The Ascaris is a cosmopolitan parasite, frequent in children in the whole world, since it does not need any special climatic or environmental factors for its growth and development. It enters the organism by intake of eggs, completing a histicaltissue transalveolar capillary cycle in its development returning to the jejunum as adult parasite. In this stage it has an exaggerated mobility when the homoeostasis is altered (principally fever in children), being able to migrate to different locations causing diverse complications, among which the migration to bilious conducts stands out with the ascaris´ enclosure. We present the case of an 8 year-old school boy, who came from the Beni with extremely severe abdominal pain on the right side with an evolution of 10 days and irradiation to the epigastrium. The boy had been admitted to the hospital of San Borja, and since his problem was not solved, he was transferred to the Hospital del Niño in la Paz, where two mobile ascaris were found inside the gall bladder and the choledoco in the echography. Pamoato of pirantel was administered, without initial decrease of the pain. Due to the intensity, and the time of evolution of the pain, surgery was considered. When the pain was attenuated an echographic control was made that showed the spontaneous exit of the parasites. For this reason, the conservative treatment was continued with a positive evolution.
