目的探讨口服等渗甘露醇多排螺旋CT肠造影对小肠肿瘤的诊断应用。方法 84例小肠肿瘤患者,随机分为观察组与对照组,各42例。对照组患者服用5%泛影葡胺阳性对比剂并予以传统扫描,观察组患者口服等渗甘露醇行多排螺旋CT肠造影,通过专业医师评价后,对比两组患者的诊断结果。结果对照组患者的扫描结果与临床诊断符合率为76.19%(32/42),观察组患者的扫描结果与临床诊断符合率为95.24%(40/42),对比两组方法诊断符合率,差异具有统计学意义(χ2=6.222,P=0.013<0.05)。结论口服等渗甘露醇后行多排螺旋CT肠造影是一种简易且安全可行的方式,能够有效评价小肠肿瘤,能明显增加肿瘤的检出率,值得在临床上大力推广及应用。
Objective To investigate the diagnostic application of oral isotonic mannitol multi-slice spiral CT intestinal angiography for small intestinal tumors. Methods Eighty-four patients with small bowel cancer were randomly divided into observation group and control group, with 42 cases in each group. Patients in the control group were given 5% diatrizoate-positive contrast agent and were screened. The patients in the observation group were given oral isotonic mannitol for multi-slice CT angiography. The results of the two groups of patients were compared after evaluation by a professional physician. Results In the control group, the coincidence rate of the scan result and clinical diagnosis was 76.19% (32/42). The coincidence rate of the scan result and the clinical diagnosis in the observation group was 95.24% (40/42). Comparing the diagnostic accuracy and the difference between the two groups Statistically significant (χ2 = 6.222, P = 0.013 <0.05). Conclusions Multislice CT angiography is an easy, safe and feasible method after oral administration of isotonic mannitol. It can effectively evaluate the small intestine tumor and can significantly increase the detection rate of tumors. It is worth to be popularized and applied clinically.
