Negative Pressure Wound Therapy for Complex Surgical Wounds in 59 Patients Across Secondary and Tertiary Care Centers...

Complex wounds are associated with a challenging healing process, prolonged hospitalization, increased treatment cost, and workforce loss. In this case series, negative pressure wound therapy (NPWT) with and without instillation and dwell time (NPWTi-d), closed incision negative pressure therapy (ciNPT), and open abdomen negative pressure therapy (OA-NPT) use in the management of complex wounds were examined.

Fifty-nine patients (mean age, 55.0 ± 14.8 years) across secondary and tertiary care centers in Turkey were treated. Patients were examined, and a NPWT system was selected based on wound care needs. Dressing changes occurred every 2 to 7 days, depending on therapy type. Wound closure occurred through surgical closure or secondary intention.

Patient wound types consisted of acute wounds (n = 10), chronic wounds (n = 34), postoperative wound dehiscence (n = 9), and tumor resection/flap necrosis (n = 6). Thirty-six patients (61.0%) received NPWT, 16 (27.1%) received NPWTi-d, 5 (8.5%) received ciNPT, and 2 (3.4%) received OA-NPT. Average treatment duration was 19.7 ± 13.7 days. Surgical closure occurred in 45 patients, and secondary closure was observed in 13 patients; the remaining patient showed wound improvement. Wound healing complications were observed in 2 patients (scar formation and partial flap necrosis).

Our findings indicate an association of negative pressure therapy with favorable wound healing outcome in complex wounds. Negative pressure therapy seems to be a useful treatment option to bridge wound care between initial debridement and final reconstruction.
