Acute wound failure encompasses several postoperative complications that all result from partial or total disruption of the surgical wound.

Wound Failures

  • Fascial dehiscence: breakdown of fascia
  • Evisceration: extrusion of bowel from the abdominal cavity
  • Acute hemorrhage: blood loss
  • Incisional hernia: hernia located through site of prior surgical incision
  • Anastomotic leaks: failure of bowel healing
  • Fistulas: abnormal connection

Risk Factors

  • Age
  • Diabetes
  • Malnutrition
  • Uremia
  • Immunosuppression
  • Jaundice
  • Sepsis
  • Hypoalbuminemia
  • Cancer
  • Obesity
  • Steroid use
  • Inadequate closure: suture too close to fascia edge, too far from fascia edge, too far apart, too much tension
  • Increased intra-abdominal pressure
  • Infection
  • Radiation 

Presentation

  • Drainage of serosanguinous fluid from wound
  • Evisceration without warning → often have ripping sensation with intense coughing/emesis

Treatment

  • Treatment depends on timing
  • Early and without evisceration → reclosure of fascia
  • Late → local wound care and abdominal binders
  • Complete wound dehiscence with evisceration → immediate reoperation 
  • Dehiscence due to infection → debridement of fascial edges and close without tension
  • Abdomen can also be left open in certain situations, such as when there is an ongoing infection or bowel injury

Relevant Information

  • Most common to occur during inflammatory phase (post-op days 1-7)
    • During this period of time, the strength of the wound is dependent upon the suture and knot strength
    • Strength of wound increases over time during fibrotic phase and becomes less reliant on closure methods
  • May be an early manifestation of an intra-abdominal process, such as an abscess of anastomotic leak
