双气囊推进式小肠镜对98例小肠疾病的诊断价值

The diagnosis value of double-balloon enteroscopy in 98 patients with small intestinal diseases

目的:分析双气囊推进式小肠镜(double-balloon enteroscopy,DBE)在小肠疾病诊断中的价值。方法:回顾性分析我院2005年9月～2008年12月疑有小肠疾病的患者的资料,对经常规上、下消化道内镜检查均无异常发现的患者行DBE检查,并对其临床相关资料进行分析。结果:本研究共包括98例患者(男64例,女34例),平均年龄55.7岁,其中51例表现为不明原因反复发作的消化道出血,34例表现为腹痛、腹胀,13例表现为肠梗阻。共进行了115例次DBE检查,所有病例均成功插入小肠,平均检查时间为72.8min,其中经口检查35例,经肛检查63例,13例分别经口和经肛检查。DBE检查发现的小肠病变共74例(75.5%);5例病灶发生在常规上消化道内镜检查所能观察到的范围内。最常见的病变为小肠肿瘤(39.1%)和血管扩张(29.7%)。结论:DBE检查对小肠疾病具有较高的诊断价值,而且安全、可靠。

Objective To evaluate the diagnostic value of double -balloon enteroscopy （DBE） in the diagnosis of small intestinal diseases. Method The patients with suspected small intestinal diseases in our hospital from Sep 2005 to Dec 2008 were performed double - balloon enteroscopy（DBE）. Their data were analyzed. Results Total 98 patients （64 male,34 female） were studied,with a mean age of 55.7 years. For 51 patients presented with obscure recurrent gastrointestinal bleeding,34 patients presented abdominal pain, while 13 patients had small intestinal obstruction. A total of 115 DBEs were performed with a mean procedure duration of 72. 8 minutes. Antegrade and retrograde approaches were performed on 35 and 63 patients, respectively, and 13 patients had a combination of both routes. The lesions were found in 74 of 98 patients with a total positive rate of 75.5%. Five lesions were found within the reach of a standard upper endoscope. Total 31.1% patients had surgery procedures after DBE exam. Conclusion DBE has a high diagnostic value in patients with previously negative upper and lower endoscopic results. It is safe and effective.
