In plain words

What the trial is, and whether it could suit you

It is controversial that totally laparoscopic right hemicolectomy with transvaginal natural orifice specimen extraction (NOSES VIIIA) can provide non-inferior oncological outcomes compared to conventional laparoscopic surgery with mini-laparotomy in the treatment of right colon cancer. We aim to carry out a multicenter, open-lable, parallel, non-inferiority, phase III, randomized controlled clinical trial, which enrolls 356 female patients with cT1-3NxM0 right colon adenocarcinoma. They are randomly assigned to the experimental group (NOSES VIIIA) or the control group (laparoscopic surgery with mini-laparotomy) in a 1:1 ratio. Perioperative indicators, pathological results, quality of life and cosmetic evaluation will be compared between the two groups. Then, a three-year follow-up of these patients will provide evidence for long-term oncological outcomes of NOSES VIIIA.
