@entity2329 is as frequent a cause of adult biliary disease as @entity5990 in Kashmir Valley, India. In the present study, we prospectively evaluated the role of sonography in the diagnosis of @entity2329 and its utility in monitoring the exit of worms from the bile duct. Sonography was performed on 28 @entity1 with @entity2329 proven by endoscopic retrograde cholangiopancreatography. The bile ducts were dilated on sonography in 26 @entity1 . The characteristic sonographic features of worms in the bile duct were as follows: (a) a single, long, linear or curved echogenic structure without acoustic shadowing (2 @entity1 ); (b) multiple, long, linear, parallel echogenic strips, usually without acoustic shadowing (15 @entity1 ); (c) a thick, long, linear or curved, nonshadowing echogenic strip containing a central, longitudinal anechoic tube, probably representing the digestive tract of the worm (7 @entity1 ); and (d) characteristic movement of these long echogenic structures within the bile duct (8 @entity1 ). One @entity1 with pancreatic @entity2329 exhibited long, linear, nonshadowing echogenic strips in a dilated pancreatic duct. Other sonographic changes observed in these @entity1 were (a) @entity1085 (10 @entity1 ), @entity4 of the gallbladder wall (8 @entity1 ), sludge within the gallbladder (11 @entity1 ), a coiled echogenic structure within the gallbladder (1 @entity1 ); (b) multiple liver abscesses (1 @entity1 ); and (c) @entity788 (4 @entity1 ). Sonography detected worms in the biliary tree in 24 of 28 @entity1 (85.7%). Serial sonograms accurately demonstrated the spontaneous exit of worms in 18 @entity1 and the persistence of worms in 3 @entity1 . Sonography is a simple, rapid, and noninvasive method for diagnosis and follow-up of @entity1 with @entity2329 .
