Ileal tuberculosis is caused by Mycobacterium tuberculosis infection! Intestinal tuberculosis is the most common form of tuberculosis of the digestive system. How are patients with ileal tuberculosis diagnosed? 1, strong positive tuberculin test, for cases with high suspicion of intestinal tuberculosis, if anti-tuberculosis treatment is effective for 2-6 weeks, the clinical diagnosis of intestinal tuberculosis can be made, such as lesions in the terminal ileum and colon, colonoscopy and biopsy can help diagnose and differential diagnosis, for those who have difficulty in diagnosis, mainly proliferative intestinal tuberculosis, sometimes it is necessary to dissect the abdomen to confirm the diagnosis. 2, clinical manifestations of long-term fever, night sweats, abdominal pain, diarrhea (or constipation) of young and strong patients. 3.Patients with pulmonary tuberculosis or other extra-intestinal tuberculosis whose original lesions have improved, but whose gastrointestinal symptoms and tuberculosis toxemia symptoms have worsened. 4.Patients with right lower abdominal mass with pressure pain, or incomplete intestinal obstruction of unknown origin. 5, gastrointestinal X-ray examination of the ileocecal region with signs of irritation, barium filling defect or stenosis. 6, Crohn’s disease to go from where the clinical manifestations of this disease, X-ray and endoscopic views are often similar to intestinal tuberculosis, must be carefully distinguished. The main points of differentiation include: no evidence of extra-intestinal tuberculosis, tendency to remission and recurrence, generally longer duration of disease, X-ray findings, although the lesion is mainly in the terminal segment of the ileum, but there may be other segments of the intestine involved, and segmental distribution, more complicated fistula or perianorectal lesions 7, right-sided colon cancer This disease is older than the onset of intestinal tuberculosis, often over 40 years of age. X-ray examination mainly shows barium filling defect and the lesion is confined to the colon. Colonoscopy and biopsy can determine the diagnosis of colon cancer. 8.Amoebiasis or schistosomiasis granuloma X-ray barium meal examination reveals signs such as irritation in the ileocecal region, narrowing of the intestinal lumen and shortening and deformation of the intestinal segment.
