Idiopathic acute pancreatitis is a diagnostic challenge for gastroenterologists. The possibility of finding a cause for pancreatitis usually relies on how far the diagnostic study is taken. Endoscopic explorations such as endoscopic retrograde cholangiopancreatography and endoscopic ultrasonography can help to determine the cause of pancreatitis. Furthermore, microscopic bile examination and magnetic resonance cholangiopancreatography can also be helpful in the work up of these patients. In this article an approximation to the diagnostic approach to patients with idiopathic acute pancreatitis is made, taking into account the reported evidence with which to choose between the different available explorations.
