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 .
Fast-Track Surgery Improves Postoperative Clinical Recovery and Immunity After Elective Surgery for Colorectal Carcinoma: Randomized Controlled Clinical Trial
Background Few clinical studies or r and omized clinical trial results have reported the impact of fast-track surgery on human immunity . This study aim ed to investigate the clinical and immune impact of fast-track surgery in colorectal cancer patients undergoing elective open surgery . Methods A controlled r and omized clinical trial was conducted from November 2008 to January 2009 with a 1-month postdischarge follow-up . A total of 70 patients with colorectal carcinoma requiring colorectal resection were r and omized into two groups : a fast-track group ( 35 cases ) and a conventional care group ( 35 cases ) . All included patients underwent elective open colorectal resection with combined tracheal intubation and general anesthesia .  Clinical parameters and markers of immune function were evaluated in both groups postoperatively . Results In all , 62 patients completed the study : 32 in the fast-track group and 30 in the conventional care group . Our findings revealed a significantly shorter postoperative hospital stay and faster return of gastrointestinal function in patients undergoing fast-track rehabilitation . In addition , we found a quicker response of white blood cells in the fast-track group than in the conventional care group . We also found that blood levels of globulin , immunoglobulin G , and complement 4 on postoperative day 3 were higher in the fast-track group than in the conventional care group . Conclusions Fast-track surgery accelerates clinical recovery and improves postoperative immunity after elective open surgery for colorectal carcinoma
