To show the reliabilities of the new mixture (composed of water, methylcellulose, lactulose, locust bean gum, and sorbitol) and to compare the luminal distension and radiological confidence scores of this solution with water-lactulose mixture.
Computed tomography enterography (CTE) images in a three-year period were included randomly in our institutional review board-approved and retrospective study. Ninety-one patients drank a lactulose and water mixture (Group 1), and 54 patients drank the new mixture (Group 2). Patients who drank the oral contrast agent were taken to a 64-detector row multiple detector computed tomography machine. Coronal and sagittal reformatted images were also formed. The gastrointestinal tract was divided into 11 segments for scoring. Each segment was graded for distensional and radiological confidence. CTE images were evaluated by two radiologists.
Inter- and intra-reader reliabilities were good or excellent for all gastrointestinal segments in both groups ( < 0.001). The best κ values were obtained in sigmoid colon assessments. Lower agreement values were detected in duodenum and jejunum scores. The new mixture group (Group 2) showed better results than Group 1 for ileum and colonic segments according to distension and confidence scorings.
Inter- and intra-reader reliabilities of the new mixture were good or excellent for CTE. The new mixture seems to be more efficient and reliable for ileum and colon. The new mixture can increase bowel distention, radiological confidence, and quality in CTE evaluations.
展示新混合物（由水、甲基纤维素、乳果糖、刺槐豆胶和山梨醇组成）的可靠性，并将该溶液与水 - 乳果糖混合物的肠腔扩张和放射学置信度评分进行比较。
在我们机构审查委员会批准的回顾性研究中，随机纳入了三年期间的计算机断层扫描小肠造影（CTE）图像。91例患者饮用乳果糖和水的混合物（第1组），54例患者饮用新混合物（第2组）。饮用口服造影剂的患者被带到一台64排多层螺旋CT机处。还形成了冠状面和矢状面的重组图像。胃肠道被分为11个节段进行评分。每个节段根据扩张情况和放射学置信度进行分级。CTE图像由两名放射科医生进行评估。
两组所有胃肠道节段的阅片者间和阅片者内可靠性均为良好或优秀（<0.001）。在乙状结肠评估中获得了最佳的κ值。在十二指肠和空肠评分中检测到较低的一致性值。根据扩张和置信度评分，新混合物组（第2组）在回肠和结肠节段的表现优于第1组。
新混合物在CTE中的阅片者间和阅片者内可靠性良好或优秀。新混合物似乎对回肠和结肠更有效且可靠。新混合物可以提高CTE评估中的肠管扩张程度、放射学置信度和质量。
