摘　　要：目的探讨经直肠超声在低位直肠癌放疗术后分期中的临床意义。方法经直肠端视式探头对128例低位直肠癌患者常规进行放疗前超声分期,放疗后1周,3,6,12个月经直肠超声评估病灶。结果放疗术后1周经直肠超声检查,对直肠癌病灶T1、T2期有过度分期的现象,而T3期病灶则有过低分期的现象,对T4期的病灶的分期准确率最为一致。随着放疗后时间的推移,病灶周边淋巴结数目增加,T3、T4期病灶复发的增多与淋巴结转移病灶增加的趋势相关。结论经直肠超声分期对直肠癌放疗具有重要的指导价值,但是端视式腔内探头有一定局限性,应予以重视。Objective To investigate the clinical value of lowing set rectal carcinoma staging after radiotherapy by transrectal ultrasound. Methods One hundred and twenty -eight patients with lowing set rectal carcinoma were staged before radiotherapy by endorectal end view probe. Then the lesions were evaluated at the 1st week, 3rd month, 6th month and 12th month after radiotherapy, respectively. Results At the 1 st week after radiotherapy, there was over staging for stage T1 - T2 rectal carcinoma by transrectal uhrasonography, while there was lower staging for stage T3 lesions, and it had a well consistence with staging accuracy rate for stage T4 lesions. After radiotherapy, the lymph node numbers in peripheral lesion was increased with the time delayed, and the increased recurrence lesions of T3 , T4 was also consistent with the increased lymph nodes metastasis. Conclusion Transrectal ultrasound staging has important value for radiotherapy of rectal carcinoma, but we have to pay attention to the limitations of transrectal end view probe.
