    Study Notes

    Introduction

    • Hemostatic agents are increasingly used in surgery to reduce bleeding complications
    • Hematomas and seromas are common post-operative complications in breast cancer surgery, including mastectomy and reconstruction
    • Oncoplastic surgery (OPS) combines breast cancer and plastic surgery techniques for optimal outcomes
    • There is limited research on the use of hemostatic agents in OPS and breast surgery, so this study investigated their effectiveness
    • The study aimed to evaluate the frequency of post-operative bleeding complications and the duration of Jackson-Pratt (JP) drain use in breast surgeries with and without hemostatic agents

    Methods

    • A retrospective chart review was conducted on patients who underwent breast cancer surgery between January 2015 and September 2020
    • The study included surgeries such as oncoplastic breast surgery, mastectomy with or without reconstruction, and expander to implant exchange
    • Data collected included the indication for surgery, type of operation, use of hemostatic agent (either EVICEL® or HEMOBLASTÔ Bellows), length of follow-up, time to JP drain removal, and post-operative complications (seroma, hematoma, or operating room (OR) takeback)
    • The study followed a consecutive experience where no hemostatic agent was initially used, then followed by the use of EVICEL®, and lastly HEMOBLASTÔ Bellows
    • Lidocaine with epinephrine was used for postoperative analgesia, and surgeons ensured patients were not hypotensive to minimize bleeding later
    • JP drains were removed when output was less than 30 cc/day for 2 consecutive days, with output compared between groups using Welch’s t-test
    • Post-operative complications were compared using Fisher’s exact test, with statistical significance defined as P <.05

    Results

    • The use of hemostatic agents (EVICEL® or HEMOBLASTÔ Bellows) significantly reduced the time to JP drain removal and overall bleeding complications compared to no hemostatic agent
    • HEMOBLASTÔ Bellows (CP) showed a more pronounced effect, especially in the mastectomy group, with a lower rate of seroma, hematoma, and return to OR
    • CP also significantly decreased JP drain duration compared to the no hemostatic agent group in oncoplastic, mastectomy, and expander exchange procedures
    • Subgroup analysis revealed no hematomas, seromas, or return to OR for oncoplastic and expander exchange procedures in the CP group compared to the EVICEL® (FS) group, which had a higher rate of seroma
    • While the CP group had a lower rate of seroma and OR takeback after mastectomy compared to FS, these differences were not statistically significant
