Intestinal tuberculosis is a chronic, specific infection caused by invasion of the intestine by Mycobacterium tuberculosis, mostly secondary to extraintestinal tuberculosis, such as pulmonary tuberculosis, tuberculous peritonitis, and hematogenous tuberculosis. The routes of infection are: direct swallowing of droplets containing Mycobacterium tuberculosis, direct spread of localized tuberculosis lesions, and hematogenous infection. The disease is easily combined with tuberculosis of other organs, and is prone to intestinal adhesions, intestinal obstruction, intestinal perforation, etc. It requires formal examination to confirm the diagnosis, full anti-tuberculosis treatment and, if necessary, surgical treatment. It is recommended to visit a children’s hospital.
