Variables associated with length of stay in patients undergoing mastectomy and delayed-immediate breast reconstruction with tissue expander.

Delayed-immediate reconstruction with the placement of tissue expanders at the time of mastectomy is a common approach to breast reconstruction. The purpose of this study was to identify variables associated with increased LOS in patients that underwent bilateral or unilateral mastectomy with tissue expander placement. Bilateral procedure, a diagnosis of anxiety or depression, and age >55 years were independently associated with increased LOS. More recent year of surgery and Friday surgery were associated with decreased LOS.
