Post-Surgery Concerns: Managing Discharge and Bleeding After Fistula Repair - Surgery

Anal fistula


Hello doctor, I had a fistula surgery a month ago.
The outside of the wound looks like it has healed, but there is still a little discharge that resembles pus.
Is this normal? Also, last week I experienced some bleeding while using the restroom due to hard stools.
Will this affect the healing of the wound? I already had hemorrhoids, but they weren't severe, and I didn't have them addressed during the surgery.

The recovery period after fistula surgery is generally longer, typically requiring one to two months.
During this time, there may be discharge from the wound.
If the wound has healed but purulent discharge appears, it may indicate a recurrence of the fistula.
It is generally recommended to first use antibiotic treatment and then consider whether a repeat surgery is necessary based on the recovery status.

More Info


After undergoing a fistula repair surgery, it is not uncommon to experience some discharge from the surgical site, especially in the initial weeks following the procedure. The presence of a small amount of discharge, which may appear yellowish or like pus, can be a normal part of the healing process. However, if the discharge is excessive, has a foul odor, or is accompanied by increased pain or swelling, it could indicate an infection, and you should consult your healthcare provider promptly.

Regarding the bleeding you experienced due to hard stools, this can indeed have an impact on the healing of your surgical site. Straining during bowel movements can put pressure on the area, potentially leading to bleeding and disrupting the healing process. Since you mentioned having a history of hemorrhoids, this could further complicate matters, as the increased pressure can exacerbate both the hemorrhoids and the surgical site.

To promote healing and minimize complications, consider the following recommendations:
1. Dietary Adjustments: Focus on a high-fiber diet to soften your stools. Foods rich in fiber include fruits, vegetables, whole grains, and legumes. Additionally, staying well-hydrated by drinking plenty of water can help prevent constipation.

2. Stool Softeners: If dietary changes are not sufficient, you may want to discuss the use of over-the-counter stool softeners with your doctor. These can help make bowel movements easier and reduce the risk of straining.

3. Gentle Hygiene Practices: After bowel movements, gently clean the area with warm water. Avoid using harsh soaps or wipes that may irritate the skin. You can also consider sitz baths to soothe the area and promote healing.

4. Monitor Symptoms: Keep an eye on the discharge and any bleeding. If you notice an increase in the amount of discharge, a change in its color or odor, or if the bleeding persists or worsens, it is crucial to seek medical attention. Your healthcare provider may want to assess the surgical site to ensure there are no complications.

5. Follow-Up Appointments: Attend all scheduled follow-up appointments with your surgeon or healthcare provider. They can monitor your healing progress and address any concerns you may have.

6. Avoid Straining: If you feel the urge to have a bowel movement, do not delay it, as this can lead to harder stools. If you are having difficulty, consider using a footstool to elevate your feet while sitting on the toilet, which can help facilitate easier bowel movements.

In summary, while some discharge and minor bleeding can be normal after fistula repair surgery, it is essential to manage your bowel health proactively to avoid complications. By making dietary changes, practicing good hygiene, and monitoring your symptoms, you can support your recovery and minimize the risk of further issues. If you have any concerns or if your symptoms worsen, do not hesitate to reach out to your healthcare provider for guidance.
