title: Gastro-oesophageal sphincter pressure and reflux in controls and patients with abnormal duodenal loop.
abstract: Twenty-two patients with chronic upper dyspepsia but without ulcer disease were examined for gastro-oesophageal reflux and gastro-oesophageal sphincter pressure. Thirteen had an abnormal duodenal loop and nine a normal duodenum. An increased incidence of gastro-oesophageal reflux was found in patients with abnormal duodenal loop, whereas no differences were seen in the gastro-oesophageal sphincter pressure.
