Chronic Pancreatitis (CP)

Chronic pancreatitis is progressive inflammation and fibrosis of the pancreas that leads to irreversible structural damage, chronic abdominal pain, pancreatic exocrine insufficiency (PEI), and diabetes. Early diagnosis and comprehensive management can reduce complications and hospitalizations.

Causes & Risk Factors

• Alcohol abuse (leading cause in adults)
• Smoking (accelerates progression)
• Genetic mutations (PRSS1, SPINK1, CFTR, CTRC)
• Recurrent acute pancreatitis, hypertriglyceridemia, hypercalcemia
• Autoimmune pancreatitis
• Obstructive causes (pancreatic divisum, tumors)
• Idiopathic (no identifiable cause)

Symptoms

• Recurrent or persistent epigastric pain radiating to the back
• Pain worsens after meals or alcohol
• Weight loss, malnutrition
• Steatorrhea (greasy, foul-smelling stools) from PEI
• Diabetes (type 3c)
• Nausea, vomiting, bloating

Diagnosis

• History of recurrent pancreatitis and risk factors
• Imaging: CT, MRI/MRCP, endoscopic ultrasound (EUS) showing calcifications, ductal irregularities, atrophy
• Functional tests: fecal elastase w150μg/g indicates PEI
• Labs: pancreatic enzymes may be normal in CP; monitor glucose, fat-soluble vitamins, bone density
• Rule out pancreatic cancer in new-onset CP with atypical features

Treatment & Management

Lifestyle

• Absolute alcohol cessation and smoking cessation
• Small, frequent low-fat meals; consider medium-chain triglycerides
• Adequate hydration, vitamin supplementation

Pain Control (stepwise)

• Acetaminophen, NSAIDs → weak opioids → strong opioids (use cautiously)
• Adjuvant agents: pregabalin, duloxetine, tricyclics
• Pancreatic enzyme replacement therapy (PERT) may reduce pain by feedback inhibition
• Antioxidant therapy (selenium, vitamin C/E, methionine) has mixed evidence

Pancreatic Enzyme Replacement Therapy (PERT)

• Enteric-coated lipase formulations taken with meals/snacks
• Titrate dose based on stool consistency and weight gain/loss

Endoscopic & Surgical Options

• ERCP with sphincterotomy/stenting for ductal strictures or stones
• Extracorporeal shock wave lithotripsy (ESWL) for calcific disease
• Surgical drainage (Puestow) or resection (Whipple, Frey) for select patients
• Total pancreatectomy with islet autotransplant for refractory pain/quality-of-life issues

Endocrine Management

• Monitor HbA1c; treat pancreatogenic diabetes with insulin (risk of hypoglycemia due to glucagon deficiency)
• Nutritional counseling for balanced carb intake

Living with Chronic Pancreatitis

• Track pain scores, diet, weight, enzyme doses, blood sugars, and triggers
• Work with a multidisciplinary team (GI, endocrinology, nutrition, pain management, mental health)
• Address anxiety/depression—chronic pain is draining
• Plan flare strategies (hydration, low-fat diet, medication adjustments)

Complications

• Exocrine pancreatic insufficiency and malnutrition
• Diabetes mellitus (type 3c)
• Pseudocysts, biliary obstruction, duodenal obstruction
• Pancreatic cancer risk (especially after >20 years or with hereditary CP)
• Osteoporosis from malabsorption

Research & Future Directions

Investigations focus on stem cell regeneration, antifibrotic agents, nerve-targeted pain therapies, and biomarkers predicting progression to cancer.

Experimental & Emerging Treatments

• Peripherally Acting μ-Opioid Receptor Antagonists: Reduce opioid-induced GI side effects while sparing analgesia.
• Nerve Growth Factor (NGF) Inhibitors: Target pancreatic neuropathy to decrease pain (in trials).
• Endoscopic Neurolysis & Nerve Stimulation: Minimally invasive techniques to block pain pathways.
• Islet Organoids & Beta-Cell Replacement: Aim to restore endocrine function after pancreatectomy.
