[目的]探讨术前经阴道行彩色多普勒声象图(TVCDS)检查,判断临床Ⅰ期子宫内膜癌浸润深度与病理T分期的准确性和临床价值。[方法]回顾性分析108例行TVCDS检查的临床Ⅰ期子宫内膜癌患者,根据声象图(BUS)特征和彩色血流(CDFI)特点及血流阻力指数(RI),判断肿瘤浸润深度,并与手术病理T分期结果对照分析。[结果]TVCDS测得子宫内膜厚度范围5.0～43mm,Ⅰa期子宫内膜厚度平均6.5mm,Ⅰb期18.6mm,Ⅰc期24.8mm;Ⅰa期CDFI显示率33.33%(5/15),Ⅰb期75%(30/56),Ⅰc期88.89%(32/37);Ⅰa期RI平均0.46,Ⅰb期为0.50,Ⅰc期0.55。TVCDS与手术病理T分期总符合率为73.15%(79/108),T1期符合率53.33%(8/15),T2期71.43%(40/56),T3期83.78%(31/37)。[结论]TVCDS可作为临床I期子宫内膜癌常规检查和术前预测病理T分期的方法之一,为选择手术方法和判断预后提供依据。
[Objective] To evaluate the accuracy and clinical value of transvaginal color Doppler echocardiography (TVCDS) before operation to determine the clinical stage I endometrial carcinoma infiltration depth and pathological T stage. [Methods] A total of 108 patients with clinical stage Ⅰ endometrial carcinoma undergoing TVCDS were retrospectively analyzed. The depth of tumor invasion was determined according to the characteristics of the BUS and the characteristics of color flow (CDFI) and the blood flow resistance index (RI) , And compared with the surgical pathological T staging results. [Results] The range of endometrial thickness was 5.0 ~ 43mm in TVCDS, 6.5mm in stage Ⅰa, 18.6mm in stage Ⅰb and 24.8mm in stage Ⅰc, and 33.33% (5/15) in stage Ⅰa. The stage Ⅰb 75% (30/56), 88.89% (Ⅰ) of stage Ⅰc, RI of stage Ⅰa was 0.46, stage Ⅰb was 0.50 and stage Ⅰc was 0.55. The total coincidence rate of TVCDS and surgical staging was 73.15% (79/108). The coincidence rate of T1 stage was 53.33% (8/15), that of T2D stage was 71.43% (40/56) and that of T3 stage was 83.78% (31/37). [Conclusion] TVCDS can be used as one of the routine clinical stage Ⅰ endometrial cancer screening and preoperative pathological T staging, and provide the basis for the selection of surgical methods and prognosis.
