Selecting the right convexity fit can help prevent leakage, protect peristomal skin and improve wear time—key factors in maintaining patient comfort and confidence.
Latest evidence supports that depth and tension location are the strongest drivers of tension. Central tension supports stoma protrusion, while peripheral tension helps flatten irregular peristomal contours. Together, they shape how Esteem Body™ seals and protects skin.
Following the consensus guidance, we should always use the least amount of convexity necessary to protect skin and prevent complications.
New convexity guidance helps clinicians confidently match depth to anatomy, not default to extremes. Convexity selection should be based on a clinical assessment of the stoma and abdominal profile8
Consider your desired outcome.
Do you need to flatten the skin or protrude the stoma?
Define the tension location.
Or where the force must be applied.
Determine the depth needed.
This is the magnitude of the force applied.
Gentle flexibility provides comfortable, effective support at different depths while offering the least amount of convexity to achieve the desired clinical outcome.
Soft convexity has shown to be effective more broadly across a range of abdomen types, and the least amount of convexity (least pressure) possible should be used to avoid skin damage and complications.8
Soft convex is a more comfortable choice for many body types compared with rigid barriers.
Esteem Body™ convex solutions help clinicians achieve the right outcome with the least amount of convexity; tailored to real patient anatomy.
When anatomy requires more support, 7 mm is deep enough to achieve the outcome with the least amount of convexity.
