Knowledge-enhanced Digital Intervention to Prevent Low Anterior Resection Syndrome

"This study will be conducted in two stages, recruiting patients scheduled for low anterior resection and those scheduled for ostomy restoration after low anterior resection. The pilot stage study will recruit 20 subjects without randomization to evaluate the feasibility of the management program app, and the second stage study will be a parallel experimental-control study, recruiting approximately 300 research participants, 150 from each group.~Patients scheduled for ostomy repair after low anterior resection and low anterior resection are required to fill out a consent form the day before, and participants are randomly assigned to one of two groups in a 1:1 ratio: the experimental group and the control group. Both groups are randomly assigned to four surveys. The types are three quality of life assessment questionnaires (QOL (EORTC QLQ-C30, CR-29, EQ-5D-L)) and a questionnaire related to bowel symptoms (LARS). However, patients undergoing ostomy repair are excluded from the preoperati"

Subjects classified as control group will receive educational materials. One month and three months after surgery, a questionnaire related to bowel symptoms (LARS) will be administered by phone. The researcher will call the subjects and administer it according to the period. The results of the questionnaire related to bowel symptoms (LARS) administered by phone will be confirmed by the medical staff during outpatient treatment.
