Conventional sigmoidoscopy and rectal biopsy are very useful in the diagnosis, differential diagnosis, and management of inflammatory bowel disease. The rectal biopsy is particularly important in establishing the diagnosis of Crohn's disease when the rectal mucosa is grossly normal. The sigmoidoscopy and biopsy serve to assess the response to medical therapy in inflammatory bowel disease and are important adjuncts to colonoscopy in surveillance for dysplasia and carcinoma in patients with ulcerative colitis. Sigmoidoscopy is quick, requires no preparation, is cost effective, and the biopsies are extremely safe with the use of the cupped bronchoscopic forceps.
传统乙状结肠镜检查和直肠活检在炎症性肠病的诊断、鉴别诊断及治疗中非常有用。当直肠黏膜大体正常时，直肠活检对克罗恩病的诊断尤为重要。乙状结肠镜检查和活检有助于评估炎症性肠病的药物治疗反应，并且在监测溃疡性结肠炎患者的发育异常和癌变方面是结肠镜检查的重要辅助手段。乙状结肠镜检查操作迅速，无需准备，成本效益高，并且使用杯状支气管镜钳进行活检极其安全。
