Background and study aim: Effective colonoscopy depends on adequate visualization of the intestine, which might
be ensured by intraprocedural use of a cleansing device. We investigated the performance
of a novel endoscopic device with regard to cleanliness, safety, and tolerability
during colonoscopy, compared with standard cleansing.
Patients and methods: At a single center, colonoscopy patients in whom the cecum was accessed and at least
one bowel segment was inadequately cleansed were assigned to either use of a disposable
catheter cleansing device (JetPrep), used through the endoscope working channel, or
standard manual cleansing using a 50-ml syringe. The cleansing quality, for each segment
and before and after irrigation, was recorded using a 4-point scale ranging from excellent
(grade 1, no more than small bits of adherent feces) to poor (grade 4, large amount
of fecal residue).
Results: 38 patients were included, 19 in each group. Reasons for referral included colorectal
cancer screening (52 %), or blood loss (31 %). Each segment showed improvement after
cleansing with JetPrep. Overall cleansing grade improved by a mean of 0.74 points
(standard deviation [SD] 0.82) in the investigation group compared with 0.19 (0.40)
in the control group (P < 0.0001), and right colon cleansing improved by 1.59 points (0.71) versus 0.31 (0.48)
in the controls (P < 0.0001). There was no significant difference in procedure time between the groups.
No adverse events or side effects were encountered.
Conclusions: The JetPrep disposable catheter device is safe and efficient for intraprocedural
cleansing of a suboptimally prepared colon, allowing higher quality colonoscopy.
