Twenty-five intrarectal ultrasound (US) scannings were performed preoperatively for assessing the depth of infiltration of rectal neoplasms. One tumour located in the distal rectum could not be visualized on the ultrasonogram. US could correctly identify extraintestinal infiltration in 13 out of 14 cases with proved extrarectal involvement on histopathological examination. The overall accuracy of US in demonstrating tumour growth outside the rectal wall was 88%, sensitivity 93% and specificity 80%. Intrarectal US is a useful additional method in the preoperative evaluation of rectal neoplasms and provides more information about the depth of tumor infiltration compared with conventional methods thus helping decide the most appropriate therapy for the patient.
术前进行了25次直肠内超声（US）扫描，以评估直肠肿瘤的浸润深度。1例位于直肠远端的肿瘤在超声检查中未能显示。在14例经组织病理学检查证实有直肠外侵犯的病例中，超声能正确识别13例的肠外浸润。超声显示直肠壁外肿瘤生长的总体准确率为88%，敏感性为93%，特异性为80%。直肠内超声是直肠肿瘤术前评估中一种有用的辅助方法，与传统方法相比，它能提供更多关于肿瘤浸润深度的信息，从而有助于为患者确定最合适的治疗方案。
