This topic is about finding alternatives to the Hollister pouching system for someone who is experiencing leaks after colon-cancer surgery. The surgery has changed the shape of their abdomen, which might be causing the leaks. Here are some suggestions and insights that might help:

1. Consider trying another major brand and request free samples:
- Coloplast options like SenSura Mio Click or SenSura Mio Convex Flip.
- ConvaTec.
- Other brands such as Safe n’ Simple, Marlen, Nu-Hope, Securi-T, and ConfiPlus.
- Most manufacturers offer sample kits so you can test them before making a decision.

2. Switch to convex appliances if the stoma is near scar "ripples":
- The Hollister 53900 convex pouch has helped some users with leaks.
- Coloplast SenSura Mio Convex Flip is designed for irregular, herniated, or scarred abdomens, and free samples are available.

3. Use accessory products to fill gaps and reinforce the seal:
- Barrier rings like Eakin Cohesive or Marlen Ultraseal can be pressed around the stoma before applying the wafer.
- Stoma paste, belts, and flange-extender strips can add extra security.
- Combining a barrier ring with paste and SenSura Mio Click has worked for some users.

4. For temporary leak containment when away from home:
- ConfiPlus pads can be placed over the existing pouch. They won't stop an under-wafer leak but can contain output long enough to get home. Free samples are available on their website.

5. Remember to protect your skin:
- Clean any output on the skin promptly to prevent irritation.
- If you suspect an allergic reaction, try changing one product at a time to identify the cause.

6. Practical tips:
- Shower with the pouch on and dry it afterward with a blow-dryer on low heat.
- Keep a stoma nurse involved if possible to help evaluate fit and accessories.
