CiNPWT Using in Mastectomy Wound Care After DIEP Flaps for Breast Reconstruction

Background: Closed-incision negative pressure wound therapy (ciNPWT) is effective in reducing postoperative complications, yet its use in free flap breast reconstruction mastectomy wound remains controversial due to concerns that external pressure may compromise the microvascular pedicle. Methods: A retrospective comparative study was conducted on 253 patients (283 flaps) undergoing immediate DIEP flap reconstruction between 2012 and 2025. Patients were stratified into a ciNPWT group and a conventional dressing group. Outcomes included flap survival, wound complications, healing time, and length of stay (LOS). Multivariable regression models adjusted for confounders, including BMI and neoadjuvant chemotherapy.
