AIM: To analyze diagnosis and treatment of patients with tuberculous peritonitis, to develop the algorithms for instrumental examination and differential diagnosis. MATERIAL AND METHODS: There were 48 patients with tuberculous peritonitis. The examination included radiography, abdominal and thoracic computed tomography, ultrasound, and laparoscopy. All patients underwent histological, cytological, microbiological and molecular-genetic analysis of abdominal exudate and peritoneal biopsy. Exclusion criterion was signs of secondary peritonitis. RESULTS: Clinical picture of tuberculous peritonitis was accompanied by nonspecific symptoms. Previously identified pulmonary tuberculosis and HIV-infection were present in 93.8 and 70.8% of patients. Diagnostic laparoscopy of abdominal cavity as the main method of instrumental diagnosis together with cytological, molecular-genetic and microbiological research of peritoneal exudate and tissue specimens were useful to determine diagnosis in 87.2-95.8% of cases. CONCLUSION: Tuberculous peritonitis may be assumed in patients with previous tuberculosis of lungs or other localizations, HIV-infection. Computed tomography is the most informative method to diagnose tuberculous peritonitis. Diagnostic laparoscopy is indicated for suspected tuberculous peritonitis. This procedure is supplemented by peritoneal biopsy, cytological, molecular-genetic and microbiological examination of peritoneal exudate and tissue specimens.
