Changes in the esophagogastric junction outflow obstruction manometric feature based on the Chicago Classification updates

Figure 3 Comparisons of parameters according to symptoms in 51 patients with elevated integrated relaxation pressure. A: Patients with dysphagia showed lower postdeglutitive upper esophageal sphincter contractile integral than patients without dysphagia; B: Patients with dysphagia showed lower proximal esophageal contractile integral than patients without dysphagia; C: Patients with dysphagia showed lower proximal esophageal length (PEL) than patients without dysphagia; D: Patients with retrosternal pain showed higher PEL than patients without retrosternal pain. PD-UESCI: Postdeglutitive upper esophageal sphincter contractile integral; PECI: Proximal esophageal contractile integral; PEL: Proximal esophageal length.
