Compared with the conventional perioperative intervention group , the fast-track protocol combined with laparoscopy could shorten the time to the first flatus ( @ h vs @ h , P = @ ) and first defecation ( @ h vs @ h , P = @ ) after operation , accelerate the decrease of white blood cell count ( P < @ ) , inhibit body temperature augmentation ( P < @ ) and reduce postoperative complication rate ( @ % vs @ % , P = @ ) .
