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.
Dr Nadir Arber and colleagues evaluated the extent of colonic intubation by using a novel self-propelled, self-navigating endoscope, the Aer-O-Scope.
The researchers had 12 young healthy volunteers undergo 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.
The researchers found that in 83% of subjects, the cecum was successfully reached.
|Advancement to cecum averaged 14 minutes, and the driving pressures averaged 34 milibar|
In the remaining cases, the team noted that the Aer-O-Scope advanced to the hepatic flexure.
The time to complete advancement to cecum averaged 14 minutes, and the driving pressures averaged 34 milibar.
The team reported that 2 subjects requested analgesics during the procedures, and in both cases the cecum was reached.
A further 4 subjects experienced sweating and a bloating sensation that resolved spontaneously.
The researchers followed up all subjects to 48 hours and then for 30 days postprocedure, and observed no complications.
Dr Arber's team concluded, “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.”
