One important result of lake and reservoir enrichment is increased growth of microscopic floating plants, algae, and the formation of dense mats of larger floating plants such as water hyacinths (Photos 1 and 2) and Nile cabbage.
What is percutaneous biliary drainage? Percutaneous transhepatic biliary drainage is a procedure where a small, flexible, plastic tube is placed through the skin into the liver in order to drain an obstructed bile duct system. The liver produces bile which aids digestion of fats.
The biliary duct (the duct from the gallbladder) also opens into the common hepatic duct. The bile duct from this point onward is known as the common bile duct or choledochus. Before emptying into the small intestine the common bile duct passes through the pancreas.he biliary duct (the duct from the gallbladder) also opens into the common hepatic duct.
