Esophageal Motility Disorders in Patients With Esophageal Barium Residue After Videofluoroscopic Swallowing Study

초록

Objective To investigate esophageal motility disorders in patients with esophageal residual barium on chest x-rays after videofluoroscopic swallowing studies (VFSS) through high-resolution esophageal manometry (HREM). Methods We reviewed the records of 432 patients who underwent VFSS from September 2019 to May 2021, and 85 patients (19.7%) with large residual barium (diameter al cm) were included. As a result of HREM, motility disorders were classified as major or minor motility disorders according. Esophagogastroduodenoscopy and chest computed tomography results available were also reviewed. Results Among 85 patients with large residual barium in the esophagus, 16 patients (18.8%) underwent HREM. Abnormal esophageal tnotilities were identified in 68.8% patient: three patients (18.8%) had major motility disorders-achalasia (n=1), esophagogastric junction (EGJ) outflow obstruction (n=2)-and eight patients (50%) had minor motility disorders-ineffective esophageal motility (n=7), fragmented peristalsis (n=1). In those with normal esophageal motility, three patients of esophageal structure disorders (18.8%)-esophageal cancer (n=1), cardiogenic dysphagia (n=1), slight narrowing without obstruction of EGJ (n=1)-and two patients (12.5%) with chronic atrophic gastritis (n=2) were confirmed. Conclusion Esophageal motility disorders were identified in 68.8% of 16 patients with large esophageal residual barium with three patients in the major and eight patients in the minor categories. Residual barium in the esophagus was not rare and can be a sign of significant esophageal motility disorders.
