The difference between severe pancreatitis and mild pancreatitis
Generally speaking, mild pancreatitis is just a local inflammation of the pancreas, usually manifested as upper abdominal pain, nausea, vomiting, and bloating — symptoms of the gastrointestinal tract. Severe pancreatitis, however, is much more serious than mild pancreatitis. In severe pancreatitis, not only is the pain in the local pancreas area more intense and the abdominal bloating more pronounced, but there is also a lot of effusion accumulating in the abdomen. Severe pancreatitis can also affect many other organs, such as the lungs, which are most commonly affected. It can lead to patients developing acute respiratory distress syndrome, characterized by severe hypoxemia, with many patients requiring mechanical ventilation treatment. Another organ that is commonly affected is the kidney, with many patients with severe pancreatitis experiencing acute renal failure, reduced urine output, or even anuria. Severe pancreatitis can also affect the heart, brain, and other organs, leading to functional abnormalities in these organs. Therefore, besides affecting the local pancreas, severe pancreatitis can involve other important organs, resulting in multiple organ dysfunctions.
How to check for pancreatitis?
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.
Can severe pancreatitis be cured?
Severe pancreatitis can be cured, but because its complications are severe, it may be life-threatening. Severe pancreatitis is caused by a variety of etiologies leading to local inflammation, necrosis, and infection of the pancreas, accompanied by systemic inflammatory responses and persistent organ failure. Currently, comprehensive treatment for severe pancreatitis has become very mature, but its mortality rate is still as high as 17%. Currently, with a deeper understanding of the pathology, physiology, and disease progression of severe pancreatitis, there have been advances in treatment modalities, treatment concepts, and means of organ function support for severe pancreatitis. However, the mortality rate for severe pancreatitis remains high, though it can still be cured.
Two major signs of severe pancreatitis
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.
Symptoms of severe pancreatitis
The main symptom of severe pancreatitis is abdominal pain. This type of abdominal pain manifests as intense pain in the upper-middle abdomen, which radiates to the back and both sides of the body. The pain is widespread and severe, with about 95% of patients experiencing abdominal pain. Onset often occurs following binge eating or excessive drinking, and the pain worsens after eating. Another symptom is abdominal distension, which is also a common symptom. It is caused by extensive effusion in the abdominal cavity and retroperitoneum, as well as intestinal paralysis. Fever in the early stage of the disease is also a common symptom, resulting from the absorption of a large amount of necrotic tissue. Fever occurring in the later stages is often caused by infections triggered within the abdominal cavity.
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.
Severe pancreatitis diagnostic criteria
Diagnostic criteria for severe pancreatitis: First, based on the patient's clinical symptoms, symptoms such as restlessness, cold limbs, and mottled skin, indicative of shock, may appear. Second, physical examination signs, such as rigid abdominal muscles indicative of a positive peritoneal irritation sign, and Grey Turner's sign may also be present. Third, according to laboratory tests, the calcium levels generally significantly decrease, usually below 2 mmol/L, and elevated blood sugar levels greater than 11.2 mmol/L, typically without a history of diabetes. There may also be a sudden decrease in urine amylase. Fourth, diagnostic abdominal paracentesis reveals ascitic fluid with high amylase activity. Based on these points, severe pancreatitis can be considered.
Severe pancreatitis is what disease
Acute severe pancreatitis is a disease caused by various etiologies, characterized by local necrosis, inflammation, and infection of the pancreas, accompanied by systemic inflammatory response and persistent organ failure. The current mortality rate is still as high as 17%. The course of acute severe pancreatitis can generally be divided into three periods. First, the acute response period, occurring up to about two weeks after onset, is characterized by a systemic inflammatory response. Second, the systemic infection period, from two weeks to about two months, is characterized by infection of pancreatic or peripancreatic necrosis. Third, the residual infection period, occurring two to three months later, where the main clinical manifestation is systemic malnutrition.
What fruits can you eat with pancreatitis?
Patients with pancreatitis can eat some mild fruits, such as apples, bananas, peaches, kiwis, and strawberries. It is best to avoid more acidic fruits like oranges, lemons, and hawthorns. For cooler fruits, they can be soaked in warm water for a certain period before eating. Also, regardless of the type of food, fruit, or daily diet, it is important not to overeat.
Rescue of severe pancreatitis
Severe pancreatitis involves severe illness impacting multiple systems and organs across the body. The rescue of severe pancreatitis should be based in the ICU, with multidisciplinary cooperation. The first step is early fluid resuscitation, with crystalloid solution preferred, and it should be rapidly completed within 48 hours of onset. The second step involves support for circulation and respiration. The third step involves the maintenance of organ functions and the use of blood purification treatments. Early use of blood purification in acute pancreatitis can remove inflammatory mediators, regulate immune dysfunctions, and protect organ functions, potentially extending the survival time of patients with severe pancreatitis. The fourth step includes monitoring intra-abdominal pressure and preventing and treating abdominal compartment syndrome. Further treatments mainly include the use of agents to inhibit pancreatic enzymes and platelet activation, as well as early jejunal nutrition. Additionally, prophylactic use of antibiotics is required, and in cases of biliary acute pancreatitis, ERCP or sphincterotomy should be performed. The final approach is surgical treatment, which is reserved for patients who do not respond to or have poor results from conservative treatment.
