: Adequate bowel preparation is essential for high-quality colonoscopy. The clarity of the final rectal effluent can predict its sufficiency and guide additional preparation if necessary. For an objective and reliable clarity assessment, the stool collection method may be as important as the evaluation itself. This study was designed to compare the sensitivity of clarity assessments of effluent collected using two methods: a disposable cardboard bedpan with a white bag (Group I) and a 50 mL transparent plastic container (Group II). : A prospective, single-center, randomized, comparative study was conducted between August 2024 and January 2025. Based on predefined criteria, 37 of 177 randomized patients were excluded, and 140 were analyzed. : Inadequate bowel preparation was correctly identified by a team member in 71% of Group I and 23% of Group II ( = 0.033). In adequate cases, the detection sensitivity was 88% and 85% (Groups I and II, respectively; = 0.854). Significantly more patients in Group II either withdrew or failed to submit a photograph of the final rectal effluent. Patients' verbal assessments did not differ significantly between the groups, regardless of bowel preparation quality. : Patient self-assessment was an unreliable indicator of bowel cleanliness, highlighting the need for objective, standardized pre-colonoscopy evaluation methods. The use of a disposable cardboard bedpan with a white bag to collect the final rectal effluent may improve the accuracy of predicting inadequate preparation and patient compliance and may allow timely adjustments to bowel cleansing prior to colonoscopy in routine endoscopy practice.
充分的肠道准备对于高质量的结肠镜检查至关重要。最终直肠排出物的清晰度可以预测其充分性，并在必要时指导进一步的准备工作。对于客观可靠的清晰度评估，粪便收集方法可能与评估本身同样重要。本研究旨在比较使用两种方法收集的排出物清晰度评估的敏感性：带有白色袋子的一次性硬纸板便盆（第一组）和50毫升透明塑料容器（第二组）。：2024年8月至2025年1月进行了一项前瞻性、单中心、随机、对照研究。根据预定义标准，177名随机分组患者中有37名被排除，140名患者被纳入分析。：第一组中71%的患者和第二组中23%的患者被团队成员正确识别为肠道准备不充分（P = 0.033）。在准备充分的病例中，检测敏感性分别为88%和85%（第一组和第二组；P = 0.854）。第二组中撤回或未提交最终直肠排出物照片的患者明显更多。无论肠道准备质量如何，两组患者的口头评估没有显著差异。：患者自我评估是肠道清洁度的不可靠指标，这突出了需要客观、标准化的结肠镜检查前评估方法。使用带有白色袋子的一次性硬纸板便盆收集最终直肠排出物可能会提高预测准备不充分的准确性和患者依从性，并可能在常规内镜检查实践中允许在结肠镜检查前及时调整肠道清洁情况。
