How Can We Identify Mesorectal Fascia Involvement?

  • Regina G. H. Beets-Tan


The circumferential resection margin (CRM) is the lateral or radial resection margin created by the surgeon at the total mesorectal excision. A positive CRM is defined as a closest distance of 1 mm or less between tumor and resection margin, as this represents the optimal prognostic cutoff point. The importance as a prognostic factor and as a parameter of surgical quality has been recognized and confirmed in the past 20 years [1]. Because the ideal plane of resection in a total mesorectal excision is just outside the mesorectal fascia, a relevant question in rectal cancer surgery which is addressed in this chapter is “How can we identify mesorectal fascia involvement?”
