    Author: Adamek RJ, Wegener M, Wienbeck M.
    Journal: Z Gastroenterol; 1993 Dec; 31(12):751-7. PubMed ID: 8310730.
    Abstract:
    The results of a cardiologic work-up in patients with retrosternal pain are negative in about 20-30% of cases. Overall one half of these patients exhibit an esophageal dysfunction. In order to diagnose esophageal dysfunction long-term pH-metry, transit scintigraphy and standard manometry are used as well as provocation tests. New diagnostic procedures such as long-term manometry and combined long-term pH-metry and manometry have recently been developed and are increasingly used. Long-term pH-metry is a valid, uncomplicated and sensitive procedure used to diagnose acid gastroesophageal reflux. The differential diagnosis of hypermotility esophageal dysfunction is, however, considerably more difficult. Scintigraphy appears unsuitable. The value of standard manometry is hindered by the short examination time and the rare possibility to correlate pain episodes and motility disorders. It is therefore recommended that a provocation test should be carried out after standard manometry. Preliminary results for long-term manometry are now available. These show that it is not only possible to correlate pain episodes and motility disorders but also to differentiate pathological manometry profile. This applies also to combined pH-metry and manometry reducing patients discomfort to one examination.
