Objective: To investigate the application of anal sphincter preserving in the treatment of anal sphincter low rectal cancer. Methods: On the basis of total mesorectal excision, the domestic disposable tubular stapler was used to preserve the anus external anal sphincter ulnar anus anastomosis in 32 patients with low rectal cancer for a follow-up of 12 to 36 months. Retrospective analysis of its radical, postoperative bowel function, surgical complications, local recurrence rate. Results: There was no residual incision, no incontinence and no anastomotic leakage in all the cases. There was no operative death in all the cases. The local recurrence rate was 9.4% (3/32). Conclusion: The preservation of anus external anal sphincter preserving anus surgery in low rectal cancer, follow the principle of tumor radical, can retain the normal anal defecation function, significantly improve the quality of life of these patients.
