Nasal polyposis is a chronic inflammatory process of the nasal mucosa, characterized by multiple and bilateral nasal polyps. Different drugs have been used in its treatment. In order to study the results of different treatment modalities it is necessary to have some kind of staging.
to present a new endoscopic staging method, based on nasal endoscopy and on the three-dimensional nasal polyp assessment; and compare its reproducibility with that from two other systems already established in the literature.
Cohort study.
Three experts assessed the exams of 20 patients with nasal polyposis at different times, before, at 15 and at 30 days after the start of oral prednisone, 1 mg/kg/day, during 7 days. We assessed the agreement rate among the experts, using Kappa for statistic analysis.
The three methods were reproducible, and the method hereby proposed had the least agreement among the examiners.
the three-dimensional staging system proposed proved reproducible, despite showing less agreement among the examiners than the other as the other two methods.
提出一种新的基于鼻内镜和三维鼻息肉评估的内镜分期方法，并将其与文献中已建立的两种分期方法的可重复性进行比较。
对 20 例鼻息肉患者的检查进行了队列研究。在开始口服泼尼松龙（1mg/kg/d）7 天后，分别于治疗前、治疗后 15 天和 30 天对患者进行评估。我们使用 Kappa 统计分析评估专家之间的一致性率。
三种方法均具有可重复性，且本研究提出的方法在评估者之间的一致性最低。
尽管与其他两种方法相比，所提出的三维分期系统在评估者之间的一致性较低，但该系统具有可重复性。
