|
|
Presence of foam
Lasso di tempo: week 2 (Colonoscopy visit)
|
The presence of foam using the CEBuS (Colon Endoscopic Bubble Scale), in which each colonic segment (right colon, transverse colon, left colon) is scored from 0 to 2 (0=no or minimal number of bubbles; 1=moderate amount of bubbles affecting 5-50% of the circumference, affecting the vision of the mucosa and requiring additional time to wash; 2=abundant bubbles occupying >50% of the circumference, obscuring the mucosa and require ring additional time to washing).
|
week 2 (Colonoscopy visit)
|
|
Presence of bubbles
Lasso di tempo: week 2 (Colonoscopy visit)
|
The presence of bubbles using the CEBuS (Colon Endoscopic Bubble Scale), in which each colonic segment (right colon, transverse colon, left colon) is scored from 0 to 2 (0=no or minimal number of bubbles; 1=moderate amount of bubbles affecting 5-50% of the circumference, affecting the vision of the mucosa and requiring additional time to wash; 2=abundant bubbles occupying >50% of the circumference, obscuring the mucosa and require ring additional time to washing).
