Which statement describes pancreatitis pathophysiology?

Which statement describes pancreatitis pathophysiology?

• A. Bile duct obstruction without pancreatic inflammation.
• B. Autodigestion of the pancreas due to proteolytic enzymes.
• C. Autoimmune destruction of pancreatic islets.
• D. Vascular occlusion of the splenic artery.

Answer: (B)

Pancreatitis occurs when digestive enzymes, especially proteolytic enzymes like trypsin, become activated inside the pancreas rather than in the gut. This premature activation leads to autodigestion of pancreatic tissue, causing inflammation, edema, hemorrhage, and fat necrosis. The resulting inflammatory response can extend beyond the pancreas, contributing to severe pain and potential organ dysfunction. This description—autodigestion of the pancreas due to activation of proteolytic enzymes—best captures the disease’s pathophysiology. Other options describe different processes: biliary obstruction without pancreatic inflammation isn’t pancreatitis; autoimmune destruction of pancreatic islets is type 1 diabetes; vascular occlusion of the splenic artery would cause ischemia rather than pancreatitis.
