Acute pancreatitis.

In order to recognize acute pancreatitis in the setting of the acute abdomen, the surgeon must be thoroughly familiar with the numerous etiologies of the disease. No specific test is available to diagnose acute pancreatitis. CT scanning is arguably the most useful single tool, but surgical judgment is critical. Most cases of acute pancreatitis resolve spontaneously without sequelae, but the spectrum of the disease also includes highly lethal forms associated with a variety of systemic complications. Operative intervention is indicated when other, more rapidly fatal, abdominal processes cannot be reliably excluded and when local complications develop.
