Pediatric Cholecystostomy and Biliary Drain Placement

One of the many functions of the liver is the production of bile, a substance integral to the digestion and absorption of food. Bile is produced by the liver cells (hepatocytes) and then flows into small tubules in the liver called ducts. Small ducts come together to form larger ducts and eventually, ducts from the right and left side of the liver merge to form the common hepatic duct. When it is not needed, the bile travels from the common hepatic duct into the cystic duct, which leads to the gall bladder where bile is stored. When needed by the body, bile flows from the common hepatic duct or cystic duct into the common bile duct, the large duct formed from the merging of the common hepatic and cystic ducts. From this point, bile flows through a small sphincter and into the small bowel. The pancreatic duct joins the common bile duct just before the common bile duct entry into the small bowel. The biliary system can become blocked at any level along this pathway.
