Trial of Robotic Versus Laparoscopic-assisted Radical Resection for Rectal Cancer (TRVL)
Rectal Neoplasms
About this trial
This is an interventional treatment trial for Rectal Neoplasms focused on measuring robot-assisted total mesorectal excision(RTME), laparoscopic total mesorectal excision(LTME), urinary function, sexual function, sphincter- preservation, low rectal cancer

Robot-assisted total mesorectal excision
Laparoscopic total mesorectal excision
Robot-assisted total mesorectal excision (RTME) for rectal cancer. Two different RTME procedures were chose to personalized patients. Generally, when the tumor located within 5-15cm from the anal verge, low anterior resection (LAR) was employed, and tumor located below 5cm, abdominoperineal resection (APR) was applied usually.
Traditional laparoscopic total mesorectal excision (LTME) for rectal cancer was performed. The Urinary, sexual function and sphincter- preservation outcomes were evaluated.
