Abstract: The incidence of adenocarcinoma of the esophagogastric junction (AEG) has been increasing worldwide, which attracts great attention among medical professionals because of its anatomical location and unique biological behavior. Although some consensus has been reached regarding the pathogenesis and classification of AEG, there remain debates about its surgical treatment, including the surgical route, scope of gastrectomy, range of lymph node dissection, and digestive tract reconstruction. These debates limit the exploration and development of AEG treatment and make it difficult to standardize the diagnosis and treatment of AEG. This study reviews the relevant literature on AEG in recent years and comprehensively discusses the current consensus and controversy regarding the treatment of AEG with the aim to provide a more reasonable and effective method for its clinical diagnosis and treatment.
