Granulation tissue at the wound site after fistula surgery?


Hello Doctor, I underwent a fistula surgery at the end of March.
The doctor made the incision deeper and larger (approximately 3 to 5 centimeters in diameter) to prevent recurrence.
The healing process has been relatively good, with only about 1 centimeter left that hasn't fully healed.
The doctor initially prescribed me iodine ointment, which was later changed to antibiotic ointment before I traveled abroad on April 16.
I monitor the healing of the wound daily, and this week I noticed a small white spot (about the size of half a grain of rice) inside the still pink, not fully healed area of the wound.
Could this possibly indicate a recurrence? When I first discovered it, pressing on that area with a cotton swab caused some bleeding, but it has since decreased.
Currently, there is still a little bit of discharge from the wound.
Since I am now abroad, I am unsure of what to do.
I would appreciate your guidance.

If you are abroad for a short period and will not be returning, as long as there is no swelling, pain, or discharge, it should not be a concern.
However, to determine if there is a recurrence, a medical examination is necessary.
If you experience any fever, you should seek medical attention as soon as possible.

More Info


After undergoing fistula surgery, it is common to have concerns about the healing process, particularly when it comes to the appearance of granulation tissue and any unusual findings at the surgical site. Granulation tissue is a normal part of the healing process and consists of new connective tissue and tiny blood vessels that form on the surface of a wound during the healing phase.
In your case, it sounds like you are experiencing a typical healing response, especially given that your wound is still in the process of healing. The small white bump you described, which is about the size of a grain of rice, could very well be granulation tissue. This tissue can appear as a raised, pinkish area that may have a whitish or yellowish hue due to the presence of new cells and blood vessels. It is not uncommon for granulation tissue to bleed slightly when pressure is applied, especially if it is still in the process of maturing and integrating with the surrounding tissue.

The fact that you have a small amount of discharge is also not unusual. As the wound heals, some drainage can occur, particularly if the area is still inflamed or if there is a small amount of fluid accumulation. However, it is essential to monitor the characteristics of this discharge. If it becomes foul-smelling, changes color significantly, or increases in volume, these could be signs of infection, and you should seek medical attention as soon as possible.

Regarding your concern about the possibility of recurrence, it is important to note that while the formation of granulation tissue is a normal part of healing, any persistent or unusual growths should be evaluated by a healthcare professional. If you are currently abroad and unable to see your surgeon, consider reaching out to a local healthcare provider who can assess the wound and provide guidance. They may be able to perform a physical examination and determine whether the tissue is indeed granulation tissue or if further intervention is necessary.

In the meantime, continue to follow your surgeon's post-operative care instructions, including the application of any prescribed ointments and maintaining cleanliness at the surgical site. Avoid any activities that could put strain on the area, and ensure you are eating a balanced diet to support healing.

If you experience increased pain, significant swelling, or any other concerning symptoms, it is crucial to seek medical attention promptly. Healing from fistula surgery can take time, and while it is natural to feel anxious about the process, staying informed and proactive about your care can help alleviate some of your concerns. Remember that every individual's healing process is unique, and patience is key as your body works to recover.
