I have had my j pouch for 6 years and very often have difficulty passing gas. I NEVER attempt to pass gas without being seated on the toilet as I always pass a little bit of stool too. Sometimes I bend forward (as if to touch my toes) and this encourages gas to travel from my intestine and into the pouch. Spending a few moments like this often helps. I have constant stool leakage but that has nothing to do with the pouch and everything to do with a seton drain I have in for an abscess and fissure. I love my pouch!
