目的研究胶囊内镜对消化道疾病的诊断价值。方法检查前2d,要求患者进食无渣食物,检查前1d中午和晚上,患者分别取20g番泻叶用开水泡茶服2～3杯,晚上要求患者进食全流食物或禁食,检查当日晨禁食,用20%甘露醇250ml,5%糖盐水1000ml及纯净水1000～1500ml口服,在1～1.5h内服完。吞服胶囊前30min可服用10%的二甲基硅油(消泡剂)50ml,30min后干咽或者用100ml清水吞服胶囊;然后,在实时监控下,观察食道和胃的病变情况;胶囊进入十二指肠后患者可携带图像记录仪离开医院。结果112例中发现有消化道病变者105例(1例患者可发生多种疾病),阳性检出率占93.7%。其中食道炎13例,食道息肉2例,糜烂性胃炎35例,胃溃疡17例,胃息肉12例,胆汁反流24例,十二指肠溃疡9例,小肠息肉5例,小肠血管异常11例,小肠炎19例,克罗恩病5例,肠道钩虫2例,结肠息肉18例,结肠癌1例,结肠粘膜黑变病6例。结论胶囊内镜图像清晰,操作简便,无副反应,胶囊内镜对消化道疾病具有较好的诊断效果,特别适用于小肠疾病和不明原因消化道出血患者的诊断。
Objective To study the diagnostic value of capsule endoscopy on gastrointestinal diseases. Method 2d before examination, requiring patients to eat non-residue food, 1d at noon and night before the test, patients were taken 20g senna with 2 or 3 cups of boiling water tea, night requiring patients to eat whole-flowed food or fasting, check the morning Fasting, with 20% mannitol 250ml, 5% sugar water 1000ml and purified water 1000 ~ 1500ml orally, within 1 ~ 1.5h oral finished. Thirty minutes before swallowing the capsule, take 10ml of dimethylsilicone oil (defoaming agent) 50ml, dry swallow 30min or swallow capsules with 100ml of water; then observe the esophagus and stomach lesions under real-time monitoring; After the duodenum patients can carry the image recorder left the hospital. Results In 112 cases, there were 105 cases of digestive tract lesions (one case of multiple diseases can occur), the positive rate was 93.7%. Among them, 13 cases of esophagitis, 2 cases of esophageal polyps, 35 cases of erosive gastritis, 17 cases of gastric ulcer, 12 cases of gastric polyps, 24 cases of bile reflux, duodenal ulcer in 9 cases, 5 cases of small intestine polyps, intestinal vascular abnormalities 11 19 cases of enteritis, 5 cases of Crohn’s disease, 2 cases of intestinal hookworm, 18 cases of colon polyps, 1 case of colon cancer and 6 cases of colonic mucosal melanosis. Conclusion Capsule endoscopy images are clear, easy to operate, no side effects, capsule endoscopy has a good diagnosis of gastrointestinal diseases, especially for small intestinal diseases and patients with unknown causes of gastrointestinal bleeding diagnosis.
