Enhanced recovery after surgery and mini-invasive approaches in rectal cancer surgery - short-term outcomes.

INTRODUCTION

The aim of this study was to evaluate short-term outcomes of patients undergoing mini-invasive rectal resection within an ERAS (enhanced recovery after surgery) protocol.

METHODS

A prospectively managed database of patients undergoing rectal operations performed at our department between January 2015 and April 2020 was retrospectively analyzed. An ERAS protocol was implemented into clinical practice at our department in April 2016 and mini-invasive rectal procedures in May 2016. The ERAS group consisted of all patients who underwent mini-invasive rectal resections or amputations within the ERAS protocol. The control group consisted of patients who underwent open procedures and received standard perioperative care. The extracted data included basic patient characteristics, surgical data, postoperative recovery parameters, 30-day morbidity, length of postoperative stay and 30-day rehospitalization.

RESULTS

A total of 110 patients were included in the study: 67 patients in the ERAS group and 43 in the control group. Within the ERAS group 47 patients underwent robotic procedures and 20 had laparoscopic procedures. Patients in the ERAS group had significantly better clinical and laboratory recovery parameters except for postoperative nausea and vomiting. A significantly lower incidence of paralytic ileus (20.9% vs. 3%) and a shorter length of postoperative stay (13 days vs. 9 days) was found in the ERAS group. The rehospitalization rate and 30-day morbidity were not different between the ERAS and control group.

CONCLUSIONS

Implementation of the ERAS protocol in combination with mini-invasive approaches leads to better short-term postoperative outcomes after rectal surgery.
