Clinical Scorecard: Prophylactic Negative Pressure Wound Therapy for Closed Incisions in Patients Undergoing Major Complex Abdominal Wall Reconstruction

At a Glance

Key Highlights

• Patients undergoing major complex abdominal wall repair have high risk (29–66%) of surgical site occurrences including infections.
• pNPWT is a sealed system applying negative pressure on closed incisions to prevent wound complications.
• Study compared outcomes before and after implementation of pNPWT in a tertiary center, focusing on superficial and deep wound infections.

Guideline-Based Recommendations

Diagnosis

• Classify wound infections using CDC SSI criteria (superficial, deep, organ space).
• Use clinical signs (purulent drainage, pain, swelling, erythema) and culture results when available.
• Identify anastomotic leakage via contrast radiography or relaparotomy.
• Define seroma as subcutaneous fluid without infection; infected seroma scored as superficial SSI.

Management

• Apply pNPWT on closed incisional wounds postoperatively starting immediately after surgery.
• Continue NPWT beyond postoperative day 5 if wound dehiscence occurs; do not continue solely for edema without infection.
• Use systemic antibiotic prophylaxis and antiseptic rinsing as adjunct measures.
• Manage bleeding or hematoma with radiologic drainage if needed.
• Intervene with radiologic or surgical drainage for intra-abdominal or extra-abdominal collections.

Monitoring & Follow-up

• Monitor wounds daily for signs of infection, dehiscence, or fluid collections.
• Assess need for continued NPWT at dressing changes, especially postoperative day 5.
• Track emergency visits, readmissions, and 30-day mortality postoperatively.

Risks

• High risk of wound complications due to contamination, foreign body implantation, and patient factors (smoking, obesity, malnutrition).
• Potential for wound infections, seroma, hematoma, skin/fat necrosis, wound dehiscence, anastomotic leakage, intra-abdominal abscess, and enterocutaneous fistulas.

Patient & Prescribing Data

Adults undergoing elective open major complex abdominal wall reconstruction with primary skin closure

Implementation of pNPWT as standard care post-2014 aimed to reduce incidence of superficial and deep wound infections and other wound complications.

Clinical Best Practices

• Use pNPWT on closed incisions in high-risk complex abdominal wall reconstruction patients.
• Ensure primary skin closure at end of surgery before applying pNPWT.
• Combine pNPWT with systemic antibiotic prophylaxis and antiseptic measures.
• Carefully monitor wounds for infection signs and continue NPWT if dehiscence develops.
• Document and classify wound complications rigorously using CDC SSI criteria.
