Background: Ascariasis is very common in this part of the world. Biliary Ascariasis is rare but is the commonestextra-intestinal complication. Methods: This study was conducted at Ayub leaching Hospital, Abbottabad, a tertiary'care hospital. Five cases of biliary Ascariasis were studied from December 1999 to January 2001. History of passageof worms in stool or vomiting and abdominal pain was taken. After clinical evaluation. Stool Examination, Serumamylase, LFTs, and complete blood picture (CP) were done. Ultrasound abdomen was done as a basic tool fordiagnosis. All cases were given Piperazine. Spasmolytics were also given to relax sphincter of oddi to release theworms. Surgical opinions were also taken for each case. Results: About 80% Children were above 10 years of age.One case was 1 % years old. Most common symptom was right upper quadrant abdominal pain. Previous history ofpassage of worms in stool and vomitus was also present. Two children developed complications of Biliary Ascariasisi.e., Cholecystitis and Portal empyema and responded to antibiotics. All children became symptom free in about 48hours of treatment. Ultrasound was found to be a reliable, non-invasive, and quick tool for diagnosis and follow up.
