To suggest a new cleansing score system for small bowel preparation and to evaluate its clinical efficacy.
Twenty capsule endoscopy cases were reviewed and small bowel preparation was assessed with the new scoring system. For the assessment, two visual parameters were used: proportion of visualized mucosa and degree of obscuration. Representative frames from small bowel images were serially selected and scored at 5-min intervals. Intraclass correlation coefficient (ICC) was obtained to assess the reliability of the new scoring system. For efficacy evaluation and validation, scores of our new scoring system were compared with another previously reported cleansing grading system.
Concordance with the previous system, inter-observer agreement, and intra-patient agreement were excellent with ICC values of 0.82, 0.80, and 0.76, respectively. The intra-observer agreements at four-week intervals were also excellent. The cut-off value of adequate image quality was found to be 2.25.
Our new scoring system is simple, efficient, and can be considered to be applicable in clinical practice and research.
提出一种新的小肠清洁评分系统，并评估其临床疗效。
回顾性分析 20 例胶囊内镜病例，采用新的评分系统对小肠准备情况进行评估。评估时使用两个视觉参数：可见黏膜比例和混浊程度。从小肠图像中连续选择有代表性的帧，并在 5 分钟间隔内进行评分。采用组内相关系数（ICC）评估新评分系统的可靠性。为了进行疗效评估和验证，将我们新的评分系统的评分与另一种先前报道的清洁分级系统进行比较。
与先前的系统一致，观察者间、观察者内和患者内的一致性均非常好，ICC 值分别为 0.82、0.80 和 0.76。四周间隔的观察者内一致性也非常好。发现足够图像质量的截止值为 2.25。
我们的新评分系统简单、高效，可以考虑在临床实践和研究中应用。
