In patients with severe pancreatitis, physical examination may reveal abdominal distension with tympanic percussion sounds, prominent tenderness in the upper middle abdomen, and potentially widespread abdominal pain centered in the upper middle area. Some may exhibit rebound tenderness, moderate muscle tension is common, and a few cases may demonstrate shifting dullness. Occasionally, a mass in the upper middle abdomen can be palpated, possibly due to fluid in the lesser sac. Auscultation may reveal diminished or absent bowel sounds, accompanied by cessation of passing gas or stool, indicating features of paralytic ileus.

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.

How many days of fasting for acute pancreatitis?

The duration for which patients with acute pancreatitis must fast is determined by the severity of their condition. Some may only need to fast for a day or two, while others may require around three to four days, or even a week. In severe cases of acute pancreatitis, it might be difficult to say how long the fasting could last, potentially around two weeks. Once patients with pancreatitis start eating after a series of active treatments such as anti-infection measures, inhibiting pancreatic secretion, replenishing electrolytes, and balancing acid-base levels, and following treatments like using rhubarb to facilitate bowel movements, if their bowel movements and gas expulsion have mostly returned to normal and amylase levels have largely normalized, they can cautiously start consuming low-fat, high-vitamin, and high-calorie liquid foods.

Treatment of severe pancreatitis

Severe pancreatitis must be managed with comprehensive measures and aggressive rescue treatment. For medical treatment, the first step is to enhance monitoring of vital signs such as heartbeat, respiration, and blood pressure. The second step involves actively replenishing fluids and electrolytes to maintain effective blood volume. Severe cases often experience shock, and it may be appropriate to administer albumin, plasma, etc. The third step for patients with severe pancreatitis, who typically have high metabolic demands, is to enhance nutritional support, possibly using parenteral nutrition. The fourth step involves routine use of antibiotics for severe pancreatitis to prevent infections related to pancreatic necrosis. The fifth step involves using somatostatin analogs like octreotide to suppress the secretion of pancreatic enzymes and pancreatic juice as part of conservative medical treatment. If pancreatic necrosis is complicated with infection, or if a pancreatic abscess forms, surgical treatment can be considered.

How is acute pancreatitis treated?

Acute pancreatitis is classified into mild pancreatitis and severe pancreatitis depending on the severity of the condition. Mild cases often recover within a week without residual effects; severe cases are perilous with a poor prognosis, and the mortality rate ranges from 20% to 40%. Treatment for mild pancreatitis includes fasting, gastrointestinal decompression, pain relief, antibiotics, intravenous nutrition, acid suppression, enzyme inhibition, etc. In addition to the aforementioned treatments, severe pancreatitis requires strict medical monitoring to maintain electrolyte balance, early parenteral nutrition transitioning to enteral nutrition, and the use of antibiotics to reduce pancreatic fluid secretion, such as the growth inhibitor octreotide, as well as enzyme activity suppressants like gabexate. If the pancreatitis is biliary in origin, an ERCP with a sphincterotomy of the sphincter of Oddi may be performed. In case of serious complications, surgical treatment may be considered. (Medications should be used under the guidance of a doctor.)

Severe pancreatitis symptoms

Severe pancreatitis, due to different stages of pathological changes, presents diverse systemic responses. Generally, mild symptoms of pancreatitis include abdominal pain, nausea, vomiting, and fever. In severe pancreatitis, apart from these symptoms, due to bleeding, necrosis, and autolysis of the pancreas, additional symptoms such as shock, high fever, jaundice, abdominal distension, and paralytic ileus, peritoneal irritation signs, and subcutaneous ecchymosis may also occur. Abdominal pain is the earliest symptom, while nausea and vomiting are manifestations due to inflammatory factors stimulating the vagus nerve. The likelihood of jaundice is relatively low in acute edematous pancreatitis but is more common in severe pancreatitis. Extensive inflammatory exudation in the pancreas can lead to pancreatic necrosis and localized abscesses, which may cause varying degrees of fever increase.
