Surgery is one of the most frequent treatments of colorectal cancer. However, delayed restoration of intestinal motility is a common phenomenon in patients who undergo colorectal surgery, and may reduce comfort, prevent the early hospital discharge of patients and increase healthcare costs. Gum chewing is a kind of safe and easily accessible sham feeding to stimulate intestinal motility. In addition, prediction models were used to estimate the risk of delayed restoration of intestinal motility after colorectal surgery. Thus, this study is an External Controlled trial that will determine whether stratified application of gum chewing by risk prediction model will enhance restoration of intestinal motility and reduce healthcare costs in paitents undergoing open or laparoscopic colorectal surgery.

gum chewing
Dietary supplementParticipants allocated to chewing gum will be instructed to chew commercially available sugar-free gum (Extra \& Reg, Wm. Wrigley Jr. Co., Ltd., Shanghai, China) three times daily from the first postoperative morning until oral dietary intake. They were instructed to chew the piece of gum for at least 10 minutes.
