Decrease the potential risk of stoma leakage 

Convex ostomy bags - a solution for your patients?

Stoma complications can occur within one month after surgery but also at a later stage.[1] Some of the contributing factors may be the stoma placement, its characteristics, fistula formation or a high liquid output.[1] When any of these obstacles arise, effluents may irritate the peristomal skin and even seep under the stoma wafer.[2] As a result, the adhesion of the device can be compromised, and the surrounding area may also be irritated.[3]

If your patient suffers from stoma leakage, a convex stoma appliance may solve the issue. You can determine whether it is suitable by assessing the type of stoma and the patient’s abdominal contours.

When should you suggest a convex stoma system?
