Transanal Total Mesorectal Excision vs Robotic Total Mesorectal Excision

Condition(s) studied

Investigational drug(s) / intervention(s)

robotic surgery vs transanal total mesorectal excsion: This 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)

Study summary

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.

Eligibility

Primary outcome measure(s)

• Intraoperative Conversion Rate — at the end of operation
  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.
