Post-fistula surgery


It has been about a month since the drainage tube surgery (September 19).
I had a follow-up appointment last week (October 17), and the doctor checked the wound and found no major issues.
I was prescribed antibiotics and ointment to continue using.
Today, while showering, I noticed a small red circular bump near the wound.
Could this be a possible phenomenon during the recovery process? What could it be?

Without a personal examination, it is impossible to determine whether it is a recurrence or a scar.
If there is no redness, swelling, or pain, it is advisable to observe the situation first; otherwise, a follow-up examination and treatment by a physician are necessary.

After undergoing fistula surgery, it is essential to monitor the healing process closely, as various signs can indicate how well the body is recovering. Given that your surgery took place on September 19 and you had a follow-up appointment on October 17, it is reassuring that your doctor found no significant issues with the wound at that time. However, the appearance of a red, small, round protrusion near the surgical site can raise some concerns.

Firstly, it is important to understand that the healing process after fistula surgery can vary significantly from person to person. The body goes through several stages of healing, which can include inflammation, tissue formation, and remodeling. During the initial healing phase, it is common to experience some redness and swelling around the surgical site. This is part of the body's natural response to injury, as it sends more blood and immune cells to the area to facilitate healing.

The red protrusion you mentioned could be a few different things. One possibility is that it is a normal part of the healing process, such as granulation tissue. Granulation tissue is a new connective tissue that forms on the surface of a wound during the healing process. It is typically red or pink and may appear slightly raised. This tissue is essential for wound healing as it provides a foundation for new skin cells to grow over.

However, it is also important to consider other possibilities. If the protrusion is painful, increasing in size, or accompanied by other symptoms such as increased redness, warmth, or discharge, it could indicate an infection or another complication. Infections can occur post-surgery, and they may present with localized swelling, redness, and sometimes pus or other discharge. If you notice any of these symptoms, it is crucial to contact your healthcare provider promptly.

Another possibility is that the protrusion could be a suture or stitch that has not fully dissolved or has become exposed. In some cases, sutures can irritate the surrounding tissue, leading to localized inflammation and the formation of small lumps. If this is the case, your doctor may need to evaluate the area to determine if any intervention is necessary.

In terms of care, continue to follow your doctor's instructions regarding wound care, including the use of antibiotics and topical ointments. Keeping the area clean and dry is vital to prevent infection. If you have any concerns about the healing process or if the protrusion changes in appearance or becomes symptomatic, do not hesitate to reach out to your healthcare provider for further evaluation.

In summary, while the red protrusion you are experiencing could be a normal part of the healing process, it is essential to monitor it closely. If it shows signs of infection or does not improve, consult your doctor for further assessment. Healing after surgery can be complex, and open communication with your healthcare team is key to ensuring a smooth recovery.
