One-stop-shop Endoscopy in Reflux-patients: Evaluation of ENT and GI Features

Study Overview
=================
Brief Summary
-----------------
Patients suffering from gastroesophageal reflux may suffer from both esophageal and laryngeal irritations. The investigators developed an endoscopic technique called functional endoscopy to evaluate alterations in the larynx and pharynx as well as in the esophagus simultaneously as one-stop-shop.

Detailed Description
-----------------
Patients suffering from gastroesopheal reflux may present to a variety of medical specialists according to their individual complaints (e.g., heartburn, hoarseness, dysphasia). In general, these addressed specialist may focus their attention to their individual fields of interest. The investigators developed an endoscopic technique called functional endoscopy to evaluate patients with various GI- or ENT (ear-nose-throat)-symptoms being suggestive for gastroesophageal reflux disease. In functional endoscopy, unsedated patients are examined with an ultrathin endoscope via the transnasal route. Reflux-associated features in the field of interest of the ENT-doctor and the GI-specialist are recorded and documented in the same session.
