Author contributions: Ni LT, Zhao R, Ye YR performed the data extraction; Ni LT, Zhao R performed the primary literature; Ouyang YM analyzed the data; Chen X designed the research study and revised the manuscript for important intellectual content; and all authors read and approved the final version. Ni LT and Zhao R contributed equally to this work. The reasons for designating Ni LT and Zhao R as co-first authors are threefold. Firstly, the research is a team collaboration, and the designation of co-first authors accurately reflects the equal contributions of the two individuals, especially in terms of primary literature writing and data collection. Secondly, the completion of the study requires different people to provide different assistance, and designating co-first authors can bring different perspectives to the study and enrich the content of the research. Thirdly, co-first authors can reflect their respective efforts and contributions, and better reflect the spirit of teamwork. In summary, we believe that designating Ni LT and Zhao R as co-first authors is suitable for our manuscript as it accurately reflects team spirit and equal contribution.

Abstract
BACKGROUND

Surgical site infection (SSI) is a common complication of colorectal surgery. Minimally invasive surgery notably reduces the incidence of SSI. This study aimed to compare the incidences of SSI after robot-assisted colorectal surgery (RACS) vs that after laparoscopic assisted colorectal surgery (LACS) and to analyze associated risk factors for SSI in minimally invasive colorectal surgery.

AIM

To compare the incidences of SSI after RACS and LACS, and to analyze the risk factors associated with SSI after minimally invasive colorectal surgery.

METHODS

Clinical data derived from patients who underwent minimally invasive colorectal surgery between October 2020 and October 2022 at the First Affiliated Hospital of Soochow University were collated. Differences in clinical characteristics and surgeryrelated information associated with RACS and LACS were compared, and possible risk factors for SSI were identified.

RESULTS

A total of 246 patients (112 LACS and 134 RACS) were included in the study. Fortythree (17.5%) developed SSI. The proportions of patients who developed SSI were similar in the two groups (17.9% vs 17.2%, P = 0.887). Diabetes mellitus, intraoperative blood loss ≥ 100 mL, and incision length were independent risk factors for SSI. Possible additional risk factors included neoadjuvant therapy, lesion site, and operation time.

CONCLUSION

There was no difference in SSI incidence in the RACS and LACS groups. Diabetes mellitus, intraoperative blood loss ≥ 100 mL, and incision length were independent risk factors for postoperative SSI.

Core Tip: The application of robotic surgery in colorectal surgery is becoming increasingly widespread. While it brings convenience of operation, it is still unclear whether it increases the risk of surgical site infection (SSI). The current study compared the incidences of SSI in robot-assisted colorectal surgery and laparoscopic-assisted colorectal surgery, and analyzed potential risk factors associated with SSI after minimally invasive colorectal surgery, to provide guidance for clinical practice.
