Endoscopic submucosal resection of gastric subepithelial lesions smaller than 20Â mm: a comparison of saline solution-assisted snare and cap band mucosectomy techniques

In GSLs smaller than 20 mm, ESMR with saline solution-assisted snare or endoscopic cap band mucosectomy techniques is safe, the adverse event rate is low, accurate diagnosis is achieved, and treatment with en bloc resection is provided in a single session. Given similar success and adverse event rates, saline solution-assisted ESMR may be the preferred technique because of its lower cost advantages.
