Linked color imaging (LCI) for image-enhanced endoscopy (IEE) highlights mucosal color differences. We investigated risk factors associated with mucosal redness of the duodenal bulb using LCI. Consecutive patients were retrospectively selected after their duodenal bulbs were observed via LCI. A symptom questionnaire (Izumo scale) was completed. The LCI of the duodenal bulb was subjectively evaluated on whether redness was present and objectively evaluated based on color values. The clinical characteristics of the 302 study participants were: male/female, 120/182; mean age, 70.9 years. Twenty-one cases (7.0%) were in the redness (+) group. After multiple regression analysis, independent predictors for the red component () of the duodenal bulb using LCI were: age (β = -0.154, < 0.01), female (β = -0.129, < 0.05), body mass index (BMI; β = -0.136, < 0.05), eradication (β = 0.137, < 0.05), endoscopic gastric mucosal atrophy score (EGAS; β = -0.149, < 0.05), and constipation-related quality of life (QOL) (β = -0.122, < 0.05) scores. Lower age, lower BMI, lower EGAS, a constipation-related QOL score, post- eradication, and being male were associated with mucosal redness in the duodenal bulb with IEE using LCI.
用于图像增强内镜检查（IEE）的联动成像（LCI）突出了黏膜颜色差异。我们使用LCI研究了与十二指肠球部黏膜发红相关的危险因素。在通过LCI观察十二指肠球部后，对连续的患者进行回顾性选择。完成了一份症状问卷（出云量表）。对十二指肠球部的LCI进行主观评估，判断是否存在发红，并根据颜色值进行客观评估。302名研究参与者的临床特征为：男/女，120/182；平均年龄70.9岁。21例（7.0%）属于发红（+）组。经过多元回归分析，使用LCI时十二指肠球部红色分量（）的独立预测因素为：年龄（β = -0.154，<0.01）、女性（β = -0.129，<0.05）、体重指数（BMI；β = -0.136，<0.05）、根除（β = 0.137，<0.05）、内镜下胃黏膜萎缩评分（EGAS；β = -0.149，<0.05）以及便秘相关生活质量（QOL）评分（β = -0.122，<0.05）。年龄较低、BMI较低、EGAS较低、便秘相关QOL评分、根除后以及男性与使用LCI的IEE检查中十二指肠球部黏膜发红有关。
