Flexible sigmoidoscopy after age 50 has been recommended by the American Cancer Society for colorectal cancer screening. A questionnaire to assess the difficulties encountered in learning to perform this procedure was given to 19 surgical oncology fellows after a 3-month rotation in the Division of Colorectal Surgery. Sixteen (84%) trainees related that between 10-20 flexible sigmoidoscopies were necessary before they felt competent. The most difficult aspect of learning flexible sigmoidoscopy was the torquing technique followed by the ability to determine the location of the proximal bowel lumen. All 19 trainees rated the ability to recognize pathology as not difficult. In this group of surgical trainees, the mean number of flexible sigmoidoscopy performed before competency was established was 15; torquing the shaft of the sigmoidoscope was the most difficult aspect to learn. The majority of the trainees recorded that following the performance of 15-20 endoscopies, torquing became easier.
美国癌症协会建议50岁以上人群进行乙状结肠镜检查以筛查结直肠癌。在结直肠外科进行了3个月轮转培训后，向19名外科肿瘤学住院医师发放了一份问卷，以评估他们在学习该操作过程中遇到的困难。16名（84%）受训者表示，在感觉自己能够胜任之前，需要进行10至20次乙状结肠镜检查。学习乙状结肠镜检查最困难的方面是扭转技术，其次是确定近端肠腔位置的能力。所有19名受训者都认为识别病变的能力不难。在这组外科受训者中，在确定能够胜任之前，乙状结肠镜检查的平均次数为15次；扭转乙状结肠镜的镜杆是最难学习的方面。大多数受训者记录到，在进行15至20次内镜检查后，扭转操作变得更容易了。
