Clean Colon Software Program (CCSP), Proposal of a standardized Method to quantify Colon Cleansing During Colonoscopy: Preliminary Results
Background and study aims: Neoplastic lesions
can be missed during colonoscopy, especially
when cleansing is inadequate. Bowel preparation
scales have significant limitations and no objective
and standardized method currently exists to
establish colon cleanliness during colonoscopy.
The aims of our study are to create a software algorithm
that is able to analyze bowel cleansing
during colonoscopies and to compare it to a validate
bowel preparation scale.
Patients and methods: A software application
(the Clean Colon Software Program, CCSP) was
developed. Fifty colonoscopies were carried out
and video-recorded. Each video was divided into
3 segments: cecum-hepatic flexure (1st Segment),
hepatic flexure-descending colon (2nd
Segment) and rectosigmoid segment (3rd Segment).
Each segment was recorded twice, both
before and after careful cleansing of the intestinal
wall. A score from 0 (dirty) to 3 (clean) was then
assigned by CCSP. All the videos were also viewed
by four endoscopists and colon cleansing was established
using the Boston Bowel Preparation
Scale. Interclass correlation coefficient was then
calculated between the endoscopists and the software.
Results: The cleansing score of the prelavage colonoscopies
was 1.56\ub10.52 and the postlavage one
was 2,08\ub10,59 (P<0.001) showing an approximate
33.3% improvement in cleansing after lavage.
Right colon segment prelavage (0.99\ub10.69)
was dirtier than left colon segment prelavage
(2.07\ub10.71). The overall interobserver agreement
between the average cleansing score for the 4 endoscopists
and the software pre-cleansing was
0.87 (95% CI, 0.84\u20130.90) and post-cleansing was
0.86 (95% CI, 0.83\u20130.89).
Conclusions: The software is able to discriminate
clean from non-clean colon tracts with high significance
and is comparable to endoscopist evaluation
