目的探讨OMOM.胶囊内镜(CE)对不明原因消化道出血(OGIB)的诊断价值。方法分析58例OGIB患者CE胃内运行时间、小肠运行时间及OGIB的病变检出率、诊断率及病因分类。结果检查过程中无明显不适及并发症,全小肠检查成功率57/58(98.3%),CE在胃内运行时间平均为(30.9±16.5)min,在小肠内运行时间平均为(252.4±83.5)min,总病变检出率为53/58(91.4%),诊断率为41/58(70.7%),其中显性出血组病变检出率30/31(96.8%),诊断率为23/31(74.2%),隐形出血组病变检出率23/27(85.2%),诊断率为18/27(66.7%),后两组检出率及诊断率比较无明显差异(P>0.05)。血管病变是OGIB的主要病因,其次是非特异性小肠炎、小肠占位、NSAID相关性肠炎、Crohn病等。结论 CE对OGIB诊断率高、安全、无创伤,可作为OGIB的常规检查手段。
Objective To investigate the value of OMOM capsule endoscopy (CE) in the diagnosis of unexplained gastrointestinal bleeding (OGIB). Methods 58 cases of OGIB patients with gastric intragastric running time, small intestine run time and OGIB lesions detection rate, diagnosis rate and cause classification. Results There was no obvious discomfort and complication during the examination. The success rate of total small intestine examination was 57/58 (98.3%). The average running time of CE in the stomach was (30.9 ± 16.5) min and that in the small intestine was (252.4 ± 83.5) ) min, the total detection rate was 53/58 (91.4%), the diagnostic rate was 41/58 (70.7%), of which the detection rate was 30/31 (96.8%) in the dominant hemorrhage group and the diagnostic rate was 23 / 31 (74.2%). The detection rate of invisible hemorrhage group was 23/27 (85.2%), the diagnostic rate was 18/27 (66.7%). There was no significant difference in the detection rate and diagnosis rate between the two groups (P> 0.05) . Vascular disease is the main cause of OGIB, followed by non-specific enteritis, small intestine, NSAID-associated enteritis, Crohn’s disease and so on. Conclusion The diagnostic rate of OGIB by CE is safe, non-invasive and can be used as routine examination of OGIB.
