Summary

False feeding refers to promoting gastrointestinal peristalsis by seeing, smelling, chewing, and tasting food, not getting food into the gastrointestinal tract. Postoperative sham feeding uses gum to promote the healing of gastrointestinal peristalsis. Although not fully understood, the physiological theory underlying gum chewing (fake feeding) to stimulate peristalsis and reduce postoperative intestinal recovery time is that the oral and chewing stimulation provided by chewing gum stimulates a neurohumoral reflex that increases gastrointestinal fluid secretion. This increases gastrointestinal motility. In addition, oral stimulation and chewing can stimulate the vagus nerve, which is also involved in promoting peristalsis. Finally, none of the existing theories adequately explain the effect of chewing/gum chewing on reducing postoperative inflammation in the gut, which may result in a reduced incidence of postoperative infection. In previous studies, physiological changes associated with gum appear to promote normal gastrointestinal function and subsequent postoperative/anesthetic recovery. Although many studies have been conducted to examine the effectiveness of chewing gum in patients undergoing colorectal resection, the results have been inconsistent. This can be attributed to differences in intestinal injuries affecting bowel function, differences in time under anesthesia and differences in anesthetics or pain control agents used for pain control affecting bowel function, and recovery time of peristalsis. Given the many factors known to affect postoperative ileus, chewing gum as an intervention remains a safe, accessible, and inexpensive option that remains to be explored.

Conditions

  • Postsurgical Ileus

Interventions

OTHER

gum chewing

For the patients in the experimental group, sugar-free xylitol gum containing 1.2-1.37 grams of xylitol per piece, available in the market, will be used. Participants in the experimental group will start chewing gum on the first postoperative day and will be allowed to chew a single piece of gum 3 times a day at 9:00, 14:00 and 19:00, respectively, for 15 minutes. The gum will be given to the participants regularly by a researcher until the first reported flatulence.
