What is endoscopic surveillance?
Patients with Barrett’s are examined by a specialized doctor, a gastroenterologist, at regular time intervals (endoscopic surveillance) so if they get cancer it can be removed early to increase their chances of living longer. This examination usually include inserting a tube into the patient’s esophagus (endoscopy) to examine it closely, and to get pieces of tissue (biopsy) from it which are then sent to a pathology laboratory for examination.
