Acute pancreatitis is usually a sudden and severe illness caused when the pancreas rapidly becomes inflamed. Pancreas enzymes and various poisons (toxins) may enter the blood stream in an acute attack, and injure other organs such as the heart, lungs and kidneys.
Definition of Organ Failure:
In the case of AP, 3 organ systems are considered most important i.e. respiratory, renal and cardiovascular which are most commonly involved.
Your gallbladder, liver and spleen surround your pancreas. The right side of your body contains the head of your pancreas. This narrow organ lies along the first segment of your small intestine, called the duodenum. The left side of your body houses the tail of your pancreas.
Sometimes people with severe acute pancreatitis can develop a complication where the pancreas loses its blood supply. This can cause some of the tissue of the pancreas to die (necrosis). When this happens, the pancreas can become infected, which can spread into the blood (sepsis) and cause organ failure.
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.
The largest study to date of patients who have had surgery for chronic pancreatitis with follow-up of six years or longer has found that about two-thirds survive after 10 years.
Patients with chronic pancreatitis are at an increased risk of developing pancreatic cancer and should be fully evaluated if symptoms worsen, particularly if duct stricture develops.
The most common complication of acute pancreatitis (occurring in approximately 25% of patients, especially those with alcoholic chronic pancreatitis) is the collection of pancreatic juices outside of the normal boundaries of the ductal system called pseudocysts (Figure 23A). Most pseudocysts resolve spontaneously.
Background Multiple organ failure (MOF) and infected necrosis are both considered severe adverse events during the course of necrotizing pancreatitis.
People with chronic pancreatitis may have no symptoms until the condition has caused severe damage to the pancreas. However, abdominal pain that spreads to the back remains the most common warning sign. Chronic pancreatitis may also cause diarrhea, weight loss, or greasy, unusually foul-smelling stools.
A: Chronic pancreatitis is a serious illness and, in some cases, can be fatal. A small number of people with chronic pancreatitis will develop pancreatic cancer, which can be fatal. Small numbers of people with chronic pancreatitis may die from complications following surgery or from a digestive hemorrhage.
Gallstones — Gallstones (including microlithiasis) are the most common cause of acute pancreatitis accounting for 40 to 70 percent of cases [14].
Animal studies have suggested that the exocrine pancreas possesses an intrinsic capacity for regeneration and thus can make a rapid and full recovery from exocrine diseases such as acute pancreatitis. By contrast, the endocrine islets have limited regenerative capacity in adults.
Pancreatitis has two stages — acute and chronic. Chronic pancreatitis is a more persistent condition. Most cases of acute pancreatitis are mild and involve a short hospital stay for the pancreas to recover. Acute pancreatitis occurs suddenly after the pancreas is damaged.
Mild acute pancreatitis has a very low mortality rate (less than 1 percent),1,2 whereas the death rate for severe acute pancreatitis can be 10 to 30 percent depending on the presence of sterile versus infected necrosis.
Once an infection has occurred, it can quickly spread into the blood (blood poisoning) and cause multiple organ failure. If left untreated, infected pancreatic necrosis is almost always fatal. Infected pancreatic necrosis usually develops 2 to 6 weeks after the symptoms of acute pancreatitis starts.
Most people recover completely from acute pancreatitis. If it's not a severe case, you'll feel better in five to 10 days. In severe or complicated cases, you may need to stay in the hospital for several weeks.
The most frequent causes of death were: pancreatic cancer (3.6%), complications after surgery (3.6%) and upper digestive hemorrhage (2.4%). The mortality risk factors were presence of diabetes, no alleviation of pain under treatment and unceasing of smoking.
It usually builds up quickly (over a few hours) and may last for several days. The pain can become severe and is typically felt spreading through to the back. The pain may be sudden and intense, or it may begin as a mild pain that is aggravated by eating and slowly grows worse.
Chronic pancreatitis causes severe damage to your pancreas. This means that your body won't be able to make needed enzymes and hormones. This can result in malnutrition, because you won't be able to digest foods. Chronic pancreatitis can also cause diabetes.
Acute terminal pancreatitis (ATP) was defined as a postmortem entity of localized acute pancreatitis without any clinical evidence of pancreatic disease.
