- Abstract
Assessment of oesophageal muscle wall thickness with high-frequency intraluminal ultrasound (HFIUS) is proposed as a method to evaluate longitudinal muscle contraction and oesophageal shortening in patients with oesophageal symptoms. Studies using this technique suggested that prolonged oesophageal wall thickening can be associated with chest pain and heartburn. Validation studies comparing HFIUS measurements against fluoroscopic investigations of oesophageal shortening are not available. The aim of this study was to evaluate the relationship between oesophageal muscle wall thickening and oesophageal shortening in vivo.
