All the risks and benefits need to be understood. I consider PT tubes a last resort when bile can not be routed to the small intestines. You have to understand that if it is draining to an external bag, it is not being used in your body for its intended purpose and this impacts digestion and overall well being.
I would only consider a PT tube if the risks of infections are too great or the blockages or strictures are causing serious jaundice. The liver creates a tremendous amount of bile. My brother empties his bag 4-5 times per day and it adds an extra 30 minutes to his morning routine to clean, flush, rebandage. He says he would do anything to get rid of the bag, he feels it limits his activity and feeling of wellness with the bag strapped to his wasit or thigh. They currently are talking about adding a second tube and bag to the left side of his liver and he says “no way”.
