Pancreatitis

The main causes described are gallstones and ethanol. Other noted causes include hypertriglyceridaemia, drugs, genetics, and ductal obstruction caused by calcification or neutrophil extracellular traps. Common bile duct stones can also lead to acute pancreatitis.

Acute pancreatitis is an inflammatory disorder of the pancreas associated with pancreatic injury and immune activation. The literature describes immune cell infiltration, especially neutrophils and M1 macrophages, and a disordered immune response that can drive systemic inflammatory response syndrome and systemic injury in severe disease. TLR4-mediated inflammatory signaling and NLRP3-inflammasome-related pathways are implicated in pancreatic damage and severe acute pancreatitis.

Gallstones and alcohol use are the most prominent risk factors in the supplied material. Hypertriglyceridaemia, drugs, and ductal obstruction are also noted, and common bile duct stones can predispose to acute pancreatitis. The literature also mentions genetics as a contributing factor.

Management is described at the modality level as hospital-based supportive care with diagnostic evaluation and imaging to assess severity and complications. For pancreatitis related to common bile duct stones, endoscopic retrograde cholangiopancreatography, surgery, and radiological stone extraction are used. The literature also notes that treatment decisions depend on identifying complications and the underlying cause.
