It's called a "stoma" in english, you were close, lol.
Some people have complications like skin irriation if they have ileos and some have mental problems dealing with it. You can also get blockages, which are painful but solved fairly easily.
People who choose the j-pouch still go 4-8 times a day, some still have some urgency, also there is a chance of something called pouchitis, seems that most people get over that fairly easily too.
But to me, when i chose surgery, i looked at it this way.
I KNEW i HATED my life the way it was stuck in the house, takignall kinds of meds, not really living. And i read about people and i did see some people who were unhappy but most weren't. So i thought, Ok i KNOW i hate this, and if i have surgery i MIGHT hate it too, but then i am still in the same place just hating something different. And it was worth it to me, to take a leap of faith to see. So i did, second hardest decision i ever made in my life and i am sooo glad i made it.
Now, i think back to being sick and how horrible i felt and how much life i missed, especially when i am doing something fun, or eating something that i couldnt have before, and i think WHY did i think it was a good idea to just keep going sick, when i could have just had the thing out, it was attacking me, it didnt' wanna be there, lol, and been healthy for those 8 years.
