【摘要】：目的:观察应用二氧化碳(CO2)作为小肠CT仿真内镜(CTVE)造影介质的有效性与安全性。方法:选择疑为小肠疾病患者62例,随机数字表法分为观察组、空气组各31例。观察组以CO2作为成像介质、对照组以空气作为成像介质,行小肠CTVE检查。观察比较两组腹痛视觉模拟评分(VAS)、呼气末CO2分压(PETCO2)、肠道气体量等。结果 :检查后1 h观察组VAS评分明显低于对照组(P0.01),腹平片检查显示CO2组小肠气体量和大肠气体量均明显少于对照组(P0.01);两组检查前、后PETCO2值均无明显变化(P0.05);观察组和对照组诊断隆起性病变的有效率分别为91.67%、90.91%(P0.05);非隆起性病变诊断符合率分别为50.00%、44.0%。结论:在小肠CTVE检查时使用CO2介质安全可靠,可作为空气介质的替代物。
[Abstract]:Objective: to observe the efficacy and safety of using carbon dioxide (CO _ 2) as a medium for small intestinal CT virtual endoscopy (CTVEV). Methods: 62 patients with suspected intestinal diseases were randomly divided into two groups. CO2 was used as imaging medium in observation group and air as imaging medium in control group. The visual analogue score of abdominal pain (VAS), end expiratory CO2 score (PETCO _ 2) and intestinal gas volume were observed and compared between the two groups. Results: the VAS score of the observation group was significantly lower than that of the control group at 1 hour after examination, and the abdominal plain film examination showed that the small intestine of the CO2 group was significantly lower than that of the control group. The amount of gas and large intestine gas were significantly lower than that of control group (P 0.01). The effective rate of diagnosis of protuberant lesions in the observation group and control group was 91.67 and 90.91 respectively, and the coincidence rate in the diagnosis of non-protuberant lesions was 50.000 and 44.0 respectively. Conclusion: it is safe and reliable to use CO2 medium in small intestine CTVE examination. It can be used as a substitute for air media.
