title: Spiral enteroscopy: a novel method of enteroscopy by using the Endo-Ease Discovery SB overtube and a pediatric colonoscope.
abstract: BACKGROUND
  Pathologic diagnosis and therapeutic interventions on the small bowel have been difficult and challenging for gastroenterologists. In the last few years, significant advances have been made in this direction. New diagnostic and therapeutic modalities for visualizing the small bowel have been introduced. Furthermore, increased indications for small-bowel imaging and therapeutics have been recognized. However, the currently available methods have limitations, and development of newer, rapid, minimally invasive, safe, and readily available techniques is needed.
  
  
  OBJECTIVE
  Our purpose was to evaluate the safety and efficacy of a novel method of spiral enteroscopy using a specialized overtube (Endo-Ease Discovery SB) with a pediatric colonoscope (PCF-140L).
  
  
  METHODS
  Case series.
  
  
  METHODS
  Two international tertiary referral centers.
  
  
  METHODS
  Twenty-seven adult patients with obscure GI bleeding were enrolled in this study.
  
  
  METHODS
  Spiral enteroscopy with the Endo-Ease Discovery SB overtube and a pediatric colonoscope.
  
  
  METHODS
  Depth of insertion, time of procedure, and complications.
  
  
  RESULTS
  Average depth of insertion was 176 cm (range 80-340 cm) from ligament of Treitz, and average time of procedure was 36.5 minutes (range 90-65 minutes). Eleven patients had minor complications, which included minimal mucosal trauma and sore throat.
  
  
  CONCLUSIONS
  Small number of patients with a case series study design.
  
  
  CONCLUSIONS
  Preliminary data suggest that use of Endo-Ease Discovery SB overtube for enteroscopy is a safe and effective technique for visualization of the small bowel.
