Enhanced recovery after surgery (ERAS) protocol improves patient outcomes in free flap surgery for head and neck cancer

Abstract

BackgroundIn recent years, enhanced recovery after surgery (ERAS) guidelines have been developed to optimize pre-, intra-, and postoperative care of surgical oncology patients. The aim of this study was to compare management outcome of patients undergoing head and neck cancer (HNC) surgery with free flap reconstruction at our institution before and after the implementation of the ERAS guidelines.MethodsThis retrospective study comprised 283 patients undergoing HNC surgery with free flap reconstruction between 2013 and 2020. Patients operated before and after the implementation of the ERAS protocol in October 2017 formed the pre-ERAS group (n = 169), and ERAS group (n = 114), respectively.ResultsIn the pre-ERAS group the mean length of stay (LOS) and intensive care unit length of the stay (ICU–LOS) were 20 days (range 7–79) and 6 days (range 1–32), and in the ERAS group 13 days (range 3–70) and 5 days (range 1–24), respectively. Both LOS (p < 0.001) and ICU–LOS (p = 0.042) were significantly reduced in the ERAS group compared to the pre-ERAS group. There were significantly fewer medical complications in the ERAS group (p < 0.003). No difference was found between the study groups in the surgical complication rate or in the 30-day or 6-month mortality rate after surgery.ConclusionsWe found reduced LOS, ICU–LOS, and medical complication rate, but no effect on the surgical complication rate after implementation of the ERAS guidelines, which supports their use in major HNC surgery.
