Endoscopic resection for esophageal or gastroesophageal junction adenocarcinoma

Endoscopic resection is a treatment option for the superficial carcinoma in gastrointestinal tract. The strategy of endoscopic resection for gastric adenocarcinoma (GAC) and esophageal squamous cell carcinoma (ESCC) has been well established in Japan, but not so much for esophageal adenocarcinoma (EAC) (1-3). EAC has become prevalent especially in North America and Western Europe, but it is still uncommon in east Asia (4).
