Wound Dehiscence

Wound dehiscence is partial or complete separation of previously approximated surgical wound edges. The separation may involve only the skin or extend through subcutaneous tissue, fascia, muscle, tendon, or an underlying organ or implant. The visible gap does not determine the full depth of the defect. A small skin opening can overlie a deeper fascial failure. Fascial dehiscence is particularly dangerous because the abdominal wall or another surgical closure may no longer contain the underlying viscera. Evisceration occurs when organs or other internal contents protrude through the disrupted wound. Dehiscence commonly becomes apparent during the early postoperative healing period, often approximately 3–10 days after surgery. The timing varies with the procedure, incision location, infection, tissue perfusion, and the patient’s healing capacity. New or increasing serosanguineous drainage, a sudden sensation that the wound “gave way,” widening separation, or a new bulge deserves assessment rather than reassurance that the drainage is routine.
