This topic is about finding a reliable solution for persistent leaks in a colostomy bag, despite using stoma paste. The person experiencing this issue is looking for practical advice to achieve a secure and long-lasting seal. Here are some helpful insights and suggestions:

1. Consider using a belt, such as one from Hollister, to help stop leaks. These can be obtained from stoma product vendors.

2. Barrier rings have extended wear time to 1.5 days. Trying convex flanges and stacking rings might help level out dips around the stoma.

3. Since the stoma sits low and has dips causing leaks, the poster's wife continues to perform changes due to limited visibility.

4. Warming the wafer with a hair-dryer might improve adhesion, but be cautious of skin burns. Using multiple rings at once is also a consideration.

5. If free samples of sealing rings are unavailable, purchasing them might be necessary.

Advice and insights for managing leaks:

- Skin preparation:
- Use residue-free soap like yellow Dial and avoid lotions, perfumes, and moisturizers.
- Shave peri-stomal hair, ensure the area is completely dry, and check for irritation. Treat redness with products like liquid Mylanta if needed.
- Apply an alcohol-containing skin-prep wipe for a tacky surface, such as Bard Barrier Wipes.

- Sealing products and techniques:
- Stop using paste and try moldable barrier/sealing rings like Eakin Cohesive Seals, Hollister Adapt Barrier Ring, or Convatec equivalents.
- Place the ring directly on prepared skin, then apply the flange. For cost-effectiveness, cut the ring into smaller pieces and use only where needed.
- Use convex flanges or rigid convex baseplates for dips or slight retractions.
- Warm the wafer after application with a hair-dryer on low or a hand-held fan to improve adhesion.
- Press firmly around the stoma with a Q-tip or bottle to meld the ring and wafer.
- Reinforce edges with 3M medical tape or half-moon elastic barrier strips for extra security.

- Appliance choices and sampling:
- Consider switching to a two-piece system with a larger, softer flange for longer wear times.
- Request free samples from manufacturers like Hollister, Convatec, and Coloplast.
- Order a catalog and samples from Edgepark Medical Supply at 1-800-321-0591.
- If a brand's adhesive fails, try other brands as body chemistry varies.

- Belts and accessories:
- Most two-piece baseplates have side loops for an adjustable ostomy belt, which can help eliminate leaks.

- Dietary and output considerations:
- Eat multiple small, low-fiber, higher-protein meals to reduce volume, gas, and liquidity.
- Monitor stool consistency, as very watery output or excessive gas can undermine the seal.

- Professional support:
- Consult an experienced, certified ostomy nurse for fitting, convexity assessment, and teaching.
- Attend local ostomy support group meetings for problem-solving and product recommendations.

- Alternative strategies:
- Once the technique is mastered, irrigation (if medically appropriate for a colostomy) can provide longer pouch-free intervals.
