medical Attention: While you mentioned that surgery is not currently an option due to work commitments, it is essential to consult with a healthcare provider as soon as possible. They can assess the severity of the bleeding and the condition of the fistula.
2. Maintain Hygiene: Continue to keep the area clean to prevent further infection. Warm sitz baths can help soothe the area and promote healing.

3. Monitor Symptoms: Keep track of the amount and frequency of bleeding, as well as any accompanying symptoms such as pain, fever, or changes in bowel habits. This information will be valuable for your healthcare provider.

4. Consider Pain Management: If you are experiencing pain or discomfort, discuss pain management options with your doctor. Over-the-counter pain relievers may help alleviate some discomfort.

5. Antibiotics: If you notice signs of infection (increased redness, swelling, or pus), it may be necessary to start or adjust antibiotic therapy. Ensure that any topical treatments you are using are appropriate for your condition.

6. Plan for Surgery: Once your work situation allows, consider scheduling surgery to address the fistula. Surgical intervention is often the most effective way to resolve the issue and prevent future complications.


Conclusion
Heavy bleeding from an anal fistula can be a sign of infection, inflammation, or trauma. It is essential to address these symptoms promptly with a healthcare professional to prevent further complications. While managing the condition conservatively is possible, surgical intervention is often necessary for long-term resolution. Always prioritize your health and seek medical advice when experiencing significant symptoms.
