Takeaway
- A mixed-modality training program for the real-time optical diagnosis of colorectal polyps significantly improved the ability of endoscopists to achieve PIVI (Preservation and Incorporation of Valuable Endoscopic Innovations) benchmarks.
Why this matters
- There is an unmet need for improved training in endoscopic characterization of colorectal polyps using narrow-band imaging (NBI) and optical diagnosis of sessile serrated lesions (SSLs).
Study design
- Study to asses a quality improvement program in 15 endoscopists with limited experience in NBI-based prediction of polyp histology.
- The study comprised 2 phases:
- Phase 1: Ex vivo self-training module for basic skills before in vivo real-time optical diagnosis.
- Phase 2: Results disseminated from in vivo phase 1, email-based ex vivo training for reeducation before a second round of real-time in vivo optical diagnosis.
- Funding: Seoul National University Hospital Research Fund.
Key results
- Accuracy with high confidence was 79.4% in phase 1 and 85.1% in phase 2 (P<.001>
- Negative predictive values (NPV) for diminutive neoplastic polyps were 82.1% in phase 1 and 92.5% in phase 2.
- 80.7% concordance of (optical/histology-based) surveillance intervals in phase 1; 89.7% in phase 2.
Limitations
- Limited sample size.
