Chinese Ostomy Collaboration Group (COCG) Clinical Study -SITI Classification

Colorectal cancer is an important cancer worldwide, and its incidence is increasing year by year. A large proportion of patients may require diverting stoma or even permanent stoma after surgery. Some of these patients will have a variety of stoma-related complications, which seriously affect the quality of life of patients. At present, the mainstream postoperative complication classification is the traditional CD classification, which is suitable for the classification of most postoperative complications. However, due to the unique anatomical characteristics of patients with stoma, the current CD classification system may not be suitable for the classification of patients with stoma-related complications. Therefore, we plan to establish a registry database of colorectal cancer patients with stoma, explore the attribution and incidence of stoma-related complications, and propose a new improved classification system, the SITI classification, on the existing CD classification, for verification and promotion.
