A high-quality bowel cleansing preparation is an essential prerequisite for a safe, efficient, and accurate colonoscopy. Large studies, however, have shown that up to 25% of patients undergoing colonoscopy have what is considered to be an inadequate preparation. A well-done survey reported in this issue of the American Journal of Gastroenterology by Ben-Horin et al. found considerable variability among endoscopists in their assessment of preparation adequacy from photographs of three representative cases. When the preparation was judged suboptimal, follow-up colonoscopy often was recommended at shorter time intervals than is currently indicated by clinical guidelines. Because this practice is not supported by any direct investigation, a better practice might be to determine if the preparation is poor or inadequate, indicating instead the need for a prompt repeat preparation and another colonoscopy.
高质量的肠道清洁准备是安全、高效且准确的结肠镜检查的必要前提。然而，大型研究表明，接受结肠镜检查的患者中，高达25%的人肠道准备被认为不充分。本-霍林等人在本期《美国胃肠病学杂志》上发表的一项完善的调查发现，内镜医师对三张代表性病例照片的准备充分程度评估存在很大差异。当准备情况被判定为欠佳时，通常建议的后续结肠镜检查时间间隔比目前临床指南所规定的更短。由于这种做法没有任何直接研究支持，更好的做法可能是确定准备是否不佳或不充分，而是表明需要迅速重复准备并再次进行结肠镜检查。
