Battle of the scopes: which endoscopic technique removes rectal tumors best?
NCT ID NCT07612748
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks back at 483 patients who had small rectal neuroendocrine tumors (less than 2 cm) removed using one of two endoscopic techniques: endoscopic submucosal dissection (ESD) or endoscopic partial muscle resection (EPMR). The goal is to compare how often each method leaves cancer cells at the edge of the removed tissue (positive margin), along with other outcomes like procedure time and complications. The findings may help doctors choose the safer, more effective approach for these tumors.
