[Transhepatic biliary drainage as a method in the diagnosis and treatment of XXXX ].

@entity1 @entity3883 @entity1087 @entity7252
Percutaneous transhepatic biliary drainage was performed on @entity1087 @entity1 , who had obstruction of the bile duct, in order to determine the exact site and nature of the @entity3883 . In the present series, six @entity1 were treated with external biliary drainage. Four of them received this treatment prior to radical surgery. In the remaining two cases the external drainage was a palliative procedure. In five @entity1 , the drainage catheter was internalized through the obstructed bile duct (internal biliary drainage). One of these @entity1 was subsequently treated with radical surgery. In two cases, the internal biliary drainage was palliative. In the two remaining cases, intraluminal selective irradiation was introduced via Iridium 192 flexible wires. Severe @entity7252 occurred in one @entity1 , who was successfully treated by lithotomy and "T" tube drainage. We conclude that the simplicity and low cost of these drainage procedures recommend them as extremely useful for the diagnosis and treatment of obstructive @entity1087 @entity1 .
