Chewing Gum for Postoperative Ileus
(GUM_1 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether chewing gum can help children recover faster after abdominal surgery by stimulating bowel movement. Chewing gum may trick the stomach, speeding up recovery so children can eat solid food and return home sooner. The trial compares children who chew gum with those who do not, alongside usual care. Suitable participants are children who have undergone abdominal surgery and are hospitalized for more than a day. As an unphased trial, this study offers a unique opportunity for children to potentially experience faster recovery and contribute to innovative research.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that gum chewing is safe for enhancing bowel recovery in children?
Research has shown that chewing gum after surgery is safe. Studies have found it poses very little risk to patients and is generally well-accepted. Chewing gum may aid recovery by stimulating bowel function sooner, potentially leading to a quicker return to normal eating and a shorter hospital stay. Overall, chewing gum is a safe option for post-surgery recovery.12345
Why are researchers excited about this trial?
Unlike the standard treatments for postoperative ileus, which often include medications to manage pain and promote bowel movement, gum chewing offers a simple, non-pharmacological approach. Researchers are excited about this technique because it leverages the body's natural reflexes: chewing gum stimulates the digestive system by mimicking the act of eating, which can help jumpstart bowel activity after surgery. This method is not only potentially effective but also avoids the side effects associated with medication. Plus, it's easy to implement and could enhance recovery while reducing the need for additional drugs.
What evidence suggests that gum chewing is effective for postoperative ileus?
Research has shown that chewing gum can help the bowels start working sooner after surgery, reducing recovery time. In this trial, participants in the gum-chewing group will receive standard pharmacologic treatment and post-operative care, along with chewing one piece of sugarless gum three times daily for 1 hour each. Some studies suggest that gum chewers may leave the hospital sooner. For instance, one study found that 27% of gum chewers experienced delayed bowel recovery, compared to 48% of those who didn't chew gum. However, not all studies agree, and some found little effect, especially in surgeries like colectomies. Overall, chewing gum is safe and might help speed up recovery by getting the bowels moving again after surgery.16789

Are You a Good Fit for This Trial?
This trial is for children aged 4 or older who are undergoing abdominal surgery and expected to stay in the hospital for over 24 hours. It's not suitable for kids under 4, those unable to chew gum/swallow due to medical conditions, or if they/their parents can't consent or follow instructions.Inclusion Criteria

Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants undergo abdominal surgery and receive usual post-operative care. In the experimental group, participants chew sugarless gum three times daily for 1 hour each.
Follow-up
Participants are monitored for safety and effectiveness, including bowel recovery and any adverse reactions to gum chewing.
What Are the Treatments Tested in This Trial?
Interventions
- Gum chewing
Trial Overview
The study tests whether chewing gum after abdominal surgery helps children recover bowel function faster so they can eat solid foods sooner. The idea is that 'sham feeding' with gum might speed up this recovery process.
