Chronic pancreatitis is a progressive fibroinflammatory disease that exists in 2 forms:
- large-duct forms (often with intraductal calculi)
- small-duct form
Causes of chronic pancreatitis
Chronic pancreatitis results from a complex mix of:
- environmental factors - alcohol, cigarettes, and occupational chemicals
- genetic factors - mutation in a trypsin-controlling gene or the cystic fibrosis transmembrane conductance regulator (CFTR)
- a few patients have hereditary or autoimmune disease
Management of pain
Pain is the main symptom that occurs in two forms:
- recurrent attacks of pancreatitis (representing paralysis of apical exocytosis in acinar cells)
- constant and disabling pain
Management of the pain is mainly empirical, involving:
- potent analgesics
- duct drainage by endoscopic or surgical means
- partial or total pancreatectomy
- steroids rapidly reduce symptoms in patients with autoimmune pancreatitis
- micronutrient therapy to correct electrophilic stress is emerging as a promising treatment
Steatorrhoea, diabetes, local complications, and psychosocial issues associated are additional therapeutic challenges.
