目的研究64排螺旋CT仿真结肠镜诊断对结直肠占位性病变的临床价值。方法选择2013年6月至2015年6月于广州市中西医结合医院就诊的56例结直肠占位性病变的患者作为研究对象,在电子结肠镜检查的前提下,分别利用常规CT检查和64排螺旋CT仿真结肠镜(CTC)对此类患者进行辅助诊断,并按照诊断方式的不同分成常规CT检查组(A组)和64排螺旋CT仿真结肠镜组(B组),比较两种方法对结直肠占位性病变的诊断效果。结果 A组检查准确率为73.21%,显著低于B组(94.64%);A组出现未检/漏诊的比率为19.64%,B组为1.79%;A组对于≤5 mm的息肉的检查数目显著低于B组,差异均有统计学意义(P<0.05)。两种方法下参与人员对其操作简单性评分比较差异未见统计学意义;但B组图像判断的准确性和实用性评分均显著高于A组,差异均有统计学意义(P<0.05)。结论在常规电子结肠镜无法诊断时采用64排螺旋CT仿真结肠镜进行辅助诊治的效果更好,成像清晰精确,对于结直肠占位性病变的诊断具有重要意义,实用性强,值得临床推荐。
Objective To study the clinical value of 64-slice spiral CT virtual colonoscopy in the diagnosis of colorectal lesions. Methods From June 2013 to June 2015, 56 patients with colorectal space-occupying lesions treated in Guangzhou General Hospital of Integrated Traditional and Western Medicine were enrolled in this study. Under the condition of electronic colonoscopy, conventional CT and 64 These patients were assisted by CTC and were divided into routine CT examination group (group A) and 64-slice spiral CT simulation colonoscopy group (group B) according to different diagnostic methods. Two methods were compared The diagnosis of colorectal space-occupying lesions. Results The accuracy of examination in group A was 73.21%, which was significantly lower than that in group B (94.64%). The rate of unchecked / missed diagnosis in group A was 19.64%, and in group B was 1.79%. The number of polyps in group A was less than 5 mm Significantly lower than that in group B, the difference was statistically significant (P <0.05). There was no significant difference between the two methods in assessing the operational simplicity of patients. However, the accuracy and practicality of image judgment in group B were significantly higher than those in group A (P <0.05 ). Conclusion The conventional colonoscopy can not be diagnosed with 64-slice spiral CT colonoscopy for diagnosis and treatment of better effect, clear and accurate imaging for the diagnosis of colorectal space occupying lesions of great significance and practicality, it is worth recommending.
