Ever-increasing diversity of drug-induced pancreatitis

Figure 1 Flow diagram to help identify the potential cause of acute pancreatitis, including cases of drug-induced pancreatitis. ERCP: Endoscopic retrograde cholangiopancreatography; FDA: Food and Drug Administration.

Figure 3 Proposed drug-induced pancreatitis probability assessment scale in which a total summative score of > 9: highly probable, 6-8: probable, 3-5: possible, and ≤ 2: doubtful. ERCP: Endoscopic retrograde cholangiopancreatography; EUS: Endoscopic ultrasound; MRCP: Magnetic resonance cholangiopancreatography.
