推进式双气囊电子小肠镜对儿童小肠疾病诊断的研究

目的评价双气囊电子小肠镜在儿童中应用的安全性、检查范围、临床价值。方法2003年6月—2005年5月,对14例年龄在3～14岁,经多项常规检查阴性,怀疑为小肠疾病的患儿行双气囊电子小肠镜检查。其中13例为原因不明的消化道出血、缺铁性贫血,1例为慢性腹泻。结果双气囊电子小肠镜抵达空、回肠交界部2例,回肠中下端10例和末端回肠2例,检查所用时间分别为,空、回肠交界部40～50min,回肠中下端55～70min和末端回肠78～89min。14例受检患儿中,12例发现病灶,阳性检出率为85．7％。未见操作相关的严重不良反应和并发症。结论双气囊电子小肠是诊断小肠疾病较好的检查手段,在儿童中应用是安全、可行的。

Application of double-balloon push enteroscopy in diagnosis of small bowel disease in children

Objective Double-ballon enteroscopy is a new method that allows complete visualization of the lumen of small bowel This study was conducted to evaluate safety, extent of observation and clinical efficacy of double-balloon push enteroscopy in diagnosis of patients with small bowel disease in children. Methods Fourteen cases suspected of small bowel diseases with negative findings on examinations with various routine diagnostic modalities underwent double-balloon push enteroscopy from June, 2003 to May, 2005. Of the 14 cases, 13 had gastrointestinal bleeding and iron deficient anemia and 1 case had chronic diarrhea, the causes of these conditions were unknown. Results The enteroscopy reached jejunal- ileum transitional area, middle or lower portion of ileum and terminal ileum in 2, 10 and 2 cases, and the examination time was 40 - 50 min, 55 - 70 min and 78 - 89 min, respectively. Lesions were detected in 12 of 14 the cases. The positive diagnostic rate was 85.7%. There were no relevant technical problems or severe complications. Conclusion Double-ballon push enteroscopy is a safe, reliable diagnostic modality of high clinical value for small bowel diseases in children.
