I have had this j-tube button for a year now. recently i have had problems with it clogging after the end of my feeding, when i try to flush it with a 60cc bulb syringe....my nutrition nurse recommended using coca cola . i did that, but i couldn't flush. so i put the coke in the bag and thru the pump. I primed it for a short while till i heard a "swish" and the solution started going thru faster. This is happening several times a week. I am seeing my GI in New York on Thursday. he is going to try to "unclog" it with a form of a brush or fine tube.....He wants to avoid putting in another tube as I am a high risk for anesthesia.... Has anyone gone thru this experience to have their tube unclogged?
