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

BACKGROUND

Seroma is a common complication in prepectoral breast reconstruction. PICO 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 PICO 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 (PICO : 37 and non-PICO patients: 23). The overall incidence of complications, major seromas, and frequency of reoperations were lower in the PICO group compared to the non-PICO 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 PICO 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 PICO dressing status and mastectomy volume. The total number of patients who developed seroma was statistically correlated with age, PICO dressing status, and mastectomy volume.

CONCLUSIONS

PICO 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.
