title: Computed tomography and endosonography in the preoperative staging of rectal carcinoma.
abstract: In 30 patients with rectal carcinoma the accuracy of computed tomography (CT) and endosonography (ES) was compared with the surgical specimen. Three cases were overstaged by ES and 4 cases were understaged by CT. The accuracy of ES was 84% and of CT only 76%. Both methods had advantages and limitations. An accurate staging of lymph node metastases was possible neither by ES nor by CT. - We advocate endosonography as the first imaging examination after proctoscopy. CT is recommended in endosonographic doubtful findings and in tight stenoses.
