Cysticers are disengaged in the duodenum, and some of the child worms pass through the intestinal wall, reach the abdominal cavity, drill into the liver by the liver envelope, and reach the bile ducts through migration. Another part of the child worm burrows into the intestinal mucosa and enters the liver through the mesenteric vein.
