How Body Position Affects Esophageal Measurements in Children

This trial is testing whether the position your child lies in during an esophageal imaging procedure affects the measurements doctors get. Researchers will use a device called EndoFLIP — an FDA-approved tool that takes detailed pictures of the esophagus and the connection between the esophagus and stomach — while your child is in two different positions (lying flat on their back, and lying on their left side). The goal is to figure out if one position gives more reliable or consistent results than the other.

Right now, different doctors use this imaging tool in different ways depending on their preference, and there's no standard approach. This variation could lead to different results for the same patient, which makes it hard to track whether a child's condition is improving or to compare measurements over time. This study exists to figure out which position gives the most reliable measurements so doctors can all use the same method.
