Objective:
Postoperative ileus is common after colorectal resection and can prolong hospital stay. Gum chewing, a type of sham feeding, may to stimulate gut motility via cephalic-vagal stimulation, and thereby reduce the length of ileus. This study aimed to determine whether gum chewing in the immediate postoperative period facilitated recovery from ileus following resection for left-sided colorectal cancer.
Methods:
In a prospective randomized control trial, 38 patients undergoing open surgery for left-sided colorectal cancer were allocated to standard postoperative care (control group, n = 19) or to standard postoperative care plus the immediate use of chewing gum (treatment group, n = 19).
Result:
Control patients passed flatus by mean of 2.7 days (SD 1.0) and faeces by 3.9 days (SD 1.5); for the treatment group, this was 2.4 days (SD 1.0) and 3.2 days (SD 1.5) respectively, (NS, P = 0.56 and P = 0.38). Length of hospital stay was 11.1 days (SD 7.3) in control group and 9.4 days (SD 2.5) in the treatment group (NS, P = 0.75).
Conclusion:
The addition of gum chewing to a standardized postoperative regimen did not reduce the period of postoperative ileus or shorten length of stay following open surgery for left-sided colorectal cancer.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
