This topic is about finding the right ostomy system for someone who has a flat stoma and experiences issues like pancaking and leakage. The person is looking for advice on using convex two-piece closed ostomy systems effectively. Here are some helpful insights and tips shared by others:

- After surgery, the person had issues with pancaking and leakage using basic one-piece pouches. Switching to convex products helped eliminate leaks. Coloplast pouches are preferred for their opacity and viewing window.

- Covering the filter during showers prevents water from getting in, eliminating the need for using Saran Wrap or a hair dryer.

- With an output of only 1-2 times daily, a two-piece closed-end pouch is desired for easy disposal during short breaks, like a 10-minute school period.

- The person is currently using a Coloplast two-piece locking convex system but finds it difficult to snap together. Tips for easier snapping include:
1. Hook the bottom first, then slide fingers upward on both sides until the top clicks, and engage the lock.
2. Apply a thin film of water or lubricant around the hard rim to make snapping easier.

- To reduce pancaking or vacuum issues:
1. Use a small amount of lubricant inside the pouch to help stool slide down.
2. Place a wadded piece of gauze or crumpled toilet paper in the pouch to keep the sides apart.
3. Consider using drainable pouches that can still be discarded for emergency emptying.
4. Try flushable pouch liners to minimize mess.

- Product alternatives suggested include:
1. Coloplast Convex FLIP two-piece with a star-shaped flange for a good locking feel.
2. ConvaTec two-piece Moldable Technology with an optional "accordion" baseplate for easier pressing together, and a peek-a-boo viewing window.
3. Hollister products, which work with flushable liners.

- For longer-term management:
1. Explore colostomy irrigation, which might allow using a small stoma cap instead of a pouch for most of the day. Surgeons often recommend waiting about three months post-op.
2. Be prepared for changes in output patterns as healing and diet evolve.

- General tips for newcomers:
1. Experiment with different brands and components, and keep notes on what works.
2. Attend local ostomy support groups to see and pick up free sample supplies, and get guidance from an ostomy nurse.
3. Use national resources like the United Ostomy Association of America (UOAA) and Ostomy101.com for education on diet, skin care, travel, clothing, and more.

Additionally, the person keeps three "go-bags" of supplies in different locations for convenience and is considering discussing irrigation with a nurse to make daily care quicker and more routine.
