The aim of the study was to characterize the value of combined endoscopy of tracheobronchial tree and oesophagus within 1 session for diagnosis of HIV-associated disorders. Hospitalized HIV-positive patients who underwent combined flexible broncho-oesophagoscopies between 1999 and 2002 in 2 units for infectious diseases were studied retrospectively. 54 HIV patients were analysed; 89% were at stage CDC C, 79% were male, mean age was 40 y. Bronchoscopy led to a diagnosis in 57.4% (95% CI 43.2-70.8). In 40.7%, these were AIDS-defining events (ADE) and 16.7% were general disorders (GD). Oesophagoscopy was diagnostic in 46.3% (95% CI 32.6-60.4). In 35.2% these were ADE, and 11.1% were GD. Patients with pathological oesophagoscopy had a significantly lower CD4 cell count and a higher viral load. There was no association of pathological bronchoscopy with pathological oesophagoscopy regarding ADE. No severe complication was recorded. It is concluded that combined flexible broncho-oesophagoscopy is a valuable and safe method for the diagnosis of HIV-associated disorders. The diagnostic output is highest in patients with advanced disease. A pathological finding in oesophagoscopy cannot be predicted by the presence of bronchoscopic abnormalities. Prospective studies are necessary to confirm these results.
