Acute pancreatitis is a sudden inflammatory process of the pancreas in which premature activation of digestive enzymes leads to autodigestion of the gland, local tissue injury, and a systemic inflammatory response. The most common precipitants are gallstones and excessive alcohol intake, with additional causes including hypertriglyceridaemia, certain drugs, trauma, and anatomical variants; groove pancreatitis represents an uncommon segmental form affecting the region between the pancreatic head, duodenum, and common bile duct. The clinical hallmark is severe epigastric pain radiating to the back, often with nausea and vomiting, and the disease ranges from a mild, self-limiting episode to severe necrotising pancreatitis complicated by infected necrosis, systemic inflammatory response syndrome, and multi-organ failure. Diagnosis rests on a compatible clinical presentation, elevation of serum pancreatic enzymes such as amylase and lipase, and cross-sectional imaging; severity and prognosis can be stratified using radiological grading, and correlation of the modified computed tomography severity index with biochemical markers helps gauge disease extent. Inflammatory mediators and cytokine cascades, of the kind studied in experimental systemic inflammatory response models, contribute to progression and distant organ injury. Management is largely supportive, centred on fluid resuscitation, analgesia, nutritional support, treatment of the underlying cause, and timely recognition of local and systemic complications.
