Robot assisted versus laparoscopic surgery for rectal cancer a systematic review and meta analysis of randomized controlled trials.DOI 10.1007s00464 026 11842 z

Surgery is one of the main treatments for rectal cancer. Many patients today undergo minimally invasive surgery, which can be done using either laparoscopic techniques or robot-assisted systems.
Laparoscopic surgery uses small instruments and a camera inserted through tiny incisions. It works well for many patients, but rectal surgery can be technically challenging because the pelvis is a narrow space.
Researchers recently reviewed 12 clinical trials including more than 3,200 patients to compare robotic surgery with laparoscopic surgery for rectal cancer.
The study found that robot-assisted surgery reduced the chances of needing to switch to open surgery during the operation. Conversion to open surgery sometimes happens when surgeons face technical difficulties, so lowering this risk can improve the surgical process.
Patients undergoing robotic surgery also experienced slightly less blood loss during the procedure.
Importantly, the two approaches showed similar results in cancer control and safety. There were no major differences in surgical margins, complication rates, or length of hospital stay.
One difference was that robotic surgery usually took longer to perform compared with laparoscopic surgery.
Overall, the findings suggest that robot-assisted surgery is a safe and effective option for rectal cancer treatment. It may offer technical advantages for surgeons and reduce the need for open surgery, while maintaining similar cancer outcomes.
Patients considering rectal cancer surgery can discuss with their healthcare team which surgical approach may be best for their individual situation.
