PREOPERATIVE STAGING OF RECTAL CANCER BY ENDORECTAL SONOGRAPHY
Mohamed Mahmoud Ali;
Abstract
The purpose of this study is to evaluate the efficacy of combining gray scale sonography with color-flow imaging and pulsed Doppler transrectal sonography in the staging of rectal carcmoma.
Endorectal sonography of the rectal wall has become an accepted technique for evaluating rectal wall masses and perirectal abnormalities (f-lu/oman FI-l, et al, 1992)
Improvement in transducer technology allow identification of individual rectal wall layers making endorectal sonography particularly suited for evaluating the extent of rectal wall involvement of both benign and malignant neoplasms.
While gray-scale findings during endorectal sonography may yield accurate information for tumour staging, overstaging and (less commonly) understaging can occur. Due to potential inaccuracies of local tumour staging with endorectal sonography, additional imaging studies (i.e. CT, MRI) are usually needed to confirm tumour beyond the confines of rectal wall, particularly in cases of perirectal fat invasion, perirectal lymphadenopathy, pelvic side wall extension and distant metastasis. Colour Doppler imaging during endorectal sonography has recently been performed during the preoperative evaluation of rectal wall masses (Alexander AA, et al, 1994).
Colour flow imaging and pulsed Doppler imaging are useful addition to gray-scale transrectal sonography in staging primary rectal carcinomas, the combination has most value when evaluating perirectal nodes.
