Realistic structural details like mesentery, fat and connective tissue with veins tend to get left out of CG guts for sake of clarity, and that disappoints me.

Here's an example from an old photographic atlas of human anatomy showing an entire digestive tract from a very fresh cadaver with some evidence of diseased bowel. I've used and recolored some of this in manipulations. This image is reduced; highest resolution is always more desirable to work with.

Over the years I have assembled a morgue file (hah) of internal organ, wound and trauma images for reference and use as raw elements for photomanips, and would be happy to share what I've got in the chance you'd find them useful. I'll have to upload a large folder somewhere for that purpose soon.
