title: [Results of endoscopic ultrasonography in the preoperative assessment of rectal cancer].
abstract: Endoscopic transrectal ultrasonography is performed with an ultrasonic transducer (7.5 MHz or 12 MHz) in the tip of a side viewing endoscope. Its accuracy to assess the depth of rectal cancer invasion was prospectively studied in 27 patients. The ultrasonic examination was correct in 23 cases; in 4 cases, the stricturing tumour could not be passed by the probe. The depth of invasion was correctly appreciated in 24 of the 27 cases (accuracy of 89%). The 6 superficial lesions were all correctly detected with endoscopic transrectal ultrasonography. Therefore, endoscopic transrectal ultrasonography appears to be a very promising method in the pretherapeutic staging of rectal cancer.
