为了评价摇篮体位技术结肠灌注CT扫描在结肠癌术前分期的价值,将130例结肠癌患者根据病变部位采取不同的摇篮体位,检查前低张肠道自肛门注入800～1 200mL的温水,增强CT扫描。右半结肠肿瘤取右侧卧位,左半结肠取左侧卧位。根据肿瘤的浸润程度和淋巴结情况进行CT分期,并与术后病理分期对照。术前CT分期T1低估3例,T2分别高估1例和低估4例,T3高估3例和低估3例,T4高估1例。T1分期准确率76.9%(10/13),T2准确率85.7%(30/35),T3准确率90.6%(58/64),T4准确率94.4%(17/18)。切除送检910个淋巴结中,CT检出581个,敏感性63.8%。送检淋巴结中确诊转移390个,CT诊断转移341例,特异性为87.4%。初步研究结果提示,摇篮体位技术结肠灌注CT扫描能够对结肠癌进行术前准确分期,为临床决策治疗提供有价值的信息。
In order to evaluate the value of cradle position CT perfusion in the preoperative staging of colon cancer, 130 cases of colon cancer patients were taken different cradle position according to the lesion site, 800 ~ 1200mL warm water was infused from the anus before the examination, CT scan. The right colon cancer right lateral decubitus, left colon and left lateral position. According to the extent of tumor invasion and lymph node CT staging, and postoperative pathological staging control. Preoperative CT staging T1 underestimated 3 cases, T2 were overestimated in 1 case and underestimated in 4 cases, T3 overestimated in 3 cases and underestimated in 3 cases, T4 overestimated in 1 case. T1 staging accuracy was 76.9% (10/13), T2 accuracy was 85.7% (30/35), T3 accuracy was 90.6% (58/64) and T4 accuracy was 94.4% (17/18). Among the 910 lymph nodes examined and dissected, 581 were detected by CT, with a sensitivity of 63.8%. 390 lymph node metastases confirmed diagnosis, 341 cases of CT diagnosis and transfer, the specificity was 87.4%. Preliminary findings suggest that cradle position technique colon perfusion CT scan can accurately stage colon cancer preoperatively and provide valuable information for clinical decision-making and treatment.
