This study will include patients who have undergone colorectal cancer surgery and received either a colostomy or ileostomy, provided they are comfortable using digital devices like smartphones. Patients will be randomly assigned to either the intervention group, receiving stoma care through a smartphone application, or the conventional group, receiving standard outpatient-based care. The intervention group will use a mobile application where patients input their stoma condition, allowing healthcare professionals to monitor and manage their care. The app provides patients with information on diet, physical activity, stoma care, emotional support, and daily living needs. Both groups will be assessed for outcomes at the time of enrollment, and at 1 and 6 months. Outcome measures include stoma-related complications such as peristomal dermatitis, dehydration, acute renal failure, readmission due to stoma-related issues, and quality of life and emotional state assessments using EQ-5D-5L and Stoma Quality of Life questionnaires.
