Part 2 will be released on Wednesday, the 29th of April.

Eosinophilic oesophagitis (EoE) is now a well-recognised condition. But it was not always so. In this episode, Prof. Alex Straumann shares how EoE was first identified, taking us back to the late 1980s when unusual cases of food impaction and eosinophilic inflammation did not fit any known diagnosis.

He discusses the clinical observations that led to recognising EoE as a distinct disease, the early case series that defined its phenotype, and the initial treatment approaches that shaped current practice. The episode also addresses key diagnostic challenges that remain relevant today, including the distinction from oesophageal eosinophilia and the limitations of symptom-based assessment.
