Over 10 percent of all cases of acute pancreatitis are termed idiopathic, meaning there is no obvious cause. For most people with acute pancreatitis, there are no dietary restrictions , but the person may be unable to eat for a few days, or they may have to avoid solid foods. When the person starts eating again, they will probably be advised to follow a healthful, low-fat diet, and to eat small and regular meals.
The American Dietary Guidelines offer advice on a healthful, low-fat, diet. Pancreatitis can lead to potentially fatal complications. Heart, lung, and kidney failure may occur.
In severe cases, organ failure can happen around 48 hours after symptoms appear. Without treatment, these can lead to death. It is important to seek treatment as soon as possible if someone shows signs of acute pancreatitis. The doctor will ask the patient about symptoms and examine their abdomen. If certain areas of the abdomen are sensitive when touched, this could indicate acute pancreatitis.
In acute pancreatitis, the abdominal wall muscles will be rigid. When listening to the abdomen with a stethoscope, there may be very few or no intestinal sounds. If blood levels of amylase and lipase are higher than normal, the patient will most likely be sent to the hospital. The pancreas produces elevated levels of both chemicals during acute pancreatitis. However, blood tests may not be accurate if they are not obtained on the first or second day of illness.
This is because lipase and amylase levels are highest within the first few hours and return to normal after a few days. To determine the risk of complications, a doctor will want to ascertain how inflamed the pancreas is; the following tests may be performed:. Acute pancreatitis usually resolves in a few days with treatment, although some people may need to stay in the hospital for some time, depending on the cause and how severe the symptoms are.

A computed tomography Computed Tomography CT In computed tomography CT , which used to be called computed axial tomography CAT , an x-ray source and x-ray detector rotate around a person.
In modern scanners, the x-ray detector usually For this scan, people are also injected with a contrast agent. The agent is a substance that can be seen on x-rays. Because the images are so clear, a CT scan helps a doctor make a precise diagnosis and identify complications of pancreatitis. Magnetic resonance cholangiopancreatography Magnetic Resonance Imaging Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography Endoscopic retrograde cholangiopancreatography Endoscopic Retrograde Cholangiopancreatography Imaging tests of the liver, gallbladder, and biliary tract include ultrasonography, radionuclide scanning, computed tomography CT , magnetic resonance imaging MRI , endoscopic retrograde cholangiopancreatography During this test, doctors are able to remove from the bile duct gallstones that are causing a blockage.
In endoscopic retrograde cholangiopancreatography ERCP , a radiopaque dye is introduced through an endoscope a flexible viewing tube , which is inserted into the mouth and through the stomach into the duodenum the first segment of the small intestine. The radiopaque dye is injected into the biliary tract just past the sphincter of Oddi. The dye then flows back up the biliary tract and often shows the pancreatic ducts. Surgical instruments can also be used with the endoscope, allowing a doctor to remove a stone in a bile duct or insert a tube stent to bypass a bile duct blocked by scarring or cancer.
If doctors suspect that there is an infection, they may withdraw a sample of infected material from the pancreas by inserting a needle through the skin into the fluid collection. Urine may also be tested for an enzyme called trypsinogen. This enzyme is secreted by the pancreas. If the level of this enzyme is elevated in the urine, the person may have pancreatitis. In acute pancreatitis, a CT scan helps determine the outlook or prognosis. If the scan indicates that the pancreas is only mildly swollen, the prognosis is excellent.
If the scan shows large areas of destroyed pancreas, the prognosis is usually poor. A number of scoring systems help doctors predict the severity of acute pancreatitis, which can help them better manage the person.
These scoring systems may include information such as age, medical history, physical examination findings, laboratory tests, and CT scan results. However, in pancreatitis with severe damage, or when the inflammation is not confined to the pancreas, the death rate can be much higher. Death during the first several days of acute pancreatitis is usually caused by failure of the heart, lungs, or kidneys.
Death after the first week is usually caused by pancreatic infection or by a pseudocyst that bleeds or ruptures. Treatment of mild acute pancreatitis usually involves short-term hospitalization where fluids are given by vein intravenously , analgesics are given for pain relief, and the person fasts to try to rest the pancreas.
A low-fat, soft diet is usually started soon after admission if there is no nausea, vomiting, or severe pain. People with moderately severe acute pancreatitis need to be hospitalized for a longer period of time and are given intravenous fluids. As long as people can tolerate eating and drinking, they can continue to do so while they are ill.
If people are unable to eat, they are given food through a tube that is inserted through the nose and into the stomach or intestine tube feeding Tube Feeding Tube feeding may be used to feed people whose digestive tract is functioning normally but who cannot eat enough to meet their nutritional needs. Such people include those with the following Symptoms such as pain and nausea are controlled with drugs given intravenously.
Doctors may give antibiotics if these people show any signs of infection. People with severe acute pancreatitis are admitted to an intensive care unit Types of units People who need specific types of care may be put in special care units.
Intensive care units ICUs are for people who are seriously ill. These people include those who have had a sudden, general Blood samples are repeatedly drawn to monitor various components of the blood, including hematocrit, sugar glucose levels, electrolyte levels, white blood cell count, and blood urea nitrogen levels. A tube may be inserted through the nose and into the stomach nasogastric tube to remove fluid and air, particularly if nausea and vomiting persist and ileus Ileus Ileus is a temporary lack of the normal muscle contractions of the intestines.
If possible, people with severe acute pancreatitis are given nutrition via tube feeding. If tube feeding is not possible, people are given nutrition through an intravenous catheter that has been inserted into a large vein intravenous feeding Intravenous Feeding Intravenous feeding is used when the digestive tract cannot adequately absorb nutrients, as occurs in severe malabsorption disorders.
It is also used when the digestive tract must be temporarily For people with a drop in blood pressure or who are in shock, blood volume is carefully maintained with intravenous fluids and drugs and heart function is closely monitored.
Some people need supplemental oxygen, and the most seriously ill require a ventilator a machine that helps air get in and out of the lungs. When acute pancreatitis results from gallstones, treatment depends on the severity. While people are still in the hospital, doctors typically remove the gallbladder. Pseudocysts that have rapidly grown larger or are causing pain or other symptoms are usually drained.
Depending on its location and other factors, a pseudocyst can be drained by placing a drainage tube catheter into the pseudocyst. The catheter can be placed using an endoscope or by inserting the catheter directly through the skin into the pseudocyst. The catheter allows the pseudocyst to drain for several weeks. Surgery is rarely needed to drain a pseudocyst. An infection or necrotizing pancreatitis is treated with antibiotics, and may require removal of infected and dead tissue endoscopically or surgically.
Acute pancreatitis is sudden inflammation of the pancreas that may be mild or life-threatening but usually subsides. Attacks of pancreatitis vary greatly in severity and length.
Mild attacks of acute pancreatitis may resolve within a week. Severe attacks may take several weeks to resolve. Yes, acute pancreatitis can recur. Risk of recurrence varies greatly depending on the cause of the pancreatitis and whether risk factors have been eliminated for example, by removing gallstones, abstaining from alcohol, and stopping smoking.
Doctors do blood tests to detect enzymes released by the inflamed pancreas and do imaging tests such as computed tomography CT or ultrasonography to look for complications.
People get intravenous fluids and medicines to relieve pain and nausea. When vomiting has subsided, people will be allowed to drink fluids and eat a low-fat, low-fiber, soft diet. People who cannot eat may be fed through a tube in their stomach. Complications may require surgery. Because alcohol is a risk factor for pancreatitis, doctors usually advise people who have had acute pancreatitis to avoid drinking.
The amount of risk from drinking varies among people depending on the cause and severity of the pancreatitis, but it is safer to avoid drinking. Doctors typically allow you to drink water once your nausea and vomiting have subsided enough that you can tolerate drinking liquids.
Yes, severe pancreatitis can be fatal. Yes, but only rarely after a very severe case. Most of the time, the pancreas is still able to do its normal functions, including making insulin and controlling your blood sugar. Conversely, others look sick, sweat, have a fast pulse beats per minute and shallow, rapid breathing. Rapid breathing is due to inflammation and the accumulation of fluid in the chest cavity.
Blood pressure tends to fall when a person with AP stands, causing faintness. As the disease progresses, people tend to be less and less aware of their surroundings—some are nearly unconscious. Occasionally, the whites of the eyes sclera become yellowish. In certain people, the initial symptom may be shock or coma. Normally, the pancreas secretes pancreatic fluid through the pancreatic duct to the duodenum.
This pancreatic fluid contains inactive digestive enzymes and inhibitors that inactivate any enzymes that become activated on the way to the duodenum. Blockage of the pancreatic duct by a gallstone stuck in the sphincter of Oddi stops the flow of pancreatic fluid. Usually, the blockage is temporary and causes limited damage, which is soon repaired. But if the blockage remains, activated enzymes accumulate in the pancreas, overwhelm the inhibitors, and begin to digest the cells of the pancreas, causing severe inflammation.
The pathogenesis of acute pancreatitis is not fully understood. Gallstone Pancreatitis: Because the gallbladder and pancreas share a drainage duct, gallstones that lodge in this duct can prevent the normal flow of pancreatic enzymes and trigger acute pancreatitis. Alcoholic Pancreatitis: Alcohol is a common cause of acute pancreatitis. Alcoholic pancreatitis is more common in individuals who have a long history of alcohol abuse.
Drug-Induced Pancreatitis: A number of drugs used to treat medical conditions can trigger acute pancreatitis. Published case reports of drug-induced AP exist for at least 40 drugs of the top most prescribed medications. Hereditary Conditions: Acute pancreatitis can be caused by hereditary conditions, such as familial hypertriglyceridemia and hereditary pancreatitis.
These conditions usually occur in children and young adults. This condition is called idiopathic pancreatitis. Only a small proportion of this group will experience additional attacks over time.
Most cases of ERCP-induced pancreatitis are mild. The functions of the common bile duct and the pancreatic duct are to drain the gallbladder, liver, and pancreas; the two main ducts convey the bile and the pancreatic juice through the papilla into the duodenum.
The most common reason that someone would need an ERCP is a blockage of one of these ducts often due to gallstones. Endoscopic techniques look for abnormalities such as blockages, tissue irregularities, problems with the flow of bile or pancreatic fluid, stones, or tumors, and endoscopic methods have replaced surgery in most patients with common bile duct and pancreatic disease.
While any patients who need ERCP are hospitalized, the procedure is sometimes done on an outpatient basis. Damage to the pancreas may permit activated enzymes and toxins—such as cytokines—to enter the bloodstream and cause low blood pressure and damage to organs outside of the abdominal cavity, such as the lungs and kidneys.
The part of the pancreas that produces hormones, especially insulin, is usually not affected. This may occur because the stomach is distended or has been moved out of place by a mass in the pancreas that causes swelling, or because the movement of stomach and intestinal contents has stopped ileus.
In severe AP, parts of the pancreas die necrotizing pancreatitis , and blood and pancreatic fluid may escape into the abdominal cavity, which decreases blood volume and results in a large drop in blood pressure, possibly causing shock. Severe AP can be life-threatening. Pancreatic pseudocysts collections of pancreatic enzymes, fluid, and tissue debris form in and around the pancreas can become infected.
If a pseudocyst rapidly grows larger and causes pain or other symptoms, the clinician drains it. In severe AP, a CT scan can help determine the prognosis. If the scan indicates that the pancreas is only mildly swollen, the prognosis is good.
If the scan shows large areas of destroyed pancreas, the prognosis is poor. Death during the first several days of AP is usually caused by failure of the heart, lungs, or kidneys.
Death after the first week is usually caused by pancreatic infection or by a pseudocyst that bleeds or ruptures. The reported annual incidence of AP has ranged from 4. Acute pancreatitis is a leading cause of hospitalization in the United States, and the incidence is increasing in many European and Scandinavian countries owing to increased alcohol consumption and better diagnostic capability.
Diagnosing AP can be difficult because the signs and symptoms are similar to those of other medical conditions. The diagnosis is usually based upon a medical history, a physical examination, and the results of diagnostic tests see TABLE 1. Once a diagnosis of AP is made, additional tests are needed to determine the underlying cause. This ensures that the correct treatment is given to prevent pancreatitis from recurring.
Imaging Tests: Imaging tests provide information about the structure of the pancreas, the ducts that drain the pancreas and gallbladder, and the surrounding tissues. Tests may include an x-ray of the abdomen may show dilated loops of intestine or, rarely, one or more gallstones , x-ray of chest, CT scan detecting inflammation of pancreas , or MRI of the abdomen.
