Abstract :

Objective: Comparision of the mycobacteriological yield from gastric lavage (GL) and onchoalveolar lavage (BAL), in children with pulmonary tuberculosis. Methods: 116 children with chest radiograph suggestive of tuberculosis and positive Mantoux test or a positive history of family contact with a case of tuberculosis were prospectively subjected to gastric lavage on three consecutive mornings and onchoalveolar lavage on the last day. The samples were subjected to bacteriological isolation. Results: Samples from 20 (17.2%) children grew Mycobaterium tuberculosis from gastric lavage and 24 children had their BAL positive for this bacteria ( p>0.05). Overall mycobacterial isolation was possible in 40 patients (34.4%) as four children had grown Mycobacterim tuberculosis in GL as well as BAL. Addition of BAL to the diagnostic work up, increased the mycobacteriological yield from 17.2% with gastric lavage alone to 34.4% when BAL was also performed (p = 0.013). Conclusion: No difference seen in mycobacterial isolation rates from gastric lavage and BAL when studied in isolation. However, when both GL and BAL are used; these procedures complement each other to double the diagnostic yield.
