Ileostomy take down after Ileorectal Anastomosis?

I do not want this post to be redundant but I did search the site for past threads related to Ileostomy take-down after Ileorectal Anastomosis. I could only find threads related to a take down after J-pouch / Ileoanal anastomosis.

These threads were helpful in that I am sure that many of my experiences will relate (i.e., very sore bottom due to acidic BM, careful what I eat at first, etc.) but I am wondering if anybody can weigh in on experiences related to the IRA surgery? I know this surgery is far less common but I am hoping somebody might have some feedback.

I also have a question that probably pertains to anybody that has ever had a take down. Almost immediately after I eat (and it does not matter what I eat as I have logged it and tried everything) my stoma goes crazy, erupting and quickly (within say 10-15 minutes) fills the bag with completely watery diarrhea. However, after that the stool quickly returns to a much thicker consistency - about that of toothpaste. It remains thicker until the next time I eat...and the pattern repeats.

I am worried after the take down surgery that every time I eat I will have an immediate, almost uncontrollable need to run to the bathroom.
I have tried Loperamide but the problem is that it actually stuffs me up, even in small doses, since my stool generally "thickens up" and the diarrhea is only immediately after I eat.

Anybody had this happen, or still have it happen?

Thanks for any feedback - I have been haunting this board for years but only recently registered to become part of the community.
