目的：探讨螺旋CT仿真内窥镜诊断梗阻性结肠占位的临床意义。方法收集本院2010年10月至2013年10月收治的梗阻性结肠占位患者57例，均采用螺旋CT仿真内窥镜检查和纤维结肠镜检查，评价螺旋CT仿真内镜诊断梗阻性结肠占位与纤维结肠镜诊断的符合率。结果螺旋CT仿真内窥镜诊断梗阻性结肠占位的整体符合率为89.4%，其对癌性梗阻诊断符合率为96.5%，对结肠外肿瘤压迫所致梗阻诊断符合率为75.0%，对急性假性肠梗阻诊断符合率为80.0%，对肠粘连所致肠梗阻诊断符合率为25.0%，对其他类型肠梗阻诊断符合率为100.0%。结论螺旋CT仿真内窥镜诊断梗阻性结肠占位安全无创，能够对梗阻性结肠占位进行定性诊断。%Objective To investigate the clinical signiifcance of spiral CT multiple simulation endoscopic in diagnosis obstructive colon occupying. Method 57 cases of patients with obstructive colon occupying were selected in our hospital from October 2010 to October 2013, all patients were detected with spiral CT multiple simulation endoscope and ifber colonoscopy appraised the coincidence rates of spiral CT multiple simulation endoscope with ifber colonoscopy. Result Total coincidence rate of spiral CT multiple simulation endoscope in diagnosis obstruction colon occupying was 89.4%, coincidence rate of multiple simulation endoscope in diagnosis colon obstruction with cancer was 96.5%, coincidence rate was 75.0%in diagnosis colon obstruction with exogenetic tumour constricts, coincidence rate was 80.0% in diagnosis colon obstruction with acute intestinal pseudo obstruction, coincidence rate was 25.0%in diagnosis colon obstruction with ankylenteron, and coincidence rate was 100.0%in colon obstruction with other reasons. Conclusion Spiral CT multiple simulation endoscope is noninvasive and safety, and could provide qualitative diagnosis for obstructive colon occupying.
