Colonoscopy is unsuccessful in some patients because of a fixed sigmoid loop or anatomical stenoses. We prospectively evaluated 1600 patients undergoing colonoscopy at Virginia Mason Medical Center from December 1, 1986 to November 31, 1987. Thirty-one procedures (1.9%) failed to reach the splenic flexure because of functional or anatomic stenoses. Attempt at pancolonoscopy with a 9.8-mm diameter, 102-cm length endoscope (Olympus XQ) was successful to the right colon in 73% and cecum in 60% of these patients. Two thirds of the successfully intubated patients had clarification of radiographic abnormalities or delineation of additional colon pathology. There were no complications or instrument damages, but limitations included short scope length and small suction channel. We conclude that small diameter upper endoscopes can be used safely and effectively for colonoscopy in a subset of patients in whom conventional colonoscopy is unsuccessful.
由于存在固定的乙状结肠袢或解剖学狭窄，结肠镜检查在一些患者中无法成功完成。我们前瞻性地评估了1986年12月1日至1987年11月31日在弗吉尼亚梅森医疗中心接受结肠镜检查的1600例患者。由于功能性或解剖学狭窄，31例（1.9%）操作未能到达脾曲。使用直径9.8毫米、长度102厘米的内镜（奥林巴斯XQ）进行全结肠镜检查的尝试在这些患者中，73%成功到达右半结肠，60%成功到达盲肠。三分之二成功插管的患者对影像学异常得到了明确诊断或发现了更多的结肠病变。没有并发症或器械损坏，但局限性包括镜身长度较短和吸引通道较小。我们得出结论，对于常规结肠镜检查不成功的一部分患者，小直径上消化道内镜可安全有效地用于结肠镜检查。
