Endoscopic mucosal resection for early cardia cancer by minimum laparotomy

Endoscopic mucosal resection (EMR) has been widely accepted as a minimally invasive and standard treatment for early gastric cancers without ulceration or signs of submucosal invasion and meeting the criteria for diameter, macroscopic appearance, and well- or moderately differentiated histology. However, EMR cannot be applied to some cases owing to technical difficulties relating to the intragastric location of the cancers even when the above criteria are satisfied. We report here a new approach to EMR for early cancers of the cardia located close to the esophagocardia junction that are outside the indications for ordinary EMR.
