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 are the diagnostic symptoms of fecal-like vomit? 1, abdominal pain: most of the acute pancreatitis is sudden onset, manifested as severe epigastric pain, and mostly radiates to the back of the shoulder, and the patient feels a girdling sensation in the upper abdomen and lower back. The location of abdominal pain is related to the location of the lesion, such as the head of the pancreatic lesion is heavy, the abdominal pain is mainly in the right upper abdomen and radiates to the right shoulder; the lesion in the tail of the pancreas, the abdominal pain is heavy in the left upper abdomen and radiates to the left shoulder. The intensity of pain is consistent with the extent of the lesion. If it is edematous pancreatitis, the abdominal pain is persistent with paroxysmal aggravation, and the abdominal pain can be relieved by acupuncture or injection of antispasmodic drugs; if it is hemorrhagic pancreatitis, the abdominal pain is very intense, often accompanied by shock, and it is difficult to stop the pain by using general pain relief methods. 2, nausea and vomiting: the beginning of the onset of the disease, characterized by vomiting can not make the abdominal pain relief. The frequency of vomiting is also consistent with the severity of the lesion. In edematous pancreatitis, there is not only nausea, but also vomiting 1 to 3 times; in hemorrhagic pancreatitis, vomiting is violent or continuous and frequent dry vomiting. 3, systemic symptoms: there can be fever, jaundice, etc.. The degree of fever is consistent with the severity of the lesion. In edematous pancreatitis, there may be no fever or only mild fever; in hemorrhagic necrotizing pancreatitis, high fever may appear, and if the fever does not subside, there may be complications, such as pancreatic abscess. Jaundice may occur as a complication of biliary tract disease or as a result of compression of the common bile duct by an enlarged pancreatic head. These two causes of jaundice need to be differentiated with medical history and laboratory tests. In a very small number of patients, the onset of jaundice is very rapid and shock or death may occur without obvious symptoms or shortly after the onset of symptoms, which is called sudden death type or fulminant pancreatitis.
