Does Chewing Gum After Elective Laparoscopic Colectomy Surgery Decrease Ileus?

The incidence of ileus after laparoscopic colectomy continues to pose complications for the patient, staff, and the healthcare system. Postoperative ileus remains a source of morbidity and a major determinant of length of stay after abdominal surgery. Clinicians have devised strategies that minimize postoperative ileus. Gum chewing, an inexpensive intervention, is theorized to activate the cephalic- vagal reflex and increase the production of gastrointestinal hormones associated with bowel motility. Four studies examining gum chewing as an intervention to prevent ileus were found. These relatively few studies have demonstrated inconsistencies. Because of the small sample size of the four studies and the inconsistencies of the results, there is not enough evidence to change practice. There are no indications of risks associated with gum chewing as an adjunct therapy along with standard postoperative interventions. The purpose of this prospective, randomized control study is to examine if chewing gum in adult patients after elective laparoscopic colectomy decreases ileus compared with standard post-operative care. Patients will be randomized by weeks admitted and the patients in the gum chewing group (intervention group) will chew one stick of gum the first post-operative day, after the nasogastric tube is removed or if they patient does not have a nasogastric tube, with the head of bed elevated a minimum of 30 degrees for 30 minutes, three times a day at set intervals: 0900, 1400, and 2100. The gum will be kept in the Accudose cabinet and distributed by the medication nurse. The gum chewing regimen will continue until the first bowel movement. All patients in the non-intervention group will receive standard preoperative and postoperative regimens. Patient demographics that will be collected include gender, age, current medical condition, pre-operative medications, type of surgery, operative duration in minutes, anesthesia duration in minutes, estimated operative blood loss, whether they had an epidural or a PCA, date and time nasogastric tube was discontinued, length of stay, date of discharge, complications, and whether or not they had an ileus. Patients (if appropriate) and nurses will be instructed on how to complete the bedside bowel record to the nearest hour.
