“…At present, there are many imaging diagnostic methods for biliary tract diseases, such as B-ultrasound, computed tomography, magnetic resonance imaging, etc. , which enable direct and vivid diagnosis of biliary obstruction[ 7 , 8 ]. Ultrasonic diagnosis of biliary ascariasis is non-invasive and easy, with high sensitivity, strong specificity and safety, and is often used as the first choice.…”

BACKGROUND Biliary ascariasis is rare but remains the most common parasitic infection in remote areas and in people with poor medical conditions. Here, we reported a case of biliary ascariasis in order to raise awareness of possible parasitic infections. CASE SUMMARY A 68-year-old female was admitted to the emergency room of the Affiliated Hospital of Guizhou Medical University on 28 September 2017, with chief complaint of pain in the right upper abdomen. Ultrasonography of the abdomen showed that the upper segment of the common bile duct was slightly dilated with parallel tubular structures, indicative of biliary ascariasis. Endoscopic retrograde cholangiopancreatography was performed under general anesthesia on 29 September 2017, and an adult Ascaris lumbricoides worm was observed. After the worm was removed from the bile duct, the patient’s pain immediately subsided. The patient was successfully cured, without any complications. CONCLUSION This report emphasizes the need for physicians to consider biliary ascariasis as a possible cause when treating cases of biliary colic.

“…16 En algunos casos de fascioliasis masiva o de resistencia al tratamiento oral, se ha considerado, según Villa-Gómez y Lazo Molina, el uso de la instilación transendoscópica de solución de povidona yodada al 2,5%, en una cantidad de 20 ml por 10 min, para garantizar la muerte definitiva de los parásitos adultos y de los huevos presentes en el árbol biliar. 8,17 El tratamiento antiparasitario de elección aceptado por la Organización Mundial de la Salud (OMS) es el triclabendazol 10 mg/kg en dosis única, 18,19 que es efectivo contra las formas maduras e inmaduras del parásito; sin embargo, se han reportado casos de resistencia al fármaco cuando se administra en monodosis en nuestro país, tanto en animales como en seres humanos, 20 y algunos estudios no recomiendan la monodosis por el riesgo de aparición de cepas resistentes de Fasciola hepatica. 10,21 Frente a ello, el Centro para el Control y Prevención de Enfermedades recomienda una doble dosis de triclabendazol 10 mg/kg cada 12 h y no aprueban el uso de otro medicamento alternativo en los humanos.…”

Hepatic fascioliasis is a parasitic disease caused by the fluke Fasciola hepatica. In the chronic phase of the disease, the adult form of the parasite adopts the bile ducts as the ideal environment to develop, causing them to dilate and simulating an obstructive jaundice process. The case of a 48-year-old woman is presented, who was admitted for jaundice, choluria and eight loss. After the corresponding complementary studies had been carried out, an endoscopic retrograde cholangiography (ERCP) was performed and an adult Fasciola hepatica parasite was extracted from the biliary tract. Subsequently, anthelmintic treatment with triclabendazole was started, resulting in a favorable evolution and resolution of the condition.

“…Finally, they reach the biliary system and mature into an adult form. 3 Clinical manifestations differ depending upon two different phases of the infection. A hepatic phase begins 4-12 weeks after ingestion of metacercerial cysts when they penetrate the hepatic parenchyma.…”

Hepatobiliary fascioliasis is one of the rare but important parasitic infection in endemic areas such as Pakistan. Clinical manifestations overlap with common clinical conditions such as hepatitis and biliary stones causing common bile duct obstruction. Fascioliasis is a zoonotic infection caused by a leaf-shaped organism known as Fasciola Hepatica. Humans are accidentally infected by consuming contaminated water or food, especially undercooked cattle and sheep liver or raw green vegetables. We report three cases with similar clinical manifestations presenting in two different cities in Pakistan. After detailed clinical evaluation and laboratory investigations, the diagnosis was established by abdominal ultrasound and diagnostic and therapeutic cholangiography. Patients were followed till complete resolution of their symptoms and normalisation of liver function tests.
