Since there is no abstract available we provide the first paragraph.

Many surgeons have standardized the surgery for colon and rectal cancer including “high tie” of the inferior mesenteric artery. This strategy allows additional dissection of lymph nodes around the root of the inferior mesenteric artery leading to a true complete tumor (R0) resection. Depending on T-stage, the rate of these lymph nodes containing metastases may be substantial and thus a less radical lymphadenectomy increases the risk of nodal recurrence at the root of the inferior mesenteric artery. The reduced blood supply and increased risk of anastomosis can be overcome with standardized mobilization of splenic flexure in open or laparoscopic surgery. Another method is to dissect lymph nodes while preserving the inferior mesenteric artery and left colic artery.
