Pancreatitis

What Is Pancreatitis?

Pancreatitis means inflammation of the pancreas. Pancreatitis is a unique type of inflammation. Generally, the digestive enzymes produced by the pancreas remain inactive until they reach the intestine. However, if these enzymes become activated while still inside the pancreas, they can begin to digest pancreatic tissue itself (auto-digestion), causing inflammation. Pancreatitis can be a serious and potentially life-threatening condition.

It is commonly seen in men aged 30–40 years.

Types of Pancreatitis

There are two main types:

  • Acute pancreatitis — sudden and severe inflammation of the pancreas.
  • Chronic pancreatitis — long-term or repeated inflammation of the pancreas.

Causes of Pancreatitis

Pancreatitis can have one or more causes. For example:

Acute Pancreatitis

Common causes include:

  1. Gallstones (gallstone pancreatitis): A gallstone can block the area where the bile duct and pancreatic duct drain into the intestine. This is one of the most common causes of acute pancreatitis.
  2. Heavy alcohol use (alcoholic pancreatitis).
  3. Very high levels of lipid/cholesterol in the blood (dyslipidemia).
  4. Side effects caused by medicines, especially steroids (drug-induced/steroid).
  5. Post-operative complications.
  6. Viral infections, such as mumps.
  7. Genetic conditions (hereditary pancreatitis).
  8. Post-traumatic complications.
  9. Complications following ERCP.

Chronic Pancreatitis

Possible causes include:

  1. Repeated episodes of acute pancreatitis.
  2. Long-term heavy alcohol use (alcoholic pancreatitis).
  3. Smoking.
  4. Cystic fibrosis.
  5. Autoimmune disease.
  6. Blockage of the pancreatic duct caused by stones, infection, or tumors.
  7. Congenital abnormalities of the pancreatic duct (pancreatic ductal anomaly).
  8. Certain viral infections, such as mumps.

Symptoms of Pancreatitis

Acute Pancreatitis

Symptoms may include:

  1. Severe abdominal pain, usually beginning in the upper abdomen and then spreading throughout the abdomen.
  2. Nausea and vomiting.
  3. Low blood pressure due to fluid loss.
  4. High blood pressure that may have elevated due to severe pain.
  5. Abdominal bloating and a feeling of hardness (distended/tense, tender abdomen).
  6. Fever.
  7. Jaundice.
  8. Shock, in severe cases.

Chronic Pancreatitis

Symptoms may include:

  1. Post-acute pancreatitis.
  2. Chronic pancreatitis from the beginning.
  3. Repeated episodes of severe abdominal pain.
  4. Pain that spreads to the back.
  5. Diabetes, which may become difficult to control.
  6. Indigestion (steatorrhea).
  7. Mucus or fatty material in the stool.
  8. Significant or unexplained weight loss.

Tests for Pancreatitis

Acute Pancreatitis

1. Blood Tests

  • Complete blood count (CBC).
  • Serum amylase and lipase.
  • Serum electrolytes.
  • Blood sugar/glucose.
  • Calcium.
  • Lipid profile.
  • Renal profile, e.g. blood urea/S. Creatinine.

2. Imaging

  • Abdominal ultrasound.
  • Abdominal X-ray.
  • CT scan.

Chronic Pancreatitis

1. Blood Tests

  • CBC.
  • Serum amylase and lipase.
  • Liver function tests.
  • Blood sugar/glucose.
  • CA 19-9 when pancreatic cancer is suspected.

2. Imaging

  • Abdominal ultrasound.
  • Abdominal X-ray.
  • CT scan.
  • MRCP.

Treatment of Pancreatitis

Acute Pancreatitis

Treatment may include:

  1. Requires urgent hospital admission (usually to a hospital with an ICU).
  2. IV fluids.
  3. Pain-relieving medicines (analgesics).
  4. Antibiotics only when there is an appropriate indication, such as a confirmed or strongly suspected infection.
  5. Nutritional support and other supportive treatments.
  6. Intensive care support in severe cases. If a bile duct stone is causing obstruction or infection, ERCP may be required to remove the stone (ERCP and stone extraction).
  7. Cholecystectomy (gallbladder removal) is often recommended after recovery from gallstone-related pancreatitis to reduce the risk of another attack.

Chronic Pancreatitis

Treatment may include:

  • Pain-relieving medicines (analgesics).
  • Pancreatic enzyme replacement therapy.
  • Nutritional support.
  • Diabetes management/control.
  • Surgery for Chronic Pancreatitis:
    • Removal of pancreatic stones (pancreatolithotomy).
    • Pancreatic resection, if necessary.

Complications of Pancreatitis

  • Many people with mild or moderate pancreatitis recover with appropriate medical treatment.
  • Severe pancreatitis occurs in a smaller proportion of patients (10%) and can be life-threatening.
  • Fluid accumulation in the lungs (pleural effusion).
  • Life-threatening complications such as septicemia, shock, or multi-organ failure.
  • Acute necrotizing pancreatitis.
  • Pancreatic pseudocyst.
  • Pancreatic abscess.
  • Chronic pancreatitis:
    • Pancreatic cancer.
    • Pancreatic insufficiency.
    • Jaundice (if the bile duct is involved it can cause obstructive jaundice).

Prevention of Pancreatitis

  • Treat gallstones and bile duct stones appropriately.
  • Avoid alcohol completely.
  • Do not smoke.
  • Control abnormal blood lipid levels (dyslipidemia) and diabetes.
  • Avoid excessive fatty and fried foods.
  • Maintain a healthy body weight.
  • If a medicine is known to cause pancreatitis in an individual, discuss alternatives with a doctor rather than stopping prescribed medicine on your own.

Conclusion

  • Acute pancreatitis can be a serious and life-threatening condition and may cause deaths in 10–15% of those affected by it.
  • Taking appropriate preventive measures can reduce the risk of pancreatitis.
  • Early diagnosis and proper treatment can save lives.
  • Chronic pancreatitis may occur together with pancreatic stones and can increase the risk of pancreatic cancer. Therefore proper treatment is necessary.
  • Severe or complicated pancreatitis may require treatment by experienced specialists and surgeons in a specialized hospital.
