why choose the Jejunal segment?

[Tilda]

I have "a" small question...

 

Lets say a child has had several atempts of Nissen fundoplications to prevent GER (gastroesophageal refluxes), but all failed. They then use Jejunal interposition (closed of gastric cardia, and a part of jejunum was placed between esophagus and pylorus to create a secondary pathway).

 

Why do they choose the Jejunal segment?

Why not the Duodenum or Ileum?

 

Is it because of the Payer's patches in the Ileum and the Brunner's glands in the Duondenum? Or is there an other explaination?

 

Thankful for all help//

ps. A bonus question : What part of the digestive system decides when you're not hungry? Is it the nervous system, full stomach or glucose level?(not craving... hungry) (we all know that our glucose level can be low, even though we're full and vise versa )

perhaps it`s more compatible with stomach acids?

For your bonus I believe it is the nervous system. I am pretty sure thats what I read in my book yesterday at least....

As a diabetic, I can say that when my BSL's are low I tend to be more hungry than when they are high. Although, my blood sugar levels tend to fluctuate more than a normal person's will.
