Utility of functional lumen imaging probe in esophageal measurements and dilations: a single pediatric center experience

Background Pediatric esophageal stenosis can be challenging to manage due to post-dilation tissue response involving fibroblast activity resulting in scar reformation. The functional lumen imaging probe (FLIP) uses high-resolution impedance planimetry to measure key luminal parameters during a volume-controlled distension. We sought to evaluate the safety as well as possible settings of EndoFLIP and EsoFLIP in the pediatric population.
