The preservation of the left colic artery (LCA) during rectal cancer resection remains a topic of controversy, and there is a notable absence of robust evidence regarding the outcomes associated with LCA preservation. And the advantages of robotic-assisted laparoscopy (RAL) surgery in rectal resection remain uncertain. The objective of this study was to assess the influence of LCA preservation surgery and RAL surgery on intraoperative and postoperative complications of rectal cancer resection. Patients who underwent laparoscopic (LSC) or RAL with or without LCA preservation resection for rectal cancer between April 2020 and May 2023 were retrospectively assessed. The patients were categorized into two groups: low ligation (LL) which with preservation of LCA and high ligation (HL) which without preservation of LCA. A one-to-one propensity score-matched analysis was performed to decrease confounding. The primary outcome was operative findings, operative morbidity, and postoperative genitourinary function. A total of 612 patients were eligible for this study, and propensity score matching yielded 139 patients in each group. The blood loss of the LL group was significantly less than that of the HL group (54.42 ± 12.99 mL vs. 65.71 ± 7.37 mL, p<0.001). The urinary catheter withdrawal time in the LL group was significantly shorter than that in the HL group (4.87 ± 2.04 d vs. 6.06 ± 2.43d, p<0.001). Anastomotic leakage in the LL group was significantly lower than that in HL group (1...
