The pediatric variable stiffness colonoscope may be superior to the standard colonoscope in some situations.
In this study, physicians from Australia evaluated 797 consecutive patients undergoing colonoscopy in an outpatient endoscopy center.
Of these patients, 384 had their procedure performed with a standard colonoscope, while the remaining 413 had their procedure performed with a pediatric variable stiffness colonoscope.
The research team regarded inability to negotiate the sigmoid colon within 10 minutes as a failure. If possible, failed patients were crossed-over to colonoscopy with the alternative instrument.
The physicians found that median time to the cecum was significantly faster in the pediatric variable stiffness group, compared with the standard group.

Overall, 3% of procedures failed.
The team found that there were 14 failures in the standard group. Of these, 13 patients were crossed-over to the variable stiffness colonoscope; 92% were successfully completed.
The team also determined that the pediatric variable stiffness colonoscope was superior in severe stenosing diverticular disease. They found that 7% of examinations with the pediatric variable stiffness colonoscope failed, compared with 66% with the standard colonoscope.
Dr Arthur John Kaffes's team concluded, "Intubation time was faster with the pediatric variable stiffness colonoscope, but use of this instrument was not associated with a superior cecal intubation rate compared with the standard colonoscope".
"However, in patients with severe stenosing diverticular disease, the intubation rate with the pediatric variable stiffness colonoscope was superior".
