Introduction. Endoscopy of the colon and rectum is increasingly used. Aim of the Study. All consecutive endoscopies of the colon and rectum were studied in order to assess the yearly prevalence of significant endoscopic diagnoses. Methods. All consecutive endoscopies of the colon and rectum were included. Endoscopies were done with endoscopes of Olympus. Significant endoscopic diagnoses were defined as colorectal cancer, polyps, diverticuli, large sessile polyps, and inflammatory bowel disease. Results. In 20 years a total of 24431 endoscopies were done. The yearly number of sigmoidoscopies was mean 96, range of 42-370. The number of colonoscopies was mean 1126, range of 643-1912. The number of colonoscopies significantly increased. The number of colonoscopies on request of an internist or gastroenterologist showed a slow but steady increase. Successful caecal intubation rose from 70% to 92% in 2011. Since 1996 there is a steep increase in the percentage of procedures with abnormalities. The number of cancer and polyps increased in twenty years. No great changes were seen in inflammatory bowel disease. Conclusion. Colonoscopy is a procedure with a high diagnostic yield. The number of patients with tumours rose in twenty years.
引言。结肠和直肠内镜检查的应用越来越广泛。研究目的。对所有连续进行的结肠和直肠内镜检查进行研究，以评估重大内镜诊断的年患病率。方法。纳入所有连续进行的结肠和直肠内镜检查。内镜检查使用奥林巴斯内镜。重大内镜诊断定义为结直肠癌、息肉、憩室、广基大息肉和炎症性肠病。结果。20年间共进行了24431次内镜检查。乙状结肠镜检查的年平均次数为96次，范围为42 - 370次。结肠镜检查的次数平均为1126次，范围为643 - 1912次。结肠镜检查的次数显著增加。应内科医生或胃肠病学家要求进行的结肠镜检查次数呈缓慢但稳定的增长。2011年盲肠插管成功率从70%提高到了92%。自1996年以来，有异常操作的百分比急剧上升。癌症和息肉的数量在20年中有所增加。炎症性肠病未见重大变化。结论。结肠镜检查是一种诊断率很高的检查方法。20年间肿瘤患者数量有所增加。
