title: Deep enteroscopy with standard endoscopes using a novel through-the-scope balloon.
abstract: OBJECTIVE
  A new on-demand enteroscopy (ODE) device has been designed to allow deep enteroscopy using a standard adult colonoscope with the aid of a novel through-the-scope balloon. The aims of the current study were to establish the feasibility, efficacy, and safety of ODE in performing anterograde and retrograde enteroscopy.
  
  
  METHODS
  A retrospective, single-center study of 28 consecutive deep ODE procedures (11 anterograde and 17 retrograde) was performed. Diagnostic yield, therapeutic yield, technical success, procedure time, depth of maximal insertion (DMI), time to DMI, and adverse events were recorded.
  
  
  RESULTS
  The mean diagnostic and therapeutic yields were 45 % and 36 % for anterograde enteroscopy and 59 % and 47 % for retrograde enteroscopy, respectively. Technical success was achieved in 100 %. For anterograde enteroscopy, the mean total procedure time was 24 minutes, with a mean DMI of 1.2 m. For retrograde enteroscopy, the mean total procedure time was 31 minutes, with a mean DMI of 1.1 m. No adverse events were recorded.
  
  
  CONCLUSIONS
  Deep enteroscopy using a novel through-the-scope balloon and standard endoscope appeared to be feasible and safe, with rapid procedures times.
