[The anatomical characteristics and its applied significance of laparoscopic rectal surgery]

To realize the anatomical characteristics of laparoscopic rectum surgery and its clinical significance.

117 cases with benign and malignant diseases of rectum were operated by laparoscopic methods. The anatomy closely related with operation was analyzed.

The median operative time were 144 min. 4 cases were converted to open operations, so the converted rate was 1.7%. The blood loss in operation was rather little with an average of 126 ml. No instant or delayed injury of ureters, large bleeding in front of sacrum and other operation-related severe complications happened intra- and after operation. Dissecting only in one case disrupted the anterior-left wall of rectum.

Laparoscopic rectal surgery is clinically feasible. Mastering the anatomical characteristics of laparoscopic rectum surgery can make us reduce the operative mistakes and complications.
