Abstract
BACKGROUND: The gold-standard for diagnosis is growth of Mycobacterium tuberculosis on ascitic fluid or peritoneal culture. Due to the non-specific signs and symptoms of disease, its early diagnosis is difficult, especially in patients with decompensated cirrhosis. The reported sensitivity of ascitic fluid is low and to obtain tissue for peritoneal biopsy in patients with cirrhosis is difficult. Endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) is a good alternative to obtain peritoneal tissue for establishing the diagnosis of peritoneal TB. OBJECTIVE: To assess the role of EUS-FNA in the diagnosis of peritoneal tuberculosis in patients with decompensated cirrhosis. METHODS: Consecutive patients with peritoneal thickening, ascites and decompensated cirrhosis underwent EUS-FNA from the thickened omentum. Presence of granuloma or demonstration of acid fast bacilli was diagnostic of peritoneal tuberculosis. RESULTS: A total of 5 patients with CLD underwent EUS-FNA from omentum. FNA cytology revealed granuloma with multinucleated cells in all patients (100%) and AFB stain was positive in 2 of them (40%). CONCLUSION: We hereby report the use of EUS guided fine needle aspiration (FNA) of peritoneum as a newer, safe and unexplored technique for diagnosis of peritoneal TB.
