Purpose Abnormalities in esophageal motor function underlie various symptoms i n the pediatric population. Manometry remains an important tool for studying eso phageal motor function, whereas its analyses have been conducted with considerab le subjective interpretation. The usefulness of videomanometry with topographic analysis was examined in the current study. Methods Videomanometry was conducted in 5 patients with primary gastroesophageal reflux disease (GERD), 4 with posto perative esophageal atresia (EA), 1with congenital esophageal stenosis (CES), an d 1 with diffuse esophageal spasms (DES). Digitized videofluoroscopic images wer e recorded synchronously with manometric digital data in a personal computer. Ma nometric analysis was conducted with a view of concurrent esophageal contour and bolus transit. Results Primary GERD patients showed esophageal flow proceeding into the stomach during peristaltic contractions recorded manometrically, wherea s patients with EA/CES frequently showed impaired esophageal transit during defe ctive esophageal peristaltic contractions. A characteristic corkscrew appearance and esophageal flow in a to-and-fro fashion were seen with high-amplitude sy nchronous esophageal contractions in a DES patient. The topographic analysis sho wed distinctive images characteristic of each pathological condition. Conclusion s Videomanometry is helpful in interpreting manometric data by analyzing concurr ent fluoroscopic images. Topographic analyses provide characteristic images refl ecting motor abnormalities in pediatric esophageal disease.
