Grupa uczestników / Arm |
Interwencja / Leczenie |
|---|---|
|
Aktywny komparator: Carbon dioxide method
Colonoscopy performed as usual, with the minimal CO2 insufflation required to aid insertion and adequate distension during withdrawal for exploration.
Washing allowed as needed.
Considered to be standard procedure.
|
Insufflation with CO2 during insertion and withdrawal phases of colonoscopy.
|
|
Eksperymentalny: Water Exchange-CO2
Insufflation not used until the cecum is reached.
Infusion of a sufficient amount of water to render the lumen a slit to progress with the colonoscope.
Part of the infused water will be constantly suctioned back exchanging clean for opaque water.
Air pockets and residual feces will be always aspirated.
Withdrawal phase done using carbon dioxide insufflation.
|
Insertion using water exchange, withdrawal using CO2 insufflation.
|
|
Eksperymentalny: Water Exchange-AI
Insufflation not used until the cecum is reached.
Infusion of a sufficient amount of water to render the lumen a slit to progress with the colonoscope.
Part of the infused water will be constantly suctioned back exchanging clean for opaque water.
Air pockets and residual feces will be always aspirated.
Withdrawal phase done using air insufflation.
|
Insertion using water exchange, withdrawal using air insufflation.
