Scoring the quality of total mesorectal excision for the prediction of cancer specific outcome

A three grade system for macroscopic evaluation of the resection plane is used to describe the quality of total mesorectal excision (TME). In several studies, two of the three grades have been combined when analysing the outcome. The aim of the study was to compare the predictive value of the three-graded with that of a two-graded TME score .status: publishe
