Expert consensus on diagnostic guidelines for pediatric inflammatory bowel disease in Japan

Area of Science:

• Pediatric Gastroenterology
• Inflammatory Bowel Disease Research

Background:

• Pediatric inflammatory bowel disease (IBD) often presents with atypical symptoms and a more severe course compared to adults.
• Recognizing age-specific differences in IBD presentation, diagnosis, and evaluation is crucial for children.
• The European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) revised Porto criteria (2014) are globally utilized for pediatric IBD diagnosis.

Purpose of the Study:

• To support the development of formal diagnostic guidelines for pediatric IBD in Japan.
• To summarize key diagnostic considerations and clinical practices for pediatric IBD within the Japanese context.

Main Methods:

• A review synthesizing international diagnostic guidelines for IBD.
• Incorporation of expert opinions from Japanese pediatric gastroenterologists.
• Outline of essential clinical and laboratory evaluations, treatment, and follow-up strategies.

Main Results:

• Summarized recommended diagnostic tests for children with suspected IBD.
• Highlighted critical clinical points requiring special attention in pediatric IBD.
• Reflected a blend of global standards and domestic clinical experience in Japan.

Conclusions:

• This review provides practical information for diagnosing and managing pediatric IBD in Japan.
• It aims to guide physicians and patients, despite not establishing formal diagnostic criteria or evidence levels.
