  • 摘要:
      目的  探讨大肠、小肠双充盈法肠道CT造影对不明原因消化道出血(OGIB)的诊断价值。
      方法  回顾40例OGIB患者的临床资料, 患者均进行大肠、小肠双充盈法肠道CT造影及胶囊内镜检查，按检查方法分别设为CT组、内镜组，分析大肠、小肠双充盈法肠道CT造影检查的价值。
      结果  CT组总体病灶检出率为75.00%, 显性出血率60.00%、隐性出血率40.00%, 内镜组总体病灶检出率为85.00%, 显性出血率67.65%、隐性出血率32.35%, 2组无显著差异(P>0.05)。CT组敏感度、特异度分别为61.54%、85.71%, 内镜组敏感度、特异度分别为76.00%、73.33%, 组间差异显著(P < 0.05)。
      结论  大肠、小肠双充盈法肠道CT造影对OGIB具有明显的诊断效果。

     

    Abstract:
      Objective  To investigate the diagnostic value of intestinal CT by double filling method of large and small intestine in diagnosis of obscure gastrointestinal bleeding (OGIB).
      Methods  A retrospective study of 40 patients with OGIB admitted to our hospital were performed in our hospital with double-filled intestine CT and capsule endoscopy, and were divided into CT group and endoscopy group. The value of intestine CT imaging of large intestine double filling method were analyzed.
      Results  The overall detection rate of the CT group was 75.00%, the dominant bleeding rate was 60.0%, the occult bleeding rate was 40.00%, the total lesion detection rate in the endoscopy group was 85.00%. The dominant bleeding rate was 67.65%, and the occult bleeding rate was 32.35%, no significant differences were found in two groups (P>0.05). The sensitivity and specificity of CT group were 61.54% and 85.71%, respectively, and 76.00% and 73.33%, respectively, in the endoscopy group, significant differences were found in two groups (P < 0.05).
      Conclusion  Intestinal CT angiography with double filling method in double intestine has obvious diagnostic effects on OGIB.
