Colonoscopy Using Motorized Spiral Enteroscope

Completed

• Conditions: Colon Disease

• Registration Number: NCT04895254
• Lead Sponsor: St. Antonius Hospital

Brief Summary

The new technology of the motorized Spiral enteroscope, originally developed for deep small bowel enteroscopy, might potentially overcome some limitations of standard colonoscopy.

Detailed Description

Cecal intubation rate represents a key procedural quality parameter in diagnostic colonoscopy. However, even in experienced hands, a significant percentage of colonoscopies (1.6-16.7%) remain incomplete because of a failure to intubate the cecum. The new technology of the motorized Spiral enteroscope, originally developed for deep small bowel enteroscopy, might potentially overcome some limitations of standard colonoscopy. The study aim was to evaluate the feasibility and safety of motorized Spiral enteroscopy for difficult colonoscopies.
