Poster Session II A330 ANALYSIS OF ESOPHAGEAL CHARACTERISTICS IN CHILDREN WITH ESOPHAGEAL ATRESIA USING FLIP PANOMETRY
Abstract
Abstract Background Esophageal atresia (EA) is the most common congenital abnormality of the oesophagus and is associated with long-term complications including dysmotility, dysphagia, gastroesophageal reflux disease, and eosinophilic oesophagitis (EoE). Aims To assess esophageal mechanical and functional properties in children with EA and to evaluate the utility of Functional Lumen Imaging Probe (FLIP) panometry in this patient population. Methods We retrospectively analysed FLIP panometry studies performed during endoscopic follow-up in EA patients. An 8- or 16-cm balloon was selected according to patient height. Where possible, we applied the 2025 Dallas criteria for data analysis. Measurements included esophagogastric junction (EGJ) characteristics, distensibility plateau (DP), compliance over 8cm and secondary peristalsis. Results Thirty-two children with EA were included, with a median age of 7,4 years (9 months – 17 years). DP corresponded with the anastomosis in most patients, with a median DP of 14mm and a distensibility index (DI) at DP of 4,0mm^2/mmHg. Both DP and DI at DP correlated with age and height. A DP of less than 15mm was associated with food impaction, while DI at DP was correlated with both dysphagia and food impaction. Secondary peristalsis was absent in 34%, diminished in 22%, normal in 28%, disordered/impaired in 13%, and spastic in 3%. A trend towards reflux oesophagitis was observed in patients with absent or diminished peristalsis. An EGJ DI of…
