Objective  To evaluate the feasibility, safety, radicality, and short-term and mid-term clinical outcomes of laparoscopic total mesorectal excision (TME) in comparison with open procedure for the middle-lower rectal cancer.
Methods  From October 2005 to October 2008, 52 patients with middle-lower rectal cancer received laparoscopic TME (Dixon’operation) without preventive stoma, while 46 patients underwent conventional open TME (Dixon’operation) without preventive stoma. The operative procedures, clinicopathological data, and short-term and mid-term outcomes were collected and compared between the two groups.
Results  The other patients were successful in both groups in addition to 2 (3.8%) patients were converted to open procedure in laparoscopic TME group. There was no perioperative death in both groups. The intraoperative blood loss, the time for bowel movement retrieval (first flatus), and the incision healing in laparoscopic TME group were better than that in open TME group (P<0.05). No significant differences were observed between two groups in anastomotic leakage and pulmonary infection (P>0.05). Comparison of specimen, no significant differences were observed between two groups in negative distal margin and circumferential resection margin, number of lymph nodes resected, distance of distal resection margin to the tumor (P>0.05). No significant differences were observed between two groups in cancer-related death, local recurrence, distant metastasis, and 3-year survival rate (P>0.05).
Conclusions  Laparoscopic TME for middle-low rectal cancer is a safe, feasible, and minimally invasive technique, and can achieve satisfactory oncological outcome, which provides similar short-term and mid-term outcome compared with the traditional open procedure.
