About this study
Official title: Transnasal Endoscopic Evaluation of Swallowing: Functional Esophagoscopy Using an Ultrathin Video Endoscope in Neurogenic Dysphagia
The esophago-gastro-duodenoscopy is an endoscopic examination technique of the upper GI-tract which was founded by the German surgeon Johann Freiherr von Mikuliicz-Radecki at the end of 19th century. By this means, the luminal site of the esophagus, stomach and duodenum may be visualized after inserting a flexible endoscope through the mouth (transoral access). By the rapid technical development in the last years smaller flexible video endoscopes have been developed allowing also an alternative access to the upper GI-tract via the nose (transnasal access).
Patients with dysphagia are referred to physicians of different disciplines (gastroenterology, surgery, ear, nose, and throat (ENT) medicine, radiology, neurology) performing a variety of endoscopic and non-endoscopic techniques. Mostly, the endoscopic examination of the esophagus is done in sedated patients in left lateral examination. Typical findings during esophagoscopy might be tumors, strictures, achalasia or diverticula.

Patients suffering from neurogenic dysphagia often get caught in the trap: they find themselves somewhere in the space between gastroenterologist, neurologist, ENT-specialist and radiologist. This dilemma might be due to a lack of pathophysiological knowledge among many physicians and an inability to directly visualize the esophageal phase of deglutition. In sedated patients lying in left lateral position, endoscopists may receive a very limited impression of the function of the different phases of swallowing since this endoscopic access is a rather static one.
The focus of our observational study are patients with suspected neurogenic dysphagia. These patients shall be examined by transnasal endoscopy applying an ultrathin video endoscope with an outer diameter of 3.8 mm (BF-3C160, Olympus Europe). Patients are examined in sitting position while ingesting water and food of different consistencies (functional endoscopy). Diagnostic shall be completed and correlated by videofluoroscopy, high-resolution manometry and assessment of the clinical signs. Beside feasibility and safety as primary endpoints, secondary endpoints shall be the assessment of pathologic endoscopic findings in patients suffering from neurogenic dysphagia. The study is approved by the local Ethics Committee (AZ 2010-214-f-S).

Questions about this trial
What is this clinical trial studying?
An observational study of Neurogenic Dysphagia, run by University Hospital Muenster at 2 sites in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients in which the procedure may be successfully performed (feasibility) (time frame: 30 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01995929, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Nov 2022.
