Summary
Brief summary (as posted)
A retrospective cohort study, conducted nationwide（China） and across multiple centers, aimed to compare the surgical quality and short-term outcomes of R-NOSES （robotic natural orifice specimen extraction surgery）with R-TSES （robotic transabdominal specimen extraction surgery） for early-stage rectal cancer.
