What is acute pancreatitis?
Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or remote organ systems.
What are the most common causes of acute pancreatitis?
Gallstones, alcohol consumption, hypertriglyceridemia, hypercalcemia, infections, trauma, and certain drugs.
What is the initial step in the pathogenesis of acute pancreatitis?
Conversion of trypsinogen to trypsin within acinar cells, leading to autodigestion of the pancreas.
What are the common clinical features of acute pancreatitis?
Severe epigastric pain, nausea, vomiting, fever, jaundice, and radiating pain to the back.
What is Grey Turner’s sign?
Ecchymosis in one or both flanks, indicating retroperitoneal hemorrhage in severe pancreatitis.
What is Cullen’s sign?
Periumbilical ecchymosis, suggesting hemorrhagic pancreatitis.
How is acute pancreatitis diagnosed?
Presence of two of the three criteria: epigastric pain, serum amylase or lipase >3 times normal, and imaging findings.
Which imaging modality is preferred for diagnosing acute pancreatitis?
Contrast-enhanced CT scan or MRI.
What laboratory tests are commonly used in acute pancreatitis diagnosis?
Serum amylase, lipase, full blood count, electrolytes, urea, creatinine, calcium, phosphate, and lipid profile.
What is the role of ERCP in pancreatitis?
Used in suspected biliary pancreatitis, especially in cases of obstructive jaundice or cholangitis.
What is the most important treatment for acute pancreatitis?
Aggressive intravenous fluid resuscitation and supportive care.
Why is the patient kept nil per oral (NPO) in acute pancreatitis?
To rest the pancreas and reduce enzyme secretion.
What is the role of narcotic analgesics in pancreatitis?
Used to control severe abdominal pain.
When are antibiotics indicated in acute pancreatitis?
Only in cases of infected pancreatic necrosis or sepsis.
What is the prognosis of acute pancreatitis?
85-90% of cases are self-limited and resolve within 3-7 days with proper management.
What are complications of acute pancreatitis?
Pseudocysts, necrosis, infection, pancreatic abscess, and organ failure.
What is chronic pancreatitis?
A disease process characterized by irreversible damage to the pancreas, leading to progressive loss of function.
What are the major causes of chronic pancreatitis?
Chronic alcohol use, tobacco use, genetic factors, autoimmune pancreatitis, and recurrent acute pancreatitis.
What are the cardinal symptoms of chronic pancreatitis?
Abdominal pain, maldigestion, weight loss, and diabetes mellitus.
How does abdominal pain present in chronic pancreatitis?
Pain is variable in severity, may be constant or intermittent, and is worsened by eating.
What is steatorrhea?
Bulky, foul-smelling stools with fat droplets due to fat malabsorption in chronic pancreatitis.
How is chronic pancreatitis diagnosed?
Based on clinical features, imaging (CT, MRI, or ERCP), and pancreatic function tests.
What is the cornerstone of treatment for steatorrhea in chronic pancreatitis?
Pancreatic enzyme replacement therapy (PERT).
How is pain managed in chronic pancreatitis?
With analgesics, lifestyle modifications, and sometimes endoscopic or surgical interventions.
