Japanese clinical practice guidelines for pancreaticobiliary maljunction

Area of Science:

• Gastroenterology
• Hepatology
• Surgical Oncology

Background:

• No established clinical guidelines existed for pancreaticobiliary maljunction (PBM) management.
• The Japanese Study Group on Pancreaticobiliary Maljunction (JSPBM) and Japan Biliary Association (JBA) initiated guideline development.
• Limited evidence necessitated an expert consensus approach.

Purpose of the Study:

• To establish the first clinical practice guidelines for pancreaticobiliary maljunction (PBM).
• To provide a framework for the diagnosis, management, and treatment of PBM.
• To enhance recognition and understanding of PBM among clinicians.

Main Methods:

• Expert consensus development based on a review of medical literature.
• Consideration of 46 clinical questions covering PBM concepts, pathophysiology, diagnosis, complications, and treatment.
• Inclusion of public comments and expert review in the guideline finalization process.

Main Results:

• Guidelines address PBM with and without biliary dilatation, defining the former in relation to congenital biliary dilatation.
• Comprehensive coverage of PBM, including 10 CQs on concepts/pathophysiology, 10 on diagnosis, 9 on complications, and 17 on treatment/prognosis.
• Statements and comments were prepared for each clinical question.

Conclusions:

• These guidelines offer crucial assistance for the clinical management of pancreaticobiliary maljunction (PBM).
• The focus is on clinical utility and providing essential information for wider PBM recognition.
• The guidelines aim to standardize PBM care and improve patient outcomes.
