Nissen Wrap

I had my wrap done about 3-4 years ago. the first year or two was great. No heartburn, no vomiting, etc. However, the past year has been, to put it lightly, hell. If im not suffering from severe diarrhea and abdominal pain then i am suffering from severe constipation and pain. I have had the wrap "ballooned" twice and several EGDs and even a laporoscopy to generally check things out. Currently it has been 2 1/2 weeks since my last bowel movement. this is after mind u, I tried Milk of Magnesia, suppositories, enemas, and everyone's favorite Magnesium Sitrate. Nothing. I know this is gross, but the only thing to come out was when i had to literally reach in with a glove and pull some out. I was hurting that bad. I have been vomiting brown, foamy substance and in so much pain nothing they give me helps. my doctor ordered a Colonic Study and i go today to see the result. i dont know what else to do. i feel like the only person alive that has this going on and am at my wits end. please help.
