Expected outcomes for a correctly fitted ostomy prosthetic device include sustained, predictable wearing time, protection of the stoma from injury, and maintenance of peristomal skin integrity. To accomplish this, the pouching system must be properly sized and maintain continuous contact with the peristomal skin. Continuous contact is achieved when the faceplate provides a mirror image of the topography of the peristomal plane. Varying degrees of support and convexity of the faceplate are used to fit the unique characteristics of the patient's peristomal plane and stoma. Support can be absent, soft or firm. Convexity is some degree of outward curving of the faceplate. Characteristics of the stoma (i.e., flush, retracted, loop), peristomal plane (i.e., creases, hernia, scarring) and abdomen (i.e., flaccid, soft, or firm) may indicate the need for convexity. Potential problems include mucocutaneous separation, ischemia, laceration, erythema, ecchymosis, and pain if convexity is used inappropriately. Alternatives to convexity include the use of an ostomy belt or surgery. Ongoing, intermittent assessment of the prosthetic is essential to evaluate that the convexity and support have achieved the expected outcomes.
正确佩戴的造口修复装置的预期效果包括佩戴时间持续且可预测、保护造口免受损伤以及维持造口周围皮肤的完整性。要实现这一点，造口袋系统必须尺寸合适并与造口周围皮肤保持持续接触。当面板呈现造口周围平面地形的镜像时，就能实现持续接触。面板的不同程度的支撑和凸度用于适应患者造口周围平面和造口的独特特征。支撑可以不存在、柔软或坚硬。凸度是指面板有一定程度的向外弯曲。造口的特征（即平齐、内陷、袢状）、造口周围平面（即褶皱、疝气、瘢痕形成）和腹部（即松弛、柔软或坚硬）可能表明需要使用凸度。如果不恰当地使用凸度，可能会出现黏膜皮肤分离、局部缺血、撕裂、红斑、瘀斑和疼痛等问题。替代凸度的方法包括使用造口带或手术。对修复装置进行持续、间歇性评估对于评估凸度和支撑是否达到预期效果至关重要。
