The Gemelli Ultrasound Chronic Pancreatitis Score: A Non-invasive Tool for the Diagnosis of Chronic Pancreatitis

A dedicated ultrasound (US) score, the Gemelli Ultrasound Chronic Pancreatitis (USCP) score, could be useful in the follow-up of patients with chronic pancreatitis (CP). However, its role in the diagnosis of CP has not been investigated. We aimed to evaluate the role of the Gemelli USCP score in the diagnosis of CP and the agreement with standard imaging techniques. Ninety-three patients clinically suspected of having CP and referred to the pancreatic outpatient clinic of A. Gemelli Hospital for endoscopic ultrasound (EUS) were prospectively enrolled. All patients underwent pancreatic US to calculate the Gemelli USCP score. A receiver operating characteristic curve analysis was also performed to assess the performance of the US score in CP diagnosis. The Gemelli USCP score was inversely related to the Rosemont score for both total value (p < 0.0001) and each parameter evaluated (p < 0.0001). This score was significantly higher in patients with CP with an excellent area under the receiver operating characteristic curve (0.946) and the optimal cutoff of 5. Moreover, we found a significant correlation between the Gemelli USCP score and laboratory parameters related to pancreatic exocrine insufficiency (p < 0.0001). The development of a dedicated ultrasound score could be useful as a non-invasive tool in the diagnosis of CP.
