Abstract
Procedures of laparoscopic total mesorectal excision (TME) with electric hook for rectal cancer are described. Laparoscopy requires cooperation between the surgeon, first assistant surgeon and second assistant surgeon, in order to recognize the inferior mesenteric artery (IMA), the inferior mesenteric vein (IMV), the neurovascular bundle (NVB), and the fibrous tissues between the mesorectum and the surrounding tissues or organs. Some important organs, such as the autonomic nerves, left ureter, left gonadal vessels, and pancreas, should be avoided being injured. Comparing with ultrasound knife, the advantage of electric hook is obvious. Less smog will be produced if the electric hook is used within 2 seconds, and clearer dissectible layer will appear during the TME surgery with electric hook.
