Esophageal manometry findings and degree of acid exposure in short and long Barrett's esophagus.

Context: Barrett's esophagus (BE) is characterized by intestinal metaplasia in the distal esophagus and is classified as short-segment (<3 cm - SSBE) or long-segment (>3 cm - LSSBE). It is suggested that LSSBE is associated with more severe esophageal motor abnormalities and increased acid exposure time than SSBE.

Objective: To evaluate the prevalence of esophageal manometriy abnormalities and acid exposure times in patients with SSBE and LSSBE.
