Double-snare resection technique: a new approach for treating rectal carcinoid tumors

Endoscopic resection is the preferred treatment for rectal carcinoid tumors (NETs), with different techniques described in the literature. Endoscopic mucosal resection (EMR) is feasible and is associated with a low risk of adverse events but a significant risk for incomplete resection [1]. Advanced endoscopy resection techniques have better success in achieving R0 resections but are associated with a higher risk of adverse events, are time consuming, and require highly skilled endoscopists to perform them [2] [3] [4] [5]. We describe a new resection technique for rectal NETs <20 mm in diameter, the double-snare resection (DSR) technique, which may potentially overcome the aforementioned disadvantages.
