Colonoscopy is completed without abdominal compression by GI assistants. Live image of magnetic endoscopic imaging system is shown to investigators for study but not to the colonoscopist for facilitating the intubation process.

Live image of magnetic endoscopic imaging system is shown to investigators for study but not to the colonoscopist for facilitating the intubation process. The colonoscopist directs GI assistants to conduct compression by his subjective judgement.
Colonoscopy is completed with abdominal compression by GI assistants. Live image of magnetic endoscopic imaging system is shown both to investigators for study and to the colonoscopist for facilitating the intubation process. The colonoscopist directs GI assistants to conduct compression according to the guidance of magnetic endoscopic imaging system.
