Researchers report that unsedated transnasal endoscopy is a feasible, safe, and well-tolerated method to screen for esophageal disease in a primary care population.
Diagnosed early, well before patients develop swallowing problems, esophageal cancer is usually curable. A cure is most certain if the problem is detected and corrected before or during the advanced precancerous stage. But for about 90 percent of patients, early detection and treatment are missed, and the outcome is fatal.
An ultrathin endoscope inserted via a nostril, so-called transnasal esophagogastroduodenoscopy (TN-EGD) is widely accepted nowadays.
The use of sedation is also associated with an increase in cost, loss of work on the day of endoscopy and the need for the patient to be accompanied home after the procedure. Transnasal endoscopy has advantages such as no sedation and less patient monitoring, nursing time and expenses than conventional per oral EGD.
