纤维大肠镜用于临床已有30余年历史,近年来随着器械的不断改进,新型内镜,尤其电子大肠镜的推出,使大肠镜的性能已臻完善。临床上插镜技术不断提高,单人操作也能完成整个检查过程。插入回盲部的成功率可高达99%,速度已缩短到10分钟左右,并能检查回肠末端,从而推动了大肠镜外科的发展,扩大了大肠疾病的诊断治疗范围。大肠镜检查与生理、生化 Fiber colonoscopy has been used clinically for more than 30 years. With the continuous improvement of instruments in recent years, the introduction of new endoscopes, especially electronic colonoscopes, has perfected the performance of colonoscopy. Clinically inserted mirror technology continues to improve, single-person operation can complete the entire inspection process. Inserting the ileocecal success rate of up to 99%, the speed has been reduced to 10 minutes, and can check the terminal ileum, thus promoting the development of colonoscopy, expanding the scope of diagnosis and treatment of colorectal disease.
