Sjan810,
How frustrating-I'm sorry you didn't get any answers. Can you get a second opinion with another surgeon? I had one surgeon tell me what you heard, but the other one said adhesions cause all of this and they aren't usually able to catch them on scans. Have the scans caught anything related, like dilated bowel loops or anything? That is what my surgeon saw on mine despite not seeing a clear obstruction point--they said this only happens if something is blocked.
