In the present study, we prospectively evaluated the role of sonography in the diagnosis of biliary ascariasis and its utility in monitoring the exit of worms from the bile duct. Sonography was performed on 28 patients with biliary ascariasis proven by endoscopic retrograde cholangiopancreatography. The bile ducts were dilated on sonography in 26 patients. 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 patients); (b) multiple, long, linear, parallel echogenic strips, usually without acoustic shadowing (15 patients); (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 patients); and (d) characteristic movement of these long echogenic structures within the bile duct (8 patients). One patient with pancreatic ascariasis exhibited long, linear, nonshadowing echogenic strips in a dilated pancreatic duct. Other sonographic changes observed in these patients were (a) gallbladder distention (10 patients), edema of the gallbladder wall (8 patients), sludge within the gallbladder (11 patients), a coiled echogenic structure within the gallbladder (1 patient); (b) multiple liver abscesses (1 patient); and (c) edematous pancreatitis (4 patients). Sonography detected worms in the biliary tree in 24 of 28 patients (85.7%). Serial sonograms accurately demonstrated the spontaneous exit of worms in 18 patients and the persistence of worms in 3 patients. Sonography is a simple, rapid, and noninvasive method for diagnosis and follow-up of patients with biliary ascariasis.

The non-A, non-B hepatitis observed was a disease of young adults (29.8 +/- 15 years) with slight male predominance (1.4:1). Six of the 155 non-A, non-B cases had history of prior parenteral exposure, while 51 (33%) had a recent contact with another case of jaundice, suggesting that this form of hepatitis was spread by person-to-person contact. Fulminant hepatic failure occurred in 19 cases, and six (31.5%) of the 19 cases occurred in pregnant women. None of 90 non-A, non-B cases followed up six months later had developed chronic hepatitis. The acute sporadic non-A, non-B hepatitis described in Kashmir resembles epidemic non-A, non-B hepatitis epidemiologically and seems to be distinct from the non-A, non-B hepatitis described in the West.

Until now, there is no published study comparing the relative safety and efficacy of these two forms of treatment. In a prospective study, 33 hepatic hydatid cysts were randomly distributed to receive percutaneous drainage (10), albendazole (10 mg.kg-1.day-1 for 8 weeks) plus percutaneous drainage (12), and albendazole alone (11). Patients were serially assessed by clinical and biochemical examinations, ultrasonography, and hydatid serology. On serial ultrasonography, cysts attained heterogeneous echopattern in 18, uniform echogenicity in 11, and disappearance in 3. All 22 cysts treated with percutaneous drainage and only 2 (18.2%) cysts treated with albendazole alone reduced in size and change in echopattern (P < 0.01). Maximum size reduction was observed in cysts treated with a combination of percutaneous drainage and albendazole (P < 0.05). Complications observed with drainage were cyst infection in 2 patients, fever in 3, cyst biliary rupture in 1, and urticaria in 2. These were managed successfully without any mortality. Three patients who received albendazole developed reversible elevation of liver cell enzymes. It was concluded that percutaneous drainage with albendazole therapy is an effective form of management for hepatic hydatid cysts.
