Abstract:
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.
