Most worthwhile investigation for detection of suspected pancreaticobiliary worms is?
A. UltrasoundB. CT
C. MRCP
D. ERCP
Ans. D.
Most cases of ascariasis can be diagnosed by the microscopic detection of characteristic mamillated ascaris eggs 65 by 45 mm. in fecal samples; Occasionally, patients present after passing an adult worm — identifiable by its large size and smooth cream-colored surface — in the stool or through the Mouth or nose; During the early transpulmonary migratory phase, when eosinophilic pneumonitis occurs, larvae can be found in sputum or gastric aspirates before
diagnostic eggs appear in the stool. The eosinophilia that is prominent during this early stage usually decreases to minimal levels in established infection. The large adult worms may be visualized, occasionally serendipitously, on contrast studies of the gastrointestinal tract. A plain abdominal film may reveal masses of worms in Gas-filled loops of bowel in patients with intestinal obstruction. Pancreaticobiliary worms can be detected by ultrasound and endoscopic retrograde Cholangio-pancreatography; the latter method also has been used to extract biliary ascaris worms.
