Classification

The revised Atlanta classification for acute pancreatitis classifies it as:

• Mild pancreatitis (interstitial or edematous): inflammation of parenchyma of pancreas without local or systemic complications.
• Severe pancreatitis (necrotising or organ failure): severe pancreatitis causing local and systemic manifestations.

Acute pancreatitis is further distinguished clinically into early phase (1st week) and late phase (after the 1st week).
