Role of endoscopy and biopsy in the work up of dyspepsia.

Endoscopy is recommended as the first investigation in the work up of a patient with dyspeptic symptoms and is essential in the classification of the patient's condition as organic or functional dyspepsia. Although the correlation between mucosal alterations and symptom pattern is difficult, endoscopy will remain the initial investigation of choice for clinically relevant abnormalities that need proper detection and biopsy.
