摘要
目的:探讨经直肠腔内超声(transrectal ultrasound,TRUS)检测直肠癌内部动脉血流动力学变化情况与直肠癌病理分期的关系.方法:对240例经病理活检证实为直肠癌患者术前行TRUS检查,常规检测肿瘤内部动脉血流动力学参数值[阻力指数(resistance index,RI)、搏动指数(pulsatility index,PI)、峰值流速(peak flow velocity,PSV)、舒张末期容积(end-diastolic volume,EDV)],术后根据病理分期对参数值分组并进行回顾性分析,比较分析各组间的参数.结果:血流动力学参数中,RI、PI随着病理分期的升高而降低,PSV、EDV则随着病理分期的升高而升高;PI、RI与病理分期均呈负相关(r=-0.680,r=-0.470,P=0.000),PSV、EDV与病理分期均呈正相关(r=0.200,r=0.289,P=0.000).结论:常规检测直肠癌内部动脉血流动力学参数RI、PI、PSV、EDV,可为评估直肠癌临床分期提供重要的参考价值.
AIM： To investigate the relationship between the blood flow dynamics detected by transrectal ultrasound （TRUS） and the pathological stage of rectal cancer. METHODS： A total of 240 patients with pathologically confirmed rectal cancer who underwent TRUS before operation were included. The hemodynamic parameters （PI, PSV, RI, and EDV） of the tumor were routinely detected. According to the pathological stage, the parameters were analyzed retrospectively and compared. RESULTS： PI and RI decreased with the increase of the pathological stage, and EDV and PSV increased with the increase of the pathological stage. PI and RI were negatively correlated with pathology （r = -0.680, -0.470; P = 0.000, 0.000）. PSV and EDV were positively correlated with pathology （r = 0.200, 0.289; P = 0.000, 0.000）. CONCLUSION： Detection of conventional arterial hernodynamic parameters （PI, PSV, RL and EDV） can provide important and valuable information for clinical staging of rectal cancer.
