Gastro-oesophageal reflux and hiatal hernia. A re-evaluation of current data and dogma

Various methods of investigating and treating patients with gastro-oesophageal disorders are described and the rationale of current concepts is outlined. Emphasis is placed throughout on gastro-oesophageal reflux and its sequelae rather than on sliding hiatal hernias. Symptoms of gastro-oesophageal dysfunction can be misleading, and careful studies are essential in assessing its importance and the results of various modes of therapy.
