(Surgical Wound Dehiscence; Operative Wound Dehiscence)
Pronounced: dē-his’ ens
Wound dehiscence is the parting of the layers of a surgical wound. Either the surface layers separate or the whole wound splits open. This is a serious condition and requires care from your doctor.
Wound dehiscence varies depending on the kind of surgery you have. The following is a list of generalized causes:
- Infection at the wound
- Pressure on sutures
- Sutures too tight
- Injury to the wound area
- Weak tissue or muscle at the wound area
- Incorrect suture technique used to close operative area
- Poor closure technique at the time of surgery
- Use of high-dose or long-term corticosteroids
- Severe vitamin C deficiency (scurvy)
The following factors increase your chance of developing wound dehiscence.
- Increasing age
- Poor nutrition
- Malignant growth
- Presence of prior scar or radiation at the incision site
- Non-compliance with post-operative instructions (such as early excessive exercise or lifting heavy objects)
- Surgical error
- Increased pressure within the abdomen due to: fluid accumulation (ascites); inflamed bowel; severe coughing, straining, or vomiting
- Long-term use of corticosteroid medications
Other medical conditions, such as
diabetes, kidney disease, cancer,immune problems, chemotherapy, radiation therapy
If you experience one or more of these symptoms in the surgical area, contact your doctor.
- Broken sutures
- Open wound
Your doctor will ask about your symptoms and examine the surgical area. Tests may include the following:
- Antibiotic therapy
- When appropriate, frequent changes in wound dressing to prevent infection
- When appropriate, wound exposure to air to accelerate healing and prevent infection, and allow growth of new tissue from below
- Surgical removal of contaminated, dead tissue
- Placement of a temporary or permanent piece of mesh to bridge the gap in the wound
If you are diagnosed with wound dehiscence, follow your doctor's instructions .
