OMG! I am speechless about what you are dealing with! That is horrible. First of all a total blockage is life threatening and must be treated immediately! I went into ER of a major medical center and they knew exactly what to do. My surgeon, but I saw a group bc this is a teaching hospital, said they do NOT do surgery bc the scar tissue causes more medical problems...but they put me on Fentanyl and morphine for pain and gave me xRay contrast media through my NG tube (Nose/Gastro) and an IV of magnesium sulphate? to hopefully open the blockage. (This is how they treat all J-tube blockages.) No food or water from admittance until the blockage is open which took 4 days. No steroids. Then they sent mobile Xray every couple of hours to follow if it was working and opening the blockage. The NG tube sucked out blood and anything produced internally. I took 4 FULL days to unblock but they were sure it would work. I was discharged on Day 5 after I could consume soft solids and process them. This was my first blockage since my J-tube in 1991. It was caused by eating romaine lettuce and raw carrots!! But..every time I ate steak or beef for a month prior, I would throw up. So the blockage may have already begun. And they were sure if was also from adhesions which they saw on the x-Ray. I am so sorry you had to deal with this. My advice is find a doctor familiar with J-tube blockages, who really CARES and is available for you! I'm praying that you find better medical care who can help you manage your health issues better. Take care of yourself.
I wonder if they ever take care of a blockage by suctioning it out with a endoscope, if it is close enough to your anus that they could get the scope up the where the blockage is. That's what I always imagined they'd do, but I guess they don't?
