I. etiology and pathogenesis The main route of infection of intestinal tuberculosis is through mouth infection. The most common overall site is the ileocecal region. Heres a summary of what we learned before: Crohns disease occurs at the end of the ileum The predilection sites of ulcerative colitis are rectum and sigmoid colon The predilection site of colon cancer is sigmoid colon. Two. Pathology Intestinal tuberculosis mainly located in ileocecal or ileocecal valve and its adjacent ileum and colon, followed by other parts of the ascending, transverse and descending colon, jejunum, duodenum and sigmoid colon, appendix, etc., a few found in the rectum, stomach, esophagus.

It is called ulcer type. It is characterized by a band of ulcers whose vertical length is perpendicular to the long axis of the intestine. The prominent clinical feature is diarrhea. 2., hyperplasia type intestinal tuberculosis features: rarely occur diarrhea, prone to constipation. The lesion is limited in the ileocecal valve, can have a lot of tuberculous granuloma and hyperplasia of fibrous tissue, make local bowel wall thickening, stiff, also visible tumor like lump human intestinal cavity, the lesions in the intestinal lumen narrowed, easy to cause obstruction. Extended knowledge: Banded in shape, and its length is perpendicular to the long axis of the intestine: ulcerative intestinal tuberculosis A large flask with a large body: Amiba Irregular map of the gut: bacillary dysentery. Three. Clinical manifestation 1. abdominal pain 2. dia
