Background:
Implant infection is problematic in breast reconstruction. Traditionally, infected tissue expanders (TE)/implants are removed for several months before replacement, resulting in breast reconstruction delay. Salvage involving device removal, negative pressure wound therapy with instillation and dwell (NPWTi-d) placement, and early staged TE/implant replacement within a few days has been described. The purpose of this study was to compare outcomes of the NPWTi-d salvage pathway with traditional implant removal.
Methods:
A retrospective review was performed on patients who underwent implant-based reconstruction and developed TE/implant infection/exposure requiring removal. Patients were divided into two groups. Group 1 had TE/implant removal, NPWTi-d placement, and TE/implant replacement 1-4 days later. Group 2 (control) underwent standard TE/implant removal and no NPWTi-d. Reinfection after TE/implant salvage, TE/implant-free days, and time to final reconstruction were assessed.
Results:
The study included 47 patients (76 TE/implants) in group 1 (13 patients, 16 TE/implants) and group 2 (34 patients, 60 TE/implants). The success rate (no surgical-site infection within 90 days) of implant salvage was 81.3% in group 1. No group 1 patients abandoned completing reconstruction after TE/implant loss versus 38.2% (13 of 34) in group 2 (P = 0.0094). Mean implant-free days was 2.5 ± 1.2 in group 1 versus 134.6 ± 78.5 in group 2 (P = 0.0001). The interval to final implant-based reconstruction was 69.0 ± 69.7 days in group 1 versus 225.6 ± 93.6 days in group 2 (P = 0.0001).
Conclusions:
A breast implant salvage pathway with infected device removal, NPWTi-d placement, and early TE/implant replacement was successful in 81.3%. Patients experienced 132 less implant-free days and faster time to final reconstruction.
