How is short-term tar like after colon cancer operation to return a responsibility

First: upper gastrointestinal or small intestinal bleeding stay in the intestinal cavity for a long time. After the destruction of red blood cells, hemoglobin combines with sulfide in the intestinal tract to form iron sulfide, which makes the stool black and shiny with mucus on the surface of stool, similar to tar. The iron in hemoglobin, under the action of gastric acid and intestinal bacteria, reacts with sulfide and turns into iron sulfide, which makes stool black.

Second: when the bleeding speed is fast and the amount is large, it can be accompanied by hematemesis or dark red bloody stool due to the short residence time of blood in the intestinal tract. In addition, the bleeding of biliary tract and pancreas, also can appear tarry stool. Jejunum, ileum, even the right colon bleeding, if stay in the intestinal tract for a long time, can also be manifested as melena. Taking drugs containing bismuth and eating animal's blood can cause black stool, which should be differentiated from upper gastrointestinal bleeding clinically.

Third: oily stool (especially with hematemesis) is a typical manifestation of upper gastrointestinal bleeding. Inflammation of esophagus, tumor, ulcer, cardia tearing syndrome, acute and chronic inflammation of stomach, peptic ulcer, gastric cancer, drug stimulation (such as acute and chronic gastric mucosal lesions caused by cortisone and aspirin), duodenal ulcer, diverticulum, inflammation, etc. can cause bleeding and tarry stool.
