This topic is about someone who tried a new Hollister one-piece ostomy pouch and initially found it great. However, after a couple of weeks, they started experiencing a rash, discomfort, and even a leak. They suspect that their habit of filling the pouch with water and rinsing it every time they empty it might be causing these issues. They switched back to their previous appliance, the ConvaTec 22771, which resolved the skin and leakage problems, although they still wish ConvaTec would improve the outlet design and reduce the noise from the plastic.

Here are some insights and advice shared by others:

1. The person is curious if rinsing affects one-piece and two-piece systems differently. They use a one-piece system applied directly to the skin, with only stoma powder and a barrier wipe around the opening. They rinse several times a day with plain water, unlike a friend who uses soap for a more thorough clean.

2. Several members of the community also rinse their pouches, with one adding soap each time.

3. Some stoma nurses have advised against rinsing the entire pouch on a two-piece system. Water can seep between the pouch and flange, loosening the seal and causing leaks.

4. Nurses recommend rinsing only the tail or end spout of the Hollister two-piece drainable bag before folding and closing it.

5. A possible takeaway is that rinsing practices might need to be different for one-piece and two-piece systems to avoid compromising the seal.
