Preoperative evaluation of the depth of invasion in the rectal wall as well as the presence of regional metastatic nodes are considered important factors in order to decide surgical treatment as well as prognosis in cases of cancer of the rectum. This investigation was carried out in order to establish how usefull transrectal ultrasound was for the pre-operative evaluation of cancer of the rectum. We studied 78 patients with different ano rectal pathology, among them 40 patients with confirmed ADC of the rectum that were completely studied and had ultra sonographic as well as surgical and pathological staging using TNM classification. Confiability indicators of transrectal ultrasound when compared with pathology findings, showed a sensibility of 100% in T1-T2 and T4; in T3 lesions sensibility was 76%. Specificity was between 94% and 100% in all stages. We believe that trans-rectal ultrasound is a usefull, precise and reliable diagnostic tool, for staging purposes of rectal carcinoma.
术前评估直肠壁浸润深度以及区域转移淋巴结的存在情况，被认为是决定直肠癌手术治疗方案及预后的重要因素。开展此项研究是为了确定经直肠超声在直肠癌术前评估中的有用程度。我们研究了78例患有不同肛肠疾病的患者，其中40例经确诊为直肠癌的患者接受了全面检查，并采用TNM分类法进行了超声以及手术和病理分期。经直肠超声与病理结果相比的可靠性指标显示，T1-T2和T4期的敏感度为100%；T3期病变的敏感度为76%。各期的特异度在94%至100%之间。我们认为，经直肠超声是一种用于直肠癌分期的有用、精确且可靠的诊断工具。
