ES Dellon et al. Clin Gastroenterol Hepatol 2022; 20: 2474-2484. Open Access! International Consensus Recommendations for Eosinophilic Gastrointestinal Disease Nomenclature

This article has 91 authors! Using Delphi surveys, the authors recommend the following:

• “EGID” was the preferred umbrella term for disorders of gastrointestinal (GI) tract eosinophilic inflammation in the absence of secondary causes
• Involved GI tract segments will be named specifically and use an “Eo” abbreviation convention: eosinophilic gastritis (now abbreviated EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC)
• For EoN, “it is desirable, but not required, to name specific locations of small bowel involvement, if these are known…The abbreviation for eosinophilic duodenitis should be “EoD”… for eosinophilic jejunitis should be “EoJ”….eosinophilic ileitis should be “EoI”
• The term “eosinophilic gastroenteritis” is no longer preferred as the overall name (but can be used to indicate involvement of both the stomach and small bowel)
• When >2 GI tract areas are involved, the name should reflect all of the involved areas
