Management of paediatric ulcerative colitis, part 1: Ambulatory care—An updated evidence-based consensus guideline from the European Society of Paediatric Gastroenterology, Hepatology and Nutrition and the European Crohn's and Colitis Organisation

Objectives: Despite advances in the management of ambulatory paediatric ulcerative colitis (UC), challenges remain as many patients are refractory to therapy and some require colectomy. The aim of these guidelines is to provide an update on optimal care for UC through detailed recommendations and practice points. Methods: These guidelines are an update to those published in 2018 and are a joint effort of the Paediatric IBD Porto group of European Society of Paediatric Gastroenterology, Hepatology and Nutrition and the European Crohn's and Colitis Organisation. An extensive literature search with subsequent evidence appraisal using the Oxford methodology was performed, followed by three online voting sessions and a consensus face-to-face meeting. Thirty-nine recommendations and 77 practice points were endorsed by the 25 experts with at least an 84% consensus rate. Results: Robust evidence-based recommendations and detailed practice points are provided. In addition to reemphasising and updating the role of more ‘traditional’ UC therapies, these guidelines outline optimising the use of antitumour necrosis factor therapies and integrating newer biologics and small molecules, as well as supportive therapy, to improve outcomes and provide an updated management algorithm. Measurement and monitoring tools and decision aids are provided, and additional aspects, including nutritional support, extraintestinal manifestations, pouchitis, inflammatory bowel disease-unclassified and patient support, are discussed. Some aspects, including surgery and thromboprophylaxis, are covered in the acute severe UC guidelines. Conclusions: These guidelines serve as an aid in managing children with UC through a combination of evidence-based recommendations and more practical practice points in the ambulatory setting.
