In this section, we’ll take a look at gastrointestinal disease of the stomache and the duodenum.
Begin by looking at the GI bleeding,
forms of GI bleeding, and what it means to you clinically.
If there’s a hematemesis, well, you are thinking about vomiting up of blood
and usually indicates bleeding proximal to the ligament of Treitz.
The ligament of Treitz is dividing
your GS system into a proximal
and a distant portion
and there’s a line between the duodenum and jejunum, so technically speaking
that in which you find bleeding that’s taking place, proximal to the treitz may result in Hematemesis.
Melena to you should mean that there’s enough time of the blood to descend into the feces.
And so therefore by the time the feces then evacuated.
The stool then appears being black and tarry.
Therefore, for the most port though.
Melena should indicate upper GI bleeding, but technically speaking
It can occur anywhere from the GI tract. Anywhere.
然而 如果有便血 它会是鲜亮的红色
However, if it is a Hematochezia. Then this would be bright red.
And this to you should indicate the bleeding is quite distal.
More so, in the colon. Given us an example such as
In which sometimes you have bleeding that takes place and coats.
The stool was being frank or bright red.
Or things of…
things of colon cancer type, especially colorectal cancer
in which here also the stool might then appears being bright red.
