Colors play a major role in the endoscopic diagnosis of many gastrointestinal conditions. Gastrointestinal endoscopists in the Netherlands are predominantly male (> 90%), and from population data it is to be expected that approximately 8% will have a color vision deficiency. The present study was designed to assess the prevalence of color vision deficiencies amongst Dutch gastrointestinal endoscopists and to determine whether color vision deficiency affects an endoscopist's diagnostic skill. One hundred and thirty-nine gastroenterologists and physicians of internal medicine took an F2 color vision test and assessed nine videofragments of endoscopies. Color vision deficiencies were detected in 8% of Dutch gastrointestinal endoscopists. In one out of the nine video excerpts of endoscopies, a statistically significant difference was detected between test subjects with and without a color vision deficiency. However, this video excerpt showed a green pea, which could not be mistaken for a polyp at polypectomy. The study therefore does not show any effect of color vision deficiencies on endoscopic skills, nor does it show any deviant prevalence of color vision deficiencies amongst Dutch gastrointestinal endoscopists.
颜色在许多胃肠道疾病的内镜诊断中起着重要作用。荷兰的胃肠道内镜医师主要为男性（>90%），根据人口数据预计约8%的人会有颜色视觉缺陷。本研究旨在评估荷兰胃肠道内镜医师中颜色视觉缺陷的患病率，并确定颜色视觉缺陷是否会影响内镜医师的诊断技能。139名胃肠病学家和内科医生进行了F2颜色视觉测试，并评估了9段内镜视频片段。在8%的荷兰胃肠道内镜医师中检测到颜色视觉缺陷。在内镜检查的9个视频片段中的一个中，检测到有和没有颜色视觉缺陷的测试对象之间存在统计学上的显著差异。然而，这个视频片段显示的是一颗青豆，在息肉切除术中不可能被误认为是息肉。因此，该研究没有显示颜色视觉缺陷对内镜技能有任何影响，也没有显示荷兰胃肠道内镜医师中颜色视觉缺陷的患病率有任何异常。
