Endorectal ultrasound was used prospectively to stage 85 patients with rectal cancer. All patients had surgical exploration and histological analysis. Demonstration of tumour, extension into perirectal fat and lymph node involvement were evaluated. Eighty-one tumours were successfully imaged by endorectal ultrasound. The results suggest that: endorectal ultrasound is more accurate than CT in detecting the site of tumour; endorectal ultrasound is more accurate than CT in detecting perirectal fat infiltration; endorectal ultrasound is slightly more accurate than CT in detecting level II lymph node involvement.
前瞻性地采用直肠内超声对85例直肠癌患者进行分期。所有患者均接受了手术探查和组织学分析。评估肿瘤的显示情况、向直肠周围脂肪的浸润情况以及淋巴结受累情况。81例肿瘤通过直肠内超声成功成像。结果表明：在检测肿瘤部位方面，直肠内超声比CT更准确；在检测直肠周围脂肪浸润方面，直肠内超声比CT更准确；在检测Ⅱ级淋巴结受累方面，直肠内超声比CT稍准确。
