In predefined subgroup analyses , findings did not vary by surgical approach ( open vs laparoscopic ) or colorectal condition .
CONCLUSIONS : Enhanced recovery protocol s for adults undergoing colorectal surgery improve patient outcomes with no increase in adverse events .
Evidence was insufficient regarding which components , or component combinations , are key to improving patient outcomes .
BACKGROUND : Enhanced surgical recovery protocol s are design ed to reduce hospital length of stay and health care costs .
OBJECTIVE : This study aims to systematic ally review and summarize evidence from r and omized and controlled clinical trials comparing enhanced recovery protocol s versus usual care in  adults undergoing elective colorectal surgery with emphasis on recent trials , protocol components , and subgroups for surgical approach and colorectal condition .
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 r and omized 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 < 0.001 ) . The cortisol level of the control group was elevated on both POD 1 ( p = 0.007 ) and POD 5 ( p = 0.002 ) compared to the preoperative level . However , the cortisol level of the ERAS group was not increased until POD 5 ( p = 0.001 ) . Reduced levels of TNF-α , IL-1β , IL-6 , and IFN-γ in the ERAS group indicated less postoperative stress responses . In addition , ERAS was associated with accelerated recovery of gastrointestinal function . The postoperative length of stay ( p < 0.001 ) and expense ( p < 0.001 ) for the ERAS group were reduced in comparison to the controls . Twenty-eight cases in the control group and twenty-nine in the ERAS group suffered complications , which was not significantly different . Conclusion The ERAS protocol attenuates the surgical stress response and accelerates postoperative recovery without compromising patient safety
