Risk factors for peristomal skin disorders associated with temporary ileostomy construction.

PURPOSE Skin disorders are the most common stoma-related complications after temporary diverting loop ileostomy with proctectomy. The aim of the present study was to investigate risk factors for skin disorders associated with temporary ileostomy construction. METHODS A total of 185 consecutive patients who underwent curative proctectomy with temporary diverting loop ileostomy for rectal malignancies at a single comprehensive cancer center between 2013 and 2018 were collected and analyzed. RESULTS The most frequent stoma-related complications were skin disorders (n = 62, 33.5%), followed by mucocutaneous separation (n = 38, 20.5%) and high-output stoma (n = 34, 18.4%). Patients with skin disorders had a higher median body mass index (BMI; 22.4 vs. 21.3 kg/m2, P = 0.002) and lower stoma height (16 vs. 20 mm, P < 0.001) than those without skin disorders. According to a multivariable logistic regression analysis, independent predictors of skin disorders included overweight (median BMI ≥ 25 kg/m2 [odds ratio = 3.6, 95% confidence interval: 1.5-8.6], P = 0.004) and lower stomal height (median stoma height < 20 mm [odds ratio = 3.2, 95% confidence interval: 1.6-6.3], P < 0.001). CONCLUSION Overweight and lower stoma height are correlated with the presence of skin disorders. Construction of a well-elevated stoma can reduce skin disorders associated with temporary ileostomy construction.
