Preoperative stoma site marking: a simple practice to reduce stoma-related complications.

BACKGROUND: To evaluate the incidence and identify the risk factors of stoma-related complications in a consecutive series of patients treated at a single institution. METHODS: For this retrospective analysis, the medical records of patients followed up at the stoma care centre of our institution over the last 16 years were reviewed. The primary end point was the incidence of stoma-related complications. Risk factors were tested using univariate and multivariate Cox proportional hazards models. RESULTS: Of a total of 1076 patients, 604 received a colostomy and 472 an ileostomy. In all, 1055 stoma-related complications were recorded in 797 patients. Univariate analysis identified the following risk factors for stoma-related complications: male sex (p = 0.032), emergency surgery (p = 0.010), open surgery (p < 0.001), and ileostomy creation (p = 0.004). Preoperative stoma site marking was noted to play a protective role (hazard ratio 0.739; 95% confidence interval 0.576-0.947; p = 0.017). Multivariate analysis confirmed male sex and ileostomy creation as risk factors (p = 0.030 and p = 0.013, respectively) and preoperative stoma site marking as an independent protective factor (p = 0.001). CONCLUSIONS: Stoma-related complications are quite common, especially when an ileostomy is present. Preoperative stoma site marking was noted to play a highly protective role not only in reducing the complication rate but also in improving the patients' quality of life.

A proposal for classifying peristomal skin disorders: results of a multicenter observational study.

The challenges of caring for abdominal ostomy disorders have grown over the years. Because the literature shows no evidence of a tool to classify peristomal skin disorders, a study group comprised of seven enterostomal therapy nurses and four surgeons sought to provide an objective, reproducible, standardized classification instrument. A prospective, observational study was conducted among eight ostomy centers across Italy. The 339 patient participants (272 men, 67 women, average age 63 [25 to 85] years) were divided into two groups according to onset of complications (less than or greater than 1 year); 800 digital photographs were taken to enhance observation and blood samples were drawn for additional data. From the data obtained, a classification scheme was created and subsequently tested using four non-study group experts. The resulting instrument facilitated lesion interpretation and detection, including topography. Thus far, this is the first validated classification attempt not based on assessments of lesions attributable to entirely different etiopathogenetic factors. Further research to refine the tool and to correlate the additional data obtained from blood samples with the classification system is underway.
