Some pathologists consider it a consequence of GERD so that in the absence of symptoms carditis defines ” asymptomatic reflux “. Follow-up BE without dysplasia Patients with BE have a poorer quality of life as compared to the general population ; in addition, they do not adequately understand and usually overestimate the frequency of malignancies associated with their disease Health Technol Assess ; Location of the lower oesophageal sphincter and the squamous columnar mucosal junction in healthy controls and patients with different degrees of endoscopic oesophagitis.
