Perianal fistula (anal fistula) surgery is one of the most specialized areas of proctology. The success of the surgery depends not only on the operation performed or the devices used but also on the patient’s post-operative care.
My patients often ask, “Doctor, the surgery is over, am I finally free of this?” My answer is always: “We have passed the halfway point; now we will manage the remaining half (the recovery process) together.”
So, how does the recovery process progress after fistula surgery? When does the open wound close, and what should you pay attention to in order to prevent recurrence? As a General Surgery Specialist, I would like to explain this sensitive process step by step.
The First Days After Surgery: What to Expect?
In the first few days after perianal fistula surgery, mild pain and leakage are completely normal. Especially in patients who have undergone “Fistulotomy” (opening the tunnel) or “Seton” (application of a surgical string), the wound must remain open for a while because healing occurs “from the bottom to the surface.”
- Bleeding: In the early days, there may be bleeding and discharge in the form of leakage, enough to soil a pad. Do not worry.
- Pain: It is a manageable pain that can be controlled with painkillers. we do not expect an unbearable throbbing.
How Long is the Recovery Period?
The answer to the frequently asked question, “How many hours does perianal fistula surgery take?” is usually a short period of 30-40 minutes. However, the recovery process can take weeks, independent of the duration of the surgery, depending on the depth of the wound and the technique applied.
- Simple Fistula: The wound usually closes completely within 4-6 weeks.
- Complex Fistula (Seton/LIFT): The process can extend up to 2-3 months.
Patience is our greatest medicine here. It is not the early closure of the wound that matters, but the correct closure (filling from the inside out). If the top of the wound (the skin part) closes prematurely, a space remains inside, which is a cause for “recurrence” (reappearance).
Golden Rules to Prevent Recurrence: Sitz Baths
The biggest cause of recurrence after a successful fistula surgery is inadequate wound care. The most important thing you should do in the post-operative period is the Warm Water Sitz Bath.
- Purpose: Warm water reduces pain by relaxing the muscles in that area and prevents the accumulation of inflammation by cleaning the inside of the wound.
- Application: You should sit in a basin filled with warm water 3-4 times a day for 10-15 minutes. There is no need to add Betadine or medication unless your doctor recommends it; plain water is sufficient.
- Cleaning: After using the toilet, you should wash the area gently with a showerhead (not with pressurized water) and definitely dry it after the sitz bath. Moisture can lead to fungus and itching.
When Should You Consult a Doctor?
There may be some fluctuations during the healing process. However, if the following symptoms occur, you should contact your physician without waiting:
- Fever rising above 38°C (Could be a sign of infection).
- Worsening of the color and odor of the discharge.
- Suddenly increasing swelling and unbearable pain in the surgery area.
Conclusion: Patience and Follow-up
Fistula treatment is not a sprint; it is a marathon. Your surgeon removes the tunnel, but the healthy filling of that tissue is your body’s biological process.
During this process, not neglecting your regular check-ups, performing wound care meticulously, and staying in communication with your surgeon is the safest path to permanent healing.
