Acute severe pancreatitis is caused by many reasons, including binge eating, especially consuming a large amount of high-fat diet, excessive drinking, obstruction of the pancreatic duct by gallstones in the bile duct, pregnancy, hyperlipidemia, etc. These lead to disorders in pancreatic secretion, resulting in pancreatic juices digesting the pancreas itself and leaking into the abdominal cavity, leading to symptoms such as abdominal effusion. It is classified as severe pancreatitis based on reaching a certain score in some assessments. Severe pancreatitis often accompanies dysfunction of organ systems, common examples include acute respiratory distress syndrome characterized by stubborn hypoxia and respiratory failure, acute renal failure shown by anuria or oliguria, and acute gastrointestinal failure, which manifests as high abdominal pressure and severe intestinal motility disorders, including abdominal distension.
