However, it is debatable whether it is better to preserve or remove the left colic artery (LCA). This study aimed to compare D3 lymphadenectomy with versus without LCA preservation in single\u2010incision laparoscopic surgery for sigmoid and rectosigmoid cancer.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 1138 patients underwent surgery for colorectal cancer between April 2011 and December 2018 at Fukui Prefectural Hospital.
