Description
This data item records the results of a macroscopic evaluation of the mesorectum from a total mesorectal excision (TME)


Rationale
Numerous studies have demonstrated the total mesorectal excision (TME) improves local recurrence rates and the corresponding survival by as much as 20%. Macroscopic pathologic assessment of the completeness of the mesorectum, scored as complete, partially complete, or incomplete, accurately predicts both local recurrence and distant metastasis.
