Low anterior resection syndrome refers to changes in bowel habits such as frequent defecation, urgent defecation, and fecal incontinence, which result in decreased bowel function. It occurs very commonly after surgery for colorectal cancer, especially rectal cancer, and symptoms appear severely immediately after surgery, followed by a recovery process. It is known that symptoms improve significantly after one year of surgery, but in some patients, symptoms persist, which significantly affects the quality of life and causes social problems. There is no established treatment method for low anterior resection syndrome, and accurate evaluation and customized treatment are required according to the patient's surgical or radiotherapy treatment content and symptoms. It is also important to monitor the change in symptoms during the treatment process, and a customized step-by-step treatment strategy for such patients is required. However, such a customized step-by-step treatment strategy for such patients is very complex, and there are no clear guidelines to date, and the research design for some clinical trials has been recently reported. The purpose of this study was to develop an app-based Patient-Reported Outcome (PRO) standardized questionnaire for patients after rectal cancer surgery to systematically collect and monitor symptom information, establish a multidisciplinary management plan tailored to patients, and provide education and treatment to improve the quality of life of rectal cancer survivors. A management program utilizing a research device (app) can reduce the incidence of Major LARS after rectal cancer surgery compared to standard treatment.
