Abstract

Endoscopic ultrasonography (EUS) provides valuable information concerning the choice of operating methods for rectal cancer with a staging of local invasion and lymphnodal metastatic involvement. In our experience (1990-1992) EUS was performed in 21 cases of rectal adenocarcinoma and the results of preoperative staging were compared to the histopatological findings of the excised specimen. The depth of cancer invasion was correctly estimated in 76.2% of 21 cases. Metastatic lymphnodes were correctly detected in 8 cases of the 9 demonstrated histologically (88.8%); in 4 cases of 11 without lymphnodal metastatic involvement, EUS provided an overstaged evaluation with an overall accuracy of 75% (in 1 patient with local recurrence N wasn't correctly assessable because of previous lymphoadenectomy).
