Weston Price to the rescue here:

"...Short- and medium-chain fatty acids from fats such as milk fat or coconut oil or palm kernel oil are broken off from the triglycerides without the need for bile acids. They are then shuttled directly to the liver through the portal artery without the use of chylomicrons. In the case of a meal with a large amount of lauric acid, some of this medium-chain fatty acid does travel via chylomicrons through the lymph system.
So, in lymphangiectasia, the problem is fat clogs up the lymph system, and cholesterol is often low so I guess that might affect bile product. Having a fat that bypasses this process would be important, and that is what is touted about coconut oil. However, this article appears to be from 2004, and even back then it states that this thought about completely bypassing the lymph and bile system is not true. However, it appears that it,s largely true.
As for pancreatitis, I guess it might depend on the relationship of how the pancreas inflamed and the lymph system, and I don't have a clue about that
