皮肤病是造口患者的常见问题，导致超过三分之一的造口护士就诊。刺激性反应，特别是刺激性接触性皮炎，是最常见的，占> 50%的问题，在一些study.Objectives报告我们的经验，斑贴试验peristomal dermatitis.Methods所有的病人都确定了从我们的数据库的皮肤造口诊所。结果在联合门诊共850例造口患者中，149例患者进行了斑贴试验。只有7名患者（4.7%）有阳性反应的电流，证明相关性，其中没有一个是有关的造口器具本身的成分。大多数相关的过敏原是防腐剂和fragments.Conclusions过敏性接触性皮炎和刺激性接触性皮炎的症状和临床表现是相似的，在封闭的造口周围环境，因此很难区分单独的临床理由。尽管皮肤持续暴露于清洁剂、药物、其他附件和造口袋系统本身的组分，但过敏是造口周围皮炎的相对不常见的原因。
Background Skin disorders are a common problem for ostomates, resulting in more than a third of visits to a stoma nurse. Irritant reactions, particularly irritant contact dermatitis, are the most frequently seen, accounting for > 50% of problems in some studies.Objectives To report our experience in patch testing for peristomal dermatitis.Methods All patients were identified from our database of the skin-stoma clinic. Patch testing to various chemicals was performed and results analysed.Results From a total of 850 stoma patients in the combined clinic, 149 patients were patch tested. Only seven patients (4.7%) had positive reactions of current, proven relevance, none of which was related to constituents of the stoma appliances themselves. Most of the relevant allergens were preservatives and fragrances.Conclusions The symptoms and clinical appearances of allergic contact dermatitis and irritant contact dermatitis are similar in the occluded peristomal environment and are therefore difficult to distinguish on clinical grounds alone. Allergy is a relatively infrequent cause of peristomal dermatitis despite the continual exposure of skin to the components of cleansers, medicaments, other accessories and the stoma bag systems themselves.
