Abdominal tuberculosis in children. Report of 10 cases.
BACKGROUND
Abdominal tuberculosis is a rare location of this infection with a lot of diagnostic difficulties. The aim of this study was to review our experience of pediatric abdominal tuberculosis with that of the literature data.


METHODS
A retrospective study was conducted over a 7-year period; 10 cases of abdominal tuberculosis in children were reviewed (6 girls and 4 boys, mean age: 11 years, extremes 4-14). Eight patients enrolled in this study satisfied the following criteria: a positive culture for mycobacterium tuberculosis on samples of ascites fluid, sputum, urine, abscess puncture and/or caseating granulomas on histologic examination of biopsies obtained by endoscopy, percutaneous aspiration or needle biopsy or exploratory laparotomy. Two other patients (patients No 1 & 5) had a favorable response within 10 weeks of antituberculous therapy.


RESULTS
We observed 8 cases of peritoneal tuberculosis and 2 cases of intestinal tuberculosis. Extra-abdominal tuberculosis was found in 4 of those patients. Two patients had a contact with a tuberculosis positive individual. Nine children had BCG immunization. The main clinical features were abdominal distension (6 cases) and abdominal pain (6 cases). Abdominal ultrasonography visualized mesenteric lymphadenopathies (6 cases), an abdominal mass (5 cases), free (1 case) and localized ascites (1 case). Barium enema and small bowell series showed small bowel stenosis (1 case) and ileal ulcerations (1 case). Exploratory laparotomy, performed in 3 patients, showed whitish granulations and peritoneal abscesses with caseous necrosis on histology. Quadruple therapy with tuberculostatic agents was prescribed in all patients, associating isoniazid, rifampicin, pyrazinamide combined at the start of the treatment with streptomycin (7 cases) and ethambutol (3 cases). Short term outcome was favorable with no deaths. The long term outcome was complicated by persistent ascites (1 case) and the development of portal hypertension (1 case).


CONCLUSIONS
Abdominal tuberculosis remains a rare localization with a lot of diagnostic difficulties.
