【摘要】 目的探究直肠内充气多层螺旋CT(MSCT)对直肠癌术前肠系膜浸润及淋巴结转移分期的评估价值。方法选取2013年1月至2016年5月间深圳市龙岗区第六人民医院收治的84例经手术病理确诊的直肠癌患者,均行MSCT检查和常规螺旋CT增强扫描检查,以术后病理结果为金标准,对比两种检查方法诊断正确率。结果 MSCT检查对肠系膜浸润和淋巴结转移诊断准确率分别为90.5%(76/84)和89.3%(75/84),均显著高于常规螺旋CT增强扫描的61.9%(52/84)和64.3%(54/84),差异均有统计学意义(均P<0.05)。MSCT检查诊断不同浸润程度的直肠癌术前肠系膜浸润准确性,均显著高于常规螺旋CT增强扫描,差异均有统计学意义(均P<0.05);MSCT检查对直肠癌术前淋巴结转移分期中N0和N1期的诊断准确性均显著高于常规螺旋CT增强扫描,差异均有统计学意义(均P<0.05)。结论 MSCT对直肠癌术前肠系膜浸润及淋巴结转移分期的诊断准确性较高,可作为临床上首选的诊断方式。更多还原

【Abstract】 Objective To study the inflatable rectal multislice spiral computed tomography( MSCT) in assessing the preoperative mesenteric infiltration and stages of lymph node metastases from rectal cancer. Methods Eighty-four patients who were diagnosed with rectal cancer by operation and pathology were selected at The Sixth People’s Hospital of Longgang District from January 2013 to May 2016. All the patients underwent MSCT examination and conventional enhanced spiral CT scanning. The postoperative pathological results were considered as the gold standard,and the diagnostic accuracy was compared between the two kinds of diagnostic approaches. Results The diagnostic accuracy of MSCT examination was90. 5%( 76/84) and 89. 3%( 75/84) for mesenteric infiltration and lymph node metastases,respectively,which was significantly higher than 61. 9%( 52/84) and 64. 3%( 54/84) of the conventional enhanced spiral CT scanning( all P < 0. 05). The accuracy of MSCT in the diagnosis of variable degrees of preoperative mesenteric infiltration and lymph node metastases was significantly higher than that of the conventional enhanced spiral CT scanning( P < 0. 05). The accuracy of MSCT in the diagnosis of preoperative stage N0 and N1 lymph node metastases from rectal cancer was significantly higher than that of the conventional enhanced spiral CT scanning( all P < 0. 05). Conclusion MSCT shows high diagnostic accuracy in assessing the preoperative mesenteric infiltration and stages of lymph node metastases from rectal cancer which can be clinically used as the preferred diagnostic method.更多还原
