title: Radiologic quantitation of gastro-oesophageal reflux. Correlation between height of food stimulated gastro-oesophageal reflux and level of histologic changes in reflux oesophagitis.
abstract: In a prospective study, 26 patients with symptoms of reflux oesophagitis underwent a barium examination for gastro-oesophageal reflux after food stimulation, and endoscopy with biopsy from different levels of the oesophagus. Radiologic grading of the gastro-oesophageal reflux depending on the height of the reflux into the oesophagus was performed, and this was correlated to the microscopic appearance at different levels in the oesophagus. Complete agreement between the radiologic grading and the histology was found in 69 per cent of the cases, and when gastro-oesophageal reflux was demonstrated the agreement was 75 per cent. Accordingly, the results showed a good accordance between the two variants, indicating that the height of the reflux during the food stimulated test may be truly indicative of the reflux height under non-test conditions.
