Different endoscopic resection techniques should be adopted for gastric submucosal tumors in different area.

<p>For tumors located in the circular area around cardia, although ESE can be performed in a retroflexed fashion, we still recommend transcardiac submucosal tunneling technique in a direct view. For tumors in distal fundus or lesser curvature, ESE in a retroflexed fashion is the only choice. For tumors located in most areas of gastric body, both ESE and STER are suitable.
