Karen, sweets, what i perfectly remember is that you had good transit time of your small bowel when you had the stoma, didn't ever need any kind of a laxative, stimulant etc and feeling great. there's NO reason the new loop/end of small bowel to create the stoma wouldn't work. these are all anxiety thoughts you're having!
as stipy said, the stoma location in relation to the small bowel depends on each individual, so that's something you'll have to find out from your surgeon only. as you know, my stoma is also a loop one and my surgoen told me it is 10 cm above the anatomosis site, so didn't lose that much of small bowel.
but actually, b/c my small bowel is so slow, my surgoen once suggested that we can go higher up in my small intestine and do the stoma 1 meter upper. well, it was long ago when he said that and i'm not sure about it. prune juice clears me out every day and im ok. i don't want to go through that experiment.
i'm sorry that you're probably feeling disappointed and all.. i hope you find peace and happiness with your decision ♥♥♥♥
