Design outcomes

Primary

Measure	Time frame
To evaluate the relevance of the optimal ultrasound speed (USS)for each degree of chronic pancreatitis (CP)according the Japanese diagnostic criterion for CP in 2019 (JDCCP2019) and to investigate whether the analysis of USS contributes to the diagnosis of CP.	—

Secondary

Measure	Time frame
