Total mesorectal excision has greatly reduced the local recurrence rate of rectal cancer after colorectal surgery. Transanal total mesorectal excision(TaTME) is potentially a suitable option for patients with middle and low rectal cancer. Robotic systems are expected to develop the advantages of TaTME to overcome the limitations of laparoscopic surgery. This study aimed to investigate the safety and feasibility of robotic assisted transanal total mesorectal excision in patients with rectal cancer.
TaTME is potentially a suitable option for patients with middle or low rectal cancer, especially for males with obesity and a narrow pelvis.The da Vinci robotic system (Intuitive Surgical, Sunnyvale, CA, USA) is expected to overcome the limitations of the laparoscopic transanal approach for rectal surgery. Da Vinci Si Surgical System or da Vinci Xi Surgical System would be used to performed Transanal total mesorectal excision. And the surgery would performed by two-team approach. This study aimed to investigate the safety and feasibility of robotic assisted transanal total mesorectal excision in patients with rectal cancer.
