目的评价双气囊电子小肠镜对不明原因消化道出血的诊断价值和安全性及耐受性。方法2006年10月至2007年9月,在异丙酚静脉麻醉辅助下,对76例不明原因消化道出血患者施行双气囊电子小肠镜检查。结果76例患者中发现病变63例,病变检出率为82.9%。包括单发或多发性小肠溃疡17例,非特异性炎症9例,钩虫病7例,息肉病6例,血管畸形6例,憩室病4例(其中美克尔憩室3例),克罗恩病4例,间质瘤4例,高分化腺癌3例,十二指肠溃疡2例,蛔虫1例,未见明显异常13例。所有患者均顺利完成检查,未发生出血、穿孔等严重并发症,也未出现麻醉并发症或麻醉意外。结论双气囊电子小肠镜对不明原因消化道出血具有较高病变检出率和病因诊断准确率,是一种安全、可靠的检查手段。
Objective To evaluate the diagnostic value, safety and tolerability of double-balloon enteroscopy for gastrointestinal bleeding of unknown origin. Methods From October 2006 to September 2007, 76 patients with unexplained gastrointestinal bleeding underwent balloon double electron microscopy with the aid of propofol intravenous anesthesia. Results Sixty-six lesions were found in 76 patients. The detection rate of lesions was 82.9%. Including single or multiple small intestinal ulcer in 17 cases, nonspecific inflammation in 9 cases, 7 cases of hookworm, polyposis in 6 cases, vascular malformations in 6 cases, diverticular disease in 4 cases (including 3 cases of merkel diverticulum), Crohn 4 cases of disease, 4 cases of stromal tumors, 3 cases of well-differentiated adenocarcinoma, duodenal ulcer in 2 cases, roundworm in 1 case, no obvious abnormalities in 13 cases. All patients were successfully completed the examination, no bleeding, perforation and other serious complications, nor anesthesia complications or anesthesia accidents. Conclusions Double balloon enteroscopy has a high detection rate and accurate diagnosis of etiology of gastrointestinal bleeding of unknown origin, which is a safe and reliable method for the examination.
