Abstract    Based on the concepts of complete mesocolon excision (CME) and D3 lymphadenectomy，the surgical scope of laparoscopic right hemicolectomy has formed a consensus，but controversy still exists in some details. In terms of the extent of intestinal resection，although the “10+5” principle has been widely used in clinical practice，there are still differences in the extent of intestinal resection when performing CME and D3 lymphadenectomy. For hepatic flexure and right transverse colon tumors，the feasibility of performing laparoscopic ileocecal-sparing right hemicolectomy (LISH) still needs to be demonstrated. Regarding the extent of lymph node dissection，there are still different views on the medial boundary of D3 lymphadenectomy，and the available evidence suggests that laparoscopic D3 lymphadenectomy along the left side of the superior mesenteric artery has some clinical value. For hepatic flexure and right transverse colon tumors，whether to routinely perform infrapyloric and gastroepiploic lymph nodes (IGLN) dissection is still inconclusive. Currently，Chinese scholars have conducted a series of high-quality clinical studies to investigate the above controversial issues.
