Esophageal Manometry and Ambulatory 24-Hour pH Monitoring in Patients With Short and Long Segment Barrett's Esophagus

Abstract

As a group, SSBE patients have more competent LES sphincters and less gastroesophageal reflux at 0 and 5 cm above the LES as compared with patients with LSBE. These data indicate that the degree and length of acid exposure in the esophagus are important factors in the pathogenesis of SIM involvement of the esophagus.
