title: Ex vivo comparison study of smart Shooter®, a new endoscopic device for safe and speedy treatment.
abstract: BACKGROUND
  In many endoscopic procedures, the operative view can be compromised when manipulating the treatment device because the endoscopists must release their hand from the endoscope. We have developed a new device called the Smart Shooter® (SS) for simultaneous manipulation of the endoscope and treatment device, and evaluated the utility of the SS compared with the conventional method.
  
  
  METHODS
  The SS is a semirigid, loop-shaped channel extender that enables endoscopists to manipulate the treatment device with the thumb of the right hand while holding the endoscope with the same hand. We conducted a comparative study of gastric endoscopic submucosal dissection (ESD) and esophageal injection sclerotherapy (EIS) in a porcine model to compare the utility of the SS method with the conventional method.
  
  
  RESULTS
  In gastric ESD, all lesions were resected en bloc with no perforation. The mean operative time was significantly shorter with the SS method than with the conventional method (287.5 ± 155.4 vs. 403.5 ± 215.6 s, p = 0.04). In esophageal EIS, 4 paravenous injections were given with the SS method and 5 were given using the conventional method. Similarly, the mean operative time was significantly shorter with the SS method than with the conventional method (19.0 ± 7.8 vs. 23.8 ± 10.0 s, p = 0.04).
  
  
  CONCLUSIONS
  Use of the SS enabled a shorter operative time for gastric ESD and esophageal EIS with no adverse events. The present results suggest that the SS can contribute to safe and speedy endoscopic treatment.
