ABSTRACT
Upper gastrointestinal endoscopy and double contrast barium radiology were compared prospectively in 45 Ugandan patients with AIDS and upper gastrointestinal oesophageal symptoms. Both investigating techniques were normal as was the histopathology in 5 patients. In 40 cases a definite pathological diagnosis (candidiasis; non-specific inflammation; malignancy) was made. Endoscopic examination provided a correct disgnosis in 38 cases; while only 15 cases were diagnosised from barium studies. Radiology was normal in 2 cases later proved to have definite pathology on endoscopy and histopathologic examination (oesophageal candidiasis). Endoscopy in this series was found to have 95sensitivity in diagnosing oesophageal disorders in AIDS patients; compared to a sensitivty of 37.5for radiology. The difference between the two procedures regarding sensitivity was statistically significant (p0.005). A combination of oral thrush and dysphagia was strongly associated with oesophageal candidiasis (positive predictive value 95; p0.0025). Endoscopy would be the ideal diagnostic procedure for oesophageal candidiasis. The above finding; however; provide a basis for empirical antifungal theraphy especially in places where diagnostic facilities are limited
