Abstract: Objective : To investigate the clinical value of anus-preserved surgery with super-low anastomosis for pa-tients with lower rectal cancer. Methods : We performed anus-preserved surgery with super-low anastomosis in 91 patients with low rectal cancer 2-4 cm from the dentation line. We divided these patients into three groups according to the distance between the anastomotic stoma and the dentation line: dentation line group, the 0-1 cm group, and the 1-2 cm group. The clinical outcome was compared among the three groups. Results: No patients died of surgery in all groups. The 1-, 3-, and 5- year survival rates were 97.8%, 81.4%, and 71.2%, respectively. No significant difference was found in the recurrence rate and complications among the three groups. The rate of good to fairish anal function was 77.8% in the dentation line group, 90.3% in the 0-1 cm group, and 94.3% in the 1-2 cm group. Conclusion : The anus-preserved surgery with super low anastomosis is safe and feasible for patients with low rectal cancer.
