peristalsis, segmentation and digestion?

[skye872]

Hello, My grandmother who had a (second) ileostomy on tuesday morning still does not have any bowel sounds, they returned much faster last month after her first surgery. Her feeding tube was restarted but there is no movement or absorption of the fluid. Sounds to me like there is no chemical digestion or peristalsis....how long long can a body stay in this kind of mode before her whole system shuts down? Or does anyone have experience with this and know about how long the bowel 'shock' last after this type of surgery. Any info would be greatly appreacated. Thanks Devin

hmm..no absorbtion of the food. I think that the problem is at Intestinal tenue in the part of ilium. (sorry I don't know what's the english name). Perhaps there's a problem with the villi and I can think it's related with autonom nerve specialized for digestion and absorbtion.
Another cause that I can think is the enzymes. there are some parts that's not working well in secreting enzyme (amilase, disakarase, peptidase, etc.) and that makes the polysaccharide and disaccharide aren't transformed into glucose. As you might to know that villi only can absorb glucose (the smallest part of carbohydrate). So, the absorbtion isn't optimal.
Another cause and the last that I can think is on the Vena Porta hepaticus, kinda a vein where glucose is transported to the Hepar (liver).[/i]

oh, another thought...villi is divided into 2 parts which is kil (to absorb glucose, vitamins, minerals, amino-acids, etc) and chyme (to absorb fatty acids and glycerol)
