After excysting in the duodenum, the
metacercariae migrate through the ampulla of Vater into the bile ducts,
where they mature into adult worms within 4 weeks and deposit yellow,
operculated eggs. During ERCP, the physician will often give the
patient an intravenous dose of glucagon to relax the gut to facilitate
the cannulation of the ampulla of Vater, which contains the narrow mouth
of the pancreatic and bile ducts. |
