Sigmoidoscopy is an easy procedure and should be utilized more frequently. Barium enema examination is incomplete without sigmoidoscopy. Flexible fiberoptic sigmoidoscopy may have a role in the detection of disease of the descending, sigmoid, and rectosigmoid colon. The necessity for its routine usage remains to be determined. The control of colonic polyps by colonoscopy has been the greatest contribution to date by the fiberoptic instrument. Colonoscopy has improved the accuracy of diagnosis of colonic disease and, in certain instances, is helpful in the early detection of cancer of the colon. Colonoscopy complements the use of barium enema examination. Colonoscopy only for the purpose of confirmation of clinical or radiological diagnosis is often unnecessary. While the benefits of endoscopy are obvious, there are definite practical and technological limitations to its use. Complications, although infrequent, are major. Indications for colonoscopy must be clear and findings interpreted with knowledge of the limitations.
乙状结肠镜检查是一种简单的操作，应更频繁地使用。没有乙状结肠镜检查，钡剂灌肠检查是不完整的。可弯曲纤维乙状结肠镜在检测降结肠、乙状结肠和直肠乙状结肠疾病方面可能有作用。其常规使用的必要性仍有待确定。结肠镜检查对结肠息肉的控制是纤维光学仪器迄今为止最大的贡献。结肠镜检查提高了结肠疾病诊断的准确性，在某些情况下，有助于早期发现结肠癌。结肠镜检查补充了钡剂灌肠检查的应用。仅为确认临床或放射学诊断而进行的结肠镜检查往往没有必要。虽然内镜检查的益处显而易见，但其使用存在一定的实际和技术限制。并发症虽然不常见，但很严重。结肠镜检查的适应证必须明确，并且在了解其局限性的情况下解释检查结果。
