Convexity Case Studies

Use these case studies to determine when and how to use convexity to improve your patient outcomes.


Creating a secure skin seal around the stoma relies heavily on pouching system fit. “Fit”' describes how the ostomy skin barrier is constructed to either conform to or reform the peristomal skin topography. This ensures that there is a smooth skin surface for secure pouching system adhesion, even if one had not existed before.

A common way to achieve this goal is by using a convex skin barrier. Convex skin barriers have been available for decades and are widely used by clinicians to manage patients with problem ostomies. Read the case studies below, in which stoma care nurses share their experiences with convexity. The case studies can provide another level of evidence to support your clinical practice and help you promote peristomal skin health.
