摘要
目的了解肠道准备对胶囊内镜检查的影响。方法将进行胶囊内镜检查的56例受检者随机分为肠道准备组和对照组，各28例。肠道准备组服用硫酸镁法（50％MgSO4 70ml）进行肠道准备并服用二甲基硅油2ml。对胶囊内镜图像的气泡量、肠液量及清洁度、观察效果进行定量分析，并统计胶囊内镜通过情况。结果肠道准备组和对照组的胃内气泡、胃液量、清洁度和观察效果均无统计学差异（P〉0.05）。肠道准备后，小肠内气泡的形成与小肠观察效果均有明显的改善（P〈0.05），但对肠液量和清洁度无明显的影响（P〉0．05）。两组间在胃通过时间、小肠通过时间、回盲瓣通过率上均无统计学差异（P〉0．05）。结论肠道准备有助于提高胶囊内镜图像的清晰度，从而提高观察效果；对胶囊内镜通过情况无明显影响。
Objective To evaluate the effect of bowel preparation on the transit time and image quality of capsule endoscopy . Methods Fifty-six patients who underwent capsule endoscopy were divided into two groups ： bowel preparation group （ n = 28 ） treated with oral bitter salt 4 h prior to capsule endoscopy; control group （n = 28） without bowel preparation. The image quality of endoscopy was graded according to air bubble size, digestive tract juice quantity and its clear degree. Results There was no difference about all measuring index in stomach between two groups. The bowel preparation group presented significantly better quality of images compared to the control group （ P 〈 0. 05 ）. The gastric emptying time and the small bowel transit time were unaffected. Conclusion Bowel preparation bad ability to improve the quality of capsule endoscopy images. Bowel preparation is a sound modality before capsule endoscopy.
