    Biliary ascariasis, a common cause of adult biliary disease, can be effectively diagnosed using sonography. This noninvasive imaging technique accurately identifies worms in the bile duct and monitors their exit, aiding in patient management.

    Area of Science:

    • Medical Imaging
    • Parasitology
    • Gastroenterology

    Background:

    • Biliary ascariasis is a significant cause of biliary disease in regions like the Kashmir Valley.
    • It often presents similarly to gallstone disease, necessitating accurate diagnostic methods.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of sonography for biliary ascariasis.
    • To assess sonography's utility in monitoring worm expulsion from the bile duct.

    Main Methods:

    • Prospective evaluation of 28 patients with confirmed biliary ascariasis.
    • Sonography was performed, with findings compared to endoscopic retrograde cholangiopancreatography (ERCP).
    • Characteristic sonographic features of worms and associated biliary changes were documented.

    Main Results:

    • Sonography detected worms in the biliary tree in 85.7% (24/28) of patients.
    • Common findings included dilated bile ducts and characteristic echogenic worm structures.
    • Serial sonograms effectively monitored spontaneous worm exit in 18 patients.

    Conclusions:

    • Sonography is a simple, rapid, and noninvasive tool for diagnosing biliary ascariasis.
    • It is valuable for monitoring treatment response and worm expulsion.
    • This imaging modality can differentiate biliary ascariasis from other biliary diseases.
