Rectal cancer patients with postoperative altered bowel function have poorer quality of life than colon rectal cancer patients with it. The altered bowel function symptoms were named low anterior resection syndrome. Mechanisms of these symptoms associated with removing rectum and receptors on its internal wall, creating neorectum, and destroying pelvic neuro-plexus by analsaving surgery. Due to the low anterior resection syndrome, patients suffered from physical, psychological and social impacts on quality of life. Three options are used to treat low anterior resection syndrome, including self-care strategies, clinician-initiated interventions, and creating a permanent stoma. The self-care strategies contain diet modification, lifestyle changes, and spiritual sublimation. The clinician-initiated interventions include prescribed medication, trans-anal irrigation, pelvic floor rehabilitation, neuromodulation, and so on. Creating a permanent stoma is the eventual choice due to anastomotic restriction. Altered bowel function may follow postoperative rectal cancer patients for whole life; however, flexibly using these care strategies may help them adjust.
