OBJECTIVES: The aim of this study is to evaluate the value of Restech in patients with GERD and extraesophageal reflux symptoms.
RESULTS: A total of 26 patients were included. They all had extraesophageal symptoms such as cough (54%), hoarseness (42%), globus sensation (31%) and asthma (8%). Classical symptoms such as heart burn (58%), regurgitation (46%), odynophagia (19%) and retrosternal pain (19%) were also present. Extraesophageal symptoms without classical symptoms existed in 2 patients (18%). The 24 hours pH metry was positive in 73% (n=19, DeMeester Score 96 [16-285]) and in 27% normal (n=7, DeMeester-Score=9 [0-14]). Restech evaluation in patients with pathologic pH metry was positive in 8/19 cases (median DeMeester-Score=69 [16-285], median Ryan score=210 [35-650]). In 71% pf patients with normal pH-metry, Restech evaluation was pathologic (n=5, median DeMeester-score=12 [10-14], median Ryan score=67 [55-82]).
CONCLUSION: Restech Evaluation was positive in more than 50% of cases. Especially in patients with borderline elevated results in 24 hour pHmetry, the Restech examination helps support the decision for or against surgery. To validate this technique further studies which include post-operative data will be necessary.
