Cannulation rates and technical performance evaluation of commericially available single-use duodenoscopes for endoscopic retrograde cholangiopancreatography: A systematic review and meta-analysis.

BACKGROUND

Single use duodenoscopes were developed to reduce the risk of infection transmission from contaminated reusable duodenoscopes. To this end, we examined various biliary interventions using single use duodenoscopes in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).

METHODS

Medline, Embase, Scopus, and Cochrane databases were searched from inception through Aug 2022 to identify studies reporting on the performance of single use duodenoscopes for ERCP.

RESULTS

Seven articles were included in the final analysis that included 642 patients (318 males). The Exalt Model D duodenoscope was used in most cases (88.8%) followed by the aScope Duodeno (11.2%) for ERCP. Most ERCPs had a complexity grade of 2 (n = 303) and 3 (n = 198). The pooled cumulative rate of successful cannulation was 95% (95% Confidence Interval (CI): 93-96%, I2=0%, P = 0.46). Sphincterotomy was successfully performed in all cases. The pooled cumulative rate of PEP was 2% (95% CI: 0.4-3.4%, I2=0%, P = 0.80). The pooled cumulative rate of total adverse events was 7% (95% CI: 4-10%, I2=47%, P = 0.08).

CONCLUSIONS

The results of this systematic review and meta-analysis show that single use duodenoscopes are associated with high cannulation rates, technical performance, and safety profile.
