What's better for a senior after a stroke and dementia, a peg or pej tube. which one is more likely to have less regurgitation and aspiration pneumoni?

Neither: Will prevent aspiration because patients still need to manage secretions (saliva). Both provide reliable nutrition although pej tubes are smaller diameter so they can clog easier.

Pej tube: The pej tube is placed into the jejunum of the small intestine and therefore less likely to result in gastroesophageal re-flux which could lead to aspiration into the lungs.

No evidence: Unlikely that either will prevent aspiration.
