Could a vacuum dressing slash infection rates after major abdominal surgery?
NCT ID NCT05977816
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This trial tests whether a negative pressure wound therapy (NPWT) dressing — a special vacuum-sealed bandage — can reduce surgical site infections and improve scar appearance compared to a standard dressing in people who have had a midline laparotomy (a large abdominal incision). About 2,000 adults undergoing this type of surgery will be randomly assigned to receive either the NPWT dressing or a standard dressing after their operation. Researchers will track infection rates for up to six months and also measure quality of life and scar healing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Negative Pressure Wound Therapy (NPWT) dressing applied to the wound after surgery
- What this could lead to
- If it works, this could establish NPWT as a better way to prevent surgical site infections and improve scar healing after abdominal surgery.
- What could go wrong
- This is a single trial, and results may not apply to all types of abdominal surgery. NPWT dressings can be more expensive and may cause skin irritation in some patients.
