Quality assessment of surgery for colorectal cancer: Where do we stand?

Table 1 Quality markers in rectal surgery for rectal cancer

Dissection	Margins	CVL
Mesorectal plane	Proximal margin	Tumor to tie length
Intramesorectal plane	Distal margin	IMA stump
Muscularis propria plane	CRM
Mesenteric area	Extramesorectal CRM

CRM: Circumferential resection margin; CVL: Central vascular ligation; IMA: Inferior mesenteric artery.

Table 2 Quality markers in colon surgery for colon cancer

Dissection	Margins	CVL
Mesocolic plane	Proximal margin	Tumor to tie length
Intramesocolic plane	Distal margin	IMA stump
Muscularis propria plane	Posterior CRM	ICA stump
Mesenteric area	Extramesocolic CRM	Middle colic stump

CRM: Circumferential resection margin; CVL: Central vascular ligation; ICA: Ileocolic artery; IMA: Inferior mesenteric artery.
