Study summary

Traditional postoperative care has been challenged recently to improve and speedup recovery (including the return of bowel function) such that patients can be discharged to home more quickly. This approach includes earlier mobilization of the patient, and introducing solid food sooner. Additionally, there is evidence in adults to suggest that "sham feeding" by chewing gum may also speed up bowel recovery so the patient may tolerate a solid diet earlier.

The aim of this study is to determine if gum chewing can enhance bowel recovery in children who undergo abdominal surgery.

Read the detailed description

After intestinal surgery, many patients suffer from a "postoperative ileus" (POI). The cause is multifactorial and can be attributed to surgery itself, the lingering effect of the anesthetic, the use of narcotics and decreased mobility of the patient.

An ileus can delay the time to full diet, thus lengthening the hospital stay of the patient - sometimes up to several weeks.

There is evidence that early drinking/eating and increased mobility may accelerate the return of bowel function. "Fast-tracking" is well documented in the adult literature; protocols have been put in place to enhance GI tract recovery and thus decrease the morbidity of a prolonged hospital stay and ileus. "Fast-tracking" has been done in pediatric patients but not in a large RCT for abdominal surgery.

What researchers measure

Primary outcomes

  1. Composite outcome: first flatus, first bowel movement, first solid oral intake (any)

    Documented by nurse, patient or caregiver

    Time frame: From time of leaving the operating room (time zero) until the time of event (first bowel movement, first flatus, first oral intake) or date of death of any cause, whichever comes first, assessed up to 30 days, measured in hours

Secondary outcomes

  1. Length of stay

    From day admission to day of discharge

    Time frame: From day of entering the operating room (time zero) until the time of event (day of discharge) or date of death of any cause, whichever comes first, assessed up to 30 days, measured in days

  2. Readmission

    Need for readmission within 30 days of discharge

    Time frame: From day of discharge (time zero) until the time of event (day of readmission) or date of death of any cause, whichever comes first, assessed up to 30 days, measured in days

  3. Swallowing/aspiration of gum

    Measured as yes/no

    Time frame: From day of entering the operating room (time zero) until the time of event (swallowing/aspiration of gum) or date of death of any cause, whichever comes first, assessed up to 30 days, measured as yes/no

  4. Allergic reaction/adverse reaction to gum

    Measured as yes/no

    Time frame: From day of entering the operating room (time zero) until the time of event (allergic reaction/adverse reaction to gum) or date of death of any cause, whichever comes first, assessed up to 30 days, measured as yes/no

  5. Re-operation

    Measured as yes/no

    Time frame: From day of entering the operating room (time zero) until the time of event (Re-operation) or date of death of any cause, whichever comes first, assessed up to 30 days, measured as yes/no

  6. Need for prokinetic/anti-reflux medication

    Measured as yes/no if need for additional medications to facilitate return of bowel function

    Time frame: From time of leaving the operating room (time zero) until the time of event (ordering of prokinetic/anti-reflux medication) or date of death of any cause, whichever comes first, assessed up to 30days, measured in hours

  7. Narcotic use

    Quantity of narcotics consumed (mg/kg total)

    Time frame: From time of leaving the operating room (time zero) until the time of event (ordering of narcotic medication) or date of death of any cause, whichever comes first, assessed up to 30days, measured in hours

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2018 (actual). Primary completion is estimated for Dec 2024, 72 months after the start.

Of 40 non-industry interventional studies with no phase under Ileus, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 53. This study's planned 72 months is above that.

Counting every sponsor, half of 40 studies reached it within 19 months; a quarter within 7 and three quarters within 53.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 2, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
