Abstract: Objective To investigate the utility of virtual endoscopy ultrasound Fly-Thru in the diagnosis of obstructive bile duct diseases.Methods One-hundred patients with obstructed bile duct diseases underwent Fly-Thru examination.All Fly-Thru images were reviewed by two radiologists with different experience.The capabilities of Fly-Thru for bile duct obstructive degree evaluation and distinguishing malignant lesion from benign one were assessed respectively.Results The accuracy and sensitivity of Fly-Thru image in obstruction degree evaluation were 70.59％ and 89.2％ (95％CI 74.6％-96.9％).The diagnosis accuracy of 2DUS for lesion characteristics increased from 80％ to 84％,accompany with Fly-Thru images,especially for lesions in common bile duct from 77.2％ to 86.0％ (x2 =14.399,P =0.001).Conclusions The virtual endoscopy ultrasound Fly-Thru is only partly capable to display the obstructed degree of some bile ducts,but it can improve the diagnostic accuracy of common bile duct diseases.
