Surgical wound reopening : this issue must be considered in the context of discharge instructions and each individual's situation. Discovering that the edges of a surgical wound are separating can be very worrying. This opening, sometimes called dehiscence or wound separation, may only affect the skin or extend to deeper tissues. Its severity cannot be determined by its apparent width or from a photograph.
A wound that reopens must be reported to the team familiar with the procedure. The goal at home is not to close the wound, but to avoid manipulation, to provide accurate information, and to avoid delaying an assessment. Discharge instructions always take precedence over this guide.
What does it mean when a surgical wound reopens?
The visible opening does not reveal its depth
Not all layers of a surgical closure are visible. A small skin tear may remain superficial, while a deeper opening may involve the tissues beneath the skin. The area operated on, the type of closure, the presence of an implant or drain, and the patient's overall health all influence the assessment.
A photo can help, but not determine the outcome.
An image can document spacing, color, or flow if requested by the service through a designated channel. It does not show depth, the solidity of deep planes, heat, odor, sensitivity, or circulation. Therefore, it should not be used as a reason to await further advice.
Why is it necessary to contact the team even if the opening seems small?
The opening may be due to tension in the area, bleeding, a fluid collection, infection, or fragile wound healing, without the underlying cause being identifiable. The surgical team is familiar with the procedure, the tissues involved, and the expected appearance. They can decide whether observation, consultation, or urgent evaluation is necessary.
Don't wait until the wound becomes painful or a fever develops. Even an opening without fever may still warrant examination. The guide on surgical wound infection reminds us that local signs and the patient's overall condition must be considered together.
What should you do when you notice the opening?
Stop the manipulations and limit friction.
Do not pull on the edges to check their strength, and do not pull the wound apart to look inside. Avoid contact with clothing and keep your hands away. If a dressing is already in place, do not remove it to perform additional checks. Report to the department if it has shifted, become soiled, or is saturated.
Ask how to protect the area during orientation
Protection depends on the depth of the wound, the bleeding, the location, and the device already in place. Use only the equipment and techniques specified in your documents or by a professional. If no instructions apply to the situation, call before adding any product or improvising a dressing. In an emergency, follow the dispatcher's instructions.
Our article on post-operative dressings explains why a device cannot be chosen solely based on surface appearance.
What actions should absolutely be avoided?
- Do not bring the edges together with glue, strips, ribbon or improvised stitches.
- Never push any visible tissue back inside the wound.
- Do not remove a thread, staple, surgical glue or drain.
- Do not pour antiseptic, alcohol, powder or homemade preparation into the opening.
- Do not massage, squeeze, or attempt to drain any liquid.
- Do not modify a prescribed treatment on your own, especially if it affects coagulation.
Closing the surface without knowing the condition of the underlying tissues can trap fluid, mask a complication, or complicate the examination. The decision to leave it open, change the dressing, or close it rests with the team after evaluation.
What information should I prepare for the call?
- The name of the procedure and the area operated on.
- The moment when the gap was observed and its evolution.
- The presence of new bleeding, fluid, odor, or pain.
- The condition of the dressing, drain, threads, staples or glue.
- General symptoms: malaise, chills, difficulty breathing or unusual alertness.
- Ongoing treatments and specific instructions given upon discharge.
Describe the facts without attempting to name the complication. A photograph can be included in the call if requested. The home return checklist helps keep the service number and necessary documents readily available.
When should you call 15 or 112 immediately?
Call 15 or 112 if the opening exposes deep tissues or an organ, if the bleeding is significant, if the wound suddenly opens with intense pain, or if the patient's general condition deteriorates rapidly. Severe discomfort, loss of consciousness, confusion, significant difficulty breathing, or chest pain also require immediate medical attention.
State from the outset that a recent operation has taken place and that the wound has reopened. Do not drive yourself if you are weak, unwell, short of breath, or experiencing significant bleeding. Follow the instructions given over the phone.
What signs suggest an associated problem?
Bleeding or collection of blood under the wound
Increased swelling, becoming tense or asymmetrical, blood seeping through the dressing, increasing pain, or changes in sensation should be reported. These are not sufficient to diagnose a hematoma. The guidelines in the article on postoperative hematomas can help prepare a useful description without manipulating the area.
Infection or tissue damage
Localized heat, increasing redness, cloudy or foul-smelling fluid, a marked change in skin color, new pain, or a decline in recovery warrants prompt medical attention. A normal temperature does not rule out a complication; conversely, a fever after surgery alone does not reveal the cause.
Do certain situations require greater vigilance?
The presence of an implant, drain, stoma, or deep abdominal incision alters the situation. The same is true for an immunocompromised individual, someone with a chronic illness, nutritional deficiencies, a clotting disorder, or a recent infection. These factors do not allow us to predict the outcome, but they must be communicated to the medical team.
An itch or a visible stitch should not lead to scratching the area. Consult the guide on itchy scars after surgery to distinguish between sensations to describe and actions that might trigger the closure.
What can the team decide after the review?
The professional can examine the depth, look for bleeding or infection, check the tissues, hardware, and circulation, and then choose the appropriate protection or treatment. A wound may sometimes heal without further closure; another may require specialized care or intervention. This decision cannot be standardized based on a single image.
F.A.Q
Can we add another strip to bring the edges together?
Not without explicit instructions from a professional familiar with the wound. A home closure can mask its depth, retain fluid, or delay assessment.
Is the absence of pain reassuring?
It's not enough. Sensitivity varies depending on the procedure and the nerves involved. A painless opening should still be reported.
Should we wait for the next scheduled appointment?
Not without advice. Contact the team as soon as you find out about the opening so they can decide on the right level and location for the assessment.
