Which factor commonly contributes to acute pancreatitis by obstructing the pancreatic duct?

• A. Hypertriglyceridemia.
• B. Gallstones obstructing pancreatic duct.
• C. Hypertension.
• D. Chronic peptic ulcer disease.

Answer: (B)

Blockage of the pancreatic duct leads to a buildup of pancreatic secretions and premature activation of enzymes inside the pancreas, triggering inflammation and autodigestion. The most common obstructive cause is gallstones that migrate into the bile duct and lodge at the ampulla of Vater, where the pancreatic and bile ducts share a channel. This obstruction prevents normal drainage of pancreatic juice, precipitating acute pancreatitis. Hypertriglyceridemia can cause pancreatitis through metabolic and inflammatory pathways rather than by blocking the duct. Hypertension and chronic peptic ulcer disease do not typically obstruct the pancreatic duct and are not common direct causes of this obstructive mechanism.
