Colon cancer is one of the leading public health problems in the world today. The frequency of the disease is increasing rapidly, and prevention is possible with tests and examinations that allow the disease to be detected at an early stage, although the diagnosis of most patients is made only after the appearance of the first symptoms. The choice of treatment depends on the type, localization and advanced stage of the malignant process, and most often includes surgical treatment with the use of chemotherapy or a combination of chemotherapy and radiation. Intestinal stoma (colostomy) is an artificially created opening after surgery (resection) of a part of the large intestine that was performed on the front abdominal wall and has the function of a rectum. The fundamental task of creating a colostomy is to maintain the function of the digestive tract. It can be temporary or permanent. When performing a colostomy, proper health care is important because otherwise numerous complications can occur. In addition to the doctor, nurses and stoma therapists who educate the patient are of great importance for the recovery, but also the quality of life of people with a colostomy. Assessment of the quality of life is part of the evaluation of rehabilitation and therapeutic procedures. Quality of life implies total well-being, which is influenced by objective indicators and subjective perception of people, and evaluation of emotional, physical, social and material well-being. In addition to the medical staff, the family, which helps the patient in all aspects of recovery and further life with a colostomy, has a significant impact on the quality of life of a person with a colostomy.
