摘要目的 探讨双气囊小肠镜在小肠克罗恩病(CD)诊断中的价值.方法 回顾性总结141例临床怀疑小肠CD行双气囊小肠镜检查患者的临床资料,以病理诊断结合内镜表现和临床随访结果为最终诊断结果,对比分析小肠CD双气囊小肠镜、CT小肠成像以及胶囊内镜的检出率和确诊率.结果 双气囊小肠镜检出小肠CD 128例,检出率为90.8％( 128/141),最终经病理及临床随访确诊126例,确诊率为98.4％ (126/128)；CT小肠成像检出小肠CD 19例,检出率为76.0％( 19/25),最终经病理及临床随访确诊17例,确诊率为89.5％ (17/19)；胶囊内镜镜检出小肠CD 15例,检出率为60.0％( 15/25),最终经病理及临床随访确诊14例,确诊率为93.3％ (14/15).双气囊小肠镜组小肠CD检出率和确诊率均高于胶囊内镜和CT小肠成像.结论 双气囊小肠镜在小肠CD诊断中具有较好的应用价值,对存在内镜检查禁忌证者CT小肠成像可作为首选辅助检查手段.

abstractsObjective To investigate the value of double-balloon endoscopy for the diagnosis of small bowel Crohn disease(CD).Methods Data of 141 patients with suspected CD undergoing double-balloon endoscopy were reviewed.Diagnosis was made based on pathological,endoscopic findings and clinic follow-up results.Detection rates and diagnosis rates of small bowel CD were compared by double-balloon enteroscopy,CT enterography and capsule endoscopy.Results The detection and diagnosis rates of small bowel CD by double-balloon endoscopy were 90.8％ ( 128/141 ) and 98.4％ ( 126/128),respectively.These two variables by CT enterography were 76.0％ (19/25) and 89.5％ (17/19),and those by capsule endoscopy were 60.0％ (15/25) and 93.3％ (14/15).Conclusion Double balloon enteroscopy has high application value for the diagnosis of small bowel CD.For those contraindicated with endoscopy,CT enterography can be considered as a preferred auxiliary diagnostic modality.
