This topic is about dealing with leaks and pinholes in Hollister 8678 one-piece “Roll-n-Lok” pouches. If you've been using these pouches and noticed some issues, you're not alone. Here are some helpful tips and insights to consider:

1. It might be a defective batch. Some users have experienced similar problems with Hollister pouches, such as leaking seams or misaligned Velcro. It's a good idea to contact Hollister's customer service, provide them with the lot number, and ask for replacement boxes. They often replace them at no cost.

2. Quality-control issues with the Roll-n-Lok tails are not uncommon. If any stool remains in the neck while folding, the pressure from pressing the Velcro can cause the thin plastic at the heat-sealed corners to rupture. To prevent this, carefully wipe the inside of both tail edges before rolling.

3. Minor pinholes usually remain contained once the tail is fully rolled, unless the output is very liquid. In such cases, change the pouch when it's convenient for you.

4. If these problems continue, you might want to consider switching brands. Some users have suggested Salts Healthcare drainable pouches as a sturdier alternative. These can be imported or requested through suppliers.

5. A general tip from stoma nurses is to routinely wipe the inside surfaces of the opening before closing. This can help reduce stress on the seal and minimize leakage.

6. Providing continual feedback to Hollister, either through their website or by phone, may help improve their quality assurance over time.
