Sponsor decided to terminate study due to insufficient recruitment.

In this study, a novel ostomy ring device will be assessed for safety and efficacy in increasing the lifespan of ostomy pouching equipment.

In this crossover design trial, patients will be asked to first wear their normal ostomy pouching equipment for 28 days followed by 28 days with the OstoRing®. Patients may choose to continue using the OstoRing for an additional 19 days. Study visits will occur between each section of the trial and will involve a skin assessment and quality of life questionnaires. Additionally, over the course of the trial, participants will be asked to fill out a survey and take a picture of their stoma with ostomy pouching change.
