title: Food-stimulated gastroesophageal sphincter pressure in patients with abnormal duodenal loop compared with controls.
abstract: The gastroesophageal sphincter pressure (GESP) was studied before, during, and after food intake in nine patients with abnormal duodenal loop (AD), six patients with a normal duodenum (controls), and seven healthy volunteers. In normal and control subjects a significant increase in GESP was observed during food intake, in contrast to a significant decrease in patients with AD. This may explain why patients with AD often develop symptoms when eating.
