Experimental: 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.

Aktiver Komparator: Carbon dioxide insufflation
Carbon dioxide insufflation will be used in standard fashion to reach the cecum.
|
Carbon dioxide insufflation to obtain luminal view to facilitate colonoscope insertion, considered to be standard procedure.
