Abstract
Background: Because of the malignant potential of Barrett's oesophagus , an aim of treatment is to cause the columnar epithelium to regress. A logical approach is to decrease acid reflux which is an important ae tiological factor in Barrett's oesophagus. Treatment with omeprazole 2 0-80 mg over 1-3 years has yielded conflicting but largely disappointi ng results. Aim: To determine if treatment of Barrett's oesophagus wit h omeprazole 20 mg daily for up to 6 years can cause regression of the Barrett's epithelium. Patients and Methods: Forty-seven patients with Barrett's oesophagus were treated in an open prospective study, Nine patients were treated for 2 years, 12 for 3 years, 10 for 4 years, eig ht for 5 years and eight for 6 years. Patients were endoscoped at 1-2- year intervals and endoscoped at the end of the treatment period. Resu lts: No significant shortening of the length of the Barrett's segment was seen during any treatment period, although omeprazole controlled r eflux symptoms and was well tolerated. Macroscopic squamous islands ap peared in 55% of patients, mostly in the first 2-3 years although in f ive patients they appeared later in treatment. Conclusion: Treatment o f Barrett's oesophagus with omeprazole 20 mg daily for periods of up t o 6 years did not cause regression in the length of the Barrett's segm ent, but it did lead in over half of the patients to partial re-epithe lialization in the form of squamous islands.
