Post-Surgery Concerns: What to Do If Your Fistula Wound Opens? - Surgery

Post-anal fistula surgery


Dear Doctor,
I had a fistula surgery last week, and on the seventh day post-operation, the suture at the wound site came undone and is now hanging beside the wound.
My father mentioned that the wound is wide open, creating a hole.
Is this a concern? I have a follow-up appointment in two days (10 days post-surgery).
Should I urgently go to the emergency room for wound care? Currently, the wound is still oozing serous fluid, but there is no pus or any other abnormal signs; it’s just that the wound is open.

Dr. Ke Fangxu reply Surgery


It is normal for the sutures to hang and for the wound to open slightly one week post-operation, as this method is designed to stop bleeding without the need for suture removal.
Based on your description, the wound appears to be normal, and you can return for your follow-up appointment as scheduled.

More Info


After undergoing a fistula surgery, it is understandable to have concerns about the healing process, especially when you notice that the wound has opened up. Here’s a comprehensive response to your situation, addressing your concerns and providing additional insights into post-surgical care.

Firstly, it is not uncommon for surgical wounds, particularly those related to fistula surgeries, to experience complications such as opening or dehiscence (the separation of the wound edges). This can occur for various reasons, including tension on the wound, infection, or inadequate healing. The fact that you are noticing a significant opening in the wound, with the sutures having come undone, is understandably alarming.

1. Immediate Concerns: Since you mentioned that the wound is open and you are experiencing some drainage (serous fluid), it is essential to monitor the situation closely. The absence of pus or foul odor is a positive sign, as these could indicate an infection. However, the presence of fluid and the open nature of the wound should not be taken lightly. It is advisable to keep the area clean and covered with a sterile dressing to prevent contamination.

2. When to Seek Immediate Care: While you have a follow-up appointment in two days, if you notice any of the following symptoms before your appointment, you should seek immediate medical attention:
- Increased redness or swelling around the wound
- A significant increase in drainage or the presence of pus
- Fever or chills, which could indicate an infection
- Severe pain that is not relieved by over-the-counter pain medications
3. Follow-Up Appointment: During your follow-up visit, your surgeon will assess the wound and determine the best course of action. They may decide to re-suture the wound if it is deemed necessary or may recommend alternative treatments such as wound care management. It is crucial to communicate all your concerns during this visit, including any changes you have observed since the surgery.

4. Wound Care: In the meantime, here are some general wound care tips:
- Keep the wound clean: Gently clean the area with mild soap and water, avoiding any harsh scrubbing.

- Dress the wound: Use sterile gauze or a dressing to cover the wound, changing it regularly to keep the area dry and clean.

- Avoid activities that may strain the area: Limit physical activity that could put pressure on the wound, as this may hinder healing.

5. Healing Expectations: Healing from fistula surgery can take time, and it is not unusual for the recovery process to have ups and downs. The body’s healing response varies from person to person, and factors such as nutrition, overall health, and adherence to post-operative care can influence recovery.

6. Long-Term Considerations: If the wound does not heal properly, there may be a risk of complications such as recurrent fistulas or chronic wounds. Your healthcare provider will discuss any potential long-term implications based on the healing progress observed during your follow-up visits.

In conclusion, while it is concerning that your surgical wound has opened, it is essential to remain calm and take appropriate measures to care for the wound until your follow-up appointment. Keep monitoring for any signs of infection and maintain communication with your healthcare provider. They will guide you through the healing process and address any complications that may arise. Remember, your health and recovery are the top priorities, and seeking timely medical advice is crucial.

It is recommended to continue warm sitz baths and apply ointment. If there is any discharge, you can gently express it to keep the area clean. If the swelling is gradually improving, there is no need to worry. Typically, there is no immediate recurrence after the procedure.
