Introduction. A stoma formation is a frequently performed procedure in patients undergoing colorectal surgery. Although stoma formation is a simple process, it should be performed with caution. The aim of this study was to attract physicians’ attention to this rare disease and also to identify the surgical and medical treatment options for peristomal necrotizing fasciitis as a rare complication. Materials and Methods. Risk factors including age, sex, additional diseases, previous surgical procedures, source of infection, physical findings, and vital signs of 14 patients with peristomal necrotizing fasciitis over a period of 10 years from 2005 to 2015 were retrospectively evaluated. Results. Of the 14 patients, 9 were men and 5 were women. The average age was 63.28 years (range, 45–85 years). Risk factors were also observed: diabetes mellitus, 4 (28.57%); obesity, 3 (21.42%); alcoholism, 1 (7.14%); and malignancy, 10 (71.42%). Prophylactic antibiotic treatment was given to all patients, and they all underwent debridement and stoma replacement. Conclusion. Peristomal necrotizing fasciitis is an urgent and mortal disease. Risk factors, physical findings, and infection sources should be determined, and treatment modalities should be applied immediately. Medical treatment and surgical options should be performed, and vacuum devices should also be considered when treating this complication.
