The applications of rectal endosonography (ES) in the preoperative staging and follow-up of patients with rectal cancer have been investigated. Endosonography is an accurate method of staging local invasion (93%) preoperatively and is superior to digital examination (58%) and computed tomography (CT) (74%). In addition, ES can predict mesorectal lymph node involvement with an accuracy of 83% which compares favourably with CT (57%). Extrarectal, locally recurrent cancer can be detected using ES and established recurrence assessed more objectively.
直肠内超声检查(ES)在直肠癌患者术前分期及随访中的应用已得到研究。超声检查是术前准确判断局部侵犯情况的方法(准确率93%),优于直肠指检(58%)和计算机断层扫描(CT)(74%)。此外,ES预测直肠系膜淋巴结受累的准确率为83%,优于CT(57%)。使用ES可检测直肠外局部复发性癌,并能更客观地评估确诊的复发情况。
