    Transcript

    00:01 In this section, we take a look at gastrointestinal disease of the stomach and the duodenum.

    00:08 We begin by looking at GI bleeding.

    00:12 Forms of GI bleeding and what it means to you clinically.

    00:16 If there’s Hematemesis, well, if you’re thinking about vomiting up a blood and usually it indicates bleeding proximal to the ligament of Treitz.

    00:27 The ligament of Treitz is dividing your GI system into a proximal and a distal portion.

    00:34 And it is a line between the duodenum and the jejunum.

    00:37 So technically speaking, that in which you find bleeding that's taking place proximal to the Treitz may result to hematemesis.

    00:46 Melena Melena to you should mean that there’s enough time of the blood to then set into the feces.

    00:53 And so therefore by the time the feces has then evacuated, the stools then appears to be black and tarry.

    01:00 Therefore, for the most part though, Melena should indicate upper GI bleeding.

    01:06 But technically speaking, it can occur anywhere from the GI tract.

    01:10 Anywhere.

    01:12 However, if it is a Hematochezia then this should be bright red.

    01:16 And this to you should indicate that the bleeding is quite distal more so in the colon.

    01:22 Give yourself an example such as hemorrhoids in which sometimes you have bleeding that takes place and coats the stool as being frank or bright red.

    01:33 Or things of the colon cancer type especially right sided colorectal cancer in which here also the stool might then appears being bright red.
