Two adult-size endoscopes (Olympus GIF-K2 and ACMI TX-8) were compared for extent of duodenal intubation by the endoscopist's estimate of location and x-ray position in 55 patients. The endoscopes were not different in duodenal position when separately analyzed for the endoscopist's estimate or x-ray location. Combining the results for both endoscopes showed the endoscopist's estimate to differ significantly from x-ray location in 47% of patients (p = 0.02). When incorrect, the endoscopist overestimated 62% of the time and underestimated 38% of the time. X-ray evaluation of insertion depth confirmed that the second portion of the duodenum was reached in 96%, third portion in 51%, and fourth portion or beyond in 38% of patients. We conclude that fluoroscopic confirmation may be necessary when endoscopically assessing distal duodenal segments for pathology.
在55例患者中，通过内镜医师对位置的估计和X线定位，比较了两种成人尺寸的内镜（奥林巴斯GIF-K2和ACMI TX-8）十二指肠插管的程度。在内镜医师的估计或X线定位单独分析时，两种内镜在十二指肠位置上没有差异。将两种内镜的结果合并显示，在47%的患者中，内镜医师的估计与X线定位有显著差异（p = 0.02）。当估计错误时，内镜医师高估的时间占62%，低估的时间占38%。X线对插入深度的评估证实，96%的患者到达十二指肠第二部，51%到达第三部，38%到达第四部或更远部位。我们得出结论，在内镜评估十二指肠远端节段的病变时，可能需要荧光透视确认。
