Objective: To investigate the best therapeutic technique for preserving anal sphincter function in patients with low rectal cancer. Methods: Abdominal and anal dentate line resection of the lower rectal cancer line sigmoid colon and anal canal line of anastomosis 2 2 cases. Results: There was no operative death in the whole group, no anastomotic leakage and anastomotic stricture. The patients were followed up for 11 months to 5 years with an average follow-up of 3 years and 1 month. After 10 to 12 weeks on the exhaust and dry stool control well, no stool incontinence. Three Dukes C1 patients died of distant metastases at 14, 18 months and 23 months after operation, with no local recurrence. Conclusion: According to the clinical staging and tumor biological behavior of rectal cancer surgery indications. Transabdominal and anterior teeth combined with radical resection of the lower rectal cancer line sigmoid colon and anal canal dentate line anastomosis is a good anal sphincter
