Barrett’s oesophagus is the precursor to oesophageal adenocarcinoma, which carries a poor prognosis,1 and it is likely that all endoscopists and gastroenterologists will encounter Barrett’s oesophagus in their clinical practice.
Careful assessment and management of patients who have Barrett’s oesophagus with endoscopic surveillance and endoscopic endotherapy aim to reduce the risk of progression to invasive adenocarcinoma. Advances in endoscopic diagnosis and therapy should, therefore, help to reduce the risk of progression. As with all premalignant conditions and surveillance programmes,2 careful multidisciplinary management of the patient is important to reduce the risk of causing them to become unduly concerned. Here, we present some mistakes that in our experience are commonly made in the endoscopic diagnosis and management of Barrett’s oesophagus and give advice on how to avoid them.
