Extent of lymph node dissection and interpretation of technical standards for 4K laparoscopic colonic cancer surgery in China and Japan / 中华消化外科杂志

ABSTRACT

Colon cancer is one of the common digestive system tumors, and its incidence has an increased tendency. Comprehensive treatment based on surgery is still the current treatment. Although the laparoscopic technology of colorectal surgery in China has been rapidly developed in the past 30 years, there is no unified concept for the principles of colon cancer treatment, the scope of lymph node dissection is controversial, and the surgical approach is not unified. The author provides a detailed interpretation of the Chinese and Japanese laparoscopic colon cancer surgical dissection guidelines and technical standards based on Chinese Expert Consensus on Operation Standard of 4K Laparoscopic Surgery for Colorectal Cancer (2020 Edition), The Japanese Classification of Colorectal, Appendiceal and Anal Carcinoma (9th edition), The Guidelines for the Treatment of Colorectal Cancer (2019 edition) and Guideline for Operative Procedure of Laparoscopic Radical Resection of ColorectaI Cancer (2018 edition).
