Usefulness of Incisional Negative Pressure Wound Therapy for Decreasing Wound Complication Rates and Seroma Formation Following Prepectoral Breast Reconstruction

초록

Background Seroma is a common complication in prepectoral breast reconstruction. PICOTM dressing, a type of incisional negative pressure wound therapy (iNPWT), was used to reduce complications postoperatively. Methods This study was a retrospective cohort study that included patients who underwent prepectoral breast reconstruction between February 2017 and July 2019. There were two groups: one that received PICOTM dressing and a control group. The frequencies of overall complications, major seromas, and reoperations were analyzed. The durations and total amounts of seromas were also analyzed. Result Sixty patients were included in this study (PICOTM : 37 and non-PICOTM patients: 23). The overall incidence of complications, major seromas, and frequency of reoperations were lower in the PICO group compared to the non-PICOTM group (18.9% vs. 52.2%, p = 0.007; 16.2% vs. 43.5%, p = 0.020; 2.7% vs. 26.1%, p = 0.006, respectively). Univariate analysis was used to analyze the risk factors for complications due to the application of PICOTM dressing and showed statistically significant results for any complication. When univariate analysis was performed on risk factors for seroma, the duration of seroma showed statistical significance in association with PICOTM dressing status and mastectomy volume. The total number of patients who developed seroma was statistically correlated with age, PICOTM dressing status, and mastectomy volume. Conclusions PICOTM dressing after prepectoral breast reconstruction could be a useful tool for reducing the frequency of complications and major seroma, as well as the duration and total incidences of seroma.
