Preservation versus non-preservation of left colic artery in sigmoid and rectal cancer surgery: A meta-analysis

In comparison with ligating the left colic artery, preserving the left colic artery seems to achieve comparable success with acceptable safety outcomes and we suggest to preserve the LCA in the sigmoid and rectal cancer surgeries. However, more multicenter randomized controlled trials are required to further evaluate the efficacy and safety of preserving the left colic artery in surgeries.
