EUS Diagnostic Criteria for Chronic Pancreatitis: A Comparison of Conventional Versus Rosemont Criteria

OBJECTIVE: To compare the Rosemont criteria, which are graded features chosen by experts in 2007, versus the conventional criteria, which require ≥ 3-5 of the 9 features that are counted as equal, for the diagnosis of chronic pancreatitis by EUS. METHODS: This is a retrospective cohort study. EUS examinations were scored using both criteria, and the following categories compared: 3-CC versus consistent with chronic pancreatitis by RC; 3-CC versus consistent with and suggestive of chronic pancreatitis by RC; 5-CC versus consistent with chronic pancreatitis by RC; and 5-CC versus consistent with and suggestive of chronic pancreatitis by RC. RESULTS: There was a statistically significant difference between 3-CC and RC, either consistent with alone or both consistent with and suggestive of (p \u3c 0.0001). Comparing 5-CC and consistent with showed a statistical difference (p = 0.0014), but no difference comparing 5-CC to consistent with and suggestive of. CONCLUSION: CC diagnose more cases of chronic pancreatitis than RC when using 3-CC or when comparing 5-CC to consistent with chronic pancreatitis by Rosemont, indicating that the Rosemont criteria are more stringent
