[Value of 24-hour long-term pH monitoring with computer-assisted evaluation in gastroesophageal reflux disease].

: There are a variety of diagnostic procedures in use to confirm the diagnosis gastroesophageal reflux (reflux-esophagitis, GER). The accuracy of the described methods are different. Computerized 24 hours long term pH monitoring has established to be a very reliable procedure in the diagnosis of GER. From 1984 to 1986 134 patients underwent 24 hours pH monitoring besides X-ray, scintiscan, and esophageal-manometry. The combination of manometry and 24 hours pH monitoring has given the biggest insight into the pathogenesis of GER and seems to be undispensable for specific therapeutic procedures.
