This is a prospective, single-center, crossover study comparing EndoFLIP measurements obtained in two patient positions, supine and left lateral decubitus, in pediatric and young adult patients. The Endoluminal Functional Lumen Imaging Probe (EndoFLIP) is an FDA-approved device for patients aged 5 and older that utilizes high-resolution impedance planimetry and volume-controlled distension to assess esophagogastric junction function. Currently, no standardized positioning protocol exists, and proceduralists perform EndoFLIP based on individual preference, either supine or left lateral decubitus. This variability may introduce measurement inconsistencies, particularly when comparing preoperative and postoperative assessments performed in different positions.
The Endoluminal Functional Lumen Imaging Probe (EndoFLIP) is an FDA-approved device for patients aged 5 years and older and it utilizes high-resolution impedance planimetry and volume-controlled distension to evaluate the GI lumen including the esophagogastric junction. EndoFLIP has become an invaluable tool in pediatric gastroenterology helping to characterize various luminal conditions including but not limited to esophageal stenosis and compression, screening for dysmotility, guiding esophageal dilation through the selection of the optimal dilator size, among others. Despite its increasing…
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. * particip…
