My uncle's digestive track has been blocked due to malignancy and he is not able to eat or drink anything.
Sorry to hear that your uncle's treatment was so problemmatic.
I am no doctor, but depending on the specific situation, an enteral feeding tube might be fitted.
Mind you, an aunt of mine had sufferred Crohn's disease for many years. Eventually, they had resected so much of her small nitestine that she had to be on intravenous feeding. She survived with this for about 10 years. This didn't stop her from chewing and enjoying food, she just couldn't swallow it.
