Local pelvic perineal recurrence represents the most frequent site of failure following abdominoperineal resection (APR) for rectal cancer. Patients con be studied at this level by Computerized Tomography (CT) scan, Magnetic Resonance Imaging (MRI), suprapubic or, in women, endovaginal ultrasound (US). CT scan and MRI show sensitivity and specificity in excess, respectively, of 70 and 90%, but the high cost and the invasiveness of CT scan controindicate their frequent use. Suprapubic US has no value in terms of diagnostic accuracy, whereas endovaginal US shows a good specificity, but it is quite refused by the patients since the discomfort of the examination. 34 patients from the Rehabilitation Unit of Colostomy Patients at the University of Rome, "La Sapienza", have been blindly followed by transperineal US. The results have been compared with those obtained by CT scan or MRI. Specimens have been obtained of any suspicious mass by needle biopsy. The diagnostic accuracy of transperineal US has resulted comparable to CT scan and MRI. The authors also describe the morphology and US pattern of the pelvic hollow as demonstrated by transperineal US and the distinctive features of abnormality seen.
局部盆腔会阴复发是直肠癌腹会阴联合切除术(APR)后最常见的失败部位。在这一水平上,可通过计算机断层扫描(CT)、磁共振成像(MRI)、耻骨上超声检查,或在女性患者中通过经阴道超声检查(US)对患者进行研究。CT扫描和MRI的敏感性和特异性分别超过70%和90%,但CT扫描成本高且具有侵入性,因此不适合频繁使用。耻骨上超声检查在诊断准确性方面没有价值,而经阴道超声检查具有良好的特异性,但由于检查带来的不适,患者对此检查相当排斥。罗马大学“La Sapienza”结肠造口患者康复科的34例患者接受了经会阴超声检查的盲法随访。将结果与CT扫描或MRI检查结果进行了比较。通过针吸活检获取了任何可疑肿块的标本。经会阴超声检查的诊断准确性已被证明与CT扫描和MRI相当。作者还描述了经会阴超声检查所显示的盆腔凹陷的形态和超声特征,以及所见到的异常的独特特征。
