What Is the Correct Procedure for Evaluating the Quality of Surgery?
The evaluation of the quality of rectal cancer surgery by histopathologists is now routine practice in many countries. The importance of tumour clearance at the circumferential resection margin has been recognised since 1986. More recently, an assessment of the quality of the mesorectal dissection was introduced based on the presence and depth of defects into the mesorectal fascia. This was followed by a separate grading system for the dissection around the sphincters and levator ani muscles in abdominoperineal excisions. Individual specimen feedback to surgical teams using these grading systems has been shown to improve the quality of surgery over time, which should improve outcomes for patients with this disease.
