The colonoscopy procedure
BLIND
On the colonoscopy day, all patients had the procedure by an experienced gastroenterologist and two trained nurses. The gastroenterologist and the nurses were blind regarding the group of patients. Propofin and etomidate were used as narcotic drugs. A Fuji 600 series scope with a processor model 4050 was utilized. No distal attachments were used during the procedures. Our approach involved the application of Fice chromoendoscopy and the utilization of water/air insufflation. Two trained assistants recorded the total procedure and the intubation time.
