The presence of fecal-like vomit is a clinical symptom of acute pancreatitis. Acute pancreatitis (acutepancreatitis, AP) is a relatively common type of acute abdomen, and its incidence accounts for the third to fifth highest incidence of acute abdomen. More than 80% of these patients have a mild condition, namely acute edematous pancreatitis, which can be cured non-operatively and is basically an internal disease. What do I need to pay attention to in the daily prevention of fecal vomit? Acute pancreatitis has a tendency to recur. Preventive measures include removing the causes and avoiding the triggers, such as abstaining from alcohol, not overeating, and treating hyperlipidemia. Gallstone disease plays an important role in the development of acute pancreatitis, so patients with a history of acute pancreatitis attacks should undergo cholecystectomy and common bile duct exploration at an early stage. Many infectious diseases can be complicated by acute pancreatitis, the symptoms are not obvious, and the pancreatitis will subside on its own after the primary disease heals, the common ones are mumps, viral hepatitis, infectious mononucleosis, typhoid fever, sepsis, etc. Ascaris entering the bile duct or pancreatic duct can bring in not only intestinal fluid but also bacteria, which can activate pancreatic enzymes and cause inflammation. The pathogenesis of acute pancreatitis caused by various etiologies is different, but has a common pathogenesis, namely pancreatic self-digestion caused by the activation of various digestive enzymes in the pancreas.
