I had to have surgery b/c of my obstruction as well. I suffered for many years of being unable to get solid foods to pass after having a subtotal colectomy, I finally ended up living on Ensure drinks, clear broth, and jello (oh yeah, and lots and lots of surgar free popcycles and Jolly Rancher hard candies). When these things would not move through my bowels anymore, I was reduced to only jello and popcycles. After eating this way for 2 years and seeking medical help everywhere I could (and finding no help anywhere in sight), I ended up in the hospital in June 2007. I was close to death and given large amounts of IV fluids to stabilize my heart and kidneys. In Sept, I was giving an ileostomy (aka, life on a bag). I honestly have no idea how to answer you question. If I had a solution for you, I would share it with you. Please becareful with your diet. I do not want you to end up like me. Keep seeking for help and hopefully your luck will be better than mine.
