Geez Roberta, I had a hiatal hernia repaired about 15 years ago, then had to have it redone after blowing it out during a rugged case of bronchitis. Those two surgeries combined with an old fashioned gallbladder surgery when I was 28 messed up my innards like you wouldn't believe. This past winter I was supposed to have a colonoscopy but a pretest showed another (new) hernia that allowed the colon to migrate up into my chest and press against my lungs. I was finally scheduled for surgery on 28 May and when they got in they discovered a vast array of scar tissue and some serious adhesions. My spleen had become attached to my colon and part of my stomach and when they tried to remove it from the other body parts it started to hemorrhage so they yanked it out. Oh yeah, then my left lung collapsed and they had to shove in a chest tube (good times in the OR)
I think my point is that when they monkey around in your innards, the innards take on a life of their own and occasionally rearrange themselves. I kind of expect doctors (esp surgeons) to remember this when they are treating people who have had multiple procedures of the non-cosmetic kind.
I'm sorry about the narrowed innards, I feel your frustration.
