Transnasal endoscopy has recently become common in Japan. Although transnasal endoscopy has many advantages, nasal pain and epistaxis are common complaints. To reduce nasal pain and epistaxis, we developed a new tube sheath system for transnasal endoscopy. This new tube sheath system (outer sheath and inner tube), called the Nasal Slider, is produced by TOP Corporation, Japan.
A tube sheath longer than the nasal concha is inserted to reduce pain along the nasal turbinate. Because the sheath is left in place, tubes can be passed through the nose multiple times without causing additional pain. A total of 34 consecutive patients (mean age 68.1 years; 22 men and 12 females) who had undergone transnasal endoscopy in the past were selected for transnasal endoscopy with the Nasal Slider. After the transnasal endoscopy was completed, patients who gave consent for use of the Nasal Slider were interviewed by using 3 questionnaires on nasal discomfort, nasal pain, and epistaxis.
Because the transnasal endoscope passes inside the sheath, epistaxis can be prevented. Thirty of 34 selected patients underwent transnasal endoscopy using the Nasal Slider. Twenty-seven and 28 patients reported feeling less nasal discomfort and pain, respectively, with the Nasal Slider than during examinations without the Nasal Slider. No epistaxis developed in any patient examined with the Nasal Slider.
The Nasal Slider appears to reduce nasal pain and epistaxis during transnasal endoscopy and is currently used in many hospitals in Japan.
经鼻内镜检查在日本已较为普及。虽然经鼻内镜检查有许多优点，但鼻痛和鼻出血是常见的并发症。为了减少鼻痛和鼻出血，我们开发了一种新的经鼻内镜管鞘系统。这种新的管鞘系统（外鞘和内管），称为鼻腔滑管器，由日本 TOP 公司生产。
插入比鼻甲长的管鞘以减轻沿鼻甲的疼痛。由于鞘管保留在原位，因此可以多次通过鼻腔而不会引起额外的疼痛。我们共选择了 34 例连续接受经鼻内镜检查的患者（平均年龄 68.1 岁；22 名男性，12 名女性），使用鼻腔滑管器进行经鼻内镜检查。经鼻内镜检查完成后，对同意使用鼻腔滑管器的患者进行了 3 项问卷调查，以了解其鼻腔不适、鼻痛和鼻出血情况。
由于经鼻内镜在内鞘内通过，因此可以预防鼻出血。在 34 例选定的患者中，有 30 例使用鼻腔滑管器进行了经鼻内镜检查。有 27 例和 28 例患者分别报告使用鼻腔滑管器时鼻腔不适和疼痛减轻。使用鼻腔滑管器检查的患者均未发生鼻出血。
鼻腔滑管器似乎可以减少经鼻内镜检查时的鼻痛和鼻出血，目前在日本许多医院使用。
