Postoperative wound issues following anal fistula surgery?


Hello Doctor, I had a follow-up appointment last week, and the doctor said that my wound is healing well and advised me to monitor it for another two weeks.
If there are any issues, I should return for another visit.
However, I have recently noticed that my surgical wound is still slightly red, swollen, and painful.
Additionally, I have two types of discharge: sometimes it resembles the yellow-green discharge from the last picture, but it has become thicker and the amount is slightly less.
Other times, the discharge is a light yellow, watery consistency, especially after having a bowel movement, when I notice more of this watery discharge.
Should I return for a follow-up appointment? Could this be a sign of recurrence, or is it part of the normal healing process? Currently, it is the fifth week post-surgery.

Thank you, Doctor, for clarifying this.

The wound shown in the photo is clean with no signs of recurrence.
The postoperative discharge is a normal phenomenon.
If there are no specific discomforts, a follow-up visit may not be necessary.

More Info


After undergoing anal fistula surgery, it is common to have concerns about the healing process, especially when experiencing symptoms such as redness, swelling, and discharge from the surgical site. Based on your description, it seems that you are currently in the fifth week post-surgery, and while the doctor has indicated that your wound is healing well, you are observing some concerning signs.

Firstly, it is important to understand that the healing process after anal fistula surgery can vary significantly among individuals. Generally, the surgical site may exhibit some redness and swelling as part of the normal healing process. However, persistent or increasing redness, swelling, and pain can indicate complications such as infection or improper healing. The presence of discharge is also a critical factor to consider.
The two types of discharge you mentioned—thick yellow-green discharge and thin, watery yellow discharge—can provide important clues about your healing status. Thick, purulent discharge (yellow-green) may suggest an infection, especially if it is accompanied by increased pain, fever, or worsening symptoms. On the other hand, thin, watery discharge can sometimes be a normal part of the healing process, particularly after bowel movements, as the area may still be sensitive and producing mucus.

Given that you are experiencing both types of discharge, it is advisable to err on the side of caution. If the discharge continues, especially if it becomes more pronounced or if you develop additional symptoms such as fever or increased pain, you should definitely return to your healthcare provider for further evaluation. It is crucial to rule out any potential complications, including infection or the possibility of a recurrence of the fistula.

In terms of wound care, maintaining proper hygiene is essential. Gently cleaning the area with mild soap and water, avoiding harsh chemicals, and keeping the area dry can help promote healing. Additionally, following any specific instructions provided by your surgeon regarding wound care and activity restrictions is vital.

You mentioned that your doctor advised you to observe the wound for two weeks. If you notice any significant changes or if your symptoms worsen before that time frame, do not hesitate to seek medical attention. It is better to have a healthcare professional assess the situation than to risk complications that could prolong your recovery.

In summary, while some redness and discharge can be normal post-surgery, the specific characteristics of your symptoms warrant a closer look. Monitoring your symptoms closely and maintaining open communication with your healthcare provider will be key in ensuring a smooth recovery. If in doubt, always prioritize your health and seek medical advice when you have concerns about your healing process.
