Brief Summary in Lay Language

More than 20% of patients develop surgical site infections following colorectal surgery, which cause substantial morbidity, prolongation of hospital stay, costs and even mortality. A novel negative pressure incision therapy device, which is applied for 5-7 days postoperative, was developed to reduce surgical site infections by continuous removal of wound secretion from the incisional wound. However, the device has not yet been tested in a high-quality trial and its effectiveness is therefore unclear. The Poniy trial will investigate, whether this negative pressure incision therapy device reduces wound infections in comparison to standard wound coverage in patients undergoing open elective colorectal surgery.

Brief Summary in Scientific Language

The aim of the trial is to investigate whether negative pressure incisional therapy for 5-7 days postoperative significantly reduces postoperative surgical site infections in comparison to standard wound dressings following open elective abdominal surgery.
