ERCP is regarded as the gold standard for imaging the biliary system and combines the advantage of diagnosis of biliary obstruction with therapeutic intervention, if required.
The results of the present study indicate that real-time PCR using fluorescence hybridization probes with a PNA clamping reaction and melting curve analysis may offer a promising method to accurately identify K-ras gene mutations in patients with biliary obstruction. The absence of post-PCR manipulation reduces the risk of carryover contamination and false-positive results.
The fundamental objectives of palliative transhepatic biliary drainage are to improve quality of life by relieving jaundice and pruritus, prevent cholangitis, and avert liver failure caused by progressive biliary obstruction.
