Surveillance of patients with Barrett esophagus is controversial. Practitioners should have a detailed discussion with the patient about the implications, efficacy, costs, risks, and benefits of surveillance strategies.
There is no conclusive evidence that surveillance reduces mortality from esophageal adenocarcinoma.
The American College of Gastroenterology and the European Society of Gastrointestinal Endoscopy recommend endoscopic surveillance every 3 to 5 years for nondysplastic Barrett esophagus, depending on the length of the Barrett esophagus segment. Endoscopic surveillance should be performed with high-definition white light endoscopy and using a systematic protocol for biopsies: four-quadrant biopsies at 2 cm intervals in patients without dysplasia, and 1 cm intervals in patients with previous history of dysplastic Barrett esophagus.[7]Shaheen NJ, Falk GW, Iyer PG, et al.

A second gastrointestinal expert pathologist should review the biopsies.
Should undergo a course of acid suppression therapy with proton-pump inhibitors.
Should then be re-evaluated with extensive biopsies in 3 to 6 months after optimization of acid-suppressive therapy.
If a subsequent endoscopy and biopsies at 3 to 6 months reveal no definite dysplasia, surveillance interval for nondysplastic Barrett esophagus should be followed. If repeat biopsies demonstrate indefinite for dysplasia again, a surveillance interval of 12 months is advised.
The National Institute for Health and Care Excellence (NICE) in the UK suggests considering endoscopic surveillance at an interval of 6 months with dose optimization of acid-suppressant medication.[33]National Institute for Health and Care Excellence.

Acid suppression with proton-pump inhibitors is recommended.
Endoscopic surveillance with systematic biopsies is recommended 1 year after endoscopic eradication therapy, and every 2 years thereafter.

Endoscopic surveillance should be repeated 3 months, 6 months, and 12 months after endoscopic eradication therapy, and annually thereafter.
