Pancreatitis can cause acute abdominal pain, along with symptoms of nausea and vomiting, and severe cases can lead to hypotensive shock. In laboratory tests, the diagnosis is generally made by assessing serum or urine amylase levels. An amylase level that exceeds three times the normal value can diagnose pancreatitis. Additionally, ultrasound and CT scans can reveal an enlarged or exuding pancreas, and the presence of a small amount of fat necrosis around the pancreas can be diagnosed as pancreatitis. The onset time of serum amylase in pancreatitis varies; typically, serum amylase begins to increase between 6 and 12 hours and starts to decline after 48 hours, and can be detected within 3 to 5 days. Lipase levels typically start to rise between 24 to 72 hours and remain elevated longer, up to 7 to 10 days. Thus, lipase has diagnostic value for later stages of pancreatitis and tends to have higher specificity compared to amylase.

Severe pancreatitis complications

Complications of severe pancreatitis primarily include: 1. Acute peripancreatic fluid collection and interstitial edematous pancreatitis, where fluid accumulates around the pancreas without necrosis. This can be diagnosed with enhanced CT. 2. Pancreatic pseudocysts, characterized by fluid encapsulated by a clearly defined inflammatory cyst wall around the pancreas, with no or minimal necrosis, commonly occurring around four weeks after an episode of interstitial edematous pancreatitis. 3. Accumulation of acute necrotic material, involving necrotic tissue and liquids from necrotizing pancreatitis, including the parenchyma and peripancreatic tissues, also diagnosable through enhanced CT. 4. Encapsulated necrosis, observable as a clearly defined inflammatory encapsulation of the pancreas and peripancreatic tissues, commonly occurring four weeks post an episode of necrotizing pancreatitis.

What can be eaten with severe pancreatitis?

Patients with severe pancreatitis should not eat orally. Historically, suppressing pancreatic enzyme secretion by resting the intestines has been considered an important means of controlling the progression of acute pancreatitis. Currently, the implementation of early enteral nutrition is proposed. Early enteral nutrition should be administered via a jejunal tube, which is safer. The nutritional formulation should be chosen based on the patient's condition and intestinal tolerance. Initially, only glucose water may be used to allow the intestines to adapt to the nutrition. Early nutrition should use low-fat preparations containing amino acids or short peptides, because whole proteins entering the intestine directly without being digested by stomach acid can cause indigestion. As the condition enters the recovery phase, the feeding amount and rate can be gradually increased, and preparations containing whole proteins may be given.

Pancreatitis is what?

Pancreatitis is a relatively common disease in gastroenterology, generally believed to be caused by various factors leading to the activation and autodigestion of the pancreas itself, resulting in inflammatory changes in the pancreas. Common causes include bile duct stones, alcohol consumption, and overeating, among others. Clinically, it is most commonly presented with symptoms such as abdominal pain, bloating, nausea, and vomiting. Fever may also accompany these symptoms. The diagnostic criteria for pancreatitis generally include three standards: The first is typical upper abdominal pain, persistent upper abdominal pain; the second is a blood test showing blood amylase levels more than three times the normal value; the third involves typical abdominal imaging, such as ultrasound, CT, or MRI, indicating imaging changes like pancreatic effusion. If two out of these three criteria are met, pancreatitis can generally be diagnosed.

Severe Pancreatitis Criteria

Acute pancreatitis with persistent organ failure lasting more than 48 hours is considered severe pancreatitis. In the early stages of the disease, organ failure starts with a systemic inflammatory response produced by the activation of a cytokine cascade, involving the continuous failure of single or multiple organs. Such patients often have one or more local complications, with organ failure that can persist for several days after onset. The mortality rate can reach 36% to 50% once organ failure occurs. Infections in such patients can dramatically increase the mortality rate. CT imaging may show gas bubbles in peripancreatic necrotic tissue and fluid collections. Diagnosis is confirmed by positive results from either a smear of aspirate obtained via image-guided fine-needle aspiration or from bacterial cultures.

Severe pancreatitis treatment process

Severe pancreatitis generally develops rapidly, progresses urgently, and can even be life-threatening. Therefore, the main treatment initially involves fasting, gastrointestinal decompression, suppression of pancreatic enzyme secretion, promotion of gastrointestinal motility, and maintaining regular bowel movements. Antibiotics can be used to prevent infection and necrosis of pancreatic tissue. If necrotic pancreatic tissue and ascites occur in the abdominal cavity, appropriate puncture and drainage may be used.
