Background: EUS has less than optimal interobserver agreement for the diagnosis of chronic pancreatitis. The newly developed Rosemont consensus scoring system includes weighted criteria and stricter definitions for individual features. Objective: The primary aim was to compare the interobserver agreement of standard and Rosemont scoring. Setting: Multiple tertiary-Care institutions. Intervention: Fifty EUS videos were interpreted by 14 experts. Each expert interpreted the videos oil two occasions: First, the videos were read by using standard scoring (9 criteria). Second, after viewing a presentation of the Rosemont classification, the same experts re-read the Videos by using Rosemont scoring. Main Outcome Measurements: Fleiss' kappa (K) statistics are reported with 95% confidence intervals (0). Results: The interobserver agreement was substantial (K = 0.65 [95% CI, 0.52-0.77]) for Rosemont scoring and moderate (K = 0.54 [95% CI, 0.44-0.66]) for standard scoring; however, the difference was not statistically significant (P = 0.12). Limitations: The sample size does not allow detection of differences in K of <0.25. Conclusion: Use of the Rosemont classification did not significantly increase interobserver agreement for EUS diagnosis of chronic pancreatitis compared with standard scoring.
