OLIVEIRA, Diana de; CASTILLO, Yhonny; LOMBARDO, Gabriela  e  VILERA, María Fernanda. Biliary ascariasis with choledocolitiasis: an endoscopic retrograde cholangiopancreatography resolution. Case report. Endoscopia [online]. 2020, vol.32, n.3, pp.108-110.  Epub 11-Out-2021. ISSN 2444-6483.

Ascaris lumbricoides is a nematode that causes gastrointestinal diseases, with a higher prevalence in developing countries and in children. Biliary ascariasis is more common in adults, its prevalence is associated with poor sanitary conditions and humid soil conditions. We present the case of a 34-year-old female patient, with a history of choledocholithiasis resolved by retrograde endoscopic cholangiopancreatography (ERCP), who presented right hypochondrium pain of 1 month of evolution. Laboratory tests reported abnormal liver function tests. The fluoroscopic image revealed a choledochal dilation (14.3 mm) and left hepatic duct dilation, with multiple radiolucent images agglomerated in the proximal portion, consistent with choledocholithiasis; it was also noticed the presence of an elongated and motile radiolucent image consistent with a worm. A new ERCP was made, using the Dormia basket for the extraction of the stone, which also captured the worm.
