title: Treatment of chronic duodenal ulcer.
abstract: The cause of peptic ulcer is unknown but the authors calculate that 70 per cent of duodenal ulcers are due to environmental factors. Acid secretion appears to be an essential component: although two thirds of patients with duodenal ulcer have a normal rate of acid secretion, 90 per cent of ulcers respond to its reduction. The case against the role of acid has been argued by Cleave.
