Colonoscopy is an important diagnostic procedure for screening as well as for patients presenting with complaints. The completion of a colonoscopy is defined as cecal intubation. A large single center study was done in order to evaluate the completion rate of colonoscopy and identify reasons for failure.
We reviewed all consecutive endoscopies of the lower digestive tract done over a period of 15 years by 2 endoscopists. The main outcome measure was a successful cecal intubation.
14,139 consecutive colonoscopies were done. Overall cecal intubation was successful in 11,787 procedures (83.3%). Three hundred and sixty-one of the non-successful procedures were due to insufficient colon cleansing, and no significant abnormalities were seen in 362 procedures. In the remaining 1,629 endoscopies, significant diagnoses were made. The presence of colorectal cancer, diverticula and inflammatory bowel disease were significant findings in non-successful procedures.
In normal daily practice, colonoscopy is completed in 83.3% of the procedures. Reasons for failure are obstructing tumors, diverticula and insufficient colon cleansing.
结肠镜检查是筛查和有症状患者的重要诊断程序。结肠镜检查的完成定义为盲肠插管。为了评估结肠镜检查的完成率并确定失败的原因，进行了一项大型单中心研究。
我们回顾了两位内镜医生在 15 年期间进行的所有连续下消化道内镜检查。主要观察指标是盲肠插管成功。
共进行了 14139 例连续结肠镜检查，11787 例（83.3%）成功插管。361 例非成功病例归因于结肠清洁不充分，362 例无明显异常。在其余 1629 例内镜检查中，做出了重要诊断。非成功病例中发现结直肠癌、憩室和炎症性肠病等有意义的诊断。
在日常实践中，结肠镜检查完成率为 83.3%。失败的原因是阻塞性肿瘤、憩室和结肠清洁不充分。
