Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="den12209-sec-0001" sec-type="section"> <title>Background and Aim</title> <p>Although transnasal endoscopy (TNE) is generally a comfortable and safe procedure, it has some disadvantages, such as complicated preprocessing and occasional repulsion reaction during catheterization. In an attempt to simplify the preprocessing method, the efficacy of a catheter‐free method in which a catheter is not inserted into the nasal cavity was assessed.</p> </sec> <sec id="den12209-sec-0002" sec-type="section"> <title>Methods</title> <p>The present study was a prospective, open‐label, single‐center, randomized controlled study with parallel assignment allocation 1:1. Between March 2009 and August 2009, a total of 93 TNE‐naïve patients were enrolled and randomized. Patients were prospectively randomized into two groups (catheter‐free <italic>vs</italic> catheter‐insertion method). Patients who prepared according to the catheter‐free method and who were unsuccessful underwent the catheter‐insertion method. Clinical characteristics, success rate, complications, vital signs, acceptability, and tolerability were assessed and compared.</p> </sec> <sec id="den12209-sec-0003" sec-type="section"> <title>Results</title> <p>Success rates of the catheter‐free and catheter‐insertion methods were 88% (<italic>n</italic> = 44) and 88% (<italic>n</italic> = 38) (<italic>P</italic> > 0.05), respectively. Causes of failure in the catheter‐free method included severe rhinalgia (<italic>n</italic> = 1, 2%) and narrowing of the nasal cavity (<italic>n</italic> = 5, 10%). Causes of failure in the catheter‐insertion method included narrowing of the nasal cavity (<italic>n</italic> = 5, 11%). Six patients whose TNE failed with the catheter‐free method also experienced failed TNE with the catheter‐insertion method. There were no statistical differences in vital signs, acceptability, and tolerability.</p> </sec> <sec id="den12209-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The catheter‐free method is sufficient for preparation for TNE. The success rate of TNE depends more on the structure of the nasal cavity than the preprocessing method.</p> </sec> </abstract>
