The squamous-columnar junction or Z line macroscopically corresponds to an obvious, regular or irregular, circumferential colour change at the distal esophagus, which results from esofago de barret border between the flat esophageal mucosa and the columnar gastric mucosa.

Journal of Clinical Pathology. The 5-year results of a randomized, multicenter trial —the LOTUS trial— show that proton pump inhibitors are superior to surgery in the treatment of patients with reflux.
