【摘要】 目的评价双气囊小肠镜对小肠疾病的诊断价值及安全性和耐受性。方法 2003年5月至2005年7月,对68例经常规检查无异常发现、疑患小肠疾病患者进行双气囊小肠镜检查,其中不明原因反复消化道出血39例、不完全性小肠梗阻7例、慢性腹痛14例、慢性腹泻8例。结果 68例患者中, 3b例经口进镜,25例经肛进镜。7例患者分别经口及经肛进镜检查。除3例因肠腔狭窄中止进镜外,其余病例均能检查1／2-3／4的小肠,7例患者结合经口及经肛途径完成全小肠检查。68例患者中41例检出阳性病灶,总阳性率为60．3％;其中不明原因消化道出血阳性率为62．6％(26／39),不完全性小肠梗阻阳性5例,慢性腹痛阳性率为43％(6／14),慢性腹泻阳性4例。除11例经口进镜者行异丙芬静脉全身麻醉外,其他经口及经肛进镜患者均能耐受整个检查,未出现出血、穿孔等严重并发症。结论双气囊小肠镜是一种对小肠疾病诊断价值较高、安全可靠的检查手段。更多还原

【Abstract】 Objective To evaluate the diagnostic value, patients’ tolerance and complications of double-balloon enteroscopy (DBE) in the diagnosis of small intestinal diseases. Methods During May 2003 to July 2005, a total of 68 patients (36 men, 32 women; mean age of 52. 6 years, range 15-78 years) with suspected small intestinal diseases were performed double-balloon enteroscopy (36 via mouth, 25 via anus and 7 via both mouth and anus according to suspected lesion location). Among them, obscure recurrent gastrointestinal bleeding was found in 39 cases, incomplete small intestinal obstruction in 7 cases, chronic abdominal pain in 14 cases, and chronic diarrhea in 8 cases. Results Approximately one half to three-fourth of the entire small intestine was observed by each approach in all cases except for 3 cases of severe intestinal stricture. The observation of the whole small intestine was finished by the combination of both oral and anal approaches in 7 cases. The appropriate use of X-ray made the enteroscopy easier and more helpful to determine the extent and location of the lesions. The lesions were found in 41 of the 68 patients, with a total positive rate of 60. 3%. The diagnostics yields was 26/39(62. 6%) in obscure recurrent gastrointestinal bleeding, 5 in incomplete intestinal obstruction, 6/14(43%) in chronic abdominal pain and 4 in chronic diarrhea, respectively. Fifty-seven cases (83. 8%) tolerated well without anesthesia while 11 cases received propofol anesthesia. No procedure-related severe adverse events or severe complications such as hemorrhage or perforation occurred in all cases. Conclusion Double-balloon enteroscopy is a well-tolerated and safe diagnostic approach with a high diagnostic yield in small intestinal diseases.更多还原
