title: Use of endoscopy in diagnosis and management of patients with dysphagia in an African setting.
abstract: The objectives of this study were to define the utility of esophagogastroduodenoscopy in the diagnosis and management of patients presenting with dysphagia and to determine the relative incidence of the various causes of dysphagia in Sudan. This is a prospective, cross-sectional, descriptive, hospital-based study carried out at the endoscopy unit of Soba University Hospital, Khartoum, Sudan. All patients complaining of dysphagia underwent upper gastrointestinal endoscopy with therapeutic intervention when necessary. A total of 114 patients were enrolled in the study, with a mean age of 47 years SD +/- 19 and a male to female ratio of 1 : 1.04. A benign condition was diagnosed in 56% of the cases; this included esophageal strictures in 21% of the cases and achalasia in 14%. Malignant causes were mainly due to esophageal cancer (40.4%) and cancer of the stomach cardia (3.5%). Therapeutic intervention was attempted in 83% of the cases. Risk factors predictive of a malignant etiology were age over 40 years (P < 0.000), dysphagia lasting between 1 month and 1 year (P < 0.000), and weight loss (P < 0.000). A barium study was performed in 35 cases (31%) prior to endoscopic examination and proved to be inaccurate in three cases (8.6%). Upper gastrointestinal endoscopy in our African setting is an accurate and useful investigation in the diagnosis and management of patients presenting with dysphagia. Patients over the age of 40 years presenting with dysphagia and weight loss are more likely to have a neoplastic disease and should be referred for urgent endoscopy.
