Abstract: The etiology of distal common bile duct (CBD) dilatation is complex. Linear-array endoscopic ultrasonography (EUS) can not only visualize the distal and surrounding structures of the bile duct closely but also obtain pathological specimens by fine-needle aspiration, which provides an important basis for the diagnosis and differential diagnosis. The purpose of this study was to evaluate the diagnostic value of linear-array EUS in the etiology of distal CBD dilatation. Patients with distal CBD dilatation underwent linear-array EUS in the endoscopic center of The Second Affiliated Hospital of Soochow University and Traditional Chinese Medicine Hospital of Kunshan were collected from January 2015 to June 2019. The pathology results after surgery, endoscopic pathology, computed tomography (CT), and magnetic resonance imaging (MRI) results were retrospectively analyzed. The diagnostic accuracy of linear-array EUS and CT or MRI was compared. For the diagnosis of choledocholithiasis, the diagnostic accuracy of linear-array EUS was 97.5%, which was significantly higher than that of MRI (86.36%) and CT (89.74) (P < 0.001 and 0.006, respectively). The diagnostic accuracy of linear-array EUS for periampullary tumors was 93.75%, which was higher than MRI and CT with an accuracy of 82.73% and 80.34% (P = 0.004 and 0.001, respectively). Linear EUS was effective for the etiological diagnosis of distal CBD dilatation.
