How did tuberculosis of intestine happen? 's general knowledge
Tuberculosis of intestine is that the tubercle bacillus infringes the chronic specific infection that the intestine cause, about 90% are caused by Bacillus tuberculosis. It is mostly 20- 40 years old to suffer from age, women slightly exceed men.
The tubercle bacillus infringes the intestine to infect from the mouth. The patient have more open pulmonary tuberculosis or throat tuberculosis, because often annex the phlegm liquid including tubercle bacillus, and cause a disease; Or often the meal with the open pulmonary tuberculosis patient altogether, ignore the tableware to sterilize and isolate, can also cause a disease; If drink and does not undergo the disinfecting disease-carrying milk or dairy products, the ox type tubercle bacillus can also happen and infect.
In addition tuberculosis of intestine can also competent to sow scattered to cause, meet to one type tuberculosis of millet by blood, or is spread directly by pelvis tuberculosis or tuberculosis peritonitis,etc..
Whether the emergence of tuberculosis depends on the result that the human body interacts with the tubercle bacillus or not. Being infected by the above-mentioned route is a pathogenic condition, there is more quantity of only when invading tubercle bacillus, virulence is relatively great, and when the unusual or some resistance of immunological function of organism is weakened, could have illness coming on.
Tuberculosis of intestine good to send position for go back blind department, other position rise colon, jejunum, transverse colon, descending colon, appendix, duodenum, second form marry, minority see in the rectum, there are reports of tuberculosis of stomach occasionally.
The tubercle bacillus is apt to go back to the blind department to cause pathological change, mainly involved in following factors:
(1)In normal and physiological cases, intestines content thing in front of not passing, answering blind sphincter, it is relatively long the time of the terminal ileum that held up in, in addition the colon near end wriggles instead, make the intersection of intestines and the intersection of content and thing in time that caecum stay long, increase tubercle bacillus to go back, the intersection of caecum and chance that mucous membrane keeps in touch and infringes in this way.
(2) Going back to the blind department has abundant lymphoid tissues, and the tubercle bacillus is aptest to infringe the lymphoid tissue.
Generally speaking, tuberculosis of intestine can be divided into a common ulcer type and rare hyperplasia type two kinds, its pathologic change fixes with situation of human immunity to tubercle bacillus and allergic response. If human body's irritated reaction is strong, pathological change relies mainly on exudative, look on as and infect mushroom quantity more, virulence is great, there can be a kind of necrosis of cheese, form ulcer, is called ulcer type tuberculosis of intestine. Diarrhoea is one of the common symptoms of one type tuberculosis. If the organism immunity is in good condition, it is relatively light to infect, is shown as the granulation and organized hyperplasia, can fiber take further, call hyperplasia tuberculosis of intestine, so that secret for behave mainly often originally type.
