Enhanced Recovery After Surgery (ERAS) Program Attenuates Stress and Accelerates Recovery in Patients After Radical Resection for Colorectal Cancer: A Prospective Randomized Controlled Trial

Background The aim of this trial was to compare the Enhanced Recovery After Surgery (ERAS) program with conventional perioperative management in patients who underwent radical resection for colorectal cancer. Methods A combination of evidence-based and consensus methodology was used to develop the ERAS protocol. Five hundred ninety-seven consecutive patients who underwent elective colorectal resection were randomized to either the ERAS ( n = 299) or the control group ( n = 298). Outcomes relating to nutrition and metabolism index, stress index, and recovery index were measured and recorded. Results Demographic and operative data were similar between the two groups. Patients in the ERAS group showed improved nutritional status when compared with those of the control group. On postoperative day (POD) 1, the HOMA-IR (insulin resistance index) of the ERAS group was lower than that of the control group ( p
