Acute pancreatitis can fully resolve if the cause is removed, unlike chronic pancreatitis which causes permanent damage. Biliary stones often trigger acute pancreatitis by blocking ducts, leading to pancreatic duct hypertension.

Area of Science:

  • Gastroenterology
  • Pancreatology
  • Pathophysiology

Background:

  • Acute pancreatitis may fully resolve if the cause is removed, while chronic pancreatitis leads to irreversible changes.
  • Biliary tract stones are a common cause of acute pancreatitis, potentially leading to pancreatic duct obstruction and hypertension.
  • Experimental data suggests intra-acinar cell digestive enzyme activation by lysosomal hydrolases may play a role in acute pancreatitis.

Purpose of the Study:

  • To summarize the current understanding of acute and chronic pancreatitis pathogenesis.
  • To highlight the role of biliary stones in acute pancreatitis.
  • To discuss potential mechanisms in acute pancreatitis, including enzyme activation.

Main Methods:

  • Literature review and synthesis of existing research on pancreatitis.

  • Analysis of etiological factors for acute and chronic pancreatitis.
  • Discussion of experimental findings related to enzyme activation pathways.

    • Main Results:

    • Complete functional and morphologic restitution of the pancreas is achievable post-acute pancreatitis if the inciting factor is eliminated.
    • Chronic pancreatitis is characterized by irreversible pathological changes.
    • Biliary tract stones are implicated in most acute pancreatitis cases, causing ductal obstruction and hypertension.

    Conclusions:

    • The reversibility of pancreatic damage depends on the type of pancreatitis and removal of the etiological agent.
    • Biliary stone disease is a primary suspect in acute pancreatitis, linked to ductal hypertension.
    • The precise pathogenesis of chronic pancreatitis, despite its association with ethanol abuse, remains largely unknown.
