Risk factors of anastomotic leakage after robotic surgery for low and mid rectal cancer

Objective: To investigate the risk factors associated with anastomotic leakage after robotic surgery in mid-low rectal cancer. Methods: A retrospective case-control study method was conducted. Inclusion criteria: (1) 18 to 80 years old; (2) pathologically confirmed rectal cancer; (3) distance /=180 minutes (OR=2.04, 95%CI: 1.03 to 3.99, P=0.040), distance
