title: Upper gastrointestinal endoscopy in an urban hospital in northern Nigeria: association of presenting features with endoscopic findings.
abstract: In 326 fibreoptic upper gastrointestinal (GI) endoscopies performed in Evangel Hospital (Jos, Nigeria), pathology was found in 210 patients, and of a major nature such as peptic ulcer disease or cancer in 129 of these. The three most useful features to predict the presence of major pathology were epigastric tenderness (the single most useful feature), loss of weight and epigastric pain of a burning nature. These features were selected by stepwise discriminant analysis, which also led to the conclusion that the presence of at least two of these three features is an even more powerful predictor of major pathology.
