Background and Purpose: The concept of early chronic pancreatitis was proposed in Japan with the aim to improve the prognosis of patients with chronic pancreatitis. Endoscopic ultrasonography plays an important role in early diagnoses, but is limited by its invasiveness and poor objectivity. Hence, this study aimed to determine the usefulness of transabdominal ultrasound real-time tissue elastography as a screening method for early chronic pancreatitis.
Methods: We retrospectively examined 73 patients who underwent simultaneous ultrasound real-time tissue elastography and endoscopic ultrasonography from 2011 to 2014. The correlation between feature values (MEAN, %AREA, COMP) calculated by real-time tissue elastography and the Rosemont classification of endoscopic ultrasonography diagnostic criteria for chronic pancreatitis, and the diagnostic ability of ultrasound real-time tissue elastography to recognize “indeterminate for chronic pancreatitis” findings, which correspond to early chronic pancreatitis, were evaluated.
Main Results: Based on the Rosemont classification, 26 patients were “normal”, 16 were “indeterminate for chronic pancreatitis”, 13 were “suggestive of chronic pancreatitis”, and 18 were “consistent with chronic ancreatitis”. There were significant correlations between the feature values (MEAN, %AREA, COMP) and the Rosemont classification (p < 0.001; ρ = –0.788, 0.779, and 0.489, respectively). The area under the curve for the ability of MEAN to diagnose “indeterminate for chronic pancreatitis” was 0.889 (sensitivity, 93.8%; specificity, 76.9%).
Conclusions: The feature values calculated by ultrasound real-time tissue elastography were correlated with the Rosemont classification. Ultrasound real-time tissue elastography may be a useful screening method for early chronic pancreatitis.
