Summary
Brief summary (as posted)
Robotic rectal cancer resection with natural orifice extraction is a recently developed minimally invasive surgery for patients with rectal cancer. However, it's safety and feasibility remain undiscussed and controversial. This study reported the clinical outcomes and prognostic factors of robotic assisted rectal cancer resection alone vs. robotic rectal cancer resection with natural orifice extraction to discuss aforementioned question.
