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 bile duct is long tube-like structure that connects the liver to the intestine and transports bile from the liver to the intestine. The top half of the bile duct is associated with the liver while the bottom half of the bile duct is associated the pancreas. The bile duct enters the part of the intestine called the duodenum into a structure called the Ampulla.
