Abstract: Anal-preserving surgery for low-lying, especially ultra-low-lying rectal cancer is a clinical difficulty, which generally means that the distance between the cancer and the anal verge is less than 7 cm or 5 cm. For such patients, the treatment goal is not only to cure the tumor, but also to consider how to preserve the patient’s urinary and sexual functions, anal sphincter and ensure the patient’s post-operative quality of life as much as possible. This is a common goal pursued by doctors and patients. This article reviews the anus-preserving surgical methods for low and ultra-low rectal cancer.
