Measuring Normal Esophageal Flexibility in Children Using EndoFLIP (EndoFLIP)

2. September 2026 aktualisiert von: Brett J. Hoskins, Indiana University

Prospective Measurement of Normative Esophageal Distensibility Using EndoFLIP in Asymptomatic Children

This study will measure normal esophageal flexibility (distensibility) in children using the Endoluminal Functional Lumen Imaging Probe (EndoFLIP). Children who are already undergoing anesthesia for clinically indicated colonoscopy with colonic motility catheter placement and who have no history or symptoms of esophageal disease will undergo a brief EndoFLIP measurement lasting approximately 3-5 minutes before their scheduled procedure. The information collected will help establish preliminary normal pediatric reference values for esophageal distensibility, which may improve the evaluation of children with esophageal disorders in the future.

Detaillierte Beschreibung

The Endoluminal Functional Lumen Imaging Probe (EndoFLIP) is an FDA-cleared device that measures the size, pressure, and flexibility (distensibility) of the esophagus. In adults, EndoFLIP measurements are routinely used to evaluate esophageal motility disorders such as achalasia. However, normal reference values for children have not been established, and pediatric interpretation currently relies largely on adult data.

The purpose of this prospective, single-center observational study is to generate preliminary normative pediatric EndoFLIP measurements. One hundred children between 5 and younger than 18 years of age who are undergoing clinically indicated colonoscopy with colonic motility catheter placement under general anesthesia will be enrolled. Eligible participants must have no history of esophageal disease or surgery and no symptoms suggestive of upper gastrointestinal disease.

Immediately before the scheduled colonoscopy and motility catheter placement, an EndoFLIP catheter will be inserted through the mouth and positioned across the lower esophageal sphincter. Measurements of esophageal diameter, cross-sectional area, pressure, compliance, and distensibility index will be obtained at standardized balloon fill volumes (20-60 mL). The EndoFLIP assessment requires approximately 3-5 minutes and does not require an upper endoscopy or any additional anesthesia. After the measurements are completed, the catheter is removed and the planned clinical procedure proceeds as scheduled. No additional study visits or follow-up are required.

The primary objective is to establish preliminary normative pediatric values for esophageal distensibility and related biomechanical parameters. Secondary analyses will evaluate associations between EndoFLIP measurements and participant age, height, weight, and body mass index. These data are intended to improve interpretation of pediatric EndoFLIP studies and support future research and clinical care for children with esophageal disorders.

Intervention / Behandlung
Sonstiges: Asymptomatic Children Undergoing EndoFLIP Assessment
Children 5 to younger than 18 years of age undergoing clinically indicated colonoscopy with colonic motility catheter placement under general anesthesia who have no history or symptoms of esophageal disease. Participants undergo a single 3-5 minute EndoFLIP assessment before the scheduled procedure to measure esophageal distensibility index, diameter, cross-sectional area, compliance, and pressure for development of preliminary normative pediatric reference values.
Gerät: Endoluminal Functional Lumen Imaging Probe (EndoFLIP)
The Endoluminal Functional Lumen Imaging Probe (EndoFLIP) is an FDA-cleared impedance planimetry device used to measure esophageal diameter, cross-sectional area, intraballoon pressure, distensibility index, and compliance. In this study, the EndoFLIP catheter is inserted orally during general anesthesia immediately before clinically indicated colonoscopy with colonic motility catheter placement. Measurements are obtained over approximately 3-5 minutes at standardized balloon fill volumes of 20-60 mL, after which the catheter is removed and the planned clinical procedure proceeds. The EndoFLIP assessment is performed solely for research purposes to establish preliminary normative pediatric esophageal biomechanical reference values.
