Summary
Brief summary (as posted)
ERUS-3D and CMI demonstrated good diagnostic accuracy in parietal staging of rectal extraperitoneal neoplasms, however with greater efficiency of the endoscopic method. The association of studies can improve diagnostic efficacy and influence the most appropriate approach.
