This topic is about dealing with recurring leaks in Coloplast 15521 one-piece ileostomy pouches. The person experiencing these issues has an ileostomy with mostly watery output and finds that leaks happen intermittently at the right edge of the pouch, about an inch below the visible flange. They have tried various methods to prevent these leaks but are still facing problems. They are unsure if the issue is due to user error or a manufacturing defect and are seeking advice from others before contacting the manufacturer.

Here are some helpful suggestions and insights:

1. If the barrier is intact and the leak is coming from the pouch wall or seam, consider reaching out to Coloplast with the lot numbers of the affected pouches. They might offer replacements or investigate a potential production flaw.

2. Check if all the faulty pouches came from the same production run. Identifying a pattern could help confirm if it's a manufacturing issue.

3. Try using ostomy adhesive tape around the flange for added security, especially during the night.

4. Ensure your skin is completely dry and evenly coated with any adhesive wipe before applying the pouch. This helps create a solid seal.

5. Make it a habit to empty the pouch before it becomes too heavy or full. Overfilling can increase internal pressure, leading to small leaks or even blow-outs.

6. For the drainable outlet, ensure the tail is free of debris, roll it tightly, secure the Velcro firmly, and tuck it away properly. An improper roll can cause seepage that might seem like it's coming from the pouch edge.
