Water Exchange Versus Carbon Dioxide for Colonoscopy
2014年2月11日 更新者：Sorlandet Hospital HF
Water Exchange Versus Carbon Dioxide Insufflation to Improve Colonoscopy Screening - a Randomized Controlled Trial
Colonoscopy is commonly used in screening for colorectal cancer.
A refined technique of colonoscopy involving the use of water as the sole modality to aid colonoscope insertion, water exchange, has been described in recent research papers to decrease patient discomfort and pain, and to reduce the need for sedation during colonoscopy when compared with standard air insufflation.
Carbon dioxide insufflation has been described to decrease patient discomfort after colonoscopy.
No randomized trial has so far compared the use of water exchange to carbon dioxide insufflation.
Our hypothesis is that water exchange inflicts less discomfort to patients undergoing colonoscopy than carbon dioxide insufflation.
Patients undergoing screening colonoscopy in two centers in Norway, one center in Poland and one center in The Netherlands will be enrolled and randomized to examination of either of the two methods.

実験的：Water exchange
Colonoscopy with water exchange as the sole modality to reach the cecum.
Carbon dioxide can be used in case of intubation failure with the test method.
|
Water is infused and suctioned in a systematic fashion to obtain luminal view and for cleansing of the colon to facilitate colonoscope insertion.
The carbon dioxide pump is turned off, only to be turned on during withdrawal from the cecum.
