Much has been written about the utility of endoscopic ultrasound (EUS) in the diagnosis of chronic pancreatitis (CP). However, data correlating EUS findings with surgical pathology is lacking. The purpose of this study was to determine the EUS characteristics of patients with surgically proven CP. Methods: All patients with surgically proven CP between 1991 and 1996 were identified by a search of the Pathology Database. Any patient with a simultaneous diagnosis of adenocarcinoma and CP was excluded from analysis. By cross-referencing with the EUS Database, a cohort of patients with the surgical diagnosis of CP who had undergone EUS was identified. Endpsonographic characteristics included: inhomogeneity, echogenic main pancreatic duct (MPD) border, echogenic foci, MPD irregularity, small cystic spaces, focal hypoechoic region, peripancreatic lymphadenopathy (LN), tabular architecture, and calculi. Results: Twenty-eight patients met criteria for analysis. The frequency of EUS findings were: inhomogeneity 96%, echogenic MPD 88%, echogenic foci 75%, MPD irregularity 64%, small cystic spaces 46%, focal hypoechoic region 36%, peripancreatic lymphadenopathy 29%, tabular architecture 18%, and calculi 18%. Conclusions: (1) This study examines endosonographic characteristics or patients with surgically proven CP. (2) Inhomogeneity, echogenic MPD border and echogenic foci are the most common endosonographic findings in this subset of patients.
