Intrarectal ultrasonography is a new imaging method used in the preoperative staging of rectal cancer. Twenty five patients with proven rectal cancer were submitted to preoperative intrarectal ultrasonography; 24 were resected. Real time scanner with a linear probe of 5 MHz was employed. Five sonographic structures corresponding to the five histological layers were evidenced. Ultrasound T staging was compared to pathology, using UICC classification. In all but two cases pathology corresponded to ultrasound T staging (accuracy 92%). Perirectal nodal involvement was also investigated. It is concluded that intrarectal ultrasonography will play a definite role in the preoperative staging as well as in programming treatment of rectal carcinoma.
直肠内超声检查是一种用于直肠癌术前分期的新成像方法。25例经证实的直肠癌患者接受了术前直肠内超声检查；24例接受了手术切除。使用了带有5兆赫线性探头的实时扫描仪。发现了与五个组织学层次相对应的五个超声结构。采用国际抗癌联盟（UICC）分类法，将超声T分期与病理结果进行了比较。除两例外，病理结果均与超声T分期相符（准确率92%）。还对直肠周围淋巴结受累情况进行了研究。结论是，直肠内超声检查在直肠癌的术前分期以及治疗方案制定中将发挥明确作用。
