Abstract
Objectives: For safe and speedy colorectal endoscopic submucosal dissection (ESD), it is desirable that the endoscopist operates the endoscope and treatment device simultaneously. We developed a new device, named Smart Shooter® (SS), and introduced it for colorectal ESD. Methods: SS is a loop-shaped channel extender that allows the endoscopist to operate the endoscope with the right hand while manipulating a treatment device with the right thumb. During a 1-year period after introduction of SS, colorectal ESD using SS was performed on 13 consecutive patients by a single endoscopist. The outcome of these patients were compared with that of 13 consecutive patients treated by the conventional technique before introduction of SS, with respect to treatment-related factors. Results: All patients in the SS and conventional groups were treated by en bloc resection, with no serious complications. The use of SS reduced the procedure time from 84.1 to 67.5 min and improved the dissection speed from 16.4 to 20.7 mm2/min, although. Before introduction of SS the clinical path was adhered to by 61.5% (8/13) patients. After introduction all patients (13/13) adhered to the clinical path. Conclusion: SS may contribute to safe and speedy colorectal ESD.
