Background. Currently, the number of emergency operations ending with the removal of a colostomy, performed in a planned and emergency manner, continues to grow in the world. The presence of an uncomplicated lifelong colostomy already creates psychological difficulties for the patient, and a colostomy complicated by the presence of a parastomal hernia further reduces the quality of life of patients. The purpose of the study is to evaluate the results of treatment of patients who underwent colostomy in order to identify risk factors and predictors for the formation of parastomal hernias. Materials and methods. The analysis of the treatment of 107 patients of surgical departments of the Penza Regional Clinical Hospital named after N. N. Burdenko with various abdominal pathologies that required the removal of a colostomy in 2017-2020. Results. The results of treatment of patientswith stomas were evaluated on the basis of statistical methods of data processing. Conclusions. The analysis revealed the following risk factors for the formation of parastomal hernia: colorectal cancer as the cause of colostomy, history of constipation, removal of the colostomy through the external oblique muscle of the abdomen, smoking, suppuration of the wound in the postoperative period. A predictor of hernia formation is a body mass index of more than 32.1 (kg/m2).
