MSCT与胶囊内镜对不明原因消化道出血的诊断价值研究

Diagnostic Value of MSCT and Capsule Endoscopy in Unexplained Gastrointestinal Bleeding

目的探究多层螺旋CT(MSCT)及胶囊内镜(CE)对不明原因消化道出血的诊断价值。方法回顾性分析我院采用MSCT及CE检查的不明原因消化道出血患者的临床资料,其中行MSCT检查者79例,行CE检查者64例,所有患者均经双气囊小肠镜或血管造影或手术探查等手段证实。结果MSCT检查共检出病灶38例(48.10%),33例(86.84%)确诊为阳性;CE检查共检出36例病灶,其中29例(80.56%)确诊为阳性;两种方法诊断阳性预测值比较差异无统计学意义(χ2=0.171,P=0.679)。结论MSCT及CE对不明原因消化道出血均有一定诊断价值,CE直观显示病变的大体改变,MSCT进一步明确病变浸润深度、范围,二者结合有助于提高诊断准确性。

Objective To investigate the diagnostic value of multi-slice spiral CT(MSCT)and capsule endoscopy(CE)in unexplained gastrointestinal bleeding.Methods The clinical data of patients with unexplained gastrointestinal bleeding examined by MSCT and CE were analyzed retrospectively.Among them,79 cases underwent MSCT and 64 cases underwent CE examination.All patients were confirmed by double balloon endoscopy,angiography or surgical exploration.Results There were 38 cases(48.10%)with lesions detected by MSCT and 33 cases(86.84%)with positive status.There were 36 cases with lesions detected by CE examination and 29 cases(80.56%)with positive status.There was no significant difference in positive predictive values by the two methods(χ2=0.171,P=0.679).Conclusion Both of MSCT and CE have certain diagnostic value for unexplained gastrointestinal bleeding.CE can directly show the general changes of the lesions.MSCT can further clarify the depth and scope of the lesions.The combination of MSCT and CE is helpful to improve the diagnostic accuracy.
