OMOM智能胶囊内镜系统临床应用111例分析

Clinical application of OMOM capsule endoscopy in 111 cases

目的探讨OMOM智能胶囊内镜系统(OMOM胶囊内镜)对小肠疾病的诊断价值。方法总结分析我院不明原因消化道出血(OGIB)及慢性腹痛、腹胀、腹泻等患者共111例,所有患者进行胶囊内镜检查前均行胃镜、肠镜及腹部CT检查,未发现可解释疾病的病因。分析胶囊内镜胃内运行时间、小肠运行时间及胶囊内镜对各类症状组检出疾病的检出率、诊断符合率。结果 111例患者检查过程中无明显不适及并发症,全小肠检查成功率96.4%(107/111),胶囊内镜在胃内运行时间平均为(41±18)min,在小肠内运行时间平均为(292±88)min。总病变检出率为82.9%(92/111),诊断符合率为50.5%(56/111),其中OGIB组病变检出率95.5%(42/44),诊断符合率为68.2%(30/44),慢性腹痛组病变检出率为78.3%(36/46),诊断符合率为39.1%(18/46),慢性腹胀组病变检出率为81.8%(9/11),诊断符合率为27.3%(3/11),慢性腹泻病组变检出率为50%(5/10),诊断符合率为20%(2/10)。OGIB组病变检出率和诊断符合率明显高于其他3组(P<0.05)。结论国产OMOM胶囊内镜对小肠疾病诊断率高、安全、无创伤。可作为小肠疾病的常规检查手段,尤其是OGIB的诊断。

Objective To explore the evaluation of OMOM capsule endoscopy in the diagnosis of the small-bowel disease. Methods One hundred and eleven patients of clinic with unclear digestive tract hemorrhage , abdominal pain, distention and diarrhea in our hospital received examination of OMOM capsule endoscopy. Before the examination , all patients underwent gastro scopy, colonoscopy and abdominal CT, but the results were negative. Gastric and small bowel transit time, complication, detection rate and diagnostic yield were valuated. Results One hundred and eleven patients had no discomfortable feeling and complication during the examination , achievement ratio was 96.4%（56/111）. The capsule endoscopy remained in the stomach for an average of （41±18） min. The mean transit time in the small bowel was （292 ±88） min. The detection rate and diagnostic rate of all patients were 82.9%（92/111）, and 50.5%（56/111）, the OGIB group 95.5%（42/44） and 68.2%（30/44）, the Chronic abdominal pain group 78.3%（36/46） and 39.1%（18/46）, the abdominal distention group 81.8%（9/11） and 27.3%（3/11）, the chronic diarrhea group 50%（5/10） and 20%（2/10）. The detection rate and diagnostic yield of the OGIB group were significantly higher than the three groups in also （P〈0.05）. Conclusion OMOM capsule endoscopy has high diagnostic rate in small-bowel disease because it is safe and atraumatic. It can be used in finding small intestinal disease, especially in patients with obscure gastrointestinal bleeding.
