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.
A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the pancreas to the small intestine (the duodenum).Bile is a dark-green or yellowish-brown fluid secreted by the liver to digest fats. Much of the bile is released directly into the small intestine, but what remains is stored in the gallbladder.he 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.
