Anterior rectal resection has become the primary surgical treatment for rectal cancer. However, studies have reported that up to 80%-90% of patients who undergo anterior rectal resection experience varying degrees of defecation dysfunction after surgery, such as frequent bowel movements, urgent bowel movements, and faecal incontinence, known as low anterior resection syndrome (LARS). This can lead to a decline in quality of life after surgery and even partial loss of social functioning.
