The Position of Outpatient 24-Hour Dual-Probe pH-metry in the Diagnostics of Extraosophageal RefluxVe studii budeme zkoumat extraezofageální reflux, jedná se o podskupinu refluxní nemoci jícnu, kdy jsou v popredí mimojícnové projevy kyselého refluxu. Závery studií uzavírají, že EER v ruzné míre prispíva ke vzniku, nebo prímo zpusobuje nekteré ORL nemoci. Pokud je na EER pomýšleno, muže se použít diagnosticko-terapeutický test (pozitivní odezva na podání inhibitoru protonové pumpy) nebo pH-metrii. V rámci studie bude podáván Lanzul 30mg 2xdenne po dobu 12 týdnu.
