- Background: Placement of a closed suction drain is a common cause of patient complaints, such as postoperative pain or discomfort following immediate expander-implant breast reconstruction. This study aims to identify factors that affect drainage volume, time to drain removal, and seroma formation. Methods: A retrospective chart review of prospectively collected data was conducted on patients who underwent immediate expander-implant breast reconstructions following nipple-sparing or skin-sparing mastectomy without skin excision (nipple areolar complex excision only) between February 2010 and April 2015. Daily drainage volume was measured until the drain was removed. Eight independent variables, including acellular dermal matrix (ADM) usage and inflation ratio (the rate of initial inflation volume to mastectomy weight) were analysed by univariable and multivariable analyses. Results: A total of 162 breasts in 148 patients were included in this study. The inflation ratio did not influence the drain amount or days to drain removal. Although the use of ADM was significantly associated with increased drainage during the first 5 postoperative days (p = 0.015), it was not significant when adjusted for time. Old age, larger expander size, and larger drain amount on the first postoperative day were predictors for longer days to drain removal (p < 0.001). Old age had a trend toward higher risk of seroma formation that approached statistical significance (p = 0.057). Conclusions: The use of ADM and initial inflation ratio do not influence days to drain removal or seroma formation. A longer period of drain placement is expected when a larger expander is used or in elderly patients. © 2017 Acta Chirurgica Scandinavica Society
