For removed specimens in surgical treatment
1) Unfold the extracted sample in vivo and fix it on a plate with a pin. Mark the stump at the blood vessel and the junction with the marginal artery.
2) The lymph nodes are searched while clarifying the dominant blood vessels and the marginal arteries, and pathological diagnosis based on Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma is performed.
3) Classify the lymph nodes according to the definition, including the presence of the accessory middle colon artery.
