This topic is about finding a high-capacity, drainable ostomy pouch that can help someone sleep longer at night without needing to wake up frequently to empty it. The person is concerned about the possibility of the pouch clogging when the output is thicker, as many high-output bags have a rigid nozzle that might not handle thicker output well. They are looking for specific recommendations on brands and products.

Here are some helpful insights and advice:

1. Even with a larger pouch, some night-time emptying is likely necessary. A bigger pouch can extend the time between empties but won't completely eliminate the need. Gas build-up can still cause ballooning and leaks.

2. The Coloplast Assura 2-Piece High Output Drainable Pouch is 16 inches long and has a clip closure instead of a rigid funnel, which reduces the chance of clogging with thicker output. Users suggest positioning it so the output can settle at the bottom when lying down.

3. The Coloplast SenSura Mio High-Output Pouch, Item #11472, is available from EdgePark. It features a Velcro roll-up tail and no rigid nozzle, and is noted as the "largest volume" standard-looking pouch at about 12 inches.

4. An irrigation sleeve can be used at night if you have a 2-piece system. These are available from Coloplast, Hollister, and ConvaTec and connect directly to the flange. They offer very large capacity, reduce ballooning, and are easy to rinse by running water through the open end. They also fold up and clip for security.

5. Using an irrigation sleeve instead of a pouch can greatly reduce noise and splashing when emptying, which can help partners stay asleep.

6. All high-output bags with funnel or nozzle ends can be used on an ileostomy. When the output is thick, you may need to "milk" or squeeze it out like toothpaste and rinse with a periwash or ketchup-style squeeze bottle.

7. Filters, such as charcoal vents on standard pouches, are generally ineffective for the amount of gas produced overnight. Large-capacity options or irrigation sleeves manage gas better.
