Lymphocytic oesophagitis: diagnosis and management

Lymphocytic oesophagitis is a rare inflammatory condition that was first described in 2006. Although it is being increasingly diagnosed, it remains poorly described and characterised. There is limited research on the natural history, diagnosis and management of this condition. The most common presenting symptoms are dysphagia, chest pain and heartburn. Endoscopic features can mimic eosinophilic oesophagitis. International consensus is needed to secure a histological definition, to agree on an endoscopic severity scoring system and to determine an appropriate management algorithm. This review summarises the main evidence for the diagnosis and management of lymphocytic oesophagitis, thus setting the scene for the future directions needed to improve the management of this condition.
