Abstract
Advancements in surgical techniques and equipment, combined with the increasing use of preoperative radiation, have made sphincter-saving procedures increasingly available to patients with rectal cancer. The accurate preoperative local staging of rectal cancer, including tumor depth penetration and regional lymph node metastases, is essential in determining the most appropriate therapeutic option available and provides valuable information on prognosis in patients with rectal cancer. Although several imaging modalities such as computed tomography and magnetic resonance imaging are available for the local staging of rectal tumors, endoscopic rectal ultrasound remains the modality of choice. It provides accurate assessment of tumor penetration into the rectal wall and information on regional lymph node staging in the majority of patients. This article will review the current modalities used for the preoperative staging of patients with rectal cancer, with emphasis on the use of endorectal ultrasound.
