Positive effects of the enhanced recovery after surgery (ERAS) protocol in DIEP flap breast reconstruction

Abstract

Background: Enhanced recovery after surgery protocols are successfully implemented in different surgical specialties, but a specific protocol for autologous breast reconstruction is missing. The aim of this study was to determine whether an enhanced recovery after surgery (ERAS) protocol contributes to a reduced length of stay without an increase in postoperative complications for patients undergoing a DIEP flap breast reconstruction.

Materials en methods: The effect of the ERAS protocol was examined using a single-center patient-control study comparing two groups of patients. Patients who underwent surgery between November 2017 and November 2018 using the ERAS protocol were compared with a historical control group (pre-ERAS) who underwent surgery between November 2016 and November 2017. The primary outcome measure was hospital length of stay. Secondary outcome measures were postoperative pain and postoperative complications.

Results: 152 patients were included (ERAS group, n = 73; control group, n = 79). Mean hospital length of stay was significantly shorter in the ERAS group than in the control group (5 vs. 6 days, p < 0.001). The average pain score was 1.73 in de the ERAS group compared to 2.17 in the control group (p = 0.032). There were no significant differences between the groups in postoperative complications. The ERAS group experienced less constipation (41 vs. 25 patients, p = 0.028).

Conclusion: An enhanced recovery after surgery protocol contributes an accelerated postoperative recovery of patients undergoing a DIEP flap breast reconstruction. In this study a significant decrease was found in hospital length of stay, patient-reported pain score and adverse health issues.
