Dr. Calvin Coffey.
Here is a link to a TED talk he did, I think those of you with Mesenteric problems would find it very interesting. He has great visuals, and also talks about how even now, Doctors are being taught incorrect information about the mesentery.
* * I just had to take off the link to the Ted talk and the article below because I am not allowed to post them.
The talk is very good - if you search his name and Mesentery it should come up - I think it's about the only video on you tube about the mesentery!

Here is a link to a recent review article he wrote.

Sorry I couldn't post the link: try searching Dr Coffey and "The mesentery: structure, function, and role in disease"

I just saw this comment under his you tube video:
"I just heard of him, but it took 47 years for me to be diagnosed with a twisted mesenteric root. I have been in chronic pain my whole life."

I am a scientist, and approach this problems with that mindset. From my limited research, it seems that that very little is known about pathology of the mesentery, except for a definitive problem like panniculitis. Given that, it seems premature to me if someone has an abnormality with it, and is also symptomatic to just dismiss it as a cause or contribution. There really isn't any research. I also wonder if twisting or structural abnormalities are even reported sometimes, because it might not be what the radiologist is looking for (i.e. if someone has abdominal pain, they would likely focus on the bowels and more 'well known organs" . Just some thoughts.
