Pathobiologic Processes

Figure 1 represents an overview of processes that need to be considered. This figure illustrates unique extrapancreatic and intrapancreatic cellular events/factors involved in disease pathogenesis. Examples of extracellular factors include vascular and neural participation in pancreatitis. Examples of intracellular events/factors are activation of digestive enzymes, inhibition of secretion, cell calcium, heat shock proteins, inflammatory signaling pathways, and cell death pathways.

Causes of Pancreatitis

Figure 3 shows the relative distribution of the conditions associated with acute pancreatitis. We will now discuss our understanding of several of the most important conditions. Of note, autoimmune pancreatitis will be discussed in a future review on chronic pancreatitis.

Acute Pancreatitis: The Clinical Disorder

This section describes current approaches to management of acute pancreatitis and its complications.

Use of Antibiotics

Prophylactic antibiotic therapy does not have a role in the treatment of patients with interstitial pancreatitis.1 Patients with pancreatic necrosis may appear clinically septic early or throughout their long hospitalization. The development of leukocytosis, fever, and, in some cases, organ failure would be suggestive of the development of infected necrosis or bacteremia. Under these circumstances, antibiotic therapy should be initiated during the evaluation period. Once cultures (including

Summary and Future Directions

There have been significant advances in the supportive management and clinical strategies in dealing with complications of severe acute pancreatitis. However, there has been little or no progress in treating the underlying disorder using information about the pathobiology of the disorder from experimental models. Because the disease process progresses during hospital observation in this disorder, it seems very likely that treatments designed to address the pathobiologic process in this disorder
