[Significance of diagnostic procedures in reflux esophagitis (author's transl)].

The diagnosis of reflux esophagitis can be confirmed by a variety of diagnostic procedures. Beside the morphologic findings of the reflux demonstrated by X-ray, endoscopy, and histology, the degree of disturbed cardial function can be determined by manometry, pH determination, and scintiscan. Each method entails a number of errors. Therefore a distinction must be made between absolutely necessary and valuable methods for clarifying the degree of the symptoms of esophageal reflux.
