Anchoring the snare tip is a feasible endoscopic mucosal resection method for small rectal neuroendocrine tumors

Abstract Small rectal neuroendocrine tumors (NETs) can be treated using cap-assisted endoscopic mucosal resection (EMR-C), which requires additional effort to apply a dedicated cap and snare. We aimed to evaluate the feasibility of a simpler modified endoscopic mucosal resection (EMR) technique, so-...
