Endoscopic retrograde cholangiopancreatography should no longer be used as a diagnostic test: the case against

Endoscopic retrograde cholangiopancreatography has been used successfully in diagnosis of pancreatico-biliary diseases. Over the past decade, there have been tremendous developments in radiological technologies which have led to the emergence of new and less invasive modalities like endoscopic ultrasound and spiral computed tomography and magnetic resonance cholangiopancreatography. Understandably, the usefulness of diagnostic endoscopic retrograde cholangiopancreatography is being questioned primarily because of its potential attendant complications. Therefore, this controversial question needs to be debated in the gastroenterology community. In this article, we compare the efficacy of newer diagnostic tools with existing "gold standard" modality--endoscopic retrograde cholangiopancreatography, and put forward our arguments in favour of a continuing role for endoscopic retrograde cholangiopancreatography as a diagnostic tool in certain circumstances.
