Enterostomy-related complications are common in abdominal surgery. The incidence enterostomy-related complications varies according to the type and location of stoma, surgical procedure, and patient characteristics. Currently, there are no uniform criteria wopldwide for the classification of enterostomy complications. Previous classification of enterostomy-related complications were based on time of occurrence, clinical manifestations, or anatomical changes, etc., lacking uniformity and reproducibility. The concept and diagnostic criteria of complications are not yet clearly defined; and it is difficult to accurately determine the relationship between their severity, intervention, and medical cost. Moreover, surgeons and enterostomal therapists differ significantly in their concerns, cognition, and management principles for stoma-related complications. Therefore,the Chinese Ostomy Collaboration Group (COCG), together with the Wound, Ostomy, and Continence Nursing Committee of Chinese Nursing Association, the Colon and Rectal Surgeon Committee of Surgeon Branch of Chinese Medical Doctor Association, the Committee of Colorectal Cancer of Chinese Anti-Cancer Association, and the Colorectal Surgery Group of Surgery Branch of the Chinese Medical Association, jointly drafted the criteria for the classification and grading of enterostomy complications. We hope this criteria will facilitate prospective data collection, clinical diagnosis, treatment, medical training and education.
