Abstract: 4K laparoscopy brings opportunities and challenges to the development of rectal surgery. 4K laparoscopy can truly provide the structure of abdominal and pelvic fascia, so that surgeons can see more subtle anatomical structure. The clear and real picture under 4K laparoscopic system can reduce visual fatigue of surgeons, which make the operation easier and safer. Radical resection of right colon cancer includes complete mesocolic excision and D 3 lymphadenectomy. Through 4K laparoscopic system, surgeons can easily observe the fascia structure of right mesocolon and its mesenteric bed, distinguish the vascular anatomical relationship at the mesenteric root, which make D 3 lymphadenectomy safer with dissection of lymph nodes completely. The authors comprehensively analyze the related research progress at home and abroad, and systematically elaborate the region of dissection and significance of 4K laparoscopic right hemicolectomy for right colon cancer.
