Objective: To investigate the effect of 3D laparoscopic natural orifice specimen extraction surgery as rectal cancer treatment. Methods: The study was carried out in Shaanxi Provincial People’s Hospital from July 2021 to July 2022. 80 rectal cancer patients were selected and divided into two groups which are the experimental group and control group. The experimental group was given 3D laparoscopic surgery while the control group was given 2D laparoscopic surgery. The results were compared and analysed. Results: The patients in the experimental group had shorter operative and evacuation times, less intraoperative bleeding, and a lower rate of complications. Conclusion: The clinical application of 3D laparoscopic radical surgery for rectal cancer via natural lumen extraction is more effective, which can promote patients' recovery and reduce the incidence of adverse events.
