摘要
目的:探讨经直肠双平面超声联合超声造影在直肠癌术前T分期中的价值。方法:回顾性分析新疆医科大学第一附属医院2014年3月至2015年3月75例经病理确诊直肠癌患者术前行经直肠双平面超声(TRUS)联合超声造影检查及多层螺旋CT检查(MSCT),观察肿瘤的位置,边界,内部回声,造影后的增强模式及肿瘤的内部微循环灌注,在MSCT扫描下的直肠壁的厚度改变及密度变化,分别将诊断结果与术后病理结果进行对照。结果:术前经直肠双平面超声联合超声造影检查对直肠癌T分期总准确率为84%,T_1、T_2、T_3、T_4期的灵敏度分别为75%、75%、97.1%、66.7%,特异度分别为100%、92.7%、82.1%、98.5%;MSCT诊断直肠癌的总准确率为46.7%,T_1、T_2、T_3、T_4期的灵敏度分别为8.3%、60%、47.2%、71.4%,特异度分别为100%、50.9%、74.3%、95.5%,两者差异有统计学意义(P<0.05)。结论:经直肠双平面超声联合超声造影能清晰的观察肿瘤侵犯直肠肠壁层次,肿瘤内部微循环及血流供应,在直肠癌的术前T分期中有着较为明显的诊断优势。
Objective： To evaluate the value of double-plane transrectal ultrasound combined with contrast preoperative T staging of rectal carcinoma. Methods： Retrospective analyse 75 patients with pathologically confirmed rectal carcinoma then staged by double-plane transrectal ultrasound（TRUS）combined with contrast and multislice spiral CT（MSCT）examination, Observe the location of the tumor boundary, internal echo, Mode of enhancement and internal tumor microcirculation after contrast, Rectal wall thickness and density changes under MSCT scanning, comparing the diagnostic results with pathological results. Results： The accuracy of TRUS combined with contrast and MSCT in determining the T staging of colorectal cancer were 84% and,the accuracy were（T_1 75%,T_2 75%,T_3 97.1%,T_4 66.7%）and（T_1 8.3%、T_2 60%、T_3 47.2%、T_4 71.4%）, the specificity were（T_1 100%,T_2 92.7%,T_3 82.1%,T_4 98.1%）and（T_1 100%、T_2 50.9%、T_3 74.3%、T_4 95.5%）respectively. There was statistically significant between the two methods. Conclusion： TRUS combined with ultrasound contrast can clearly observe tumor invasion of the rectum intestinal level, Internal tumor microcirculation and blood supply,and has more significant diagnostic advantage In rectal cancer preoperative T staging.
