The role of artificial intelligence (AI) in the detection of upper gastrointestinal (GI) neoplasia has been emerging in recent years. Dr Wai Leung (University of Hong Kong, China) discussed the latest evidence on AI and the diagnosis, characterisation, risk prediction, and the examination of upper GI neoplasia [1]. A retrospective meta-analysis demonstrated that AI was accurate in detecting gastric neoplastic lesions, with an area under the receiver-operating characteristic curve (AUC) of 0.96, a sensitivity of 0.92, and a specificity of 0.88. For the detection of Barret’s oesophagus neoplasia, the corresponding results were 0.96, 0.88, and 0.90. For squamous oesophagus neoplasia the data showed an AUC of 0.92, a sensitivity of 0.84, and a specificity of 0.90 [2]. In addition, a prospective study including 1,198 patients showed a similar accuracy of endoscopic detection of gastric lesions and neoplasms by AI (0.72) and by expert (0.68). However, the AI mod...
