    Introduction and aim: Transnasal endoscopy (TNE) has proven its diagnostic utility, but it has not been widely accepted given that it is performed without sedation. There are no previous studies on the use of methods to improve its tolerability. Our aim was to evaluate the tolerability of TNE, when simultaneously performed with an audiovisual device as a distractor. Methods: We evaluated 50 patients, 10 of whom did not agree to participate. The performance of the procedure was explained, using an audiovisual device. Before randomization, we applied anxiety and depression scores. Patients were divided into 2 groups: Group I (using an audiovisual device during the procedure) and Group II (without a device). Anxiety and numeric pain rating scales were used, and vital signs were monitored and recorded before, during, and after the endoscopy. An overall procedure satisfaction score was applied at the end of the study and 24鈥痟 later. Results: Mean age was 41.6 years and 35 of the patients were women (87.5%). The most frequent indication for TNE was refractory gastroesophageal reflux disease. There were no severe comorbidities, and none of the patients had a significant anxiety or depression score. One patient in Group II did not tolerate TNE due to nasal pain. There was no statistically significant difference between groups, regarding anxiety, pain, vital signs, and satisfaction scale. Conclusion: Our study showed that TNE was well tolerated and had a high acceptance rate in our patients. The use of distracting audiovisual devices did not increase tolerance to the endoscopic procedure. Resumen: Introducci贸n y objetivo: La endoscop铆a transnasal (ETN) ha probado su utilidad diagn贸stica; sin embargo, no se ha aceptado de manera generalizada debido a que se realiza sin sedaci贸n y no se han realizado estudios que reporten el uso de m茅todos que mejoren su tolerabilidad. El objetivo fue evaluar la tolerabilidad de la ETN cuando se realiza de manera simult谩nea con un dispositivo audiovisual como distractor. M茅todos: Se evaluaron 50 pacientes, 10 de ellos rechazaron participar. El procedimiento se explic贸 utilizando un dispositivo audiovisual. Antes de la aleatorizaci贸n, se aplicaron escalas de ansiedad y depresi贸n. Los pacientes se dividieron en 2 grupos: Grupo I (utilizando un dispositivo audiovisual durante el procedimiento) y Grupo II (sin dispositivo). Se utilizaron escalas num茅ricas de ansiedad y dolor. Se monitorearon signos vitales antes, durante y despu茅s de la endoscop铆a. Se aplic贸 una escala de satisfacci贸n al final del estudio y 24鈥痟oras despu茅s. Resultados: El promedio de edad fue 41.6 a帽os y 35 (87.5%) pacientes fueron de sexo femenino. La indicaci贸n m谩s frecuente para ETN fue enfermedad por reflujo gastroesof谩gico refractario. No se encontraron comorbilidades significativas y ning煤n participante contaba con puntuaci贸n de ansiedad o depresi贸n significativa. Un paciente del grupo II no toler贸 la ETN debido a dolor nasal. No se encontr贸 diferencia significativa en niveles de ansiedad y dolor, signos vitales y escala de satisfacci贸n entre grupos. Conclusiones: Nuestro estudio mostr贸 que la ETN es bien tolerada y tiene un porcentaje alto de aceptaci贸n en nuestros pacientes. El uso de dispositivos audiovisuales distractores no increment贸 la tolerancia al procedimiento endosc贸pico
