Abstract:Objective： To explore the feasibility and value of laparoscopic-assisted surgery(LAS) for colorectal cancer. Methods：The clinical data of 51 cases of LAS for colorectal cancer were reviewed retrospectively. Of them, 3 cases were converted to open operation, and in 48 cases LAS for colorectal cancer was completed. Among them,9 cases underwent right hemicolectomy,8 cases left hemicolectomy,14 cases sigmoid resection,9 cases rectal anterior resection, and 6 cases Miles operation. Results：No intra-operative deaths occurred. The average operation time was 195（150-320）min with 120（40-300）mL average blood loss.The average number of lymph nodes excised was 8（2-26）.The time of bowel function recovery was 20-72h after operation.The average hospital stay after operation was 8（7-10）d.No major intra-operative blood loss nor postoperative complications were observed.The follow-up time was from 3-54months for 45(88.2%) patients. Two cases with Ducke′s C rectal cancer died,one died of liver metastasis 17 months after operation, and the another died of diffuse peritoneal metastasis 19 months after operation. There was no trocar port tumor metastasis and no local tumor recurrence at the small abdominal incision. Conclusions：LAS of colorectal cancer is technically feasible and has advantages such as less surgical trauma,less bleeding and quick recovery. It is a mini-invasive, safe and efficient treatment for colorectal cancer.
