title: Endoscopic ultrasound in the pre-operative staging of rectal carcinoma.
abstract: Endoscopic ultrasound (EUS) was performed prospectively to stage 45 patients with rectal cancer. Patients were staged utilizing the TNM staging system. All patients subsequently underwent surgical resection with independent histopathologic staging. Depth of invasion was accurately predicted in 40 of 45 patients (89%). Presence or absence of lymph node metastasis was correctly determined in 34 of 45 patients (79%). EUS is an accurate method for local staging of rectal cancer.
