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 .
Compliance with enhanced recovery after surgery criteria and preoperative and postoperative counselling reduces length of hospital stay in colorectal surgery: results of a randomized controlled trial
The aim of this r and omized clinical trial was to compare patients treated using a multimodal approach [ enhanced recovery after surgery ( ERAS ) ]  , with a special focus on counselling , to patients treated in a st and ard conventional care pathway , who underwent elective colorectal resection
In predefined subgroup analyses , findings did not vary by surgical approach ( open vs laparoscopic ) or colorectal condition .
