Safety and Efficacy Study of Single-port Robotic Versus Multi-port Robotic Radical Rectal Cancer Surgery: A Multi-center, Prospective, Open Label, Non-inferiority, Randomized Controlled Trial

Overview

This study is designed to evaluate the safety and efficacy of single-port robotic surgery compared to multi-port robotic surgery for rectal cancer.

Detailed description

Surgical robots were born in the 1980s and have the advantages of being precise, flexible, less invasive and remotely operable than traditional surgical methods. The single-port robot is a further extension of minimally invasive surgery by placing multiple instruments through a single incision. Most studies have reported on the perioperative outcomes of robotic versus conventional laparoscopic surgery in the treatment of colorectal cancer. However, there are limited data comparing the perioperative outcomes of single-port robotics and multi-port robotics in the treatment of colorectal cancer,especially in rectal cancer surgery. The purpose of this study is to evaluate the safety and efficacy of single-port robotic surgery compared to multi-port robotic surgery for rectal cancer.

Interventions

  • Procedure Single-port robotic surgery
    In this group, patients will be operated using a single-port surgical robot system. In the single-port configuration, a four-channel trocar shall be used. The surgical tools are steered through the curved access channels in the trocar to enter a patient's abdomen. The surgical procedure followed the principle of total mesorectal excision.
  • Procedure Multi-port robotic surgery
    In this group, patients will be operated using a multi-port surgical robot system. Surgical instruments enter the abdominal cavity through 4 separate trocars. The surgical procedure followed the principle of total mesorectal excision.

Primary outcome measures

  • Surgical success rate [Time frame: intraoperative]
Secondary outcome measures (12)
  • Operative time [Time frame: intraoperative]
  • Intraoperative blood loss [Time frame: intraoperative]
  • Incision length [Time frame: intraoperative]
  • Total incision length [Time frame: intraoperative]
  • Length of stay [Time frame: 1-30 days after surgery]
  • Postoperative recovery course [Time frame: 1-14 days after surgery]
  • Early morbidity rate [Time frame: 30 days after surgery]
  • Pain score [Time frame: 1-3 days after surgery]
  • Tumor size [Time frame: 14 days after surgery]
  • Incisal margin [Time frame: 14 days after surgery]
  • Lymph node detection [Time frame: 14 days after surgery]
  • Cosmetic effect [Time frame: 1 month, 6 months and 1 year after surgery]
