    Abstract:
    BACKGROUND: Latissimus dorsi myocutaneous (LD) flaps are widely used in breast reconstruction surgery. However, seromas often form postoperatively at the donor site as a complication. This study aimed to determine the impact of different electrocautery modes during flap elevation, with or without subsequent quilting sutures, on postoperative seroma formation. METHODS: Subjects were 112 patients who underwent immediate breast reconstruction with LD flaps after breast-conserving surgery between April 2015 and January 2019. Group A consisted of 21 patients who underwent LD flap elevation using the fulgurate mode, and group B consisted of 25 patients who underwent flap elevation using the lower power, pure cut mode. Group C consisted of 66 patients who underwent flap elevation with the lower power, pure cut mode combined with quilting sutures for wound closure. RESULTS: Mean 1-week postoperative back drain volume and the mean number of days to drain removal in group B were significantly reduced relative to those in group A (group A, 752.3 mL and 16.9 days, respectively; group B, 552.2 mL and 10.6 days, respectively; P < 0.001 for both). Group C, which included quilting sutures, had even lower values than group B (459.7 mL and 7.4 days, respectively; group B vs group C: P = 0.03 and P < 0.001, respectively). Significant differences were observed between groups for postoperative seroma formation at the flap donor site (group A, 16 [76.2%] of 21 patients; group B, 11 [44%] 25 patients; group C, 4 [6.1%] of 66 patients; A vs B: P < 0.001, B vs C: P < 0.001). CONCLUSIONS: The use of low power, pure cut mode for LD flap harvest, combined with quilting sutures, effectively shortened the time to drain removal and suppressed seroma formation. Given that specialized devices and materials are not required, this combination may reduce both patient burden and medical costs.
