An MRI-based Assessment of Standard and Extralevator Abdominoperineal Excision Specimens: Time for a Patient Tailored Approach?

Background The extralevator abdominoperineal excision (ELAPE) has been proposed as oncologically superior to standard abdominoperineal excision (SAPE). However, little is known regarding comparative margins achieved in ELAPE and SAPE. The purpose of this study was to compare patterns of tissue removal between these two groups that can aid patient selection.
