The Minimum Length of Colonic Segment to be Removed for Adequate Lymph Node Dissection in Colorectal Cancer

ConclusionThe minimum length of bowel segment that needs to be removed in order to dissect 12 lymph nodes varies depending on the operation type, being 21 cm for a conventional right hemicolectomy and as high as 31 cm for a laparoscopic right hemicolectomy. The removal of a 16-cm bowel segment will suffice in a laparoscopic left hemicolectomy, while a low anterior resection requires a minimum 24-cm bowel segment to be removed.
