Chronic Pancreatitis
Pancreatic Insufficiency — inadequate enzyme production → malabsorption, steatorrhoea, weight loss; caused by chronic pancreatitis, cystic fibrosis, or pancreatic cancer
What our notes say
- Pancreatic Insufficiency — inadequate enzyme production → malabsorption, steatorrhoea, weight loss; caused by chronic pancreatitis, cystic fibrosis, or pancreatic cancer (CRUSH COURSE (PART 2) Clinical Chem Patho)
- Chronic pancreatitis is characterized by progressive fibrosis and destruction of pancreatic parenchyma, most commonly from chronic alcohol abuse. (Pancreatic Disorders: A Comprehensive Review)
- Chronic pancreatitis/haemochromatosis — destroys islet cells (Renal, Liver, Cardiac & Adrenal Function Tests for Year 3)
- Malabsorption (coeliac disease, Crohn's, chronic pancreatitis) (CRASH COURSE PART 3 CHEMICAL PATHO)
- Chronic Pancreatitis — progressive permanent damage; cause: chronic alcohol use or genetic. (CRUSH COURSE (PART 2) Clinical Chem Patho)
- Suggests chronic pancreatitis (lipase deficiency) or bile salt malabsorption from small bowel disease. (Gastrointestinal System: Symptoms, Diseases, & VINDICATE Guide)

Practice questions on Chronic Pancreatitis
In acute pancreatitis, which histological finding distinguishes it from chronic pancreatitis?
- Extensive parenchymal fibrosis
- Neutrophilic inflammation and enzymatic fat necrosis
- Atrophy of acini
- Ductal squamous metaplasia
Answer: B. Acute pancreatitis is characterized by edema, proteolysis, fat necrosis, and acute inflammation (neutrophils). Chronic pancreatitis is defined by irreversible fibrosis and atrophy. ---
A patient with chronic pancreatitis develops steatorrhea. What is the underlying mechanism?
- Excessive bile acid production
- Loss of >90% of exocrine pancreatic function
- Insulin resistance
- Bacterial overgrowth in the ileum
Answer: B. Steatorrhea and malabsorption occur only when exocrine secretion (lipase, etc.) falls below 10% of normal levels due to parenchymal destruction. ---
A 45-year-old male with chronic pancreatitis experiences steatorrhea (fatty stools) and weight loss. What is the most likely cause of these symptoms?
- Malabsorption due to exocrine pancreatic insufficiency
- Bacterial overgrowth in the small intestine
- Celiac disease
- Short bowel syndrome
Answer: A. Chronic pancreatitis leads to destruction of the exocrine pancreas, impairing the production of digestive enzymes. This results in malabsorption of fats, proteins, and carbohydrates, leading to steatorrhea and weight loss. ---
A 60-year-old male presents with painless jaundice, dark urine, and pale stools. He has a history of chronic pancreatitis. Which diagnostic modality is most likely to identify the cause of his jaundice?
- Abdominal ultrasound
- CT scan of the abdomen
- Endoscopic retrograde cholangiopancreatography (ERCP)
- Liver biopsy
Answer: C. Given the history of chronic pancreatitis, a pancreatic head mass causing biliary obstruction is highly suspected. ERCP allows for visualization and potential intervention (like stenting) of the biliary tree and can also identify pancreatic ductal abnormalities. ---
In acute pancreatitis, which histological finding distinguishes it from chronic pancreatitis?
- Presence of fibrosis
- Necrotic acini with preservation of ducts
- Atrophy of islets of Langerhans
- Protein plugs in ducts
Answer: B. Acute pancreatitis shows necrotic acini but ducts are characteristically preserved. Chronic pancreatitis shows fibrosis and protein plugs. ---
A patient with chronic pancreatitis develops steatorrhea and weight loss. What is the underlying mechanism?
- Destruction of islets of Langerhans
- Loss of exocrine acinar tissue causing enzyme deficiency
- Obstruction of the common bile duct
- Autoimmune destruction of mucosal cells
Answer: B. Destruction of acinar tissue reduces lipase production, causing fat malabsorption and steatorrhea. ---
