Yes, ileostomy is a bag outside of the body from the small intestine. They make a stoma out of the end of the small intestine then a few times a week you change the appliance. This is like a picture frame type of big band aid that goes around the stoma with a hole cut in it for the stoma to stick through. Then you attach the bag that clicks onto a little ring. Then the poop goes into the bag. I tend to get diarrhea easily IF I eat too much salt or sugar. BUT out of 4 years, I have only had about 4 serious bouts of this. Once was from bad water in Greece and immodium stopped it.
I could not have my small intestine hooked to my rectum because both my colon and rectum were too injured to save. Plus my small intestine had bad adhesions. This all from a PRIOR surgery that on review did not need to be done. BUT I was lucky to find someone to fix my small intestine and give me the bag. Better than dying which is where I was heading. So I'm thrilled to be alive, traveling, and ballroom dancing.
You would not go down the road I did as what you would need likely is your colon removed and your small intestine hitched to your rectum if tests proved your rectum worked. This could even be done laporoscopically and not open so fewer adhesions. So you may get a great result. But get all the tests no matter where you have this done.
All of us on here did not get perfect results no matter what our original issue was. BUT those not on here who did get perfect results have moved on and no longer post, So you have to figure there are a LOT of successes. Most of us are on here because we were made better or are looking for info or improvement. Any surgery is a gamble. Just decide if this affects your life enough, then get a full workup, go on many radiology AND surgical consults then make your choice. My first surgery, removal of sigmoid colon, turned out to be based on an incorrectly read radiology scan. this was where I got into trouble not knowing the scan was misread in the first place. No patient thinks to have their scans on DVD read by other radiologists. So just a word from one who has been there, get the testing, then have other radiologists look at it. THEN you will have covered all your bases. Then check out your prospective surgeons by looking to see how many medmal suits they have (if any) at the court house nearest them (civil superior court clerks office). ANy doc can have one or two, but my original surgeons had 13 combined suits counting claims against them with our state medical board, I did not know how to check this out at the time. So here are helpful hints from me. They are the ones who injured my colon and rectum beyond repair.
MOST docs you need to realize are accurate, caring, and wanting what is best for you. I just happened to fall into bad hands. BUT I was also lucky to find one to save my life. That is how I got my ileostomy. It is my "life saver" The stoma sort of looks like one. Do remember also in time the small intestine slows down to partially take over the function of the colon, so the fast moving really thin liquidy poop all mostly quiets down in 6 to 9 months or even less for some people. I had normal transit, so for me, it took longer to slow, BUT people who had transit issues, their small intestine calms down in likely fewer months.
