D3 lymph node dissection with versus without left colic artery preservation in single-incision laparoscopic surgery for sigmoid and rectosigmoid cancer: A propensity score-matched analysis.

There were no significant differences in the short- and long-term outcomes of patients who underwent single-incision laparoscopic surgery with D3 lymphadenectomy with versus without LCA preservation. This suggests that LCA preservation is safe and feasible in single-incision laparoscopic surgery for sigmoid and rectosigmoid colon cancer.
