Summary

Brief Summary Background 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. Methods Participants 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.

Detailed description

The investigators retrospectively collected data from the medical records of participants who had rectal cancer at Northern Jiangsu People's Hospital, from April 2020 to May 2023. A total of 612 from 1164 cases were included in this study; in 462 cases, the LCA was preserved by LL intraoperatively (LL group), in which 202 cases underwent robotic-assisted laparoscopy (LL-RAL subgroup) and 260 cases underwent laparoscopy (LL-LSC subgroup). While in the remaining 150 cases, the LCA was not preserved by HL intraoperatively (HL group). in which 70 cases underwent robotic-assisted laparoscopy (HL-RAL subgroup) and 80 cases underwent laparoscopy (HL-LSC subgroup).
