Anastomotic leakage has been commonly regarded as one of the toughing postoperative complications in laparoscopic mid/low rectal cancer surgery, attenuating the short-term clinical benefits. The left colic artery (LCA) has been routinely central-ligated in dissection process to guarantee the oncological effects, which may potentially attribute to the postoperative ischemia-induced anastomotic leakage in the patients with left-colic vessel variation, e.g. bypass or absent of Riolan arch. However, no specific study focuses on the surgical benefits of LCA preservation compares to conventional ones. Herein, we conduct a single center randomized controlled trial, demonstrating that LCA-preserving technique shows significant reduction rate of postoperative leakage as well as overall complications comparing to the traditional central-ligation group. No difference in survival rate and recurrence in short term is found between the two groups. The LCA-preserving strategy is proven to be repeatedly safe and feasible, potentially reduce the risk of anastomotic leakage with comparable short-term outcomes. Further investigation is required for both the oncological safety and long-term prognosis for this innovative technique.
