Colonoscopy protection against proximal cancer can be achieved, but the level of protection has thus far been less than left colon protection. Improved proximal protection begins with effective right colon bowel preparation, best achieved by split dosing the preparation regimen. Cecal intubation in screening examinations should exceed 95%, and must be documented by photography. Examiners must be proficient in detection of subtle right colon lesions, including serrated lesions as well as flat and depressed adenomas. Effective examination should be demonstrated by meeting recommended targets for adenoma detection.
结肠镜检查可以预防近端结肠癌，但迄今为止，其预防效果不如左半结肠。提高近端结肠癌的预防效果，首先要做好有效的右半结肠肠道准备，最好采用分次剂量服用肠道清洁剂的方案。筛查性结肠镜检查时，盲肠插管率应超过 95%，且必须通过拍照记录。检查者必须熟练掌握检测细微的右半结肠病变的能力，包括锯齿状病变以及平坦和凹陷性腺瘤。通过达到腺瘤检出率的推荐目标，来证明检查是有效的。
