Abstract

Background & Aims: Endoscopic screening of the colon with available instruments requires considerable training, is often painful, and carries a risk of perforation. New instrument platforms for endoscopic screening could be useful. The aim of this study was to evaluate the extent of colonic intubation by using a novel self-propelled, self-navigating endoscope (the Aer-O-Scope; GI View Ltd, Ramat Gan, Israel). Methods: Twelve young healthy volunteers underwent complete bowel preparation followed by a nonsedated examination using the novel device. Each examination was followed by a standard colonoscopy for safety evaluation. Cecal intubation was confirmed by endoscopic landmarks and fluoroscopy. Results: In 10 out of 12 subjects (83%) the cecum was successfully reached, whereas in 2 cases the Aer-O-Scope advanced to the hepatic flexure. The time to complete advancement to cecum averaged 14.0 ± 7 minutes, and the driving pressures averaged 34 ± 2.3 milibar. Two subjects requested analgesics during the procedures (in both cases the cecum was reached). Four subjects experienced sweating and a bloating sensation that resolved spontaneously. All subjects were followed up to 48 hours and then for 30 days postprocedure, and no complications were observed. Conclusions: In a preliminary pilot feasibility study of this new instrument, the Aer-O-Scope effectively intubated all or most of the colon. Further clinical studies are warranted.
