Abstract
A 51 year-old female with biliary ascariasis was reported. Suddenly she was complained of severe epigastralgia and back pain.
On admission, she had tenderness in her epigastric region. Liver, spleen and kidneys were not palpable. Laboratory data were within normal limit and ova of Ascaris were not found in her feces.
DIC showed a vague linear filling defect in the common bile duct. Further, it was confirmed as an obvious linear filling defect in the common bile duct, by the first ERCP. She was diagnosed as a biliary ascariasis and treated by an oral vermifuge (pyrantol pamoate 500mg).
After three days the second ERCP was done, but the previous linear filling defect was disappeared. Eight days after the oral vermifuge, adult Ascaris was found in her feces.
