Understanding Dehiscence: Causes, Symptoms, and Management


Dehiscence, a term primarily used in medicine and botany, refers to the splitting or bursting open of a structure. In surgical contexts, dehiscence can describe the rupture of a wound along surgical suture lines. In botany, it refers to the opening of fruits or seeds to release contents. This article focuses on surgical wound dehiscence, a critical issue in postoperative care, exploring its causes, symptoms, and effective management strategies.

What is Surgical Wound Dehiscence?

Surgical wound dehiscence occurs when a wound that was previously closed by sutures, staples, or other methods reopens either partially or completely after surgery. This complication can delay healing, increase the risk of infection, and extend hospital stays. It is most commonly associated with abdominal surgeries but can occur following any surgical procedure.

Causes of Wound Dehiscence

Several factors can contribute to the risk of wound dehiscence:

  1. Poor Wound Healing: Factors like malnutrition, age, diabetes, and smoking can impair the body’s ability to heal effectively.
  2. Surgical Site Infection: Infections can weaken the tissue around the surgical site, leading to dehiscence.
  3. Mechanical Stress: Physical strain on the wound, such as coughing, vomiting, or inadequate support, can cause the sutures to strain and the wound to reopen.
  4. Technical Errors in Surgery: Incorrect suture technique or the choice of suture material may lead to inadequate wound closure.

Symptoms of Wound Dehiscence

Recognizing the symptoms of wound dehiscence early is crucial for timely intervention. Symptoms may include:

  • Visible gaps in the sutures or staples
  • Redness or swelling around the wound
  • Pain or discomfort around the site
  • Fluid discharge, which may be clear, pus-filled, or bloody
  • A feeling of ‘giving way’ or bursting sensation at the wound site

Management and Treatment

Immediate Steps

If wound dehiscence occurs, it is crucial to contact a healthcare provider immediately. Initial management may include:

  • Protecting the wound from further damage
  • Covering the wound with sterile dressings to prevent infection
  • Resting and avoiding any activity that puts stress on the wound

Medical Interventions

Treatment options depend on the severity of dehiscence:

  • Minor Dehiscence: Minor cases may be managed with conservative treatments like wound dressings and monitoring.
  • Major Dehiscence: This might require surgical intervention to re-suture the wound under more controlled conditions. In some cases, negative pressure wound therapy (NPWT) may be used to promote healing by aiding in fluid drainage and increasing blood flow to the area.

Preventive Measures

Preventing wound dehiscence begins with thorough preoperative, intraoperative, and postoperative care:

  • Preoperative: Ensuring good nutritional status, managing diabetes, and cessation of smoking can enhance wound healing capabilities.
  • Intraoperative: Using appropriate suture materials and techniques and ensuring aseptic conditions can minimize infection risks.
  • Postoperative: Educating patients on how to care for their wounds and recognizing early signs of complications plays a critical role in prevention.


Surgical wound dehiscence is a serious complication that can have significant implications for patient health and recovery. By understanding the causes and symptoms, healthcare providers can implement effective management strategies to minimize the risk of this condition. Prevention, through comprehensive care and patient education, remains the cornerstone of managing surgical wound dehiscence.
