Design outcomes

Primary

MeasureTime frame
The difficulty technique of colonoscopy between water-assisted colonoscopy and carbon dioxide colonoscopy in beginner 2 months after the end of intervention Cecal intubation time

Secondary

MeasureTime frame
Rate of easy intubation 2 months after the end of intervention cecal intubation time within 10 minutes,Rate of technical failure 2 months after the end of intervention cecal intubation time more than 20 minutes,Total procedure time 2 month after the end of intervention Total procedure time is recorded from cecal intubation time and withdrawal time.,Cecal intubation success rate 2 months after intervention the rate of success colonoscopy by cecal intubation,Adenoma detection rate 2 months after intervention During withdrawal phase, Record polyps are recorded ,Cleanliness of bowel preparation 2 months after the end of intervetion Cleanliness of bowel preparation by Boston bowel preparation scale,Amount of analgesic drug 2 month after the end of interventio Total fentanyl administration during colonoscopy,Number of times patient's position change 2 months after intervention Record number of times patient's position change due to difficult to insert colonoscope. This is depended on colonoscopist decision to change patient's position., Complication of colonoscopy 2 month after the end of intervention Complication during colonoscopy and 24 hour after colonoscopy, Data is record by endoscopist or nurse.,Difficulty score by colonoscopist 2 month after the end of intervention Colonoscopists reported outcome using a questionnaire interview
