Abstract:Objective：To evaluate the feasibility, safety and short-term outcome of laparoscopic-assisted surgery for colorectal cancer. Methods：From August 2001 to November 2004, laparoscopic resection of colorectal carcinoma were performed in 112 cases, including right hemicolectomy(n=23), left himicolectomy(n=7), radical resection of sigmoid cancer(n=15), Dixon procedure(n=49), and Miles procedure(n=18). Results：One hundred and five patients underwent laparoscopic resection successfully, 7 cases were converted to open surgery because of hemorrhage, obesity or adhesion with adjacent organ, 6 of which were left colon or rectal cancer. The mean operating time was (161.2±48.6)min, and the mean operative blood loss was 78.5 mL. There were 8 cases occurred postoperative complications, and no mortality during perioperative period. The length of upper and lower segment of resection for colonic cancer was (14.5±3.2)cm and (11.0±2.6)cm respectively. The length of upper and lower segment of resection for rectal cancer was (15.3±2.7)cm and (2.8±1.6)cm, respectively. The mean number of lymph nodes dissected was (8.2±4.6), and lymph node metastases were found in 49 cases. One hundred and seven cases(95.5%) were followed up for 8-44 months, of which, 7 cases had local recurrence and 6 cases had distant metastases. No case of trocar port tumor implantation was observed. Conclusions：Laparoscopic surgery for colorectal cancer is feasible and safe, can result in the same outcome as open radical surgery, and has the advantages of mini-invasive procedure.
