Dr. Lee acknowledged the study’s limitations: it was not a randomized controlled trial, certain risk factors (family history, NSAID use) were not accounted for, and the scoring tools were also not validated, especially for bowel prep quality.
"Our study probably raises more questions than it answers," he acknowledged. Further study of geographical variations, time of day variations, and nontechnical colonoscopy factors should be performed, he suggested. Meanwhile, at least one current recommendation can be emphasized: that colonoscope withdrawal time should be at least 10 minutes, he said.
Dr. Lee had no relevant financial disclosures.
