DBTP. Definition

Medical Definition: DBTP

Percutaneous transhepatic biliary drainage. A procedure used to drain bile and relieve the pressure caused by obstruction of the bile ducts. An x-ray the liver and bile ducts locates the blockage that impedes the flow of bile. They use images created by ultrasound to guide the installation of a cannula (tube) that stays in the liver. Bile drains through the tube into the small intestine or a collection bag outside the body. This procedure may relieve jaundice before surgery. Also called percutaneous transhepatic colangiodrenaje and percutaneous transhepatic biliary drainage.
