LESL: lower esophagus sphincter length; LESP: lower esophagus sphincter resting pressure; IRP: integrated relaxation pressure; UESP: upper esophagus sphincter resting pressure; UESRP: upper esophagus sphincter residual pressure; NEMD: nonspecific esophageal motility disorder; GERD: gastroesophageal reflux disease; EGJOO: esophagogastric junction outflow obstruction.
