About this trial
TME remains standard treatment for rectal cancer. Both Robotic TME and taTME are innovative surgical techniques with potential advantages in low rectal cancer. To date, no clinical studies have directly compared the conversion and complication rates between taTME and RTME in this population. Therefore, the investigators propose to conduct a prospective, randomized, parallel-controlled clinical trial comparing taTME with RTME for low rectal cancer, aiming to provide high-level evidence for surgical decision-making and benefit more patients.

Treatments tested in this trial
robotic surgery vs transanal total mesorectal excsion
Procedure/SurgeryThis study is designed to investigate the safety and superiority of transanal total mesorectal excision (taTME) in the treatment of rectal cancer compared with robot-assisted total mesorectal excision (rTME)
Treatment groups
Trial outcomes
Primary outcomes
Intraoperative Conversion Rate
During transanal total mesorectal excision (TaTME), if the procedure cannot be completed due to difficulty in transanal operation, conversion to open abdominal surgery is required to complete TME resection, allowing better operative access, organ preservation, and tumor clearance. During robot-assisted total mesorectal excision (rTME), if the transabdominal approach fails to achieve bowel transection or digestive reconstruction, conversion to transanal or open abdominal surgery is required to complete the procedure, ensuring operability, organ preservation, and tumor clearance.
Secondary outcomes
3-year disease-free survival (DFS)
3-Year DFS (Disease-Free Survival) refers to the proportion of patients who remain alive and free from any signs or recurrence of the disease for three years following surgical removal of the primary tumor.
3-Year OS
3-Year OS (Overall Survival) refers to the percentage of patients who remain alive for three years following a surgical procedure, regardless of the cause of death or the status of the disease. The survival time is typically calculated from the date of surgery to the date of death from any cause. Patients who are alive at the three-year mark-whether they are disease-free, have experienced a recurrence, or are receiving other treatments-are counted as survivors
operative time
Operative time refers to the total duration measured from the initial surgical incision to the completion of wound closure. It typically includes all intraoperative procedures, such as dissection, resection (e.g., tumor removal), reconstruction, hemostasis, and placement of drains or implants, but excludes anesthesia induction, positioning, prepping, draping, and recovery room time
