| 目的 评价耦合剂充盈法腔内超声在直肠癌术前T分期诊断中的价值。方法 对115例直肠癌患者行耦合剂充盈法腔内超声检查,进行术前T分期,并与手术及术后病理分期对照。结果 115例直肠癌术前T分期诊断总符合率89.57％,T1、T2、T3、T4期诊断灵敏度和特异度分别为93.10％、61.11％、96.61％、88.89％和97.67％、96.91％、89.29％、99.06％;过度判断6.96％(8/115),判断不足3.48％(4/115)。结论 耦合剂充盈法腔内超声在直肠癌术前T分期诊断中有重要价值。 |

| Objective To evaluate the role of endorectal ultrasonography with coupling gel intrarectal filling in preoperative T stage of rectal cancer. Methods One hundred and fifteen patients with rectal cancer underwent endorectal ultrasonography with coupling gel intrarectal filling. The preoperative T stage according to ultrasonic manifestations was compared with histological findings. Results The total diagnostic accordance rate of preoperative T stage by endorectal ultrasonography with coupling gel intrarectal filling was 89.57%. The sensitivity of ultrasonography for T1, T2, T3 and T4 was 93.10%, 61.11%, 96.61%, 88.89%, while the specificity was 97.67%, 96.91%, 89.29%, 99.06%, respectively. The overstaging rate of ultrasonography was 6.96% (8/115), and the understaging rate was 3.48% (4/115). Conclusion Endorectal ultrasonography with coupling gel intrarectal filling is a valuable diagnostic method for T stage of rectal cancer. |
