In our hospital, a 64-year-old man was referred with a diagnosis of a 0-IIa 4.5 cm intramucosal cancer at the posterior wall of the lower part of the gastric body (Fig. 1A). IT-2 Knife and Hook-Knife (Olympus, Tokyo, Japan) were mainly used (Fig. 1B). The histology of the en bloc dissected specimen revealed a well differentiated intramucosal-type cancer with negative vertical and horizontal margins with no lymphovascular infiltration (Fig. 1C).
