Objective To observe the clinical effect of preservation of the left colonic artery (LCA)and superior rectal artery(SRA) in laparoscopic radical resection of sigmoid cancer in elderly patients.

Methods The clinical data of 320 patients with sigmoid colon carcinoma undergoing laparoscopic radical resection were retrospectively analyzed. A total of 129 patients who retained LCA and SRA were included in experimental group, and 191 patients who did not retain LCA and SRA were included in control group. The intraoperative and postoperative conditions of the two groups were compared.

Results The experimental group underwent no prophylactic ileostomy, and 9 cases in the control group received prophylactic ileostomy, a significant difference was found in two groups(P < 0.05). Operation time was significantly longer in the experimental group than that in the control group (P < 0.05). No significant differences in terms of total number of lymph node dissection and the number of lymph node(No. 253) dissection, intraoperative blood loss, postoperative anastomotic bleeding, incidence of anastomotic leakage, recovery time of bowel sound, postoperative exhaust time and length of hospital stay were found between the two groups(P > 0.05).

Conclusion Preservation of LCA and SRA in laparoscopic radical resection of sigmoid cancer in elderly patients can reduce preventive terminal ileum stoma and it is safe and feasible in technology.
