[Chronic pancreatitis: new definition and perspectives.]

Area of Science:

• Gastroenterology
• Pathology

Background:

• Traditionally viewed as solely alcohol-induced, chronic pancreatitis is now recognized as a complex fibroinflammatory condition.
• Evolving concepts acknowledge multiple etiologies including toxic-metabolic, genetic, immunologic, and obstructive factors.

Purpose of the Study:

• To review the impact of the new concept of chronic pancreatitis on understanding its pathogenesis.
• To describe peculiar forms of chronic pancreatitis and their distinct clinical, imaging, prognostic, and therapeutic features.
• To outline the implications for clinical and therapeutic approaches to chronic pancreatitis.

Main Methods:

• Literature review of recent advancements in chronic pancreatitis research.
• Synthesis of current understanding regarding the pathogenesis of chronic pancreatitis.
• Analysis of distinct clinical presentations and management strategies for specific chronic pancreatitis subtypes.

Main Results:

• Chronic pancreatitis is a multifactorial fibroinflammatory disease, moving beyond the single-cause alcohol-induced model.
• Identification of specific chronic pancreatitis forms, including autoimmune, paraduodenal, and those linked to gene mutations, with unique characteristics.
• The new conceptualization significantly impacts the comprehension of disease mechanisms and guides tailored therapeutic interventions.

Conclusions:

• The paradigm shift in understanding chronic pancreatitis as a multifactorial disease has refined its pathogenesis comprehension.
• Distinct subtypes of chronic pancreatitis necessitate specialized diagnostic and therapeutic strategies.
• This evolving concept is crucial for advancing the clinical and therapeutic management of chronic pancreatitis.
