Clinically, the effect after anal preservation surgery for low rectal cancer is better, which can preserve the anus and maintain the patients’ defecation function.
Low rectal cancer anus-preserving surgery refers to rectal cancer whose tumor is located at 8cm of anal margin and the anal sphincter and anal raphe muscle are not invaded, adopting anus-preserving surgery, which can not only preserve the normal structure of the anus, but also help the patients to maintain the normal function of defecation, and the result is better.
With anal preservation surgery for low rectal cancer, the survival rate of patients is generally higher, the 5-year survival rate can reach 87%, and the recurrence rate is lower.
The higher the location of the tumor, the higher the possibility of anal preservation, while the lower the location of the tumor, the lower the possibility of anal preservation, and the postoperative recurrence rate will increase. However, with the progress of medicine, many ultra-low tumors can also be treated with anal preservation.
