小剂量番泻叶浸液在胶囊内镜肠道准备中的效果观察

The Effects Observed of Small Doses of Senna Immersion in the Capsule Endoscopy Bowel Preparation

目的观察不同方法对胶囊内镜检查前肠道准备的清洁效果。方法将40例患者按肠道清洁方法随机平分为硫酸镁组（检查前1d下午4点将50%硫酸镁25g溶于清水少许中饮完,其后半小时内饮水500mL,当日早晨5点50%硫酸镁50g溶于清水少许中饮完,其后半小时内饮水1000mL以上）及番泻叶-硫酸镁组（检查前2d进食少渣饮食,每日番泻叶2~3g用开水300mL浸泡15min后当茶饮用,检查前12h停服番泻叶,按照前组办法服用硫酸镁）。结果硫酸镁组及番泻叶-硫酸镁组患者均能耐受肠道准备。肠道清洁评分显示硫酸镁组患者优良率为65%,番泻叶-硫酸镁组优良率为90%,两组差异有显著性（P〈0.05）。结论采用小剂量番泻叶浸液加硫酸镁口服进行肠道准备可有效提高胶囊内镜的图像清晰度及病变检出率,值得临床推广。

Objective To observe the different methods of cleaning effect of bowel preparation before capsule endoscopy. Methods Divided into 40 patients with bowel cleansing method random level magnesium sulfate group （at 4 p.m. of the day before capsule endoscopy drinking 50% magnesium sulfate 25g soluble in water a little firstly, then drinking 500 mL of water within half an hour later, the next day at 5 a.m drinking 50% magnesium sulfate 50g soluble in water a little firstly, then drinking more than 1000 mL of water within half an hour later） and senna-magnesium sulfate group （eating less residue diet two days ago before capsule endoscopy, senna daily 2-3g soaked with water 300 mL after 15 minutes, then drinking the senna immersion replace tea until 12h before check, then like the former group taking the magnesium sulfate）. Results Magnesium sulfate group and senna-magnesium group patients all could tolerate the bowel preparation, bowel cleansing excellent rate the magnesium sulfate group of patients was 70%, senna-magnesiu sulfate group was 90%. Conelusion The small dose of serma immersion plus magnesium sulfate oral as bowel preparation method in capsule endoscopy can effectively, improve the images clarity and lesion detection rate, worth in clinical popularize.
