The periphery of the granulomas contain admixture of lymphocytes, plasma cells and  Langhans type of giant cells. Posted by Dr Vijay Shankar S | Nov 15, 2017 | Head & Neck and Gastrointestinal system, Systemic Pathology | 2 |, Tuberculosis affecting the intestines can be due to  primary or secondary infection. The 5‐factor predictive model 30 established by Wu and colleagues included two ITB‐predicted markers (pulmonary involvement and ratio of tuberculosis‐specific antigen to phytohaemagglutinin) and three CD‐predicted markers (perianal disease, longitudinal ulcer, and left colon involvement), whereas a 7‐factor predictive model 25 included age, diarrhoea, ring‐shaped ulcer, longitudinal ulcer, sigmoid involvement, suspicious radiological pulmonary tuberculosis and gender. Unfortunately, four patients died because of mistaken and delayed diagnosis followed by intestinal fistulas, severe abdominal infection and MODS within 6 months of self‐reported onset of disease. Although abdominal TB can be cured medically if treated early enough, the nonspecific presentation delays diagnosis in the majority of cases.

The specificity of ESR was such low that it only had a certain value in evaluating the curative effect. Note that the sensitivity  of AFB staining is very low (20%), yet  a positive  stain is 100% specific  for intestinal tuberculosis. From January 1991 to December 1996, 42 patients with intestinal tuberculosis were endoscopically examined and tissue culture, immunohistochemical stain, Ziehl-Neelsen stain, and polymerase chain reaction in fresh and fixed tissue were applied. Higher positivity and reliable results were found in tissue culture, Ziehl-Neelsen stain, and polymerase chain reaction. The higher incidence in men may be caused by unhealthy lifestyle factors such as migrant labour, poor working environment, higher labour intensity, alcoholism 4. La tuberculose intestinale (TBI) demeure répandue et représente un danger important pour la santé en Chine. Of these 37 surgical patients (Table 5), 25 had intestinal adhesion, 22 had enlarged mesenteric lymph nodes, 19 had intestinal stenosis, 16 had abdominal mass and 16 had peritonitis. The occurrence of bTB lesions from the organs of slaughtered cattle in Bauchi State, showed that the lungs had the highest number of suspected tissues 65 (54.20%), followed by the lymph nodes 28 (23.30%) while the heart, liver, spleen, intestines and mammary glands had the other 8.3%, 6.7%, 5.0%, 1.7%, and 0.8%, suspected tissues respectively. To avoid this vicious circle, a high diagnostic suspicion and early diagnosis are essential. Bacterial Inflammatory Enteritides. The Pathogenesis of intestinal tuberculosis is explained in the illustration below. Chest plain films examination found a high (67.1%) positive rate of pulmonary TB (Figure 2), indicating it was useful to differentiate ITB from other diseases like CD. If intestinal or lymph node involvement occurs, the differential diagnosis between an acute abdomen and other non surgical conditions may be a challenging problem. Initial diagnosis of all the patients with ITB. Only 17 (20.0%) of 85 ITB patients were initially diagnosed as ITB (Figure 5). Your email address will not be published. In this study, 19 (27.1%) of 70 patients had abdominal lymphadenopathy according to abdominal CT scan (Figure 3). The 14.3% positive rate for TB culture was in‐between earlier rates 6.9–50.9% 20, 28, 29. By ZN microscopic staining all 100% (2/2) of the intestines were positive for bTB, followed by the heart with 50% (5/10), then the lungs 29.23% (19/65); while the liver, lymph nodes, and spleen had 25%, 21.43% and 16.67% respectively were tested positive for bTB. General situation ; Etiology and pathogenesis ; Pathology ; Clinical manifestation ; lab other examination ; Diagnosis and differential diagnosis ; Treatment , prognosis and prevention ; 3 General ideas. These findings, which were comprehensively identified by endoscopy, gastrointestinal contrast examination, CT scans and surgery, were consistent with previous studies 4, 15. Laparotomy with a midline, area of obstruction consisting of a stricture of about 10-, cm in length with a proximal dilated segment and a, healthy apart from dilatation of the proximal bowel due, granulomas with Langhan’s giant cells involving the full, immune deficiency virus infection [1]. Abdominal TB comprises around 5 percent of all cases of TB worldwide [ 5 ]. This study was funded by the Chinese National Natural Science Foundation (Grant 81270945 and 81200327). Perforated ileal strictures were found in 30 per cent of those with acute symptoms. (d and e) Active tuberculosis in left upper lobe. 67,1% avaient une TBI secondaire à une tuberculose pulmonaire. Nineteen patients had a history of abdominal surgery, including eight appendectomies and two cholecystectomies. clinical evolution and the result of the complementary examinations, it was decided to initiate specific antituberculous treatment with the diagnosis of intestinal tuberculosis.

Indications included perforated viscus (2), acute abdomen (1), small bowel obstruction (1), colocutaneous fistula (1), pelvic neoplasm (1), and biliary colic (1). In the present study, the caecum was the third most involved sites of ITB. The bowel wall of ileocecum was circumferential thicken and the lumen was narrow (white arrow), accompanied with multiple abdominal lymphadenopathy (black arrow). HIV weakens a person's immune system so it can't fight the TB germs. Ileocecal tuberculosis is the most common site of gastrointestinal tuberculosis, which in turn is the third most common site of extrapulmonary tuberculosis. By comparison, the specificity of T‐spot TB was up to 92% in all patients 21. 2004 Nov;52:863-7. Forty‐five (52.9%) were diagnosed by demonstration of AFB in histological specimens. The sensitivity, specificity, positive predictive value, and negative predictive value in the diagnosis of TB were 100%, 73%, 86%, and 100%, respectively, for MR enterography and 88%, 70%, 83%, and 78%, respectively, for SBFT. Extra‐pulmonary TB accounted for 15% of the 6.3 million incident cases that were notified globally in 2016. The bacteria that cause tuberculosis are spread from one person to another through tiny droplets released into the air via coughs and sneezes.Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS. [Gastric tuberculosis: a report of 2 cases]. Les sites les plus fréquemment touchés étaient la valvule iléo‐colique (56 à 69,9%), l'iléon terminal (40 à 77,1%) et le cæcum (33 à 38,8 %). (c and d) Massive mucosal erosion, hyperemia, edema and polypoid hyperplasia in the terminal ileum; and biopsy showing granulomatous structures consisted of lymphocyte, Langerhans cells and epithelioid cell, and proved to be AFB positive. In resource‐poor countries, given that laboratory examinations, endoscopic, radiological, histopathological and microbiological examination are in short supply, diagnosis will continue to be mainly by clinical presentation, so a high index of suspicion is necessary. Les symptômes les plus communs étaient la douleur abdominale (88,2%) et la perte de poids (75,3%). Unfortunately, there were more cases (24.7%) of intestinal perforation in the current study, than in earlier studies (1.2–13%) 4, 8, 14, 20, probably due to the poor initial diagnosis rate and delayed treatment. The clinical, radiological and endoscopic characteristics of ITB are non‐specific, so diagnostic suspicion must be high in order to make an early diagnosis and ATT. 15 % of the 6.3 million incident cases that were notified globally in 2016 early diagnosis essential.
