HIII!! I just wrote this to someone else so I thought I'd post it to you too...
I'm not going to sugar coat...honestly, even after almost two years I find the j-pouch tough. My j-pouch is "perfect" by all means in construction and function BUT my immune system and the disruption in my microbiome continues to cause me grief. Yes, j-pouches can be constructed wrong and give problems (rare) but you may always, as many of us prior UC'ers do, deal with IBD. It sucks and it's not going away in most cases. J-pouches (and perm ileos) make it manageable. Bonus!
I really thought after I removed my colon and got a j-pouch all would be like before...pre UC. It's not. It's different, you are altered just as with a perm ileo and no, I do not feel totally "normal." On good days, when I forget I have a j-pouch and have little urgency, I get excited like YES, I can do this...we are going to get through this! I also had my colon taken out rather suddenly after two severe flares so I didn't have years of "I'M SO SICK OF THIS UC" I felt healthy and "normal" and then just four months later my colon peaced out. So...I'm not saying you won't feel "normal" with a j-pouch but my disease process was short which led me to wanting to have that "normal" feeling again...not really understanding that with UC we never quite feel "normal" again.
Many times I wish I had a perm ileostomy. Mainly, because I used to travel and be outdoors a lot and it's difficult now. With the loop ileostomy (even though it was challenging at times) I could go anywhere, no urges, nothing. But...my husband reminds me that it was not easy either. WHEN the body behaves and the j-pouch functions, it's a magnificent thing...when it doesn't. ugh.
Mainly I find the urgency to be challenging. Yes, you can hold it but you know when it's time to empty. You don't have to learn to hold it...your muscles just "hold it" like before. I found the transition stage surprisingly easy and "the urge" feeling similar to when I had a colon. I guess ultimately, it's the same nerves telling us it's time whether once a day with a colon or eight with a j-pouch!
For urgency, Immodium and fiber helps a bunch as does a low carb, no sugar diet (for me) and then there is pouchitis....When I was so ill I didn't even know about pouchitis, I just wanted the misery to go away and not take any more drugs but pouchitis is a frequent guest in my j-pouch house and I wish I knew more about it prior to surgery. The loop ileo was great...(pouchitis who?) Not sure it would have swayed my decision but...
J-pouch recovery takes years. And this is a good thing! At a low point just a few months ago, I called my surgeon about j-pouch reversal surgery. She pleaded with me to wait. She keeps stats on all her patients and in MOST cases, the MINIMUM time for a j-pouch is two years to get balanced and in sync with the body. Now, those two years aren't all bad, not at all...and you will have much evolution in your function. It gets better...day by day...month by month...and I'm actually optimistic to see how it functions at 3, 4 and 5 years out. I bet yours might function even better since your body has already adapted to a perm ileo.
If it's one piece of advice I can offer, please take the time to find the best surgeon (which you might already have) and IBD clinic for post surgery issues! Remember, you have will have a familiar option even after a j-pouch should you not adapt well to it.
Going back to an ostomy after j-pouch would be possible I would think, although you would have less intestine for absorption. That would be a good question for your surgeon...also would you need a loop while the j-pouch healed?
I wish you all the best with your decision!
