单气囊小肠镜在小肠疾病中的应用

Application of single balloon enteroscopy in small intestinal diseases

目的:分析单气囊小肠镜检查疑似小肠疾病的特点及临床应用价值。方法:114例疑似小肠疾病患者,行单气囊小肠镜检查,观察其进镜方式、进镜时间、患者的耐受性、疾病诊断、检出率及并发症的发生率。结果:共进行152次检查,经口进镜83例次,经肛进镜69例次;检出的小肠病变84例,检出率73.7%;单气囊小肠镜对不明原因消化道出血的检出率明显高于腹痛、腹泻待查等患者(P<0.05);检出疾病主要有肿瘤性病变、非特异性小肠炎、克隆恩病、肠结核、血管病变、淋巴瘤等。经口进镜时间明显短于经肛进镜(P<0.05);患者耐受性好,无并发症发生。结论:单气囊小肠镜是目前诊断小肠疾病的安全可靠方法。

Objective：To analyze the peculiarity and diagnosis value of single balloon enteroscopy （SBE） in patients with suspected small bowel disease. Methods： From May 2011 to February 2013, 114 patients with sus- pected small bowel diseases underwent SBE examination were observed with clinical symptom, diagnosis, mode and time of thread, patients tolerance, the rate of positive eases and occurrence of complication. Results：A total of 152 single- balloon endoscopy examinations were performed in 114 suspected patients, 83 were performed via mouth and 49 were performed via anus. There were 84 positive cases, included tumour, nonspecific small bowel inflamma- tion,crohn disease , tuberculosis of intestines, intestinal blood vessel disease and lymphoma. The whole detection rates was 73.7%. The positive detection rate of obscure alimentary tract hemorrhage were significantly higher than that of abdominal pain and diarrhea （ P 〈 0.05 ）. The time of examination via mouth was shorter than that of via anus（ P 〈 0.05 ） , and patients tolerance were better via mouth without complications. Conclusion ： SBE examination is an effective method in the diagnosis of small bowel diseases.
