Impact of Patient Position on EndoFLIP Measurements in Kids and Young Adults

Official title: Impact of Body Positioning on EndoFLIP Measurements: A Comparative Study of Supine and Left Lateral Decubitus Positions

Run by Johns Hopkins University · NCT07780981 · Data updated 2026-11-12

This study tests whether EndoFLIP measurements differ when patients are in the supine versus left-side position during the procedure.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are 5–21 years old, scheduled for a clinically indicated EndoFLIP at Johns Hopkins Children’s Center, and able to provide consent/assent.

Probably not a fit

Patients who do not show a difference between positions or do not undergo comparative measurements may not gain direct benefits.

What this trial studies

This prospective, single-center crossover study enrolls children and young adults aged 5 to 21 undergoing EndoFLIP at Johns Hopkins. Each participant will have measurements taken in both the supine and left lateral decubitus positions to determine how position affects EndoFLIP results. The trial uses a standardized EndoFLIP protocol and compares the two positions to reduce variability in esophagogastric junction assessment. The aim is to improve consistency for preoperative and postoperative evaluations in pediatric and young adult patients. No treatment beyond the EndoFLIP procedure itself is involved.

Why it matters

Potential benefit: If position-related differences are identified, clinicians can standardize EndoFLIP positioning to improve measurement consistency.

How similar studies have gone: There are no published studies comparing EndoFLIP measurements by patient position, making this investigation novel.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* must be between 5 years and 21 years of age at the time of the procedure, which is within the FDA-approved age range for EndoFLIP use.
* participants must be scheduled to undergo a clinically indicated EndoFLIP procedure at Johns Hopkins Children's Center.
* participants must have a parent or legal guardian who is able to provide written informed consent in English, or with the assistance of translation services for non-English speakers.
* participants who are of appropriate age and developmental capacity must be able to provide assent for study participation.
* participants must be candidates for general anesthesia as determined by the anesthesia team.

Exclusion Criteria:

* patients younger than 5 years of age or 22 years of age and older will be excluded.
* patients who have contraindications to EndoFLIP will be excluded, including situations where upper endoscopy is generally contraindicated such as known or suspected gastrointestinal perforation, hemodynamic instability, severe coagulopathy, or inability to safely undergo general anesthesia.
* patients who cannot be safely positioned in both supine and left lateral decubitus positions due to medical or anatomical considerations will be excluded.
* pregnant patients will be excluded. Pregnancy status will be determined by patient or guardian report and, when clinically indicated, by urine or serum pregnancy testing per institutional protocols for patients of childbearing potential.
* patients whose parent or legal guardian declines to provide informed consent or patients who decline to provide assent when age-appropriate will be excluded.
* patients for whom the proceduralist or anesthesia team determines that participation in the research protocol would pose additional risk beyond routine clinical care will be excluded.
