    Abstract:
    BACKGROUND: Abdominal tuberculosis is still a medical problem in developing countries. AIMS: To analyse the clinical, laboratory, ultrasonography and computed tomography findings and to discuss the diagnostic approach of 19 patients with peritoneal tuberculosis. PATIENTS: Nineteen patients diagnosed in our department, with peritoneal tuberculosis (8 female, 11 male; mean age: 47.89 +/- 4.3 years) between 1996 and 2002, were studied retrospectively. METHODS: All clinical, laboratory, radiological findings, and diagnostic methods were reviewed. RESULTS: The most common symptoms and signs of the disease in these patients were abdominal pain, ascites, weight loss and night sweats. On conducting skin test, eight patients (42%) were found to be positive, while all the patients had elevated serum cancer antigen 125 levels, but acid-resistant bacilli could not be demonstrated on the direct preparation. In three patients (15.78%), the ascitic fluid culture was positive. The most common ultrasonographic and computed tomographic findings were ascites, septation in the ascites, peritoneal thickening, mesenteric and omental involvement. An abnormal chest X-ray, suggestive of previous tuberculosis was present in three patients. Diagnosis was made by image-guided percutaneous peritoneal biopsy in 18/19, and by histological examination of biopsy specimens obtained via laparoscopy in 1/19. Laparoscopy was only performed in 1 of the 19 patients due to lack of sufficient material for histological diagnosis by percutaneous biopsy. Of the biopsy specimens, 84% revealed caseating granulomas, while 16% were non-caseating. Acid-fast bacilli were seen on the Ziehl-Neelsen stain in 18 patients. CONCLUSIONS: Peritoneal tuberculosis should be considered in the differential diagnosis of exudative ascites. Image-guided percutaneous peritoneal biopsy seems to be a sufficient, safe and inexpensive method for diagnosis of peritoneal tuberculosis.
