Core Tip
Core Tip: Anterior resection syndrome remains one of the most challenging functional complications after sphincter-preserving surgery for low rectal cancer, substantially affecting patients' quality of life. This study demonstrates that combined magnetic-electrical biofeedback therapy significantly improves bowel function, anal sphincter function, anorectal physiological parameters, and patient-reported bowel function compared with conventional rehabilitation alone.
