目的探讨胶囊内镜对小肠疾病的诊断价值及安全性。方法选择2014年1月至2015年12月经影像学、实验室检查疑诊小肠疾病78例老年患者。收集临床资料、胶囊内镜检查结果,并进行随访。对小肠核磁造影与胶囊内镜病变检出率进行ROC曲线分析。结果小肠MRI造影诊断曲线下面积(AUC)为0.571,胶囊内镜诊断AUC为0.785,差异有统计学意义(P<0.05);两者结合诊断AUC为0.937。随访过程中,患者发生胶囊滞留3例,胶囊滞留率为3.85%,只有1例(1.28%)患者发生肠梗阻。结论使用胶囊内镜对小肠疾病的病因诊断明显高于小肠核磁造影,使用胶囊内镜联合小肠核磁造影可有效提高诊断率。胶囊内镜相对较为安全,患者耐受好,并发症发生率低。
Objective To investigate the diagnostic value and safety of capsule endoscopy on small intestinal diseases. Methods From January 2014 to December 2015, 78 elderly patients with suspected small bowel disease were examined by imaging and laboratory tests. Collect clinical data, capsule endoscopy results and follow-up. ROC curve analysis of the detection rate of small intestine nuclear magnetic resonance and capsule endoscopy lesions. Results The area under the curve of small bowel MRI (AUC) was 0.571, and the AUC of capsule endoscopy was 0.785, the difference was statistically significant (P <0.05). The combined diagnostic AUC was 0.937. During the follow-up, there were 3 patients with capsule retention, 3.85% capsule retention, and only 1 patient (1.28%) had intestinal obstruction. Conclusion The diagnosis of intestinal diseases by capsule endoscopy was significantly higher than that of small intestine. The use of capsule endoscopy combined with small-intestine magnetic resonance imaging could effectively improve the diagnosis rate. Capsule endoscopy is relatively safe, patient tolerance is good, the incidence of complications is low.
