Comparative StudyComparison of the main oesophageal pathophysiological characteristics between short- and long-segment Barrett's oesophagus.
To assess the oesophageal manometric characteristics and 24-h pH profiles of patients with both short-segment and long-segment Barrett's oesophagus and compare them with those of patients with reflux oesophagitis and controls. ⋯ Long-segment Barrett's oesophagus is characterized by a greater impairment of peristaltic wave amplitude and a higher oesophageal acid exposure than is short-segment Barrett's oesophagus. However, both forms are linked to increased acid reflux.
