To evaluate the clinical value of total laparoscopic radical resection of colorectal cancer and high rectal cancer without abdominal auxiliary incision.

Thirty patients diagnosed as sigmoid colon cancer or high rectal cancer underwent laparoscopic surgery were randomly divided into control group and observation group. The patients in observation group were treated by total laparoscopy without abdominal incision, while the control group was treated by routine surgery with lower abdominal incision. The intro-operative indexes, postoperative short-term indexes and pathological results were compared.

There was no significant difference in the operation time or the amount of blood loss during the operation between the two groups (P>0.05). There was no significant difference in the incidence of postoperative complications or the cost of operation between the two groups (P>0.05). The time of hospitalization in the observation group was significantly shorter than that in the control group (P=0.003). There was no significant difference in the distance between the distal margin of the cutting edge or the number of lymph node dissection between the two groups (P>0.05).

Total laparoscopic radical resection of colon cancer and high rectal cancer without abdominal auxiliary incision is safe and effective, with less trauma and faster postoperative recovery, and does not increase the economic burden of patients.
