Proposal for a new grading system for chronic pancreatitis: the ABC system

Area of Science:

• Gastroenterology
• Clinical Medicine

Background:

• Current chronic pancreatitis classification systems lack universal applicability.
• Existing methods rely on histology or imaging, which may not always be available or correlate with clinical symptoms.
• Therapeutic decisions for chronic pancreatitis are primarily guided by clinical presentation rather than solely ductal morphology or histology.

Purpose of the Study:

• To propose a comprehensive staging system for all types of chronic pancreatitis.
• To facilitate comparison between patient groups with similar disease characteristics.
• To provide therapeutic guidelines integrated with the staging system.

Main Methods:

• Development of a novel staging system for chronic pancreatitis.
• Categorization of patients into grades A, B, and C based on the presence of abdominal pain and complications.
• Further stratification based on pancreatic exocrine and endocrine function deficiency.

Main Results:

• The proposed system classifies chronic pancreatitis patients into distinct grades.
• The staging system incorporates clinical presentation (pain, complications) and functional deficiency.
• It allows for a more accurate description of the disease state.

Conclusions:

• The new staging system is applicable to all diagnosed chronic pancreatitis cases.
• It offers a relevant framework for therapeutic approaches and prognosis assessment.
• This system enhances the ability to compare patient cohorts and guide treatment.
