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.
Bile ducts from the liver and the gallbladder join together to form the common bile duct. This duct drains into the small bowel and delivers bile to this portion of the small bowel known as the duodenum. Bile helps in the breakdown of undigested food and also gives color to bowel motions. Whenever a blockage occurs in the bile duct, the bile ducts become enlarged or dilated.
