This narrative review represents the consensus output of SIGENP's thematic working groups (WGs) in key fields-inflammatory bowel disease (IBD), Gastrointestinal Endoscopy, Hepatology, Nutrition and Intestinal Failure, Functional and Motility Disorders, and Allergy and Immunity. Each WG conducted a focused review of recent literature, national activities, and registry data, identifying unmet needs and defining strategic objectives. Draft reports were refined through plenary discussions and finalized by consensus during dedicated SIGENP meetings. Across all areas, shared priorities emerged: advancing precision and personalized medicine, integrating multi-omics and digital tools, and promoting pediatric-specific evidence through multicenter collaboration and harmonized registries. Disease-specific gaps include early diagnosis and biomarker discovery in IBD and liver disease, standardization of pediatric endoscopy and motility diagnostics, optimization of nutritional interventions and intestinal failure management, and the exploration of organoid and immune models in celiac disease and food allergy.
