For an elderly with dementia, to further avoid aspiration pneumonia should we replace the peg tube for a pej one. is that an option?consequences? thx

Quality of life...: Sometime a feeding tube is used but with advanced dementia, feeding tube often causes more harm than good. It is not easy, but significant illnesses reduces hunger and so one often does not feel hungry. Use of feeding tube thus equals forced feeding which is not a good thing. Have a family meeting; discuss the wish of the person and respect it. It is not easy. Good luck.

Yes it is an option: If she is having aspiration while receiving feedings via a peg tube, conversion to j- tube should diminish aspiration from gastric reflux( assuming there is no obstruction distally in the GI tract). If the aspiration is from swallowing, conversion will not help. If her dementia is profound, it may be helpful to discuss both medical and life goals with her physician or ethics board.
