Ultrasonographic study of antral motility in patients with Barrett's oesophagus and erosive oesophagitis

Background: Antral contractility and antroduodenal motility are major physiologic determinants of gastric emptying (GE). Delayed GE has been demonstrated in patients with reflux disease. In our previous study, using ultrasonography, we have investigated the role of the proximal stomach in the GE of patients with erosive oesophagitis (EO) or with Barrett's oesophagus (BO). The aim of the present study was the assessment of the antral contractility and its role in GE in these two subsets of patients with reflux disease. Patients and methods: Twenty-one patients BO, 17 patients with moderate EO (10 LA-A; 7 LA-B), a…
