直肠结肠炎的直肠乙状结肠粘膜的外观是如此多样，以至于很难建立普遍适用和精确定义的描述术语。由于这些表现用于诊断和作为疾病过程的指示，因此重要的是，应将总体视觉印象分析为各个组成部分，并应了解描述它们时的总体变化。我们已经做了这样的分析，并测量了描述每个组件的跨变量。正如预期的那样，我们发现分级特征（例如红色色调）的观察者变化很高，而对于少数不连续变量（例如内腔中有无血液），观察者变化很低。使用这些标准中最好的，它可能会描述粘膜外观在一个更一致的方式。该研究已被限制在乙状结肠镜下看到的粘膜外观和不带望远镜。没有人试图将这些表现与直肠结肠炎的临床病程或所检查的nmxosa的组织学表现联系起来。没有人声称所定义的特征必然与疾病的严重程度有任何关系。我们分析了三个观察者在同一时间和相同条件下记录的观测结果，但我们还没有设计出一种方法来研究一个观察者在不同时间记录的一致性。
The appearances of the recto-sigmoid mucosa in proctocolitis are so diverse that it is difficult to establish generally applicable and precisely defined descriptive terms. As these appearances are used in diagnosis and as an indication of the course of the disease, it is important that the overall visual impression should be analysed into its various components and that the observer-variation in describing them should be known. We have made such an analysis and measured the observer-variation in describing each component. As might be expected, we have found that observer-variation for graded characteristics-for example, shades of red-is high and that for the few discontinuous variables-for example, the presence or absence of blood in the lumen-it is low. Using the best of these criteria, it may be possible to describe mucosal appearances in a more consistent way.The study has been limited to the mucosal appearances seen at sigmoidoscopy with and without a telescope. No attempt has been made to correlate these appearances with either the clinical course of proctocolitis or with the histological appear-ances of the nmxosa inspected. No claim is made thatthe characteristics defined necessarily have any relation to the severity of the disease. We have analysed observations recorded by three observers at one time and under the same conditions; but we have not devised a method of investigating the consistency with which one observer records at different
